Expandable baton structure with smasher

Abstract

The present invention is to provide an expandable baton with a smasher at the front end of an inner rod thereof, wherein an impact groove, a tapered groove, an aligning groove, and a compression force application groove are sequentially formed in the smasher and the front end of the inner rod. A compression spring can push an impact block in the compression force application groove toward the impact groove in order to position a smashing rod in the corresponding grooves and expose a front conical portion of the smashing rod. When the conical portion is forcibly pressed against an object to-be-smashed, the smashing rod is partially pressed against the wall of the tapered groove and is thrusted into a hitting groove in the impact block upon aligning with the axis of the impact block. The impact block is then driven outward by the compression spring and drives the conical portion to smash the object.

What is claimed is: 
     
         1 . An expandable baton structure with a smasher, comprising:
 an expandable baton comprising an outer tube and an inner rod, wherein the outer tube is configured to be gripped by a user, and the inner rod is retractable into the outer tube so that only a front end of the inner rod is exposed outside a front end of the outer tube; and   the smasher, provided at the front end of the inner rod, wherein an impact groove, a tapered groove, an aligning groove, and a compression force application groove are sequentially formed, in a front-to-rear direction, in the smasher and the front end of the inner rod and are in communication with one another; the smasher has a front end formed with an aperture; the aperture is in communication with the impact groove, the tapered groove, the aligning groove, and the compression force application groove sequentially; the aperture has a smaller diameter than the impact groove; the tapered groove tapers from a rear end of the impact groove toward a front end of the aligning groove and has a wall forming a first tapered pressing surface; the aligning groove has a smaller diameter than the impact groove and the compression force application groove; and the smasher comprises:   a smashing rod;   an impact block movably positioned in the compression force application groove, wherein the impact block has a front end configured to be pressed against a wall portion of the compression force application groove that is adjacent to the aligning groove, the front end of the impact block is concavely provided with a hitting groove corresponding to the aligning groove, and the hitting groove has a smaller diameter than the aligning groove; and   a compression spring positioned in the compression force application groove, wherein the compression spring has two ends respectively pressed against a rear end of the impact block and a wall portion of the compression force application groove that is away from the aligning groove, in order to push the impact block toward the aligning groove such that the front end of the impact block pushes a rear end of the smashing rod and thereby positions the smashing rod in the impact groove, the tapered groove, and the aligning groove, causing a conical portion at a front end of the smashing rod to pass through the aperture and be exposed outside the front end of the smasher;   wherein when the conical portion is pressed against a to-be-smashed object and is subjected to a force applied through the expandable baton, the rear end of the smashing rod is displaced toward the compression force application groove; and when a second tapered pressing surface formed by a wall of a middle section of the smashing rod is gradually pressed against the first tapered pressing surface, and the middle section of the smashing rod is gradually guided by the aligning groove into alignment with an axis of the impact block such that a rear section of the smashing rod instantly extends into the hitting groove, the impact block is driven outward by huge elastic energy accumulated in the compression spring, hits the rear end of the smashing rod, and thereby drives the conical portion at the front end of the smashing rod to smash the to-be-smashed object.   
     
     
         2 . The expandable baton structure of  claim 1 , wherein the rear section of the smashing rod has a longitudinal length greater than a longitudinal depth of the hitting groove. 
     
     
         3 . The expandable baton structure of  claim 2 , wherein the smasher further comprises an eccentric spring, and the eccentric spring is positioned in the impact groove and the tapered groove and has two ends respectively pressed against the smashing rod and the wall of the tapered groove in order to push the smashing rod toward the aperture. 
     
     
         4 . The expandable baton structure of  claim 3 , wherein the smashing rod comprises a first smashing rod and a second smashing rod, the first smashing rod has a front end provided with the conical portion, and the two ends of the eccentric spring are respectively pressed against the second smashing rod and the wall of the tapered groove in order for a front end of the second smashing rod to push a rear end of the first smashing rod toward the aperture, thereby causing the conical portion at the front end of the first smashing rod to pass through the aperture and be exposed outside the front end of the smasher. 
     
     
         5 . The expandable baton structure of  claim 4 , wherein the smasher further comprises a base; the impact groove, the tapered groove, the aligning groove, and the compression force application groove are sequentially formed, in the front-to-rear direction, in the base and are in communication with one another; and the base has a front end formed with the aperture. 
     
     
         6 . The expandable baton structure of  claim 5 , wherein the base comprises:
 a rear base portion integrally formed with the front end of the inner rod, the compression force application groove being provided in the rear base portion;   a middle base portion having a rear end fixed to a front end of the rear base portion by threaded connection, the tapered groove and the aligning groove being provided in the middle base portion; and   a front base portion having a rear end fixed to a front end of the middle base portion by threaded connection, the front base portion further having a front end formed with the aperture, the impact groove being provided in the front base portion.   
     
     
         7 . The expandable baton structure of  claim 5 , wherein the base comprises:
 a rear base portion having a rear end fixed to the front end of the inner rod by threaded connection, the compression force application groove being provided in the rear base portion;   a middle base portion having a rear end fixed to a front end of the rear base portion by threaded connection, the tapered groove and the aligning groove being provided in the middle base portion; and   a front base portion having a rear end fixed to a front end of the middle base portion by threaded connection, the front base portion further having a front end formed with the aperture, the impact groove being provided in the front base portion.   
     
     
         8 . The expandable baton structure of  claim 5 , wherein the base comprises:
 a rear base portion provided therein with the compression force application groove;   a middle base portion having a rear end fixed to a front end of the rear base portion by threaded connection, the tapered groove and the aligning groove being provided in the middle base portion; and   a front base portion having a rear end with an outer periphery and an inner periphery, the outer periphery being fixable to the front end of the inner rod by threaded connection, the inner periphery being fixed to a front end of the middle base portion by threaded connection, the front base portion further having a front end formed with the aperture, the impact groove being provided in the front base portion.
