Rotating-force adjusting device for a toy gun

Abstract

A rotating-force adjusting device for a toy gun has a gun body, a mounting tube, a driven element and a driving element. The gun body has an outer shell and an inner barrel. The mounting tube is mounted around the inner barrel and has a pressing block. The driven element is mounted in the outer shell, is pressed against the mounting tube and has an extending wing. The extending wing is formed on and protrudes curvedly from an upper end of the driven element and has a protruding post above the pressing block. The driving element is movably mounted in the outer shell, is pressed against the extending wing and has a main body, a turning tab and a guiding groove.

What is claimed is: 
     
         1 . A rotating-force adjusting device for a toy gun comprising:
 a gun body having
 an outer shell; and 
 an inner barrel mounted in the outer shell and having an inner end; 
   a mounting tube being elastically deformable, mounted around the inner end of the inner barrel in the outer shell and having
 an external surface; 
 an internal surface; 
 a top segment; and 
 a pressing block formed on and protruding downwardly from the internal surface of the mounting tube at the top segment of the mounting tube; 
   a driven element mounted in the outer shell, pressed against the mounting tube and having
 an inner side facing the external surface of the mounting tube; 
 an outer side; 
 an upper end; 
 a lower end; and 
 an extending wing being elastic, formed on and protruding curvedly from the upper end of the driven element and extending to the top segment of the mounting tube and having
 a free end extending to the top segment of the mounting tube; 
 a bottom side; 
 a top side; and 
 a protruding post formed on and protruding downwardly from the bottom side of the extending wing at the free end above the pressing block of the mounting tube; and 
 
   a driving element movably mounted in the outer shell, pressed against the extending wing of the driven element and having
 a main body movably mounted in the outer shell and having
 an inner side facing the external surface of the mounting tube and being opposite to the inner side of the driven element; 
 an outer side; 
 a bottom end; and 
 a top end extending above the top side of the extending wing to enable the inner side of the main body at the top end to press against the top side of the extending wing; 
 
 a turning tab formed on and protruding from the outer side of the main body, the turning tab movably connected to the outer shell and extending out of the outer shell; and 
 a guiding groove formed in the inner side of the main body from the top end to the bottom end of the main body for mounting the main body around the extending wing of the driven element and to enable the main body to press against the outer shell and the extending wing, and the guiding groove having a depth gradually deepened from the bottom end to the top end of the main body. 
   
     
     
         2 . The rotating-force adjusting device as claimed in  claim 1 , wherein the turning tab is formed on and protrudes from the outer side of the main body near the bottom end of the main body. 
     
     
         3 . The rotating-force adjusting device as claimed in  claim 2 , wherein the driven element has a holding segment formed in the outer side of the driven element at the lower end of the driven element and securely mounted in the outer shell. 
     
     
         4 . The rotating-force adjusting device as claimed in  claim 1 , wherein the driven element has a holding segment formed in the outer side of the driven element at the lower end of the driven element and securely mounted in the outer shell. 
     
     
         5 . The rotating-force adjusting device as claimed in  claim 3 , wherein the outer shell is composed by two half-shells that are respectively a first half-shell and a second half-shell. 
     
     
         6 . The rotating-force adjusting device as claimed in  claim 5 , wherein
 the first half-shell has
 a mounting segment; 
 a barrel segment; 
 an internal surface; 
 a positioning recess formed in the internal surface of the first half-shell at the mounting segment of the first half-shell; 
 a holding recess formed in the internal surface of the first half-shell at the mounting segment of the first half-shell; and 
   the second shell detachably connected to the first half-shell and has
 a barrel segment connected to the barrel segment of the first half-shell; 
 a mounting segment connected to the mounting segment of the first half-shell; 
 an internal surface; 
 an external surface; and 
 an adjusting slot formed through the internal surface and the external surface of the second half-shell at the mounting segment of the second half-shell, and the adjusting slot having
 an upper end; 
 a lower end; and 
 multiple engaging teeth formed on and protruding from the internal surface of the second half-shell beside the adjusting slot; 
 
   the mounting tube has a positioning protrusion formed on and protruding from the external surface of the mounting tube and mounted securely in the positioning recess of the first half-shell to hold the mounting tube between the half-shells;   the holding segment of the driven element is securely mounted in the holding recess of the first half-shell;   the main body is movably mounted in the second half-shell; and   the turning tab is movably connected to the second half-shell, extends out of the external surface of the second half-shell via the adjusting slot and has an engaging protrusion formed on and protruding from the outer side of the main body adjacent to the turning tab and selectively engaging one of the engaging teeth of the adjusting slot to adjust the position of the main body relative to the driven element, the mounting tube and the second half-shell.   
     
     
         7 . The rotating-force adjusting device as claimed in  claim 6 , wherein
 the gun body has an outer barrel mounted around the barrel segments of the half-shells and abutting the mounting segments of the half-shells; and   the inner barrel is mounted in the outer barrel and has an inner end extending to the mounting segments of the half-shells.
