Striking apparatus

Abstract

A striking apparatus mainly includes a base, a plastic rod body formed by way of blow molding, and a striking portion. The rod body is integrally and transversally extended to form a connection rod. A helical spring is disposed between the connection rod and the striking portion. The striking portion externally forced can rapidly restore to its original state by the restoring resilience of the helical spring.

1 . A striking apparatus, mainly comprising:
 a base having a chamber; and   a rod body disposed on the base, wherein the rod body is integrally formed by way of plastic injection molding and is integrally and transversally extended to form at least one connection rod, a surface of the connection rod is integrally injection molded to form an external thread to be screwed to one end of a helical spring, and the other end of the helical spring is to be connected to a striking portion.   
   
   
       2 . The striking apparatus according to  claim 1 , wherein the rod body is integrally formed by way of plastic blow molding, the striking portion comprises a link and a striking block, one end of the link is connected to the helical spring and is fixed by a screw, the other end of the link is formed with an engaging tooth, the striking block is a hollow plastic structure formed by way of blow molding, the striking block has an extended end portion formed with a two-side toothed portion, each of surfaces of the two-side toothed portion may be engaged with the engaging tooth of the link, an adjusting bolt is disposed between the two-side toothed portion and the engaging tooth, and the adjusting bolt is rotated so that up and down swinging angles of the striking block may be adjusted and fixed. 
   
   
       3 . The striking apparatus according to  claim 2 , wherein the rod body is a multi-stage assembled structure, a soft pad having a through hole is disposed on each of two sides of the striking block, a projecting positioning body is disposed on the striking block, the positioning body may penetrate through the through holes of the soft pads, and a protection sheath covers surfaces of the striking block and the soft pad.
