TWI285149B - Improvement of reciprocating structure for wrench - Google Patents

Abstract

This invention relates to an improvement of reciprocating structure for wrench. The improvement of reciprocating structure for wrench mainly comprises a wrench main body and a flat portion. The wrench main body is provided with a box end inserting opening part at least at one end. The inner edge of the box end inserting opening part is surroundingly provided with an abutting part composed of a plurality of ratchets. The efficiency of locking and turning the screw member can be achieved by the abutting part. Further, the predetermined location of the abutting part is provided with a groove-shaped locking part capable of being used for an elastic member with round spring shape to be lock-provided. The flat portion is provided at one end of the abutting part and the diameter of the flat portion is slightly greater than that of the abutting part with ratchets. The screw member can be adjusted and received in the flat portion by the design of the flat portion, to make the wrench in idling state, so as to achieve the efficacy of reverse restoration of wrench main body. This invention is indeed a creation of great practical value for the industry.
