Abstract

The invention relates to a ratchet wheel and discloses a ratchet wrench reversing structure. The ratchet wrench reversing structure comprises a head holder (1), a ratchet (2), a clamping part (3), a handle (4), an elastic linkage component (5), a pivot (6) and two elastic positioning components (7), wherein an accommodating hole (10) for penetrating through the upper and lower surfaces of the head holder (1) is formed in the head holder (1); two parallel lugs (11) and a pivot groove (12) formed between two lugs (11) are arranged on the head holder (1); a clamping groove (18) penetrating through the pivot groove (12) is formed in the lateral side of the accommodating hole (10); the racket (2) is rotationally combined in the accommodating hole (10) of the head holder (1); the racket (2) comprises a drive part (20) and an external toothed part (21) at the periphery of the racket (2). The ratchet wrench reversing structure has good structural strength, increasing of service life, is easy in manufacturing and assembling and low in cost and the like.

Description

technical field [0001] The invention relates to a reversing structure using a handle of a ratchet wrench to control the rotation direction, in particular to a reversing structure of a ratchet wrench with the advantages of good structural strength, prolonging service life, easy manufacture and assembly, and low cost. Background technique [0002] The reversing structure of the ratchet wrench in the prior art, as shown in the U.S. Patent No. US8245602B2, is provided with a round groove opening upwards on the head seat and a shaft block located at one end of the handle, and then a cover is arranged to seal the round groove On the opening of the shaft block, the shaft block is limited in the circular groove, and the necked section of the handle can swing left and right in it by using the radial gap on one side of the circular slot, so that the shaft block and the ratchet block can be elastically linked, thereby achieving Toggle the purpose of the ratchet steering. However, the ...
