Embodiment Construction

[0029] see Figure 1 to Figure 6 As shown, the present invention is an "improved wrench tool structure". The present invention does not limit the type of wrench, and it can be applied to the type of wrench that has a ratchet block and a ratchet, such as a ratchet wrench, a socket wrench, etc., which include a The wrench body 1 is provided with a perforation 11 through the head end, and a direction control groove 12 is provided on one side to communicate with the perforation 11, a ratchet 2 is rotatably arranged in the perforation 11, and the ratchet 2 is provided with several ratchets 21; A ratchet block 3, which is arc-shaped, is accommodated in the direction control groove 12, and the ratchet block 3 is provided with a main tooth 31, a plurality of first auxiliary teeth 32 and a plurality of second auxiliary teeth 33, the number of The first auxiliary teeth 32 and the second auxiliary teeth 33 are respectively located on the left and right sides of the main tooth 31 (in this...

Abstract

The invention relates to an improved wrench tool structure which comprises a wrench body. A ratchet wheel is provide with a plurality of ratchets; each first auxiliary tooth and a corresponding second auxiliary tooth of a ratchet block are respectively positioned on two sides of a corresponding main tooth; when the ratchet block is meshed towards a first direction and a second direction, each main tooth is meshed with the optional ratchet, two sides of each main tooth cling to tooth surfaces of the corresponding ratchet, opposite tooth surfaces of the multiple first auxiliary teeth and the multiple second auxiliary teeth are meshed with the multiple ratchets, and gaps are reserved between reverse tooth surfaces of the various first auxiliary teeth and the various second auxiliary teeth and the tooth surfaces of the various ratchets. The improved wrench tool structure has the advantages that when the ratchet block is meshed with the ratchet wheel towards the first direction or the second direction, contact areas of the opposite tooth surfaces of the first auxiliary teeth and the second auxiliary teeth of the ratchet block and the tooth surfaces of the ratchets are small, accordingly, tooth jumping can be smoothly carried out by the ratchet block, and abrasion loss of the main teeth, the first auxiliary teeth and the second auxiliary teeth can be reduced.

Description

technical field [0001] The present invention mainly relates to an improved structure of a wrench tool, in particular to a structure of a wrench tool in which a ratchet block and a ratchet can smoothly skip teeth and reduce wear of the ratchet block. Background technique [0002] The wrench tool uses the principle of leverage to pull the screwed workpiece to achieve the effect of tightening or loosening, and the components of various industries can be assembled and combined by the screw. Firmware is assembled and fixed with different strengths of torsion, such as heavy industries such as aviation, shipbuilding, and cars. The parts and components must be assembled with a considerable strength of torsion to achieve a solid structure that can withstand the impact of air pressure and power. Therefore, in order to be able to apply Due to the strong torsion of the parts and components, various businesses have continuously refined and improved the structure of the wrench. [0003] ...
