Problems solved by technology

However, the existing universal ratchet wrench is mainly a traditional self-tightening ratchet wrench. When clamping nuts of different sizes, it needs to be adjusted many times to suit different nuts. Therefore, it is time-consuming, laborious, and inconvenient to use. It wears heavily on the surface of the nut. When it is used for a heavily corroded nut, the nut may be squeezed and deformed, and it can no longer be adjusted with a ratchet wrench. Moreover, some narrow spaces and corners cannot work normally.

Abstract

The invention provides a wrench structure applied in the technical field of wrench equipment, wherein the wrench body (1) of the wrench structure is provided with a cavity (2), and the rotating shaft (3) on the wrench body (1) passes through the cavity part (2), a wrench handle (4) is installed at one end of the rotating shaft (3), a chain gear (5) is arranged on the rotating shaft (3), one end of the chain (6) is connected with the wrench body (1), and the other end of the chain (6) passes through In the gap between the chain gear (5) and the wrench body (1), the chain (6) meshes with the chain gear (5), and the wrench body (1), chain gear (5), and chain (6) form nut parts to fasten Cavity (7), the wrench structure of the present invention has a simple structure, can save time and effort to complete the disassembly of nuts, shafts, cylindrical rods and other parts, adapt to the disassembly requirements of nuts, shafts, and cylindrical rods of different sizes, and ensure the disassembly of nuts, shafts, etc. , Effectively prevent loosening of cylindrical rods and improve disassembly efficiency.

Description

technical field [0001] The invention belongs to the technical field of wrench equipment, and more specifically relates to a wrench structure. Background technique [0002] The universal ratchet wrench is the main device for disassembling nut parts. When in use, first adjust the size of the wrench, lock the nut parts, and pull the wrench to disassemble the nut parts. The universal ratchet wrench has the advantages of one wrench with multiple functions, convenient use, high efficiency, firmness and reliability, light weight and easy portability, etc., and is widely used. However, the existing universal ratchet wrench is mainly a traditional self-tightening ratchet wrench. When clamping nuts of different sizes, it needs to be adjusted many times to suit different nuts. Therefore, it is time-consuming, laborious, and inconvenient to use. It wears heavily on the surface of the nut, and when it is used for a heavily corroded nut, the nut may be squeezed and deformed, and it canno...
