Wrench for assembly and manufacturing method thereof

Abstract

The invention discloses a wrench for assembly and a manufacturing method thereof. The wrench comprises a wrench body, a tightening mechanism is arranged at one end of the wrench body, a spraying mechanism is arranged in the wrench body, and a lubricating mechanism is arranged on the side wall of the wrench body. The tightening mechanism comprises a driving assembly and a hydraulic pipe arranged at the tail end of the driving assembly, a transmission rod is movably arranged in the hydraulic pipe, and a resistance rod is fixedly connected to the side wall of the transmission rod. The spraying mechanism comprises an extrusion plate movably arranged in the wrench body, a first spring is fixedly connected to the side wall of the extrusion plate, and a protruding block is fixedly connected to the side wall, away from the first spring, of the extrusion plate. The resistance rod arranged at the end of the transmission rod abuts against the other clamping rod, fastening of a screw is achieved in the process of repeatedly pinching an extrusion ball, the wrench does not need to be repeatedly disassembled for angle adjustment in the area with the small moving space, more manpower and time are saved, and the assembling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wrenches, in particular to a wrench for assembly and a manufacturing method thereof. Background technique [0002] A wrench is a commonly used installation and disassembly tool in life, which is used to twist bolts or nuts. There are basically two types of wrenches, dead wrenches and live wrenches. The opening width of the movable wrench can be adjusted within a certain range, and it is a tool used to fasten and loosen nuts and bolts of different specifications. The adjustable wrench is composed of a head and a handle. The head is composed of a movable plate lip, a mechanical lip, a plate mouth, a turbine and a shaft pin. [0003] A wrench is a commonly used installation and removal tool. It is a hand tool that uses the principle of leverage to twist bolts, screws, nuts, and other openings or casings that are threaded to hold bolts or nuts. [0004] When the traditional wrench loosens and disassembles ...

AI Technical Summary

Problems solved by technology

[0004] When the traditional wrench loosens and disassembles the screw in the area with small twisting space, the angle of the wrench is small each time, so it is necessary to continuously disassemble the wrench from the screw and adjust the angle to rotate, wasting a lot of time. Manpower and time, and lack of lubricating equipment in the process of screwing and dismounting will cause the screws to freeze or slip, and the construction personnel will easily remember whether the screws are tightened or not during the long-term installation, removal and cleaning process, which will cause safety hazards , so there is a need for an assembly wrench and a manufacturing method thereof
