Small space socket head cap screw mounting and dismounting tool

Abstract

The invention relates to a small space socket head cap screw mounting and dismounting tool, belongs to mounting and dismounting tools in the technical field of mechanical installation and aims at solving the technical problem of providing small space socket head cap screw installation and removal tools. According to the technical scheme, the small space socket head cap screw mounting and dismounting tool comprises a long-handle socket head wrench, a head connecting plate, an elastic pressing and fixing unit, a screw and a socket head cap screw. The elastic pressing and fixing unit comprises a fixing ring, a threaded hole, a hollow screw, a hollow nut, a spring, a steel ball, a 120-degree cone angle hole and the like. The steel ball is mounted in the hollow screw and the spring is mounted above the steel ball and pressed by the inner surface of the hollow nut to form the elastic pressing and fixing unit. The long-handle socket head wrench is fixed to the fixing ring of the elastic pressing and fixing unit, the socket head cap screw is mounted in a socket head cap screw hole in the fixing ring, and the socket head cap screw and the socket head wrench are formed into a whole to form the small space socket head cap screw mounting and dismounting tool.

Description

technical field [0001] The invention belongs to the technical field of mechanical installation and relates to a tool for installing and dismounting hexagonal socket screws in a small space. Background technique [0002] In a narrow space, the fixing or dismounting of the hexagon socket screws used for positioning and installation of the mechanical structure is usually done through the hexagonal wrench, which is a general tool in the technical field of mechanical installation. [0003] The closest prior art with the present invention is the Allen wrench commonly used in machinery industry installation. Such as figure 1 As shown, including hexagonal wrench 1 and hexagonal screw 2. [0004] Place the inner hexagon screw 2 in the hole of the part to be fixed, and use the inner hexagon wrench 1 to fix the inner hexagon screw 2. [0005] The main problem existing in the prior art is: some hexagon socket head screws that need to be fixed have a small installation space and are l...

AI Technical Summary

Problems solved by technology

[0005] The main problem existing in the prior art is: some hexagon socket head screws that need to be fixed have a small installation space and are located in a relatively deep place. During installation, the Allen wrench 1 cannot be put into the head socket hole of the hexagon socket head screw 2. It also cannot be accurately placed in the screw hole, and the inner hexagonal screw 2 cannot be fixed, so that the mechanical parts cannot be fixed; when disassembling, the inner hexagonal screw 2 is not easy to be taken out
