Abstract

The invention belongs to the technical field of tightening devices, and particularly relates to a multi-specification fastener tightening device with a simple structure. The following scheme is provided currently in order to solve the problems of inconvenience in use, incapability of tightening hexagon socket screws and relatively small application range of an existing monkey wrench for bolts withdifferent sizes, the multi-specification fastener tightening device comprises a disc, a plurality of polygonal rods are connected to the bottom of the disc, a circular plate is fixedly connected to the top of the disc, a circular groove is formed in the top of the circular plate, a circular block is rotationally installed in the circular groove, a plurality of clamping grooves are evenly formed in the outer side of the circular block, a circular hole is formed in the inner wall of the circular groove, a circular rod is rotationally installed in the circular hole, and an elastic groove is formed in one end of the circular rod; and a clamping block is slidably installed in the elastic groove, a bevel edge is arranged on one side of the clamping block, and the same spring is fixedly installed between the clamping block and the elastic groove. The device is simple in structure and convenient to operate, and can be used for the bolts with different sizes and specifications, and the application range is widened.

Description

technical field [0001] The invention relates to the technical field of tightening devices, in particular to a multi-standard fastener tightening device with simple structure. Background technique [0002] In the processing and maintenance of machinery, workpieces, etc., it is often necessary to tighten bolts, etc., and the common tool for tightening bolts is a wrench. Because the specifications and sizes of bolts are different, the corresponding wrenches used are also different. [0003] Existing adjustable wrenches are available for bolts of different sizes, but the adjustable wrench is inconvenient to use and cannot tighten the inner angle bolts, so the scope of application is small. Contents of the invention [0004] The purpose of the present invention is to solve the existing adjustable wrench for bolts of different sizes, but the adjustable wrench is inconvenient to use, and cannot tighten the inner angle bolts, and has a small application range. Specification faste...
