Abstract

A lathe wrench with a square column structure, which is composed of an outer sleeve, a stopper pin, a wrench body, a spring, and a plate bar. The lathe wrench with a square structure has a spring, and the spring is set on the cylindrical e part of the wrench body. The square column c and the column e on the wrench body are respectively matched with the round hole d and the square hole a in the middle of the outer sleeve and installed together with the outer sleeve, and the anti-off pin is installed with the upper part of the outer sleeve. At the same time, Make the anti-dropping pin engage in the long groove on the wrench body in the inner part of the outer sleeve, and install the plate bar on the upper end of the wrench body.

Description

technical field [0001] The invention relates to a wrench, in particular to a lathe wrench with a square column structure, belonging to the technical field of hardware tools. Background technique [0002] In the process of using lathe mechanic parts, it is often necessary to use an outer square wrench to loosen or tighten the chuck of the lathe, and an inner square wrench to loosen or tighten the clamping bolts of the lathe tool holder. At present, the wrench used to loosen or tighten the chuck of the lathe and the clamping bolt of the tool holder consists of two sets, which is not only troublesome to use, but also unfavorable for storage. When the personnel is negligent and cannot take off the wrench in time, once the wrench and the chuck rotate together, a major safety accident will occur. Therefore, the existing lathe wrench also has certain potential safety hazards. Contents of the invention [0003] The object of the present invention is to provide a lathe wrench with...
