Description

A type of bolt percussion wrench with adjustable opening size

technical field

The utility model relates to the technical field of mechanical processing, in particular to a bolt percussion wrench with an adjustable opening size.

Background technique

A wrench is a common installation and removal tool, usually made of carbon or alloy structural steel. A wrench is a hand tool that uses the principle of leverage to turn bolts, screws, nuts or other threaded fasteners. The wrench is usually provided with jaws or sleeves at one or both ends of the handle for clamping the bolt or nut. The bolt or nut can be turned by applying an external force on the shank in the direction of thread rotation; in equipment, machinery, petrochemical and other places, bolts are often used as connecting parts of various components, and the bolts used are usually larger. Because larger bolts are not easy to disassemble, and the bolts usually corrode after long-term use, the commonly used wrench is a percussion wrench when removing bolts. Due to the heavy weight of the percussion wrench itself, it is difficult for the operator to disassemble the bolt by twisting its handle when in use, so it is necessary to knock the handle with a blunt object such as a hammer to disassemble the bolt;

However, the size of the jaw ring of the existing percussion wrench is inconvenient to fix, and in actual use, the types of bolts to be removed are different, so different types of jaw rings are required for removal, which is not only inconvenient to carry, but also very wasteful cost.
