Novel spanner

Abstract

The invention relates to assembly manual tools used by bench workers, in particular to a novel spanner. The novel spanner can stretch and retract freely and be adapted to different work environments. The novel spanner comprises a jaw and a handle. The outer side of the handle is provided with threads and connected with a telescopic handle through the threads. The length of the handle is matched with that of a cavity inside the telescopic handle. A leather sleeve is arranged on the outer side face of the telescopic handle. A temperature inductor is further arranged outside the jaw.

Description

technical field [0001] The invention relates to fitter and assembly hand tools, in particular to a new type of wrench. Background technique [0002] As we all know, a wrench is a tool for turning bolts, nuts and other objects that are difficult to turn by hand, and is widely used in fitters and mechanical manual assembly processes; existing wrenches generally include jaws and handles, and the jaws are stuck After the object, use the lever principle to hold the handle and tighten or loosen the object. During the use of this wrench, if you encounter very tight bolts or nuts that need to be loosened, or you need to tighten the bolts or nuts to very In tight conditions, the handle is not long enough and the required force arm is not enough, or when the assembly space is narrow, the handle is too short and it is difficult to extend the wrench to the assembly position.

[0002] As we all know, a wrench is a tool for turning bolts, nuts and other objects that are difficult to turn by hand, and is widely used in fitters and mechanical manual assembly processes; existing wrenches generally include jaws and handles, and the jaws are stuck After the object, use the lever principle to hold the handle and tighten or loosen the object. During the use of this wrench, if you encounter very tight bolts or nuts that need to be loosened, or you need to tighten the bolts or nuts to very In tight conditions, the handle is not long enough and the required force arm is not enough, or when the assembly space is narrow, the handle is too short and it is difficult to extend the wrench to the assembly position. In addition, the wrench is in the During use, you will face complex ambient temperature or mechanical working temperature. If you ignore the detection, it may cause burns and other human damage.
