Abstract

A wrench capable of eliminating torque errors comprises a wrench body, a wrench head is arranged at the front end of the wrench body, a torque adjusting rotary knob is arranged at the rear end of the wrench body, and a covering cap made of wax is arranged on a torque adjusting rotary knob disc in a covering manner, matched with the torque adjusting rotary knob disc in shape and fixed at the rear end of the wrench body via support bolts. The wrench is non-toxic and pollution-free and cannot injury human bodies, and weight and using difficulty of a torque wrench cannot be additionally increased; if torque needs to be adjusted, the support bolts must be unscrewed by a screw driver, mis-touching torque adjustment is avoided, difficulty for operations requiring torque adjustment cannot be increased, and usage is facilitated.

Description

A kind of spanner of eliminating the moment of torsion error

Technical field

The invention belongs to the automobile exhaust system field, relate to the application that a kind of torque wrench is tightened, particularly a kind of spanner of eliminating the moment of torsion error.

Background technology

Torque wrench is used widely in automobile exhaust system, can special requirement be arranged to the moment of torsion of relevant position on the drawing, although same torque wrench examined once surely in 1 year, but the moment of torsion of torque wrench is generally adjustable state in producing at ordinary times, the torque wrench below is for regulating torque knob, when long-time high-frequency was used, this position was easily loosening; In addition, along with for a long time at the scene high-frequency use torque wrench, thereby the operator often has generation touching unintentionally the example that changes moment of torsion by mistake.

Therefore, produce in the product in reality, need a kind of device that can be the torque wrench definite value, solve the problem of above-mentioned existence.

Summary of the invention

Purpose of the present invention provides a kind of spanner of eliminating the moment of torsion error, and this device can be the torque wrench definite value, stops the torque wrench change in torque phenomenon that causes because of operator's maloperation.

The technical scheme that adopts is:

A kind of spanner of eliminating the moment of torsion error comprises wrench body;

The front end of wrench body is provided with driving end, and the rear end of wrench body is provided with the adjusting torque knob, offers display on the wrench body, is known technology;

Buckle closure be located in to be regulated on the torque knob dish, and buckle closure is the wax material, and the shape of buckle closure matches with regulating the torque knob disk shape, and buckle closure is fixed on the wrench body rear end by carrying bolt.

After regulating the even twisting moment knob position, buckle closure is buckled, fix and regulate the torque knob position, in case when high-frequency is used at the scene or operator when being not intended to the carelessness touching and cause the moment of torsion error.

The invention has the advantages that:

Nonpoisonous, non-environmental-pollution of the present invention can not damage human body, can additionally not increase torque wrench weight and use difficulty, as want to regulate moment of torsion, and must use screwdriver to take off support screw, avoided mistake to touch the adjusting moment of torsion, can not regulate to needs simultaneously the operation increase difficulty of moment of torsion, use more convenient.
