Spring compensation structure for a torque wrench

摘要

A spring compensation structure for a torque wrench includes a body, a compensation component and an engaging head. The body has a first connecting portion, The compensation component is installed on the body and has a compensation distance, wherein one end of the compensation component is abutted on the first connecting portion of the body. The engaging head has a second connecting portion; the second connecting portion is detachably disposed on the body and is abutted on the other end of the compensation component, wherein a distance between the second connecting portion and the first connecting portion is equal to the compensation distance.

1. A spring compensation structure for a torque wrench, the spring compensation structure comprising:
a body having a first connecting portion; a compensation component installed on the body and having a compensation distance, wherein one end of the compensation component is abutted on the first connecting portion of the body; and an engaging head having a second connecting portion, the second connecting portion being detachably disposed on the body and being abutted on an other end of the compensation component, wherein a distance between the second connecting portion and the first connecting portion is equal to the compensation distance; wherein the compensation component is adjustably formed by stacking a plurality of different compensation units, each of the compensation units having a compensation unit distance, a sum of the compensation unit distances is equal to the compensation distance, and the compensation distance is adjustable through replacing the compensation units to new compensation units having new compensation unit distances; wherein a torque loss caused by elastic fatigue of a spring of the torque wrench is compensated by adjusting the compensation distance.
