Abstract

The invention relates to a piano tuning impact wrench. By the piano tuning impact wrench convenient to use, possible damage to peg holes during piano peg tuning can be lowered greatly.

Description

technical field [0001] The invention relates to piano tuning and mechanical tools. Background technique [0002] Adjusting the pegs during piano tuning not only requires a large rotational moment, but also requires precise control of the amount of rotation. Various impact wrenches have been invented to improve efficiency. However, the existing piano tuning impact wrench also has the disadvantage of being inconvenient to use because it does not have an independent operating handle. Contents of the invention [0003] The utility model relates to a piano tuning impact wrench composed of a rotating handle, a rotating body and a transmission shaft. [0004] The invention utilizes the rotating handle to carry out the rotating and impacting operation, which is not only more convenient, but also easier to control the force; since the rotating handle has no specific direction, it is not necessary to select an angle relative to the rotating direction of the piano shaft when it is ...
