Fine adjustment device

Abstract

The invention relates to a fine adjustment device. The fine adjustment device comprises a shell and a handle, a sleeve integrally formed with the shell is arranged on one side of the shell; an openingof the sleeve is rotatably provided with a connecting pipe, one end of the connecting pipe is provided with the handle, the other end of the connecting pipe is provided with a transmission rod extending into the sleeve and the shell, and the shell far away from one end of the handle is provided with a supporting mechanism for supporting the transmission rod. The fine adjustment device has the advantages that the problems in the prior art are solved; the current situation of tuning peg fine adjustment is changed, the way of transmitting torque through manual force is changed into the way of transmitting torque through rotation movement by manual acting on the handle, and the fine adjustment deivce has the advantages of being convenient and reliable to operate, accurate in tuning and capable of guaranteeing piano peg safety, achieves the purpose of manual steel wire fine adjustment, effectively solves the problem of steel wire fine adjustment, and is wide in application range, convenient to operate and suitable for people of all ages.

Description

technical field [0001] The invention relates to a fine-tuning device, which is mainly used for the fine-tuning of musical instruments with pegs. Background technique [0002] Taking the piano as an example, the tuning of the piano is actually to use tools to tighten the pegs of the piano. When the piano pegs are tightly wound and then tuned, it is difficult to fine-tune. The existing piano tuning tools on the market all use single-axis manual force to transmit torque, especially when fine-tuning, the amount of force is difficult to control, relying on feeling to adjust, sometimes the steel wire will be broken, directly affecting the tuning At the same time, as the tuners grow older, the control of the piano tuning becomes a difficult problem. Many tuners can no longer adjust the temperament because of their age and force problems. Contents of the invention [0003] For overcoming the defective of prior art, the present invention provides a kind of fine-tuning device, tech...
