Abstract

The invention discloses a piano tuning tool, and belongs to the field of musical instrument making. The piano tuning tool has such characteristics as being time-saving and labor-saving, simple and convenient to operate, and easy to master. On the basis of a screw propelling principle, a multi-start thread is adopted and a screw sleeves inside a nut; the multi-start thread, which is relatively high in lead angle, relatively low in friction force and easy to slip, is favorable for force transmission and motion. Depending on the principle, a regulating screw is designed as a going-through shaft which sleeves inside a locating nut; a circular shaft above the regulating screw is embedded in a spherical round hole of a tuning spanner; an octagonal inner hole below the regulating screw sleeves a tuning piano column; a U-shaped fork on one side of the locating nut is clamped and located on an adjacent piano shaft. Therefore, the tuning spanner can be pulled through relatively small force, and then the regulating screw is driven to do uniform motion in the locating nut, thus tuning a piano.

Description

[0001] Original technical field [0002] The patent of the present invention relates to the field of musical instrument manufacturing, and is a piano tuning tool, called a piano tuning tool. Background technique [0003] At present, the tuning of the piano is mainly manually operated by the tuning wrench, and it is difficult to control the strength, especially when the fine-tuning is high and low, which brings great inconvenience to the tuning work. Contents of the invention [0004] In order to solve the problems in the "background technology", the piano tuning treasure provided by the patent of the present invention has the characteristics of convenience, quickness, time-saving and labor-saving, and easy control, which provides great convenience for piano tuning and solves the problem of Difficulties that exist when fine-tuning a piano. [0005] The technical solution adopted by the technical problem solved by the patent of the present invention is: adopt the principle of...
