Problems solved by technology

[0003] The tuning tool only has a tuning wrench. The tuning wrench is a special tool for turning the pin of the piano peg to adjust the size of the string tension and to raise or lower the sound. The shape of the existing piano tuning wrench is changed after leaving the factory. fixed, causing people to not be able to adjust the angle and length of the wrench according to the actual situation when using it, making it difficult to adjust the wrench to a smooth state and affecting people's adjustment efficiency. Therefore, in view of the above status quo, it is urgent to develop a piano tuning law wrench to overcome the deficiencies in current practical applications

Abstract

The invention relates to the technical field of piano tuning tools, in particular to a piano tuning wrench which comprises an adjusting rod, a fixing rod is fixedly connected to one side of the adjusting rod, a connecting block is rotatably connected to the outer side of the end, away from the adjusting rod, of the fixing rod, a wrench head is in threaded connection with the connecting block, the connecting block is connected with the adjusting rod through an adjusting mechanism, and the other end of the adjusting rod is connected to a telescopic mechanism. The angle of the wrench head can be adjusted by arranging the adjusting mechanism, people can use the wrench more conveniently, the clamping mechanism is arranged, a piston is pushed through air pressure, a clamping block arranged on the piston clamps a rotating rod, and therefore the fixing of the connecting block is achieved; the stability of the device in using is ensured, by arranging the telescopic mechanism, a motor is used for driving a threaded rod to rotate, the distance between a sleeve and a supporting rod can be adjusted through the action of the threaded rod and a limiting rod, and therefore the length of the device is adjusted, and the comfort of the device in use is enhanced.

Description

technical field [0001] The invention relates to the technical field of piano tuning tools, in particular to a piano tuning wrench. Background technique [0002] Piano tuning is to tighten or loosen the strings to make them reach a certain pitch, that is, a group of a sounds in small characters, the vibration frequency is 440Hz as the standard, and each note of the piano is adjusted according to the method of twelve equal temperaments. , Piano tuning is a more complicated job. Tuning lawyers must not only adjust the tone, but also adjust the mechanical parts of the piano to normal, so that each system can return to normal, so that the good performance and musical effects of the piano can be fully utilized. [0003] The tuning tool has only a tuning wrench, and the tuning wrench is a special tool for turning the pin of the piano peg to adjust the tension of the strings and to raise or lower the sound. The shape of the existing piano tuning wrench is changed after leaving the f...
