Multifunctional tuning hammer for piano

Abstract

The invention relates to the technical field of music equipment, in particular to a multifunctional tuning hammer for a piano, which comprises an outer tube, a movable rod is sleeved in the outer tube, external threads are punched at two ends of the surface of the movable rod, internal threads matched with the external threads are punched at the left side in the outer tube, and a storage groove ispunched at the left side of the movable rod. According to the invention, the movable rod, the U-shaped iron, the concentric-square-shaped hammer, the square hole and the *-shaped hole are arranged, so that the problems that an existing piano tuning hammer is poor in practicability, the angle between a sleeve and a handle cannot be adjusted, the length of the tuning hammer handle cannot be increased, and carrying is inconvenient are solved. According to the multifunctional tuning hammer for the piano, the length of the handle can be adjusted according to the needs of a user, the labor amount is reduced, the concentric-square-shaped hammer is provided with two types of sleeves at the same time, the hammer is suitable for all piano string winding rods at present, the practicability of the tuning hammer is improved, and the hammer is more convenient to carry by the user after being stored.

Description

technical field [0001] The invention relates to the technical field of musical instruments, in particular to a multifunctional tuning hammer for a piano. Background technique [0002] The tuning hammer is like a general small hammer, also known as a tuning wrench, which is a tool for tuning the piano, because the principle of piano sound is to adjust the vibration frequency of the strings through the hammer to make the strings emit different tones, so There is a tuning hammer, the standard vibration frequency of the piano is 440 Hz, and the standard tone is 6 in a group of small characters.
