Technical Field
[0001] The utility model relates to the technical field of piano practice, in particular to a hand shape corrector for piano practice. Background Art
[0002] The piano is a keyboard instrument in Western classical music and is known as the "king of instruments". When learning the piano, the correct posture is the basis for playing beautiful music. Beginners are very likely to make hand shape mistakes when learning the piano, especially the posture of the wrist. Especially for younger students, it is very difficult to lift the end joints of the fingers. Over time, a bad piano-playing habit is formed, which greatly hinders the improvement of the playing level. If beginners do not grasp the correct wrist posture, the initially correct playing hand shape will gradually become uncontrollable, and ultimately lead to hand shape variation during playing, which not only easily causes rapid finger fatigue, but also more easily causes finger injuries.
[0003] Currently, there are two types of finger correction trainers for piano playing on the market, both of which are for correcting the collapse of the metacarpophalangeal joints of piano players. One is that the player places the five fingers on the trainer, and each of the five fingers has a fixed placement point. There is a support ball near the wrist that can be adjusted in height to prevent the player's wrist from being too low. The purpose is to train the finger strength and hand shape of the player. The other is to fix it on the player's wrist with a strap, so that the support ball is located at the metacarpophalangeal joint position that needs to be trained for support, so as to achieve the purpose of preventing the metacarpophalangeal joint from collapsing during playing.
[0004] The above two corrections have some drawbacks: First, the trainer does not have a size adjustment function. The age range of piano players spans from kindergarten children to elderly friends, and their palm sizes are different. If there is only one fixed size, it will be difficult for players to fully apply the trainer, and the training effect is not ideal. Second, although there is a support ball near the wrist part of the trainer, and this support ball can be adjusted in height according to needs, it doesn't make much sense. Since the support position is too close to the wrist and the ball is too large, it may cause the metacarpophalangeal joint to be too low during training, and still form the problem of metacarpophalangeal joint collapse. In fact, it doesn't really solve the hand shape problem of the player. Third, the positions for placing the five fingers are flat, which easily causes the first joint of the player to collapse. Fourth, in order to fix the support ball, the support ball is tied to the player's arm with a strap. This will cause the player's hand to be not flexible enough during playing, and the wrist movement is restricted, which is not very friendly to playing "falling and lifting" or large-span chords. When playing "falling and lifting", it is required that the wrist move up and down flexibly enough. When playing large-span chords, the hand shape will change, and the support ball will form a certain obstructive effect. Content of the Utility Model
[0005] The purpose of the present utility model is to solve the problems in the prior art that after long-term dyeing operations, dyes will precipitate and it is impossible to scrape off the excess dyes on fabrics of different thicknesses, and to propose a hand shape corrector for piano practice.

[0014] Compared with the prior art, the present utility model provides a hand shape corrector for piano practice, which has the following beneficial effects.
[0015] 1. This solution can adjust the positions of the five correctors simultaneously, so that it can not only adapt to players of different ages, but also ensure that the positions of the five fingers of the player are always in the correct arrangement when the five correctors are adjusted together. If each corrector is adjusted separately, it may lead to an incorrect adjustment angle of a certain corrector, resulting in an incorrect arrangement order of the five fingers and a deformed hand shape.
[0016] 2. By placing the support ball at the position facing the metacarpophalangeal joint of the middle finger and adjusting it up and down, this solution can greatly improve the problem of the collapse of the metacarpophalangeal joint of the player. By inserting the player's finger into the inner part of the finger groove, it can effectively prevent the collapse of the first joint of the player's finger. BRIEF DESCRIPTION OF THE DRAWINGS
