Abstract

The invention belongs to the technical field of piano exercise assisting equipment, and specifically relates to a hand gesture correcting device for assisting the piano practice. The correcting devicecomprises a hand holder and a fixed frame. The hand holder is installed on the fixed frame, and the fixed frame comprises two vertical fixed rods, an avoiding support rod, and a sliding rail. The upper end of the avoiding support rod is provided with a sliding rail installation seat, and the sliding sleeve is disposed above the sliding rail installation seat. The sliding sleeve is disposed underthe hand holder. Two vertical fixed rods are connected through a positioning adjustment rod and a reinforcing rod. Lower support legs are disposed under the vertical fixed rods, and rollers are disposed under the lower support legs, and can draw back into the lower support legs. The hand holder of the correcting device can flexibly move at a long distance, and meets the gesture correcting demandsof the persons during piano practice. In addition, the height of the hand holder in the correcting device and the width of the correcting device can be adjusted, thereby enabling the correcting deviceto meet the application demands of pianos in different sizes. Moreover, the correcting device cannot cause the wear of the piano in an application process, thereby facilitating the protection of thepiano.

Description

technical field [0001] The invention belongs to the technical field of piano auxiliary practice equipment, in particular to a hand shape corrector for assisting piano practice.

Problems solved by technology

At present, the more common hand orthotics include two clips that can be stuck on the piano and a cross bar above the clips. A hand rest is set on the cross bar. The disadvantage of this orthosis is that the guide rail is fixed and the hand rest moves The range is limited, that is, when people use this kind of corrector, they can only correct the hand shape in the front of the body, and for a wider range, people don't need to use the corrector to correct

This makes the corrective effect of existing aligners less effective

In addition, the existing straighteners need to be stuck on the piano. Usually, the piano is beautifully made and expensive. Frequent use of the existing straighteners will cause wear and tear on the piano body and affect the overall appearance of the piano.

In addition, the size of the piano is different, and the existing corrector cannot be adjusted according to the piano of different sizes, which limits the scope of application of the corrector
