The application form of the installation device is as follows: the mounting seat can be provided with the key, the string pressing block, the reset element and other elements required by the string pressing device of the stringed instrument; the prior auxiliary string pressing device of the stringed instrument can also be directly arranged on the mounting seat.

Stringed musical instruments to which the mounting device is adapted include, but are not limited to, guitars, ukraini, and the like. The structure of the auxiliary string pressing device of the stringed instrument will be described by taking a guitar as an example and combining with a mounting device. The string pressing assisting device for the stringed instrument comprises a key 6, a string pressing block 7 and a reset element 8, wherein the key 6 is arranged on the upper part, the string pressing block 7 is arranged on the lower part, and the reset element 8 can reset the string pressing block.

The reduction element 8 has two forms.

The first method comprises the following steps: the reset element is an elastic sheet 8.

As shown in fig. 7 to 14, the elastic sheet 8 includes a fixed end fixed to the longitudinal plate 12 and a free end facing the neck fingerboard, the key 6 is located at the upper end of the free end, and the string pressing block 7 is located at the lower end of the free end. The player presses the key 6 with the fingers, the elastic sheet 8 moves downwards, the string pressing block 7 touches and presses the string 51, the player separates the keys 6 with the fingers, the elastic sheet 8 resets, and the string pressing block 7 is far away from the string 51. The positions of the string pressing blocks 7 are set according to the size of the frets 53 (the distance between the frets 52 and 52) and the distance between the strings 51 and 51, so that the aim of playing more crisp is fulfilled.

In one embodiment, the number of the elastic pieces 8 is at least one, and when there are a plurality of elastic pieces 8, the elastic pieces 8 are arranged in parallel, and the elastic pieces 8 have a space therebetween. The number of the elastic pieces 8 is not limited. The arrangement of the elastic pieces 8 is not limited to the parallel, as long as the keys 6 are pressed, and the string pressing blocks 7 can contact the strings 51. The spacing between the resilient tabs 8 varies. In this embodiment, the elastic piece 8 is parallel to the horizontal plate 11. As a specific example, the elastic sheet 8 has a certain length. This ensures a certain pressing amplitude of the elastic piece 8. The elastic pieces 8 are different in length, some elastic pieces 8 are I-shaped, and some elastic pieces 8 are L-shaped. The resilient tabs 8 are arranged in a rational manner so that the limited space in the frame can be used in a rational manner.

In some embodiments, as shown in FIG. 9, the keys 6 correspond up and down, or are staggered, with respect to the chord pressing block 7. That is, the key 6 may be located at any position on the free end, but it is desirable to contact the string 51 when pressed, and to press it with less effort, so that the key 6 and the key 6 do not interfere with each other and affect each other. In some embodiments, the pressing string piece 7 is located at the end of the free end 82 of the elastic piece, or anywhere on the free end 82. The string pressing block 7 may be located at any position on the free end 82, at the end of the free end 82, near the end, or in an intermediate position, etc. In some embodiments, a plurality of pressing blocks 7 are provided at the free end 82 of the same elastic sheet 8. A plurality of string pressing blocks 7 can be arranged on the same elastic sheet 8, as shown in fig. 9, so that when one key 6 on the elastic sheet 8 is pressed down, the plurality of string pressing blocks 7 move downwards simultaneously, a plurality of strings 51 can be touched and pressed simultaneously, the learning of a beginner is facilitated, the tension and the pressure of the beginner are improved, and the player can play well even if the player is separated from an auxiliary device. Of course, the pressing blocks 7 on the same elastic sheet 8 do not press the same string 51. As a specific example, the string-pressing block 7 spans two strings 51, as shown in FIG. 9. Some of the string pressing blocks 7 may be arranged to span the lengths of the two strings 51 so that the strings 51 can be simultaneously touched when the string pressing blocks 7 spanning the lengths of the two strings are pressed.
