[0027] In the present technical solution, the four docking holes 20 are divided into two groups, which respectively fix and limit the two hook structures 18. At the same time, the two docking holes 20 in the same group fix the two docking points of the hook structure 18 to avoid the deviation of the hook structure 18 during operation, causing wear and tear, thereby extending the service life of the transmission part. At the same time, since the two hook structures 18 are fixed, the hook structure 18 is prevented from generating noise during operation.

[0028] As a supplement to the present technical solution, the pedal 1 includes a pedal base 16 and a pedal body 17 , and a pedal rod extending backward is provided at the rear of the pedal body 17 , and the rear end of the pedal rod of the pedal body 17 is connected to the pedal base 16 .

[0029] In the technical solution, a pedal body 17 is provided to facilitate the user to step on it, and a pedal rod is provided to facilitate driving the transmission rod 2.

[0030] As a supplement to the present technical solution, a connecting rod mounting frame 6 is provided on one end where the transmission lever 3 and the upper connecting rod 15 are connected, and a pedal top rod mounting frame 5 is provided on the other end of the transmission lever 3. The connecting rod mounting frame 6 is provided to facilitate the installation of the transmission rod 2, and the pedal top rod mounting frame 5 is provided to facilitate the installation of the pedal top rod 4.

[0031] As a supplement to the present technical solution, a threaded column structure 10 is provided at the upper end of the upper connecting rod 15, and the upper end of the threaded column structure 10 passes through the connecting rod mounting frame 6. A spring adjustment nut 9 is installed at the upper end of the threaded column structure 10, and the lower side is in contact with the connecting rod mounting frame 6. A spring seat 7 is provided at the lower end of the threaded column structure 10, and a return spring 8 is installed between the connecting rod mounting frame 6 and the spring seat 7. The return spring 8 is sleeved and installed on the threaded column structure 10.

[0036] Example

[0037] like Figure 2 As shown, when the position of the upper end of the pedal top rod 4 needs to be adjusted, by rotating the entire height adjustment nut 12, under the action of the height adjustment nut 12 and the height adjustment threaded column 11, the upper end height of the pedal top rod 4 can be adjusted, so that the device can be adjusted according to user needs.

[0038] like Figure 3As shown, the reset speed of the device can be ensured by adjusting the elastic coefficient of the reset spring 8. The reset speed is mainly determined according to the playing habits of the player. The spring adjusting nut 9 rotates, and the spring adjusting nut 9 pushes the reset spring 8 with the connecting rod mounting frame 6, so that the reset spring 8 contracts under the action of the connecting rod mounting frame 6 and the spring seat 7, and its elastic coefficient increases.

[0039] A support is formed between the lower side of the spring seat 7 and the bracket on the piano, so that the lower end of the return spring 8 receives an upward supporting force, so that the return spring 8 can ensure that the transmission lever 3 is reset.

[0040] When operating, the player steps on the pedal 1 with his foot, and the pedal 1 drives the transmission lever 3 through the transmission rod 2, and the transmission lever 3 pushes the pedal top rod 4 to perform a lifting action. After completion, the pedal 1 is released, and under the action of the reset spring 8, the pedal 1, the transmission rod 2 and the transmission lever 3 will return to their original state.
