[0017] Preferably, the surface of the abutting block is sleeved with a rubber sleeve, and the rubber sleeve is in a circular arc shape.

[0018] The effect achieved by the above components is that the rubber sleeve is arranged in a circular arc shape, which protects the piezoelectric ceramic sheet, avoids damage to the piezoelectric ceramic sheet caused by the abutting block repeatedly contacting the piezoelectric ceramic sheet, and improves the practicability of the device.

[0019] Preferably, the first hinge and the second hinge are both made of insulating metal.
