The conical gear disc 9 drives the conical gear 7 and the gear 5 meshing with the conical gear 7 to rotate synchronously. The gear 5 drives the adjusting component 4 to rotate. When the knocking piece 43 rotates, it continuously knocks the bottom of the contact strip 36 to generate shaking. Since the device is provided with multiple groups, multiple groups of experimental objects can be simultaneously tested synchronously.

[0029] During the process, when the electric telescopic rod 45 pushes the disc 441 and the connecting disc 42 to move and adjust the horizontal position, the position where the knocking piece 43 knocks the contact strip 36 changes.
