Specifically, the bottom of the pulling piece 33 and the adapter plate 24 are at the same height, and one end of the pulling piece 33, which is close to the adapter plate 24, is designed to be an inclined plane.
As a further explanation of this embodiment, when the adapter plate 24 swings too far to strike the paddle 33, the rotating paddle 33 presses the bottom of the spring plate 31 outward, so that the bottom of the spring plate 31 is separated from the engaging member 32.
The working principle of the utility model is as follows: when the device is used, an external power supply is connected, the motor 22 is started, the rotating disc 24 and the transmission shaft 13 are driven to synchronously rotate through the output shaft, the transmission shaft 13 drives the transmission seat 14, the adapter piece 16, the first top shell 1, the second top shell 3 and the paddles 5 to synchronously rotate while rotating, along with the increase of the service time, when the connection between the rotating disc 24 and the output shaft or the transmission shaft 13 is loose due to arc wear of the first coupler 23 or the second coupler 25, the rotating disc 24 and the transmission shaft 13 swing due to the fact that the eccentricity causes rotation, along with the increase of the swing amplitude, after the protrusions on the side edge of the rotating disc 24 gradually contact the pulling piece 33, the rotating disc 24 drives the pulling piece 33 to start rotating, when the pressure is enough, the top end of the pulling piece 33 outwards jacks up the bottom of the spring plate 31, and enables the bottom of the spring plate 31 to be disconnected with the clamping piece 32, then starts to shrink under the elastic effect of the clamping piece 32, the clamping piece 27 is pushed to be close to the direction of the transmission shaft 13 until the ball shaft plate 28 is tightly attached to the transmission shaft 13, and the ball shaft 28 moves, meanwhile, the first connecting rod 26 and the second connecting rod 29 is driven to be clamped with the end of the second connecting rod 29 is clamped with the end of the eccentric piece, and then the vibration amplitude of the transmission shaft 13 can be fast matched with the transmission shaft 13, and the vibration amplitude is reduced.
The foregoing description is only a preferred embodiment of the present utility model, and is not intended to limit the technical scope of the present utility model, so any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical principles of the present utility model are still within the scope of the technical solutions of the present utility model.
