A part of the ball 200 protrudes from the first clutch surface 101. The ball 200 can rotate relative to the first clutch surface 101 when subjected to external force. The second drive group 300 is provided with a second clutch surface 310, and a plurality of recessed positions 311 are provided on the second surface, and the recessed positions 311 are distributed around the center of the second clutch surface 310, and the recessed positions 311 can be arranged to be distributed in sequence with equal spacing. The shape of the recessed position 311 is set to be a spherical concave shape. The second drive group 300 can rotate around its own rotation axis, and the center of the second clutch surface 310 is on the rotation axis of the second drive group 300. The first clutch surface 101 and the second clutch surface 310 face each other, and the first clutch surface 101 and the second clutch surface 310 are coaxially arranged. The number of recessed positions 311 can be the same as the number of balls 200, or the number of recessed positions 311 can be more than the number of balls 200. The beads of each ball 200 protruding from the first clutch surface 101 are matched one by one and abutted in the recessed positions 311. The elastic component 400 can apply an elastic force to the first drive group 100 and / or the second drive group 300, and the elastic force drives the first clutch surface 101 and the second clutch surface 310 to approach each other. In actual use, one of the first drive group 100 and the second drive group 300 is used as a power input group, and the other is used as a power output group.

When the second drive group 300 rotates, the recessed position 311 and the ball 200 are used to transmit to the first drive group 100, so that the first drive group 100 and the second drive group 300 rotate synchronously and coaxially. The first drive group 100 is connected to the cover plate or seat ring of the smart cover plate or smart toilet, driving the cover plate or seat ring to flip.When the first drive group 100 and the second drive group 300 drive the cover plate to flip in a certain direction, if the user forcibly rotates the cover plate in the opposite direction, at this time, the first drive group 100 rotates relative to the second drive group 300 in the opposite direction, the ball 200 slides out of the current recess 311, the ball 200 abuts on the surface of the non-recess 311 on the second clutch surface 310, the distance between the first clutch surface 101 and the second clutch surface 310 becomes larger, the elastic component 400 is elastically compressed, and as the first drive group 100 rotates, the ball 200 slides into the next recess 311, so as to achieve the purpose of clutch. The overall structure is simple.
