After the wheel stops rotating, the rotation output member 1 stops rotating, at this time, the locking piece 201 on the first locking member 2 can be completely embedded into one of the locking grooves 101, and the locking concave position 203 on the first locking member 2 is embedded into the locking groove 101, as shown in fig. 9, so that reliable locking is completed.

when unlocking, the motor 6 is controlled to rotate, the second locking piece 3 is driven to swing through the control steel wire 62, the second locking piece 3 drives the first locking piece 2 to swing towards the unlocking direction through the first unlocking structure until the locking piece 201 on the first locking piece 2 completely exits from the locking groove 101, and unlocking is completed;
in the unlocking state, the control block 61 is in an unlocking position under the drive of the motor 6, the position of the second locking piece 3 is fixed through the control steel wire 62, and the unlocking constraint is kept on the first locking piece 2 all the time through the locking protrusion 301 and the locking edge 204, so that the locking piece 201 on the first locking piece 2 is always separated from the locking groove 101 of the rotary output piece 1;
during locking, the control motor 6 reverses, the second locking piece 3 swings back under the action of self elastic hinge, the second locking piece 3 releases the constraint on the first locking piece 2, the first locking piece 2 swings back under the action of self elastic hinge until the locking piece 201 is completely embedded into the locking groove 101, and meanwhile, the second locking piece 3 swings back to be abutted with the first locking piece 2, so that locking is completed.
