The friction force between the ball and the track enables the ball to roll in the track, sliding friction is changed into rolling friction, the friction force between the sliding body and the track is reduced, the resistance of the sliding body in the track is reduced, the sliding body can smoothly slide in the track under the action of radial component force given to the sliding body by the track, and stable sliding of the shell in the track can be guaranteed.

Further, the one-way driving piece comprises an inclined plate fixedly connected to the inner side wall of the track, and the inclined plate is made of elastic materials. When the sliding body slides in the track, the sliding body moves to the free end of the inclined plate from the joint of the inclined plate and the track, the inclined plate is extruded by the sliding body, and the inclined plate cannot block the movement of the sliding body.

Further, the swash plate is located the boss of track. When the sliding body moves from the concave part to the convex part and reaches the convex part, the inclined plate can ensure that the sliding body can cross the convex part, and when the sliding body crosses the convex part to move towards the concave part, the sliding body can return to the initial position from the convex part through the inertia of the sliding body, so that the sliding body can be ensured to slide in the track in one way only by arranging the inclined plate at the convex part of the track.
