Firstly, the deflection frame 4 is in an initial position, the deflection angle is parallel to the angle of the sliding groove on the sliding groove ring 1, namely, a sliding block which is about to enter the sliding groove enters the same sliding groove where the previous sliding block in the sliding groove is located, the moving direction of the sliding block is parallel to the angle of the sliding groove, at the moment, no force acts on the sliding groove, the sliding groove ring 1 does not rotate, and the sliding rod ring 3 idles, which is equivalent to a neutral gear.
Secondly, the deflection frame 4 deflects to the left to the position of an angle a1, the deflection angle is smaller than the parallel angle of the sliding grooves on the sliding groove ring 1, a sliding block which is about to enter the sliding groove enters the first sliding groove which is adjacent to the left of the sliding groove where the previous sliding block in the sliding groove is located, and the sliding block extrudes the surface on the right of the sliding groove when continuing to move forwards, so that the sliding groove ring 1 is driven to rotate clockwise, which is equivalent to reverse gear.
