Two groups of notch grooves are symmetrically arranged on the upper part of the fork shaft 6, and the positions of the two groups of notch grooves correspond to the positions of the two groups of fork pins 3. When the movable seat 4 reciprocates back and forth outside the two groups of guide rods 7 through the two groups of sliding sleeves 8, the fork shaft 6 is in a following moving state. Then, the two groups of fork pins 3 intercept the fork shaft 6.
