Under the premise that the horizontal height of the positioning member 3 is relatively fixed, the inner cylinder 8 is influenced by the elastic force of the return spring 7 and moves downwards, and the positioning member 3 and the inner cylinder 3 have the following two position relations according to the stop position relation of the displacement boss 31:

long matching state: when the displacement boss positioning member 31 is located at the non-use position 31T, the distance between the head and the tail of the positioning member 3 and the inner cylinder 3 is maximized.

Short matching state: when the displacement boss positioning member 31 is located at the use position 31P, the distance between the positioning member 3 and the inner cylinder 3 is minimized.

The above-described switching of the long engagement state to the short engagement state is performed by using the switching slope 221 and the fall-back switching slope 231. And the switching from the short engagement state to the long engagement state is performed by the reset switching slope 223 and the reset long slope 233.

The error value of the angle is preferably controlled within 15 °.

A long matching straight groove 235 is also arranged between the reset long slope 233 and the long limit platform 234.

The use switching slope 221 is completely covered above the non-use place 31T. On the premise of not influencing the displacement boss positioning piece 31 to pass through the resetting long slope 233, the reciprocating long slope 223 continues to extend for a certain distance.
