At the same time, the outer positioning shaft 22 drives the positioning seat 3 to swing upward. Meanwhile, the inner positioning shaft 21 is just stuck in the second arc groove 32, thus achieving complete unlocking.

[0053] when Figure 7 towards Figure 5 When the state is switched, the spring force of the tension spring 5 mainly keeps the locking part 20 of the locking seat in the center position. Then, under the action of the spring force of the tension spring 5 and the action of the positioning seat 3, the locking part 20 is reset to the first arc groove 31.
