In this step, the second spring 370 is continuously largely deformed, the third push block 360 slides from the left portion to the right portion of the strip-shaped hole 313, and the guide rod 340 sequentially passes through the third push block 360 and the limit baffle 380 from right to left.

And fifthly, resetting each part.

To sum up, the utility model discloses an foretell structural design solves the weak point that exists among the prior art, has characteristics such as structural design is reasonable, excellent in use effect.
