At this time, the n-shaped push rod 205 drives the second L-shaped slide rod 5 to move upward, and the first convex column 505 drives the one-way bearing 504 to rotate clockwise by the first threaded sliding slot 501, because of the one-way transmissibility of the one-way bearing 504, the inner ring of the one-way bearing 504 idles and does not drive the third spur gear 503 to rotate.

With the twisting of the lower part of the guide tube 207, the guide tube 207 rotates clockwise through the third fixing rod 604, the sliding block 606 and the L-shaped guide rod 608, and is acted by the guide chute 601, with the clockwise rotation of the L-shaped guide rod 608, the L-shaped guide rod 608 drives the sixth fixing block 609 and the parts thereon to move outwards through the sliding block 606, the outward movement of the sliding block 606 compresses the second spring 607, then under the action of the L-shaped fixing rod 605, the seventh fixing block 610 rotates towards the adjacent sixth fixing block 609, and makes the first torsion spring 611 generate torsional force, while the seventh fixing block 610 moves to make the arc column 612 extend into the chute of the sixth fixing block 609, with the entry of the arc column 612, the arc column 612 will press the L-shaped slide rod 613 to move, the L-shaped slide rod 613 will compress the third spring 614, after the arc column 612 fully extends, under the action of the third spring 614, the L-shaped slide rod 613 will move into the groove of the arc column 612, the L-shaped sliding rod 613 limits the arc-shaped column 612, at this time, the sixth fixed block 609 and the seventh fixed block 610 are fixed together, the sixth fixed block 609 is opened to release the limitation on the lower end of the guide tube 207, simultaneously, the L-shaped guide rod 608 contacts with the first sliding column 602 along with the rotation of the L-shaped guide rod 608, the L-shaped guide rod 608 presses the first sliding column 602 to move and compress the first spring 603 due to the inclined surface of the first sliding column 602, and after the L-shaped guide rod 608 passes through the first sliding column 602, the first sliding column 602 is popped up under the action of the first spring 603 to limit the L-shaped guide rod 608.
