In addition, the above-mentioned pressing and twisting mechanism may further include a pressing and twisting reset structure 500 provided at an end of the pressing and twisting block structure 200, and the pushing structure 300 corresponds to the pressing and twisting reset structure 500. In the process of pushing the knob body 210 of the knob structure 200 by the pushing structure 300, not only the knob body 210 is linearly moved, but also the knob return structure 500 is compressed, and when the pushing structure 300 is not pushed any more, the knob return structure 500 returns the knob structure 200 to the original position by the reaction force of the knob return structure 500.
Specifically, the torsion block 210 may further include a torsion cylinder 214 protruding from an end of the torsion main block 212 and extending out of the guide rail cylinder 100, and the pushing structure 300 is connected to an end of the torsion cylinder 214. By arranging the torque pressing barrel 214 at the end of the torque pressing block body 210, not only the connection with the pushing structure 300 but also the arrangement of the torque pressing reset structure 500 on the torque pressing barrel 214 are facilitated. Moreover, the above-mentioned pressure-torsion reset structure 500 may include a first pressure-torsion reset baffle 510 movably sleeved on one end of the pressure-torsion cylinder 214 and fixedly clamped on the end of the guide rail cylinder 100, a second pressure-torsion reset baffle 520 fixedly sleeved on the other end of the pressure-torsion cylinder 214, and a pressure-torsion reset spring 530 sleeved on the pressure-torsion cylinder 214 and located between the first pressure-torsion reset baffle 510 and the second pressure-torsion reset baffle 520. Thus, when the pushing structure 300 pushes the pressure-torsion cylinder 214, the pressure-torsion cylinder 214 drives the pressure-torsion main block 212 to move linearly towards the inner side of the guide rail cylinder 100, at this time, the first pressure-torsion return baffle 510 is fixedly clamped on the guide rail cylinder 100 and cannot move along with the pressure-torsion cylinder 214, and the second pressure-torsion return baffle 520 fixedly sleeved on the pressure-torsion cylinder 214 moves along with the pressure-torsion cylinder 214, so that the pressure-torsion return spring 530 between the two is compressed, and when the pushing structure 300 and the pressure-torsion block 210 are not applied with pushing force, the second pressure-torsion return baffle 520 and the pressure-torsion cylinder 214 automatically return under the elastic force of the pressure-torsion return spring 530, so that the pressure-torsion block 210 and the rotation shaft automatically return.

Moreover, the rotating shaft structure 400 may further include a rotating shaft resetting structure 600 disposed on the rotating shaft head 420, and the rotating shaft resetting structure 600 is located in the cavity of the pressure-torsion cylinder 214. As can be seen from the above, in the process of pushing the torsion block 210 to move linearly by the pushing structure 300, the torsion block 210 rotates under the guidance of the guide groove 112 of the guide cylinder 100, and the rotating shaft not only rotates along with the torsion block 210, but also moves linearly in the limit groove 2124 of the torsion main block 212, so that the rotating shaft is displaced in the axial direction. By providing the spindle restoring structure 600 on the spindle head 420 of the spindle body, the spindle body can be restored to the original position when no longer being acted by the pushing structure 300.
Further, the shaft resetting structure 600 may include a first shaft resetting baffle 610 movably sleeved on one side of the shaft head 420 and fixed on the inner wall of the pressure torsion cylinder 214, a second shaft resetting baffle 620 fixedly sleeved on the other end of the shaft head 420, and a shaft resetting spring 630 sleeved on the shaft head 420 and located on the first shaft resetting baffle 610 and the second shaft resetting baffle 620.
