By providing the rail roller 224 at the end of the rail shaft body 222, the rail roller 224 can slide along the rail groove 112, so that the rail shaft body 222 and the torsion block body 210 can stably slide along the rail groove 112. In addition, the guide rail roller 224 can be embedded in the guide rail groove 112, and the guide rail roller 224 can freely slide along the guide rail groove 112, so that the guide rail roller 224 and the guide rail shaft body 222 can be limited in the guide rail groove 112, and the sliding and rotating of the torsion block body 210 are more stable and reliable.
The main compression-torsion block 212 may be a flat block, and the inner cavity of the guide rail cylinder 100 may be a flat cavity, in which the main compression-torsion block 212 is disposed.

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.
