When the upper spring cylinder 91 and the lower spring cylinder 9 are disassembled, the vane type piston assembly rotating shaft is connected with the rotating shaft 3, then the bolts between the upper spring cylinder 91 and the lower spring cylinder 9 are removed, then the rotating shaft 3 drives the vane type piston assembly and the worm spring to rotate, so as to avoid the rebound of the worm spring caused by the removal of the bolts to cause safety accidents.

[0030] Referring to Figure 1 and Figure 2The driving motor 4 is connected with a worm 5, the worm 5 is rotatably connected with the rack 1, the worm 5 is engaged with a worm wheel 51, and the worm wheel 51 is connected with the rotating shaft 3.

A reversing wheel 11 is arranged above the rack 1, one end of the rotating shaft 3 is fixedly connected with a steel wire 31, the steel wire 31 passes through the reversing wheel 11, and one end of the steel wire 31 away from the rotating shaft 3 is connected with a counterweight 32. The counterweight 32 has the same weight as the rotating shaft 3, so that the operator only needs to lift the counterweight 32 to make the rotating shaft 3 slide downward in the through hole 511. The worm spring requires a large torque for deformation, and the transmission of the worm 5 and the worm wheel 51 can reduce the output torque required by the driving motor 4, so that the driving motor 4 can more smoothly drive the rotating shaft 3 to rotate, and the worm wheel 51 and the worm 5 have a self-locking function to prevent the rotating shaft 3 from rotating.

The slider 23 is provided with teeth that mesh with the tooth on the side near the transmission disc 22, so that when the transmission disc 22 rotates, the slider 23 is driven to slide along the chute grooves 212. The slider 23 is fixedly connected to a clamping block 231 for clamping the spring lower cylinder. There are four chute grooves 212, four sliders 23 and four clamping blocks 231, and the four clamping blocks 231 are arranged in a circular array.
