Wherein in the cylinder body, the cavity with the piston rod on one side of the piston is a rod cavity 5-2, the other side of the piston is a rodless cavity 5-1, gas is introduced into the rodless cavity 5-1, the piston rod can be extended, so that the advance of the platform 2 is realized, and gas is introduced into the rod cavity 5-2, the piston rod can be retracted, so that the retreat of the platform 2 is realized.

[0027] The rodless cavity 5-1 of the cylinder 5 is connected with a gas source through a rodless cavity gas supply pipeline 6, and the rodless cavity gas supply pipeline 6 supplies gas to the rodless cavity 5-1.

[0028]

[0029] ​The rod cavity 5-2 of the cylinder 5 is connected with the gas source through the rod cavity gas supply pipeline 7, and is supplied with gas through the rod cavity gas supply pipeline 7.

[0030] The rod cavity gas supply pipeline 6 and the rod cavity gas supply pipeline 7 are connected with the reversing valve, and are connected with the gas source through the reversing valve.

[0031] The reversing valve adopts a three-position four-way electromagnetic valve 8, which includes a forward position, a neutral position and a backward position.
