The lifting rod 3 is a threaded rod and is driven by a lifting motor 5; the positioning frame 6 is provided with multiple sets of arrayed positioning holes 62, and the outer wall of the positioning frame 6 is provided with auxiliary ears 61, of which there are two sets. One set of auxiliary ears 61 is slidably connected to the positioning rod 4, and the other set of auxiliary ears 61 is threadedly connected to the lifting rod 3, so that when the lifting motor 5 is working, it can drive the positioning frame 6 to move up and down; the positioning holes 62 are slidably connected to the gas cylinder 9.

[0029] As one implementation method in this embodiment, in order to center and align the gas cylinders 9 in each set of positioning holes 62 when aligning the gas cylinders 9, a guide 7 with a trapezoidal cross section is provided on the inner wall of the positioning hole 62.

[0030] In one embodiment of this invention, the start / stop mechanism comprises: a bottom block 15 on the bottom surface of the fixed rod 14, and a set of positioning blocks 16 at the end of the bottom block 15, wherein the positioning blocks 16 are polygonal blocks; a moving block 18 at the end of the gas supply assembly 17, wherein the moving block 18 has a moving groove 181 that matches the positioning block 16; in order to start the gas supply assembly 17, a set of reciprocating cylinders 22 are provided on the outer wall of the fixed rod 14, and the extension end of the reciprocating cylinders 22 has a groove, wherein a set of connecting blocks 23 are fixed in the groove by bolts, and the connecting blocks 23 are slidably connected to the pressure rod on the gas supply assembly 17, thereby allowing the gas supply assembly 17 to contact the air inlet on the gas cylinder 9.

After aligning the air supply component 17 at the bottom of the fixed rod 14 with the air inlet of the gas cylinder 9, the reciprocating motor 19 on the base block 15 is started. The reciprocating motor 19 drives the gears. When gear 20 rotates, it drives the meshing rack 21 to move, causing the gas supply component 17 to move forward. The gas supply component 17 is stably moved by the cooperation of the moving block 18 and the positioning block 16. After the gas supply component 17 contacts the air inlet of the gas cylinder 9, the reciprocating cylinder 22 is activated. The telescopic end of the reciprocating cylinder 22 extends, and the connecting block 23 on its telescopic end pushes the pressure rod. Then, the gas supply component 17 is connected to the air inlet of the gas cylinder 9, and the control component 12 is activated.
