Above the oil pot 21, there is a three-stage hydraulic lifting cylinder 22, and the upper part of the three-stage hydraulic lifting cylinder 22 is connected in cooperation with a screw rod 23.

[0027] It should be noted that the lifting mechanism 2 includes an oil pot 21 installed above the bottom plate 1. Above the oil pot 21, there is a three-stage hydraulic lifting cylinder 22, and the upper part of the three-stage hydraulic lifting cylinder 22 is connected in cooperation with a screw rod 23. When lifting is required, the oil pump motor 12 or the air pump motor 13, the gear 10 and the planetary reducer 8 and the reducer assembly 9 connected thereto will drive the cam-type air pump piston 5 to move in the steel cylinder 6. The cam-type air pump piston 5 will drive the oil bladder 3 and the oil pump 4 connected thereto to move. The oil bladder 3 is connected to the oil pot 21, and the oil pot 21 and the three-stage hydraulic lifting cylinder 22 will push the screw rod 23 upward by means of the oil pump motor 12 or the air pump motor 13 to achieve lifting.

[0028] In the specific implementation process, such as Figure 1 As shown, the bottom plate 1 and the oil pot 21 are connected by welding.

The cam-type air pump piston 5 will drive the oil bladder 3 and the oil pump 4 connected thereto to move. The oil bladder 3 is connected to the oil pot 21, and the oil pot 21 and the three-stage hydraulic lifting cylinder 22 will push the screw rod 23 upward by means of the oil pump motor 12 or the air pump motor 13 to achieve extension, avoiding the situation that this device cannot be used when the oil pressure or the air pump fails. When using this device, the bottom plate is prevented from moving left and right, and the anti-slip particles 14 play an anti-slip role. The material used for the extension mechanism 2 is a friction-resistant material, which is high-density alloy steel.
