The position of the lifting assembly at the upper end of the support frame 4 can be adjusted by the second servo motor 14, the first screw 13, and the first guide rod 16. Specifically, the second servo motor drives the first screw 13 to rotate, which can drive the support frame 4 to move along the first guide rod 16. The provided lifting assembly can lift the valve above the placement plate 20 through the second opening and the first opening. Specifically, start the first servo motor 7 to unwind the cable 9 on the roller 8, so that the hook 10 passes through the second opening and the first opening, connect the hook 10 to the valve, and then wind up the cable 9 on the roller 8 by the first servo motor 7, thereby lifting the valve. Then close the placement plate 20, and the valve can be placed on the upper end of the placement plate 20 through the lifting assembly. At this time, the valve at the upper end of the support assembly 3 can be rotated by the power assembly. Specifically, the drive motor 17 drives the gear 18 to rotate, and the gear 18 meshes with the toothed ring 22, which can drive the support assembly 3 to rotate around the limiting groove 11 through the connecting ring 21, thereby adjusting the position of the valve and facilitating the maintenance of the valve.
