The universal casters 11 are locked so that they cannot rotate, so as to fix the position of the support tripod 1 and prevent the support tripod 1 from being displaced during operation. The support tripod 1 supports the electric telescopic rod 2, the electric telescopic rod 2 supports the support plate 21, the support plate 21 supports the cross hollow plate 31, the cross hollow plate 31 supports the support frame 3, and the electric telescopic rod 2 can be extended and retracted, so that the height of the support plate 21 can be adjusted with the electric telescopic rod 2. The telescopic length of the retractable rod 2 can be adjusted and changed, which is convenient for flexible use to cope with the top plate positions at different heights. The support frame 3 is connected to the support plate 21 by a cross hollow plate 31. The interior of the cross hollow plate 31 is hollow to reduce the deadweight of the device. The support frame 3 supports the lifting plate frame 33 through a plurality of springs 34. The lifting plate frame 33 supports the disassembled top plate. The lifting plate frame 33 slides downward under the influence of the weight of the top plate. The lifting plate frame 33 squeezes and shortens a plurality of springs 34, so that the support frame 3 can surround the top plate. At this time, the support frame 3 The top plate is limited to prevent it from slipping and falling on the lifting plate frame 33, thereby improving the stability and protection of the top plate support. The support frame 3 uses a plurality of clearance notches 32 to achieve vacancy, which is convenient for taking the top plate, and the positions of the plurality of clearance notches 32 are distributed differently, which is convenient for taking the top plate from different positions. The support plate 21 and the electric-controlled telescopic rod 2 are designed to rotate, so that when the staff pushes the support frame 3 to rotate, the support frame 3 drives the support plate 21 to rotate through the cross hollow plate 31, so that the top plate can change its angle, thereby The supporting leg 1 is kept stationary, while the supporting frame 3 and the lifting plate frame 33 can drive the top plate to change at multiple angles, so that in the narrow space in the through passage, the supporting frame 3 can make way for the staff's working area, reducing the impact of the device's position on the movement of the workers, thereby reducing the frequency of adjusting the position of the supporting leg 1, thereby reducing the locking and unlocking control of the universal caster 11, and the operation is simple and convenient. In addition, the sliding connection relationship between the cross hollow plate 31 and the supporting plate 21 enables the supporting frame 3 to expand the range of movement, facilitate the disassembly and assembly of the top plate, and improve flexibility.

[0019] Two limiting rods 22 are fixedly connected to the inner wall of the limiting slide groove 211, and the two limiting rods 22 both penetrate the side wall of the connecting slider 311; the limiting slide groove 211 limits the connecting slider 311 through the two limiting rods 22 to prevent the connecting slider 311 from detaching from the limiting slide groove 211 and further improve the stability of the connecting slider 311 when sliding.

[0020] A plurality of damping pads 23 are fixedly connected to the top of the electric-controlled telescopic rod 2, and the damping pads 23 are slidably connected to the bottom of the support plate 21. The side walls of the two limit rods 22 are wrapped with a damping outer layer 221, and the limit rods 22 are slidably connected to the inner wall of the connecting slider 311 through the damping outer layer 221; the damping pads 23 apply resistance to the rotation of the support plate 21, thereby improving the stability of the support plate 21 when it stops rotating, and the limit rods 22 contact the inner wall of the connecting slider 311 through the damping outer layer 221. The damping outer layer 221 applies resistance to the sliding of the connecting slider 311, thereby improving the stability of the connecting slider 311 when it stops sliding, and avoiding the top plate from shaking.
