By setting the lifting component, the height of the fixed cylinder 3 can be adjusted, so that the top plate 2 can be kept horizontal when the device is placed in an uneven position, thereby improving the stability of the device when in use. By setting the universal wheel 18, the movement of the device can be facilitated, and the position of the device can be easily transferred, thereby improving the convenience of the device when in use.

[0022] In this embodiment, the lifting assembly includes a screw 4, a driving assembly, a moving cylinder 9 and a connecting assembly. The top end of the screw 4 is rotatably connected to the top end of the inner cavity of the fixed cylinder 3 through a bearing. The driving assembly is arranged at the top end of the inner cavity of the fixed cylinder 3 and is fixedly sleeved on the outer wall of the screw 4. The moving cylinder 9 is screwed on the outer wall of the screw 4 and fixedly connected to the top end of the universal wheel 18. The two connecting assemblies are both arranged on the inner wall of the fixed cylinder 3 and are respectively fixedly connected to the two sides of the outer wall of the moving cylinder 9. The screw 4 is rotated by the driving assembly. Under the action of the rotational force of the thread on the outer wall of the screw 4, when the screw 4 rotates, the moving cylinder 9 can drive the universal wheel 18 to slide up and down along a straight line under the limiting action of the connecting block 11 and the connecting groove 10.

A plurality of limit assemblies are arranged on the inner wall of the casing 12 and are respectively fixedly connected to the outer walls of the two adjustment cylinders 15, so that the dual-axis motor 13 drives the two screw rods 14 to rotate. The threads on the outer walls of the screw rods 14 are arranged relatively to each other. Therefore, when the two screw rods 14 rotate, the two adjustment cylinders 15 can slide relatively to each other at the same time under the limiting action of the limiting groove 16 and the limiting block 17, thereby adjusting the distance between the two beams 1 and folding the two top plates 2, thereby adjusting the volume of the device, making it convenient to reduce its volume to a size smaller than the width of the car, thereby solving the problem that the steel structure platform in the prior art will block the driver's view of the rearview mirror due to its wide width during transportation, affecting the safety during transportation.

[0029] The double-axis motor 13 is started to drive the two screw rods 14 to rotate. Since the outer wall threads of the two screw rods 14 are arranged relatively, when the two screw rods 14 rotate, the two adjustment cylinders 15 can slide relatively at the same time under the limiting action of the limiting groove 16 and the limiting block 17, thereby adjusting the distance between the two cross beams 1 and folding the two top plates 2, thereby adjusting the volume of the device, making it convenient to reduce its volume to a size smaller than the width of the car, and solving the problem that the steel structure platform in the prior art will block the driver's view of the rearview mirror due to its wide width during transportation, affecting the transportation. In order to solve the problem of safety during the transmission process, the turntable 6 is rotated to drive the driving gear 7 to rotate through the rotating column 5, thereby rotating the screw 4. Under the action of the rotational force of the thread on the outer wall of the screw 4, when the screw 4 rotates, the moving cylinder 9 can drive the universal wheel 18 to slide up and down along a straight line under the limiting action of the connecting block 11 and the connecting groove 10, so that the top plate 2 can be kept horizontal when the device is placed in an uneven position, thereby improving the stability of the device when in use. Through the arrangement of the universal wheel 18, the movement of the device can be facilitated, and then the position of the device can be easily transferred, thereby improving the convenience of the device when in use.
