The elevator assembly 2 is controlled by the control box 25 inside the bottom sealing seat 1 and the external control interface 26. When the elevator assembly 2 is used for linear track travel, it can no longer be used with the track due to the action of the universal wheel 4, resulting in its inability to run in a straight line normally. When it is used for linear track travel, the worm 10 drives the worm wheel 9 to rotate by manually adjusting the rotary handle 11, so that the screw rod rotates to carry out Adjust the position of the mounting block 12 so that the two track wheels 13 at the bottom of the two mounting blocks 12 match the track at the position in use, then move the track wheel 13 onto the track, and then manually adjust the hexagonal threaded cap 20 at the top of the third screw rod 16 to rotate the third screw rod 16, so that the threaded block 17 on the surface of the third screw rod 16 moves downward, so that the limiting sleeve 18 pushes the position of the universal wheel 4 to change, so that the bottom of the universal wheel 4 on the front side of the bottom sealing seat 1 contacts the ground, thereby ensuring that the bottom sealing seat 1 is still in a balanced state at the top of the track, so that the bottom sealing seat 1 drives the elevator assembly 2 to move on the track surface, so that the device is suitable for track movement and non-track movement, making it more applicable.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
