[0027] The bottom end of the rear side of the lifting frame 1 is fixedly connected to a counterweight box 19, and the bottom end of the counterweight box 19 is fixedly connected to a number of sharp cones, which are recovered in the interior of the threaded sleeve 16 through the threaded rod 10, and the universal wheel 8 is recovered. At this time, the sharp cones are inserted into the ground to play a role of limiting and stabilizing the fixation. A driving motor 11 is provided on both sides of the internal top of the counterweight box 19. By driving the driving motor 11, the threaded sleeve 16 is rotated, and after rotation, it is threadedly matched with the threaded rod 10 to realize threaded movement. The driving end of the driving motor 11 is fixedly connected to the threaded sleeve 16, and the bottom end of the driving motor 11 is fixedly connected to the lifting buffer plate 15. The internal thread of the threaded sleeve 16 is connected to the threaded rod 10, and the bottom end of the threaded rod 10 is rotatably connected to the universal wheel 8. It extends toward the wheel 8 and is supported on the ground after extension, so that position movement can be achieved. The top four corners of the top lifting buffer plate 15 and the bottom four corners of the bottom lifting buffer plate 15 are fixedly connected with shock-absorbing springs 13. The internal sleeve of the shock-absorbing spring 13 is provided with a shock-absorbing damping. The shock-absorbing damping is used in conjunction with the internal part of the shock-absorbing spring 13 to achieve a shock-absorbing effect, which facilitates position movement. One end of the shock-absorbing spring 13 and the shock-absorbing damping are fixedly connected to a support block 14. The support block 14 is fixedly connected to the inner wall of the counterweight box 19. Both sides of the threaded rod 10 are fixedly connected to the limit rod 9.
