In this state, the height adjustment of the single-sided single stretchable-supporting foot 20 of the moving base 12 is achieved.
Third, when the first stop lever 2412 leaves the first stop collar 2402, the second stop lever 2413 falls into the third bayonet 2409 of the second gear groove 2408, and the third stop lever 2414 leaves the second stop collar 2403, as shown in fig. 7. At this time, when the second control handle 2404 drives the linkage shaft 2401 to rotate, the linkage shaft 2401 drives the second stop collar 2403 to rotate through the second stop lever 2413, and the second stop collar 2403 drives the corresponding other vertical telescopic support rod 21 to vertically extend and retract, so as to realize the height adjustment of the other stretchable support leg 20; since the first stopper rod 2412 is separated from the first stopper rod 2402, the first stopper rod 2402 is not acted upon when the linkage shaft 2401 rotates. In this state, the height adjustment of the single side of the mobile base 12 and the other single stretchable support foot 20 is achieved.
The first stop collar 2402 and the second stop collar 2403 drive the vertical telescopic stay bar 21 to vertically extend and retract in a linkage manner, which can be any one of screw drive, gear drive, worm drive, chain drive or belt drive.
The rest of the structure is the same as that of the third embodiment.
When the leveling rod lifting device is used, the horizontal transverse frame 1 is mainly used for adjusting angles, positioning and conveniently moving the leveling rod lifting frame 3, the leveling rod lifting frame 3 can be automatically moved at one end of the horizontal transverse frame 1 through the second horizontal sliding mechanism 7, and the leveling rod fixing seat 8 and the leveling rod lifting frame 3 are driven to rotate by the leveling rod fixing seat 8 through the second lifting rotating mechanism 10. The horizontal cross frame 1 can slide back and forth through the first horizontal sliding mechanism 6, the overall adjustment of the height is realized through the first lifting mechanism 2, the horizontal rotation is realized through the first horizontal rotating mechanism 5, the multi-angle flexible rotation and adjustment of a plurality of parts are realized, the leveling rod is flexibly and conveniently driven to level the ground, and the height adjustment can also realize independent adjustment in 4 directions or synchronous adjustment in 2 directions.
