[0026] Working principle:

[0027] When the present invention is in use, a heavy object is placed on the top block 11. When the height of the heavy object needs to be adjusted, it is only necessary to insert the hexagonal wrench into the hexagonal groove 9 and apply a rotational force to rotate the worm 72, thereby driving the worm wheel 73 to rotate. At this time, the support rod 4 rotates under the drive of the worm 72. At this time, the top block 11 and the top rod 6 cannot move under the gravity of the heavy object, and the internal thread 74 inside the support rod 4 and the external thread 75 on the top rod 6 cooperate to realize the lifting and lowering of the top rod 6. When the gravity of the heavy object exceeds the elastic force of the four springs 82, the pulley 3 squeezes the spring 82 through the guide rod 84 and the slider 83. When the structural frame 1 descends to the ground, it contacts the ground to generate friction, which locks the device. The spring 82 is provided in the connecting block 2 to reduce shock, which is convenient for moving in various complex terrains.
