When the upright column 50 is fixed on the ground, the screwing button 1003 is rotated downwards until the suction cup 1004 is sucked on the ground, so that the upright column 50 can be fixed on the ground, and the lifting trolley is fixed.

As shown in fig. 4 and 5, a vacuum extractor 1005 and an air extraction hose 1006 are further provided to enhance the fixing strength of the column 50. The two vacuumizers 1005 are correspondingly arranged on the upper end surfaces of the two mounting plates 1001; the upper end surfaces of the two screwing buttons 1003 are respectively provided with an air suction hole downwards; the two rotating rods 1002 are both hollow structures so as to correspondingly communicate the two air suction holes and the two suckers 1004; the first ends of the two air-extracting hoses 1006 are correspondingly communicated with the two air-sucking holes, and the second ends of the two air-extracting hoses 1006 are correspondingly connected with the two vacuumizers 1005.

After the suction cup 1004 is sucked on the ground, the vacuum extractor 1005 is used for extracting air from a blind cavity formed by the suction cup 1004 and the ground through the air extraction hose 1006, so that an air pressure difference is formed between the inside and the outside of the formed blind cavity, and the suction cup 1004 is pressed on the ground under the action of pressure, thereby further improving the fixing strength of the upright post 50.

The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
