[0032] The working principle of this utility model:

[0033] When installing the tailgate of a car, the column 101 is tilted away from the lower support 102, so that the main body of the device is moved to the vicinity of the tailgate of the car through the support wheel 104. Then, the electric cylinder 106 is started to drive the adjustment mechanism 2 to rise and fall as a whole. The upper support 209 is close to the bottom surface of the tailgate of the car, and the slider 207 is pushed downward. The positioning tooth 206 is pulled into the crank 203 through the connecting rope 205, and the positioning tooth 206 is separated from the tooth groove 202. At this time, the crank 203 is pushed and the upper support 209 is driven to rotate around the center of the tooth groove 202. When most of the suction cups 216 contact the bottom surface of the tailgate of the car, the upper support 209 is moved upward and downward. After the car tailgate is opened, the movable sleeve 214 is twisted. Driven by the threads on the surface of the threaded barrel 211, the movable sleeve 214 can be raised and lowered inside the sealing ring 215. By adjusting the movable sleeve 214 one by one, each suction cup 216 is pressed against the car tailgate. Then the vacuum pump 218 is started to drive the negative pressure in the vacuum chamber 210 through the connecting pipe 217. At the same time, the air at the connection between the suction cup 216 and the car tailgate is extracted by the vacuum pump 218. Afterwards, under the action of atmospheric pressure, the suction cup 216 and the car tailgate are adsorbed and fixed to each other. At this time, the upper support 209 as a whole supports the car tailgate.
