[0046] When the supporting angle block 91 is fixed to the wall by bolts, the force-bearing disc 101 can be pulled by the grip rod to rotate forward, the force-bearing disc 101 rotates forward to drive the positioning screw rod 102 to rotate forward, the positioning screw rod 102 rotates forward to drive the positioning cross plate 103 to move backward, the second reset spring 105 is compressed, the positioning cross plate 103 moves backward to drive the first connecting block 106 to move backward, the first connecting block 106 moves backward to drive the fixing sleeve 107 to move backward, the fixing sleeve 107 moves backward to drive the buffer push rod 108 to move backward, the buffer push rod 108 moves backward to drive the second connecting block 1010 to move backward The second buffer spring 109 plays a buffering role, the second connecting block 1010 moves backward to drive the positioning push plate 1011 to move backward, the positioning push plate 1011 moves backward to drive the adsorption rubber disc 1012 to move backward, the adsorption rubber disc 1012 moves backward to contact and adsorb on the wall, if the device needs to be removed, pull the force disc 101 to reverse, the positioning screw rod 102 drives the positioning horizontal plate 103 to move forward, the second reset spring 105 plays an assisting role, the positioning push plate 1011 also drives the adsorption rubber disc 1012 to move forward and reset, so that it can be better fixed on the wall.

[0047] When the device is fixed at a high place on the wall, the force-bearing disc 101 is pulled to rotate forward, the second connecting block 1010 moves backward to drive the first piston rod 112 to move backward, and the first piston rod 112 moves backward to discharge the hydraulic oil in the first hydraulic cylinder 111 into the second hydraulic cylinder 119 through the guide tube 113, so that the second piston rod 118 moves downward, and the second piston rod 118 moves downward to drive the hinged cylinder 117 to move downward, and the hinged cylinder 117 moves downward to drive the first connecting column 116 to swing downward, and the first connecting column 116 swings downward through the movable connecting frame 114 to drive the sliding sleeve 115 to swing downward, and then the universal ball seat 1112 contacts the ground for support.

[0049] Example 3

[0050] On the basis of Example 1 and Example 2, Fig.13 and Fig.16 As shown, it also includes a limiting mechanism 13, which includes a limiting screw 131, a synchronous belt assembly 132 and a protective bottom cover 133.

The pulleys are both installed at the lower part of the limiting screw 131, and the belt is wound between the two pulleys.

[0051] When the device needs to be placed on the ground, the limit screw 131 on one side can be twisted to rotate. The rotation of the limit screw 131 on one side drives the synchronous belt assembly 132 to rotate. The rotation of the synchronous belt assembly 132 drives the limit screw 131 on the other side to rotate. Therefore, the limit screw 131 rotates to adjust the upper and lower positions of the buffer bottom plate 6. After the adjustment of the buffer bottom plate 6 is completed, stop twisting the limit screw 131 to rotate. In this way, it is convenient for people to adjust the buffer bottom plate 6.
