The top end of the central shaft 3 is installed with a movable plate 4 through bolts, the bottom end of the movable plate 4 is installed with a spring 5 through bolts, a rotating sleeve 6 is sleeved on the central shaft 3, one end of the spring 5 away from the movable plate 4 is connected with the rotating sleeve 6 through bolts, a support plate 7 is installed on the side wall of the rotating sleeve 6 through bolts, a convex block 8 is welded at the bottom of the support plate 7, a connecting rod 9 is installed at the bottom of the central shaft 3 through bolts, and a mounting member 10 is installed at the bottom of the connecting rod 9 through bolts.

[0022] The base 1 is of a circular structure, and a limit groove is provided at one end of the limit sleeve 2 away from the center of the base 1; by rotating the wrench, at this time the wrench drives the mounting member 10 to rotate, and the mounting member 10 drives the connecting rod 9 to rotate, the connecting rod 9 drives the central shaft 3 to rotate, and the central shaft 3 drives the movable plate 4 to rotate. During the rotation of the movable plate 4, the protruding part below it will push the support plate 7 to rotate, and the rotation of the support plate 7 will drive the rotating sleeve 6 to rotate with it. During the rotation of the support plate 7, it will gradually rotate to the position of the limit groove on the limit sleeve 2;

[0023] The central shaft 3 is of an eccentric circle structure when viewed from below; by rotating the mounting member 10, the central shaft 3 will continue to rotate a little, and finally the central shaft 3 will be clamped with the through hole of the rotating sleeve 6, achieving the effect of locking the rotating sleeve 6 so that it cannot slide up and down anymore;

[0024] An eccentric circle through hole is provided inside the rotating sleeve 6, and the central shaft 3 is nested with the through hole inside the rotating sleeve 6; the spring 5 pushes the rotating sleeve 6 to move downward and fall into the limit groove;

[0025] The support plate 7 is of a Z-shaped structure, the convex block 8 is made of rubber material, and the convex blocks 8 are evenly distributed on the bottom surface of the support plate 7; the rotation of the rotating sleeve 6 drives the support plate 7 to rotate together, and at the same time the support plate 7 will also fall into the limit groove together with the rotating sleeve 6. At this time, the support plate 7 cannot rotate anymore under the restriction of the limit groove;

[0026] The bottom of the mounting member 10 is provided with a mounting groove, and the mounting groove is a regular hexagon when viewed from above; by pressing the mounting groove at the bottom of the mounting member 10 with a wrench and turning the wrench, the wrench drives the mounting member 10 to rotate, and the mounting member 10 drives the connecting rod 9 to rotate.

[0027] At the same time, the contents not described in detail in this specification belong to the prior art known to technicians in this field.

[0028] Working principle: When in use, first put the device into the top fixing groove, then use a wrench to press against the mounting groove at the bottom of the mounting piece 10, and turn the wrench. At this time, the wrench drives the mounting piece 10 to rotate, and the mounting piece 10 drives the connecting rod 9 to rotate, and the connecting rod 9 drives the middle axis 3 to rotate, and the middle axis 3 drives the movable plate 4 to rotate. During the rotation of the movable plate 4, the raised part below it will push the support plate 7 to rotate, and the rotation of the support plate 7 will drive the rotating sleeve 6 to rotate together with it, and during the rotation of the support plate 7, it will gradually rotate to the position of the upper limit groove of the limit sleeve 2, and at this time the spring 5 will push the rotating sleeve 6 The support plate 7 moves downward and falls into the limit groove, and the support plate 7 will also fall into the limit groove together with the rotating sleeve 6. At this time, the support plate 7 cannot rotate any more under the restriction of the limit groove, and then the mounting member 10 continues to rotate, so that the central axis 3 will continue to rotate a little, and finally the central axis 3 will be clamped with the through hole of the rotating sleeve 6 to achieve the effect of locking the rotating sleeve 6, so that it can no longer slide up and down, and the installation is completed. At this time, the support plate 7 is against the top wall, supporting the base 1 so that it will not fall, and the convex block 8 on the bottom surface of the support plate 7 will increase the friction between the support plate 7 and the top wall, so that the support plate 7 will not slide, further increasing the stability of the device;

[0029] When the equipment needs to be disassembled, it is necessary to use a wrench to press against the installation groove at the bottom of the mounting piece 10, and rotate the wrench in the opposite direction to that during installation. At this time, the wrench drives the mounting piece 10 to rotate, and the mounting piece 10 drives the connecting rod 9 to rotate, and the connecting rod 9 drives the central axis 3 to rotate. The rotation of the central axis 3 will make the central axis 3 and the rotating sleeve 6 no longer clamped. At this time, the rotating sleeve 6 can slide up and down on the central axis 3 again. At this time, pull the base 1 to make it move downward, and then continue to turn the wrench. At this time, the support plate 7 will leave the limiting groove of the limiting sleeve 2 and no longer press against the top wall. At this point, the disassembly of the device is completed, and the device can be taken out from the fixing groove of the top wall.
