[0031] Reference Figure 2 and Figure 3 The outer wall of the first connecting rod 5 is fixedly connected with an outer arc plate 13, and the left end of the outer wall of the outer arc plate 13 is fixedly connected to the left side of the outer wall of the positioning ring 4; the bottom wall of the sliding plate 201 is fixedly connected with a spring 16, and the end of the spring 16 is fixedly connected to the top of the base 1; the outer wall of the rotating column 7 is equidistantly fixedly connected with a plurality of rotating rods 12;

[0032] Specifically, by fixing the outer arc plate 13 on the outer wall of the positioning ring 4, the positioning ring 4 can be further fixed to the outside of the column 3 to ensure the stability of the device; a spring 16 is provided on the bottom wall of the sliding plate 201 to increase the buffering force of the device, so that the placement box 203 falls stably and slowly after being subjected to the gravity of the equipment top rod 11; by fixing a plurality of rotating rods 12 on the outer wall of the rotating column 7, it is convenient for the operator to rotate the threaded rod, thereby improving the convenience of the device.

[0033] Working principle: a column 3 is fixedly connected to the top of the base 1. The base 1, as a fixed supporting point of the device, needs to have a certain area. A first connecting rod 5 is fixedly connected to the middle and upper part of the front outer wall of the column 3. A positioning ring 4 is arranged on the front side of the column 3. The positioning ring 4 is fixedly connected to the column 3 through the first connecting rod 5. In order to further improve the stability of the positioning ring 4, an outer arc plate 13 is fixedly connected to the outer wall of the first connecting rod 5. The left side of the outer wall of the outer arc plate 13 is fixedly connected to the outer wall of the positioning ring 4. Threaded holes 6 are provided on the left and right ends of the outer wall of the positioning ring 4. The main threaded rod 8 is threadedly connected to the threaded hole 6 on the right side, and the secondary threaded rod 9 is threadedly connected to the threaded hole 6 on the left side. The outer walls of the main threaded rod 8 and the secondary threaded rod 9 are fixedly connected to the rotating column 7.

By setting the rotating rod 12, the operator can more conveniently rotate the rotating column 7. When in use, the device top rod 11 is placed in the positioning ring 4, and the main threaded rod 8 and the secondary threaded rod 9 can be controlled by rotating the rotating column 7 to clamp the device top rod 11. When the device top rod 11 needs to be replaced, it is only necessary to reversely rotate the rotating column 7 of the main threaded rod 8 to loosen the device top rod 11, and slide the sliding plate 201 in the lower middle part of the outer wall of the column 3. The outer wall of the sliding plate 201 is fixedly connected to the second connecting rod 202, and a placement box 203 is set on the same vertical line of the positioning ring 4. The placement box The outer wall of 203 is fixedly connected to the second connecting rod 202. When the fixed top rod 11 is replaced, the device top rod 11 will fall into the placement box 203. The spring 16 is fixedly connected to the bottom wall of the sliding plate 201. The spring 16 can provide a certain buffer for the device, so that the placement box 203 can fall slowly and steadily. At the same time, a shock-absorbing layer 14 is provided on the inner bottom wall of the placement box 203, which can further reduce the impact caused by the device top rod 11 falling on the placement box 203, thereby ensuring the service life of the device.
