[0024] In a preferred embodiment, the outer wall of the rotating shaft 4 is slidably connected to a threaded rod 12, one end of the connecting plate 11 passes through the interior of the threaded rod 12 and the connecting plate 11 is slidably connected to the threaded rod 12. When the threaded rod 12 moves, the threaded rod 12 can drive the connecting plate 11 to move, so that the threaded rod 12 can drive the rotating shaft 4 to move through the connecting plate 11.

[0025] In a preferred embodiment, the end of the threaded rod 12 away from the rotating shaft 4 passes through the outer wall of the support seat 2 and the threaded rod 12 is connected to the support seat 2 by a thread. A support column 13 is fixedly connected to the top of the support seat 2. When the rotating shaft 4 moves, the rotating shaft 4 can move inside the working groove 3, so that the rotating shaft 4 can drive the extrusion plate 5 to move.

[0026] In a preferred embodiment, a slide groove 14 is provided on the top of the support column 13, and a support rod 15 is slidably connected inside the slide groove 14. An adjustment groove 16 is provided inside the support seat 2, and a pull rod 17 is provided inside the adjustment groove 16. Both ends of the pull rod 17 respectively pass through the slide groove 14 and the outer wall of the support column 13, and the pull rod 17 is slidably connected to the support column 13. When the pull rod 17 moves, the pull rod 17 can move inside the adjusting groove 16, and at the same time, the pull rod 17 can move inside the slide groove 14.

[0027] Working principle of the utility model: when the device is used, when the size of the circular hole 8 on the support seat 2 is larger than the size of the embedded hole, the circular hole 8 is located at the top of the embedded hole, so that the small head of the embedded bolt passes through the circular hole 8 and enters the embedded hole. At this time, the threaded rod 12 is rotated to make the threaded rod 12 rotate slightly inside the working groove 3. The threaded rod 12 can drive the connecting plate 11 to move, so that the connecting plate 11 moves in a small circular motion inside the working groove 3. The connecting plate 11 will also drive the rotating shaft 4 to move, so that the rotating shaft 4 rotates slightly inside the working groove 3. The rotating shaft 4 will drive the extrusion plate 5 to move, so that the extrusion plate 5 rotates slightly inside the working groove 3. The outside of the extrusion plate 5 is provided with an inclined surface, so that when the inclined surface of the outer wall of the extrusion plate 5 reaches one side of the roller 7, the extrusion plate 5 can move against the roller The wheel 7 is extruded, so that the roller 7 will rotate on the outer wall of the inclined surface of the outer wall of the extrusion plate 5, and the roller 7 can slide inside the working groove 3. The roller 7 can also drive the extrusion rod 6 to move, so that the extrusion rod 6 slides inside the working groove 3, and the extrusion rod 6 slides inside the extrusion groove 9. At the same time, the extrusion rod 6 can drive the extrusion block 10 to move, so that the extrusion block 10 can move inside the extrusion groove 9. At the same time, the extrusion block 10 can enter the circular hole 8 from the extrusion groove 9, so that the extrusion block 10 can extrude the embedded bolts inside the circular hole 8. When the extrusion block 10 contacts and extrude the outer wall of the embedded bolt, the position of the big head of the embedded bolt can be engaged and fixed, thereby preventing the circular hole 8 from being too large to fix the position of the embedded bolt.

[0028] See also Figure 1 and Figure 3 The utility model provides a technical solution: a limiting groove 18 is provided on the outer wall of the support rod 15, one end of the pull rod 17 is slidably connected to the limiting groove 18, and a movable plate 19 is fixedly connected to the outer wall of the pull rod 17. When the roller 7 moves, the roller 7 can drive the extrusion rod 6 to move, and the extrusion rod 6 will drive the extrusion block 10 to move.

[0029] In a preferred embodiment, a spring 20 is fixedly connected to the outer wall of the movable plate 19, and one end of the spring 20 is fixedly connected to the outer wall of the movable plate 19. When the movable plate 19 moves, the movable plate 19 will move inside the adjustment groove 16, and the movable plate 19 will drive the spring 20 to move.

[0030] The working principle of the utility model is as follows: when the device is used and the height of the equipment needs to be adjusted, the pull rod 17 is pulled to make the pull rod 17 move inside the adjusting groove 16. The pull rod 17 also drives the movable plate 19 to move, so that the movable plate 19 can move inside the adjusting groove 16, so that the movable plate 19 can squeeze the spring 20. At the same time, one end of the pull rod 17 is separated from the limiting groove 18. At this time, the support rod 15 is pulled to make the support rod 15 slide inside the slide groove 14. When the height of the support rod 15 reaches a suitable position, the pull rod 17 is released. The squeezing force of the spring 20 makes the movable plate 19 return to the initial position, and then the movable plate 19 drives one end of the pull rod 17 to enter the limiting groove 18, so that the height of the equipment is convenient for subsequent adjustment.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
