[0026] Specifically, the rack 403 extends to the center of the annular plate 4, and the clamping plate 404 is located at the center of the annular plate 4. Two groups of positioning plates 405 for limiting the moving range of the clamping plate 404 are installed inside the annular plate 4. The gap between the two groups of positioning plates 405 is fixedly installed with a connecting column 2 406 for fixing the connection between the two groups of positioning plates 405.

[0030] Example 2: Please refer to Figure 5 The outer wall of each group of annular plates 4 is fixedly installed with an auxiliary structure for assisting the clamping structure to move vertically up and down. The auxiliary structure includes a support plate 5, which is fixedly installed on the outer wall of the annular plate 4. A sliding ring 501 is fixedly installed on the outer surface of the support plate 5. The sliding ring 501 is slidably sleeved on the positioning rod 502, and the positioning rod 502 is fixedly installed in the gap between the fixed plate 2 and the connecting plate 3.

The rotating block 703 is fixedly connected to a clamp 704 by rotating a rotating shaft installed inside it, and the clamp 704 is fixedly installed on the bottom surface of the connecting plate 3. When the support rod 7 on one side moves upward, the connecting plate 3 will tilt, and then the support rod 7 drives the rotating block 703 to rotate inside the clamp 704 to solve the connection relationship between the adjustment structure on the other side and the connecting plate 3, avoiding wear between the two, so that the entire structure can maintain balance and stability under different conditions.

[0034] The working principle of the utility model is:

[0035] First, according to the horizontal state of the ground, pull the support rods 7 on both sides to move inside the adjusting rod 701. After adjusting to the appropriate height, turn the bolts and twist the adjusting ring 702 to make the support rods 7 and the adjusting rod 701 highly connected, so as to ensure the horizontal state of the device during operation. Then insert the piles from the fixing plate 2 and the connecting plate 3 into the ground, start the driving motor 410 to connect the rotating shaft 411 to drive the driving wheel 412 to control the rotation of the driven wheel 413, and then drive the connecting shaft 414 to connect a set of gears 402 to rotate through the driven wheel 413. This set of gears The wheel 402 is connected to the rotating rod 408 and the rotating ball 409 to realize the synchronous rotation of multiple sets of gears 402, so as to drive multiple sets of racks 403 and the clamping plate 404 to fix and clamp the outer surface of the pile, so as to facilitate the start of the cylinder 6 to connect the support plate 5 to drive the sliding ring 501 to move up and down along the positioning rod 502, and control the clamping structure to press the pile downward. In addition, when the cylinder 6 retracts, the driving motor 410 rotates in the opposite direction to contact the clamping and fixing of the outer surface of the pile, so as to facilitate the clamping structure to return to the original position with the cylinder 6 and perform the pressing operation again.
