[0022] A movable ring 2 is provided on the fixed tube 1. The outer side of the fixed tube 1 is annularly fixedly connected with a plurality of plug-in mechanisms. The tops of the plurality of plug-in mechanisms are fixedly connected to the bottom of the movable ring 2. The plug-in mechanisms include a fixed block 8. The fixed block 8 is fixedly connected to the outer side of the fixed tube 1. A first through hole is provided on the top of the fixed block 8. An insertion rod 9 is movably provided in the first through hole. The top of the insertion rod 9 is fixedly connected to the bottom of the movable ring 2. A plurality of insertion holes 10 are provided on the right sides of the two insertion rods 9 on the left and right sides. A slot 11 is provided on the side away from each other of the two fixed blocks 8 on the left and right sides. The slot 11 is cross-connected with the corresponding first through hole. A movable sleeve is provided in the slot 11. There is a T-shaped iron rod 12, and the inner walls of the two T-shaped iron rods 12 on the side away from each other are respectively fixed by magnetic attraction to the side away from each other of the two left and right fixing blocks 8, wherein the side away from each other of the two left and right fixing blocks 8 are both embedded and fixed with two magnets 13, and the magnets 13 are fixed by magnetic attraction to the corresponding T-shaped iron rods 12, and the T-shaped iron rod 12 is located between the two corresponding magnets 13, and the adsorption force of the magnets 13 and the T-shaped iron rod 12 can be used to quickly fix the T-shaped iron rod 12, and the T-shaped iron rod 12 is movably sleeved in a corresponding plug hole 10, and the cooperation of the T-shaped iron rod 12, the plug hole 10 and the slot 11 has the effect of vertically limiting the corresponding plug rod 9;

[0023] A groove 6 is provided on the side away from each other of the two relative moving blocks 4, and an inclined extrusion rod 7 is rotatably installed on the inner wall of the groove 6 away from its opening. The top of the extrusion rod 7 is hinged to the bottom of the moving ring 2, and the two relative extrusion rods 7 are symmetrically arranged. The extrusion rod 7 cooperates with the moving ring 2 to drive the corresponding moving block 4 to move horizontally. The utility model, through a series of structural arrangements, can increase the fixed support area of ​​the spiral ground pile 100 by clamping and fixing the matching insertion rod 9 and inserting it into the underground support, thereby achieving vertical and stable fixation of the spiral ground pile 100 and reducing the risk of tilting during use.

[0024] Working principle: When in use, after the spiral pile 100 is screwed into the ground, the fixing pipe 1 is sleeved on the spiral pile 100. When the bottom end of the fixing pipe 1 contacts the ground, the two T-shaped iron rods 12 are pulled away from each other, and the T-shaped iron rods 12 are moved out of the corresponding slots 11 and separated from the magnets 13, thereby releasing the fixation of the insertion rods 9. Then, the moving ring 2 can be knocked downward with the help of a tool, and the moving ring 2 drives multiple insertion rods 9 to be inserted downward into the soil. While the moving ring 2 moves downward, it also squeezes multiple extrusion rods 7. The extrusion force causes the extrusion rods 7 to move and rotate. The extrusion rods 7 squeeze and drive the corresponding moving block 4 to move in the direction close to the spiral pile 100. The moving block 4 drives the corresponding elastic anti-slip rubber 5 to move until it is in close contact with the outside of the spiral pile 100. While the moving block 4 moves, it also drives the corresponding guide rod 15 to move in the guide block 16 slides, and the moving block 4 also compresses the corresponding spring 17 while moving. When the multiple elastic anti-skid rubbers 5 are in close contact with the outer side of the spiral pile 100, the knocking on the moving ring 2 is stopped, and the T-shaped iron rod 12 passes through the aligned jacks 10 and is inserted into the corresponding slots 11. The T-shaped iron rod 12 is adsorbed with the corresponding magnets 13, thereby realizing the vertical position restriction of the left and right side plug rods 9, thereby realizing the position fixation of the moving ring 2 and the fixed tube 1, and because the multiple elastic anti-skid rubbers 5 are in close contact with the outer side of the spiral pile 100 at this time, the spiral pile 100 and the fixed tube 1 can be fixed, thereby realizing the vertical fixation of the spiral pile 100, and the multiple plug rods 9 are inserted into the ground, which can increase the fixed support area of ​​the spiral pile 100, thereby improving the fixing stability and reducing the risk of tilting during use;

[0025] When it is necessary to release the fixation of the spiral ground pile 100, the T-shaped iron rod 12 is pulled out from the corresponding slot 11 again to release the fixation of the insertion rod 9 and the moving ring 2. At this time, the moving ring 2 can be pulled upward to release the squeezing force on the multiple squeezing rods 7, thereby releasing the squeezing force on the moving block 4. The elastic force of the spring 17 in the compressed state drives the corresponding moving block 4 to move away from the spiral ground pile 100, and the moving block 4 drives the corresponding elastic anti-slip rubber 5 to separate from the spiral ground pile 100, thereby releasing the fixation of the spiral ground pile 100.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
