[0005] Furthermore, the limiting frame includes multiple circular rods located inside the hollow tube. Adjacent circular rods are connected by multiple connecting rods. The circular rods and circular holes correspond one-to-one. Limiting slides are welded on both sides inside the circular rods. A positioning rod is installed on the uppermost circular rod, and the positioning rod is placed at the top of the hollow tube.

[0006] Furthermore, an arc-shaped protective plate is welded onto the circular rod, and the arc-shaped protective plate is located at the circular hole.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] This utility model provides, for example Figures 1-4 The spiral pile shown includes a hollow tube 1, with a conical tip 2 welded to the lower end of the hollow tube 1, a spiral plate 3 welded to the outside of the hollow tube 1, a pusher frame 4 inside the hollow tube 1, multiple telescopic rods 5 installed on the pusher frame 4, multiple round holes 6 opened on the hollow tube 1, the pusher frame 4 can push the telescopic rods 5 out of the round holes 6, and a limit frame 7 is installed inside the hollow tube 1 to limit the telescopic rods 5.

[0018] The installation process of this spiral pile is as follows: Under normal conditions, the telescopic rod 5 is located inside the hollow tube 1. The hollow tube 1 can be easily screwed into the ground through the conical tip 2 and the spiral plate 3. After the hollow tube 1 is installed, the telescopic rod 5 can be pushed outward by the push frame 4, so that the telescopic rod 5 can pass through the round hole 6 and be inserted into the ground. The limiting frame 7 can ensure the direction of movement of the telescopic rod 5.

[0019] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 The limiting frame 7 includes multiple circular rods 8 located inside the hollow tube 1. Adjacent circular rods 8 are connected by multiple connecting rods 9. The circular rods 8 and the circular holes 6 correspond one-to-one. Limiting slides 10 are welded on both sides inside the circular rods 8. A positioning rod 11 is installed on the uppermost circular rod 8 and is placed at the top of the hollow tube 1.

[0020] The process of limiting the telescopic rod 5 by the limiting frame 7 is as follows: the ring rod 8 can be fixed on one side of the round hole 6 by the positioning rod 11. When the telescopic rod 5 extends or retracts, the telescopic rod 5 can be limited by the limiting slide 10.

[0021] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 An arc-shaped protective plate 12 is welded onto the circular rod 8. The arc-shaped protective plate 12 is located at the circular hole 6, which can prevent soil from entering the hollow tube 1 when it moves downward to the ground. After the hollow tube 1 is installed, the circular rod 8 is rotated, which in turn drives the arc-shaped protective plate 12 to rotate and exposes the circular hole 6, making it easy for the telescopic rod 5 to extend out from the circular hole 6.

[0022] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Included with instruction manual Figure 4The pusher frame 4 includes a square lifting rod 13 located inside the hollow tube 1. Multiple baffles 14 are welded on the square lifting rod 13. A square notch 15 is opened on one side of the telescopic rod 5. The telescopic rod 5 is fitted onto the outside of the square lifting rod 13 through the square notch 15. The telescopic rod 5 is placed on the baffle 14. Guide grooves 16 are opened on both sides inside the square notch 15. Guide wheels 17 are provided in the guide grooves 16. The guide wheels 17 are installed on the square lifting rod 13. The telescopic rod 5 can be placed on the limiting slide 10.

[0023] The process of the pusher 4 pushing the telescopic rod 5 is as follows: the telescopic rod 5 can be intercepted by the baffle 14, the guide wheel 17 is placed in the guide groove 16, and the telescopic rod 5 can be limited. When the telescopic rod 5 points to the round hole 6, the square lifting rod 13 is pushed downward. The limiting slide 10 can limit the telescopic rod 5 to prevent the telescopic rod 5 from moving downward. Then, when the guide wheel 17 moves downward, the telescopic rod 5 can be pushed to one side by the guide groove 16.

[0024] Refer to the instruction manual appendix Figure 4 The telescopic rod 5 includes a tapered rod 18, a cylindrical rod 19 is installed at one end of the tapered rod 18, and a square rod 20 is installed on one side of the cylindrical rod 19. The square notch 15 is located at the square rod 20. The tapered rod 18 can reduce the resistance when the telescopic rod 5 enters the soil, and the cylindrical rod 19 can increase the resistance when the telescopic rod 5 moves up and down, thereby making the hollow tube 1 stable.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
