[0026] Please refer to Figures 1-7, a recyclable anchor structure provided in this embodiment includes: an end cone 1, a hollow rod 4, a telescopic rod 3, a sliding assembly 2, a movable tip 5, and a limit retaining ring 6. A cover plate 7 and an end cone 1 are respectively installed at both ends of the hollow rod 4. Specifically, the cover plate is fixedly connected to the hollow rod through a connecting cylinder 72. The surface of the connecting cylinder 72 is provided with external threads, and the connecting cylinder 72 is threadedly connected to the inner wall of the hollow rod through the external threads. The connecting cylinder 72 is a structure with a hollow interior and openings at both ends, facilitating a part of the telescopic rod to pass through the connecting cylinder 72 and then insert into the hollow rod; the cover plate is pressed against the end of the hollow rod through a fixing nut 8 and a gasket 71. The fixing nut 8 is threadedly connected to the connecting cylinder 72. The gasket 71 is arranged between the cover plate and the fixing nut 8 and sleeved on the outside of the connecting cylinder 72. The cover plate is sleeved on the outside of the connecting cylinder 72. The inner diameter of the connecting cylinder 72 for the telescopic rod to pass through is smaller than the outer diameter of the limit retaining ring, so as to be able to prevent the telescopic rod from detaching from the hollow rod. The sliding assembly 2 is installed on the telescopic rod 3. The telescopic rod 3 is slidably arranged in the hollow rod 4. By pushing or pulling the telescopic rod 3, the sliding assembly 2 can be driven to make the movable tip 5 slidably arranged on the sliding assembly 2 extend out of the movable hole 41 on the hollow rod 4. The movable tip 5 pierces into the rock mass to fix the anchor, or retracts into the cavity of the hollow rod 4; a limit retaining ring 6 is installed on the part of the telescopic rod 3 inserted into the hollow rod 4 to limit the stretching displacement of the telescopic rod 3, so that the telescopic rod 3 cannot detach from the hollow rod 4; the end cone 1 is installed at the end of the hollow rod 4 through threaded connection. The end of the end cone 1 is conical, facilitating insertion into the soil. A square-section connecting section 13 with a length of 100 mm is arranged between the cone and the hollow rod 4. Therefore, the end cone 1 is composed of a connecting section 13, a square section 12, and a conical section 11. The outer surface of the connecting section 13 is provided with external threads, facilitating the installation and disassembly of the end cone 1; the connecting section 13 is provided with holes adapted to the diameter of the telescopic rod 3, facilitating the telescopic rod 3 to have sufficient movement space when sliding in the hollow rod 4; both ends of the hollow rod 4 are respectively threadedly connected to the end cone 1 and the cover plate 7. The hollow rod 4 is equidistantly arranged with movable holes 41 along the length direction. Four movable holes 41 are circumferentially and evenly arranged at the same cross-sectional position where each movable hole 41 is arranged. The number of movable tips 5 corresponds to the number of movable holes 41, and the number of sliding assemblies 2 corresponds to the equidistantly distributed movable holes 41 on the hollow rod 4 (that is, multiple movable holes 41 at the same cross-sectional position correspond to one sliding assembly 2). Four movable tips 5 are slidably connected to each sliding assembly 2, and the four movable tips 5 are evenly arranged around the sliding assembly 2, thus corresponding to the four movable holes 41 at the same position; one end of the telescopic rod 3 extends into the hole of the end cone 1, and the other end passes through the cover plate 7, facilitating external control of the telescopic rod 3 to slide in the hollow rod 4.

The four sliding grooves are evenly distributed around the socket block 21; both ends of the groove of the sliding groove extend along both ends of the socket block 21, and the distance between the grooves of the sliding groove and the center of the socket block 21 gradually increases. One end of the sliding groove is closed, and the other end of the sliding groove is open. A baffle 24 is fixedly connected to the socket block 21 through a connecting screw 25 to close the opening of the sliding groove, and the movable tip 5 is slidably connected to the sliding groove.

[0028] The movable tip 5 is slidably connected to the sliding groove through a sliding member. The sliding member includes a connecting member 23, and two rollers 22 are installed on the connecting member 23. By rolling the rollers 22 on the sliding groove, since the groove gradually increases relative to the center of the socket block 21, during the process of the movable tip 5 sliding in the sliding groove along with the connecting member 23, the movable tip 5 moves away from or close to the socket block 21, realizing longitudinal expansion and contraction relative to the telescopic rod 3, so that it can extend out of the hollow rod 4 from the movable hole 41 of the hollow rod 4 or retract from the outside into the hollow rod 4; the baffle 24 closes the opening of the sliding groove to prevent the rollers 22 from derailing; the movable tip 5 is fixed to the connecting member 23 through a second connecting screw 51. To ensure firm fixation, a pair of second connecting screws 51 should be symmetrically arranged; the end of the movable tip 5 extending out of the hollow rod 4 is a cone, and the middle part is a cylinder. To ensure the vertical expansion and contraction of the movable tip 5 in the longitudinal direction, the hole of the hollow rod 4 needs to be adapted to the diameter of the movable tip 5, and the length of the cylinder should not be too short; the limit retaining ring 6 is fixed to the telescopic rod 3 by welding, and the installation position is inside the hollow rod 4, which can limit the maximum displacement of the telescopic rod 3 during the stretching process.

[0029] The installation, recovery and disassembly process of the anchor structure is as follows: insert the anchor structure into the adapted soil hole, stretch the end of the telescopic rod 3, drive the sliding component 2 to make the movable tip 5 extend out of the hollow rod 4 and pierce into the soil. Determine the stretching displacement according to the soil quality of the soil, keep the pulling force unchanged for a period of time, and then tighten the nut at the end of the anchor to complete the installation; when recovery and disassembly are required, push the stretching rod in the opposite direction to make the movable tip 5 retract into the cavity of the hollow rod 4, and then the anchor can be pulled out.

[0030] A recyclable anchor structure provided by this embodiment can drive the movable component in the hollow rod 4 by simply stretching the telescopic rod 3 in the anchor, so that the movable tip 5 extends out of the hole and pierces into the soil for anchoring; when recovery and disassembly are required, push the telescopic rod 3 in the opposite direction to make the movable tip 5 retract into the cavity of the hollow rod 4, and then the anchor can be pulled out. The operation is simple, and the anchor is not easily damaged during the installation and disassembly process, and the anchor can be recycled multiple times.
