[0022] The present utility model will be further described below with reference to the drawings and embodiments:

[0023] A quick-release anti-fracture inverted conical bolt, see Figures 1 to 4, including an inverted cone bolt body 1, an outer seal ring 2 is sleeved on the inverted cone bolt body 1, and an auxiliary structure 3 is arranged inside the seal ring 2;

[0024] The auxiliary structure 3 includes a groove frame 301. A group of limiting grooves 302 are symmetrically opened on both sides inside the groove frame 301. A group of pressing blocks 303 are symmetrically engaged inside the group of limiting grooves 302. Among them, the pressing blocks 303 form an engaging and sliding structure with the groove frame 301 through the limiting grooves 302, and the groove frame 301 and the limiting grooves 302 are integrally formed. A clamping rod 304 is fitted and engaged inside the middle of the groove frame 301. A group of springs 305 are symmetrically arranged on both sides inside the clamping rod 304. One end of the spring 305 close to the opening is connected with a limiting block 306. Further, the limiting block 306 forms an elastic structure with the clamping rod 304 through the spring 305. When the clamping rod 304 is inserted into the inside of the groove frame 301, a part of the limiting block 306 is inserted into the limiting groove 302. In the utility model, the seal ring 2 is cut and removed to expose the pressing block 303, and the pressing block 303 is pressed inward so that the limiting block 306 at the end of the pressing block 303 moves out of the inside of the limiting groove 302. At this time, the clamping rod 304 is not restricted and can be directly pulled out of the groove frame 301, so as to realize the rapid separation between the threaded section 101 and the connecting section 102, facilitate the separation of the damaged part from the intact part, recycle the intact part according to requirements, and reduce waste.

[0025] It should be noted that the inverted cone bolt body 1 includes a threaded section 101, the threaded section 101 is arranged at the top of the auxiliary structure 3, a connecting section 102 is fixedly connected to the bottom of the auxiliary structure 3, and a number of counterbores 103 are evenly distributed on the surface of the connecting section 102. Among them, the groove frame 301 and the connecting section 102 are fixedly connected, and the counterbores 103 are annularly and equidistantly distributed on the surface of the connecting section 102. A reduced-diameter section 104 is fixedly connected to the lower end of the connecting section 102. Further, the clamping rod 304 and the threaded section 101 are fixedly connected. The clamping rod 304 penetrates through the inside of the groove frame 301 and enters the connecting section 102 and the reduced-diameter section 104. A number of slot holes 105 are evenly distributed on the surface of the reduced-diameter section 104. In the utility model, the arrangement of the counterbores 103 and the slot holes 105 effectively enables the curing agent to enter the counterbores 103 and the slot holes 105, which is convenient for increasing the contact area between the curing agent and the connecting section 102 and the reduced-diameter section 104, improving the bonding strength between the inverted cone bolt body 1 and the drill hole, and the arrangement of the clamping rod 304 extending into the connecting section 102 and the reduced-diameter section 104 can improve the strength of the connection part and reduce the possibility of the connection part breaking.

[0026] Working principle: Drill a hole in the wall and clean the residue in the hole. Then, squeeze the curing agent into the hole, and insert the reduced-diameter section 104 and the connecting section 102 into the drilled hole. The arrangement of the counterbore 103 and the groove hole 105 enables the curing agent to enter the counterbore 103 and the groove hole 105, increasing the contact area between the curing agent and the connecting section 102 and the reduced-diameter section 104, and improving the bonding strength between the inverted cone bolt body 1 and the drilled hole. The setting that the clamping rod 304 extends into the connecting section 102 and the reduced-diameter section 104 can improve the strength of the connection and reduce the possibility of fracture at the connection. After the inverted cone bolt body 1 is removed subsequently, cut and remove the sealing ring 2 to expose the pressing block 303. Squeeze the pressing block 303 inward so that the limiting block 306 at the end of the pressing block 303 moves out of the inside of the limiting groove 302. At this time, the clamping rod 304 is not restricted and can be directly withdrawn from the groove frame 301, thereby realizing the rapid separation between the threaded section 101 and the connecting section 102, separating the damaged part from the intact part, and recycling the intact part according to requirements, reducing waste.
