Further, the lower end of the rectangular block 503 is fixedly connected with a second connecting rod 504, the other end of the second connecting rod 504 is rotatably connected with a connecting sleeve 505, the other end of the connecting sleeve 505 is fixedly connected with a tapered pushing part 506, the height of the first side hollow-out groove 404 is greater than the sum of the length of the triangular positioning anti-slip plate 509 and the height of the tapered pushing part 506, and the triangular positioning anti-slip plate 509 can rotate out through the second side hollow-out groove 508 and the first side hollow-out groove 404 under normal conditions, so that the height of the first side hollow-out groove 404 is greater than the length of the triangular positioning anti-slip plate 509; when the screwed pipe portion 501 is outward, the rectangular block 503 and the internal structure thereof are outward synchronously, the triangular positioning anti-slip plate 509 itself enters the pre-drilled hole and then is reset and unfolded outward, the triangular positioning anti-slip plate supports against the inner wall of the hole, when the rectangular block 503 moves outward, the triangular positioning anti-slip plate 509 can be gradually unfolded and clamped in the hole, the hole is forced to be deformed and the upper end surface of the triangular positioning anti-slip plate 509 is extruded, namely, the distance that the triangular positioning anti-slip plate 509 moves is basically the same as that the conical pushing portion 506 moves, and therefore the sum of the length of the triangular positioning anti-slip plate 509 and the height of the conical pushing portion 506, which is larger than the first side hollow groove 404, can meet the normal working requirement. A positioning ladder-shaped part 507 is arranged in the cross direction outside the connecting sleeve 505 and the conical pushing part 506, the positioning ladder-shaped part 507 is fixed with the connecting sleeve 505 and the conical pushing part 506, an expansion groove 402 is formed in the cross direction outside the expansion pipe 4, an anti-cracking hole 403 is formed in the inner end of the outer side surface of the expansion pipe 4 along the first side hollow-out groove 404, the anti-cracking hole 403 and the first side hollow-out groove 404 are identical in thickness, and one end of the positioning ladder-shaped part 507 is located in the expansion groove 402.

Further, the inside of expansion pipe 4 is provided with cylindrical cavity 401, the one end fixedly connected with head rod 502 that second connecting rod 504 was kept away from to rectangular block 503, the other end fixedly connected with screwed pipe portion 501 of head rod 502, the upper end along expansion pipe 4 in the screwed pipe portion 501 outside is provided with big packing ring 3, the top in the screwed pipe portion 501 outside is provided with hexagon nut 1, hexagon nut 1 and screwed pipe portion 501 threaded connection, the screwed pipe portion 501 outside is provided with spring pad 2 along being provided with between big packing ring 3 and the hexagon nut 1, screwed pipe portion 501, head rod 502, rectangular block 503, second connecting rod 504 and connecting sleeve 505 all are located the inside of cylindrical cavity 401.

The working principle is as follows: when the expansion screw is used, a drill is used for punching a hole in a mounting surface, the whole expansion screw is placed in the punched hole, the conical pushing portion 506 faces inwards, the two triangular positioning anti-slip plates 509 in the rectangular block 503 extrude the pressure spring 510, and the triangular positioning anti-slip plates 509 shrink inwards without influencing the placement of the expansion screw. After the expansion pipe 4 is pressed, the hexagon nut 1 is rotated through a tool, the threaded pipe part 501 is rotated outwards due to the threaded connection relationship between the hexagon nut 1 and the threaded pipe part 501, the conical pushing part 506 slides outwards due to the rotation relationship between the second connecting rod 504 and the connecting sleeve 505, and the trapezoidal part 507 is positioned outside the conical pushing part 506 and outwards along the expansion groove 402; as the tapered pushing portion 506 moves into the expansion tube 4, the expansion tube 4 is expanded, and the expansion generates frictional gripping force, thereby achieving a fixing effect. When screwed pipe portion 501 is outwards, rectangular block 503 and its inner structure are outwards synchronous, triangle location antiskid ribbed tile 509 itself can reset and outwards expand after entering the hole of punching in advance, support in the hole inner wall, and when rectangular block 503 outwards removed, triangle location antiskid ribbed tile 509 can expand gradually, blocks in the hole, forces the hole internal deformation to extrude the up end of triangle location antiskid ribbed tile 509, makes the fixed of whole expansion screw and installation face inseparabler.
