While the first fixing plate 2 and the second fixing plate 3 protect the positioning hole 103, the first fixing plate 2 and the second fixing plate 3 are connected by the limiting column 4 to avoid the first fixing plate 2 rotating relative to the second fixing plate 3 during use, thereby ensuring stability during use.

[0034] like Figure 1 , 3 As shown, a connecting piece 202 is provided on the outer side of the first fixing plate 2, and the connecting piece 202 is adapted to the second groove 104. A plurality of through holes 201 are opened on the outer side of the first fixing plate 2, and the through holes 201 penetrate the connecting piece 202, and the through holes 201 correspond to the limiting holes 102. A threaded ring is provided on the outer side of the connecting piece 202, and the shape of the connecting piece 202 is the same as that of the second groove 104. When in use, the connecting piece 202 cooperates with the second groove 104 to provide support for the first fixing plate 2, avoid the formation of a cavity between the first fixing plate 2 and the fixing plate 1, and then cause the first fixing plate 2 to deform when subjected to force, thereby ensuring stability during use.

[0035] like Figure 3As shown, the second fixing plate 3 is adapted to the first groove 101, a connecting tube 301 is provided on the outside of the second fixing plate 3, a threaded groove 302 is provided inside the connecting tube 301, and the threaded groove 302 is connected to the threaded ring, the first fixing plate 2, the connecting plate 202, the connecting tube 301 and the second fixing plate 3 can be made of wear-resistant and impact-resistant materials such as high manganese steel, alloy steel or high chromium alloy, which can protect the positioning hole 103 while ensuring the structural strength during use. The shape of the second fixing plate 3 can be cylindrical, hexagonal or quadrangular or imitation shape, wherein the imitation shape means that, for example, if the first groove 101 is a cylindrical groove, the second fixing plate 3 is a cylindrical groove similar to the cylindrical groove. If the first groove 101 is a hexagonal prism groove, the second fixing plate 3 is a hexagonal prism similar to the hexagonal prism groove. No more examples are given here. When the second fixing plate 3 is non-cylindrical, the second fixing plate 3 cooperates with the first groove 101 to limit the connecting tube 301 to prevent the connecting tube 301 from rotating relative to the connecting plate 202 during use, thereby ensuring stability during use. When in use, the connecting plate 202 is connected to the connecting tube 301 through the cooperation of the threaded ring and the threaded groove 302, thereby shielding and protecting the positioning hole 103 to prevent the pin from directly contacting the positioning hole 103 during use and causing damage to the positioning hole 103, thereby extending the service life of the positioning hole 103.

[0037] like Figure 3 , 4As shown in FIGS. 5 and 7 , the telescopic member 6 moves inside the sliding hole 403, a first spring 601 is provided on the outside of the telescopic member 6, a plurality of limit grooves 602 are provided on the outside of the telescopic member 6, and the limit grooves 602 correspond to the rotating rod 401. The telescopic member 6 has the same shape as the through hole 201. After the connecting piece 202 is connected to the connecting tube 301, the telescopic member 6 is inserted into the connecting piece 202 under the push of the first spring 601, so that the connecting piece 202 is moved under the cooperation of the telescopic member 6 and the through hole 201. The limit is used to prevent the connecting piece 202 from rotating relative to the connecting tube 301 during use, thereby ensuring stability during use. When the connecting piece 202 needs to be disassembled, the telescopic part 6 inside the through hole 201 is first pressed to connect the rotating rod 401 with the limiting groove 602 on the outside of the telescopic part 6, so that the rotating rod 401 limits the telescopic part 6 to prevent the telescopic part 6 from being inserted into the connecting piece 202, thereby releasing the limit on the connecting piece 202 and facilitating the disassembly of the connecting piece 202.

[0038] like Figure 4 , 6As shown, the sliding assembly 5 includes a plurality of sliding members 501, the sliding members 501 correspond to the guide grooves 402, and the sliding members 501 slide inside the guide grooves 402, and the sliding members 501 are provided with second springs 505 on the outside, and the sliding members 501 are provided with rotation grooves 502 on the opposite sides, and the rotation grooves 502 are provided with fixed platforms 504 inside, and the fixed platforms 504 on one side are provided with a rotation shaft on the outside, and the baffle plate 503 is provided on the outside of the rotation shaft, and a torsion spring is provided inside the rotation shaft. After the shrinking member 6 is limited, the connecting piece 202 and the connecting tube 301 are first rotated relatively to each other, so that the connecting piece 202 is separated from the connecting tube 301. At the same time when the connecting piece 202 is separated from the connecting tube 301, the sliding member 501 slides out from the inside of the limiting column 4 under the push of the second spring 505. At the same time when the sliding member 501 slides, the rotating rod 401 pushes the baffle 503 to rotate around the rotating axis as the center of the circle to avoid interference between the baffle 503 and the rotating rod 401. When the separation is completed, the sliding member 501 drives the baffle 503 away from the rotating rod 401 under the push of the second spring 505, and drives the baffle 503 to rotate and reset under the action of the torsion spring inside the rotating shaft, waiting for reinstallation. When it is necessary to connect the connecting piece 202 and the connecting tube 301, the first fixed plate 2 is first rotated so that the connecting piece 202 moves relative to the connecting tube 301 under the cooperation of the threaded ring and the threaded groove 302. When the connecting piece 202 moves, the sliding member 501 extending out of the outer side of the limiting column 4 is squeezed. When the baffle 503 contacts the rotating rod 401, due to the obstruction of the fixed platform 504, the baffle 503 pushes the rotating rod 401 to rotate with the torsion spring rod as the center, thereby releasing the limit of the telescopic member 6, so that the telescopic member 6 is inserted into the through hole 201 under the push of the first spring 601, thereby completing the limit of the connecting piece 202, avoiding the connecting piece 202 from rotating relative to the connecting tube 301 during use, and ensuring stability during use.
