[0040] In this embodiment, the magnetic blocks 212 are symmetrically installed at the positions where the two slide grooves 25 are located below the fixed plate 21 , so that when the slide shaft 22 contacts the magnetic blocks 212 , the magnetic blocks 212 can adsorb and limit the slide shaft 22 .

[0041] Going further:

[0042] In an optional embodiment, a fixing block 27 is fixedly connected to the cover surface of the culvert body 1, a through groove A is opened inside the fixing block 27, and an insertion rod 28 is inserted into the through groove A. The interior of the culvert body 1 is rotatably connected to a positioning plate 26 via a rotating shaft, a through groove B is opened inside the positioning plate 26, and the insertion rod 28 is inserted into the through groove B, and the through groove B consists of a rectangular structural groove and a cylindrical structural groove.

[0043] In this embodiment: a fixing block 27 is installed on the cover plate surface of the culvert body 1, and the insertion rod 28 passes through the fixing block 27 through the through groove A. The positioning plate 26 is rotatably installed inside the culvert body 1 by rotating the shaft, and a through groove B is opened inside the positioning plate 26, so that the insertion rod 28 passes through the through groove B to penetrate the positioning plate 26, thereby realizing the limitation of the positioning plate 26.

[0044] Going further:

[0045] In an optional embodiment, the surface of the insertion rod 28 is symmetrically connected to two limit rods 29 through a mounting seat A, and the end of the limit rod 29 away from the insertion rod 28 is rotatably connected to a positioning rod 210 through a mounting seat B. The interior of the insertion rod 28 is symmetrically provided with two sockets, and the interiors of the two positioning rods 210 are inserted into the interiors of their sockets. A first spring 211 is installed inside the sockets, and both ends of the first spring 211 are in contact with the insertion rod 28 and the positioning rod 210.

[0050] The auxiliary component 3 includes a positioning block 31 rotatably connected to the surface of the insertion rod 28, and a second spring 32 is sleeved on the surface of the insertion rod 28. The two ends of the second spring 32 are respectively fitted with the positioning block 31 and the fixed block 27. The side of the fixed block 27 away from the second spring 32 is rotatably connected to a protective cover 33 through a mounting seat C.

[0051] The second spring 32 is then released to push the rod 28 back to its original position, and the protective cover 33 is installed on the side away from the second spring 32 through the mounting seat C, so that the protective cover 33 covers the position of the rod 28 to prevent accidental touch.

[0052] The working principle and use process of the utility model are as follows: the operator fixes the two fixing plates 21 on the inner wall of the supporting wall of the culvert body 1 by bolts, inserts the two ends of the positioning shaft 23 connected to the protective net body 24 into the inside of the two fixing plates 21, and symmetrically opens two slide grooves 25 on the inner wall of the culvert body 1, so that the two ends of the sliding shaft 22 connected to the protective net body 24 are inserted into the inside of the two slide grooves 25, so that the sliding shaft 22 rotates with the positioning shaft 23 as the axis through the protective net body 24, so as to change the shape and position of the protective net body 24 in different environments, and symmetrically installs magnetic blocks at the positions where the two slide grooves 25 are located below the fixing plates 21 212, when the sliding shaft 22 contacts the magnetic block 212, the magnetic block 212 is attracted and limited, a fixing block 27 is installed on the cover plate surface of the culvert body 1, and the insertion rod 28 passes through the fixing block 27 through the through groove A, and the positioning plate 26 is installed inside the culvert body 1 by rotating the rotating shaft, and a through groove B is opened inside the positioning plate 26, so that the insertion rod 28 passes through the through groove B to penetrate the positioning plate 26, so as to limit the positioning plate 26, and the insertion rod 28 is symmetrically rotated through the mounting seat A to connect the two limiting rods 29, and the end of the limiting rod 29 away from the insertion rod 28 is rotated through the mounting seat B to be connected with the positioning rod 210, and the surface of the insertion rod 28 is located between the two positioning rods. Two sockets are symmetrically provided at the position of the rod 210, and a first spring 211 is placed inside each socket. Then, the positioning rod 210 is inserted into the inside of the socket and fits with the first spring 211, so that when the limiting rod 29 passes through the positioning plate 26 along with the insertion rod 28, the positioning rod 210 is lifted up by the first spring 211, so that the limiting rod 29 rotatably connected to the positioning rod 210 through the mounting seat B rotates inside the mounting seat A, and supports the positioning plate 26 to limit it. After the insertion rod 28 passes through the fixing block 27, a second spring 32 is sleeved on the surface of the insertion rod 28, so that one end of the second spring 32 fits with the fixing block 27, and then the surface of the insertion rod 28 is fixed. The face sleeve sets the positioning block 31, so that the positioning block 31 is rotatably connected with the insertion rod 28 through the bearing, so that the insertion rod 28 is pulled in the direction of the fixed block 27, and rotates while pulling, so that the insertion rod 28 is rotated ninety degrees, so that the limiting rod 29 corresponds to the rectangular groove part of the through groove B opened in the positioning plate 26, and the insertion rod 28 can be pulled out from the inside of the positioning plate 26, thereby releasing the limit on the positioning plate 26. After the insertion rod 28 is released, the second spring 32 will push the insertion rod 28 back to its original position, which is convenient for the next use. The protective cover 33 is installed on the side away from the second spring 32 through the mounting seat C, so that the protective cover 33 covers the position of the insertion rod 28 to prevent someone from touching it by mistake.
