[0033] Reference Figure 1 - Figure 3 On the basis of the above embodiment, in order to facilitate the fastening of hoop 3, the following design is given in this embodiment:

[0034] As a preferred embodiment, the fastening mechanism 4 includes first connecting block 401 and second connecting block 402, and the first connecting block 401 and the second connecting block 402 are fixedly installed on the surface of the both ends of the hoop 3, and the one side surface of the first connecting block 401 and the second connecting block 402 is respectively provided with first recess 403 and second recess 404. The inside of the first recess 403 is rotatably connected with rotating block 405, and the one side surface of the rotating block 405 is fixedly installed with first threaded rod 406, and the first threaded rod 406 is arranged in the second recess 404. The outside of the first threaded rod 406 is threadedly connected with extrusion block 407, and the upper surface of the extrusion block 407 is fixedly installed with two protrusions 408.

[0035] In the embodiment, the fastening mechanism 4 mainly consists of a first connecting block 401 and a second connecting block 402, which are respectively installed on the surfaces at both ends of the hoop 3. On one side of the first connecting block 401 and the second connecting block 402, a first recess 403 and a second recess 404 are opened, which provide convenience for subsequent fastening operation. The first recess 403 is rotatably connected with a rotating block 405, and one side of the rotating block 405 is fixedly installed with a first threaded rod 406, which is arranged in the second recess 404. In order to achieve the fastening of the hoop 3, an extrusion block 407 is threadedly connected outside the first threaded rod 406, and the upper surface of the extrusion block 407 is further fixedly installed with two convex blocks 408 for facilitating rotation operation. By simply rotating the convex blocks 408, the extrusion block 407 can be driven to move along the first threaded rod 406, thereby achieving effective fastening of the hoop 3.

[0036] Reference Figure 1 - Figure 4 On the basis of the above embodiment, in order to be able to connect the hoops 3 on both sides and prevent them from falling off, the following design is given in the embodiment:

[0037] As a preferred embodiment, the connecting mechanism 5 comprises a mounting block 501, and two mounting blocks 501 are fixedly installed on the surfaces at both sides of the hoop 3. A connecting hole 502 is opened in the middle of the mounting block 501, and a second threaded rod 503 is arranged inside the connecting hole 502. A fixed block 504 is fixedly installed on one end surface of the second threaded rod 503. A nut 505 is threadedly connected outside the second threaded rod 503, and the nut 505 is arranged on one side of the hoop 3 on the other side.

[0038] In the embodiment, the connecting mechanism 5 mainly consists of a mounting block 501, which is fixedly installed on the surfaces at both sides of the hoop 3, and a connecting hole 502 is opened in the middle of each mounting block 501. Through these connecting holes 502, a second threaded rod 503 is introduced, one end surface of which is fixedly installed with a fixed block 504 for facilitating blocking on one side. A nut 505 is threadedly connected outside the second threaded rod 503, and the nut 505 is arranged on one side of the hoop 3 on the other side, so that the user can rotate the nut 505 to make it move along the second threaded rod 503 and gradually approach the hoop 3 on the other side, and finally achieve the close connection of the hoops 3 on both sides, avoiding the connection with iron wire, which is inconvenient to operate and easy to cause harm to personnel.

[0039] The pipeline connection anti - off device core component is the connecting piece 1, both ends of which are tightly sleeved with the connecting pipeline 2, ensuring the precise butt joint between the pipelines. In order to reinforce the connection, a firm hoop 3 is additionally arranged outside, forming an additional protective barrier. The innovative fastening mechanism 4 design on the hoop 3 greatly facilitates the user to adjust the tightness. The mechanism is composed of a first connecting block 401 and a second connecting block 402, which are respectively fixed at both ends of the hoop and are provided with a first recess 403 and a second recess 404. Through the combination of the rotating block 405 and the first threaded rod 406, and the threaded connection of the extrusion block 407, the user only needs to rotate the convex block 408 to easily adjust the fastening degree of the hoop, which is efficient and safe.

[0040] In addition, in order to further strengthen the stability of the overall structure, a connecting mechanism 5 is ingeniously arranged between the two hoops 3. The mechanism is based on the mounting block 501, which is fixed on both sides of the hoop, and the connecting hole 502 is opened in the middle for the second threaded rod 503 to pass through. One end of the second threaded rod 503 is provided with a fixed block 504, and the other end is connected with the other side of the hoop through the nut 505. The user rotates the nut 505, so that it moves along the threaded rod until it tightly fits the other side of the hoop, thereby avoiding the need to rely on traditional wire connection, which simplifies the operation steps and avoids the safety hazards that may be caused by the wire.
