Through the interaction between the rotating member 301 and the stabilizing member 302, and the action of the rotating member 301 on the fixing member 202, when the flame retardant member 204 completes the placement of the flame retardant and fireproof material, it can further push the material under the action of the adjusting member 203, and make various materials contact to better protect the cable at the incoming line port.

[0048] Specifically, the rotating member 301 includes a locking groove 301a, a threaded rod 301b, a rotating ring 301c and a rotating pattern 301d. The locking groove 301a is arranged on the adjusting rod 202a. The locking groove 301a is opened at the upper side of the adjusting rod 202a. The opening of the locking groove 301a makes the adjusting rod 202a have a "U"-shaped notch, which is convenient for rotating the object on the adjusting rod 202a. The threaded rod 301b is arranged on the locking groove 301a. The threaded rod 301b is fixedly connected to the locking groove 301a, and the threaded rod 301b is fixedly connected to a part of the adjusting rod 202a. The rotating ring 301c is arranged on the threaded rod 301b, the rotating ring 301c is rotatably connected to the threaded rod 301b, the diameter of the rotating ring 301c is larger than that of the threaded rod 301b, and the rotating ring 301c can be adapted to the threaded rod 301b, and when the rotating ring 301c is rotated, it can be rotated on the threaded rod 301b to achieve movement, the rotating pattern 301d is set on the rotating ring 301c, the rotating pattern 301d is opened on the rotating ring 301c, and the rotating pattern 301d is only on a part of the rotating ring 301c, the rotating pattern 301d makes the outer surface of the rotating ring 301c have uneven grooves, which makes the rotating ring 301c can be rotated more conveniently.

[0049] Furthermore, the stabilizing member 302 includes a transition groove 302a, a buckle block 302b and a buckle groove 302c. The transition groove 302a is arranged on the rotating ring 301c. The transition groove 302a is opened on the rotating ring 301c, and the rotation pattern 301d is opened on the outer surface of the rotating ring 301c.

The buckle block 302b is movably connected to the rotating groove to attach Figure 6Taking the reference block 302b as an example, the front view of the reference block 302b is the shape of a reversed "凵" rotated 90 degrees counterclockwise, the top view is the shape of a "7", and the left view is composed of the shape of an "L". One side of the longer "丨" structure in the left view is connected to the transition groove 302a, and one side of the shorter "丨" structure in the front view is connected to the adjusting rod 202a. In this way, the rotation of the rotating ring 301c will not cause the reference block 302b to rotate together, but the displacement of the rotating ring 301c will drive the reference block 302b together. The reference groove 302c is arranged on the adjusting rod 202a. The reference groove 302c is opened on the adjusting rod 202a. The reference groove 302c is opened on the upper side of the sliding groove 203a, and their positions do not interfere with each other. The reference groove 302c is adapted to the movement of the reference block 302b on the adjusting rod 202a. When the reference block 302b is displaced, the longer "丨" structure in the left view can push the adjusting plate 203b to move on the adjusting rod 202a. Such continuous pushing can make the flame retardant material closely contact under the action of the adjusting rod 202a and the fixing plate 202c, effectively preventing the combustion of the flame, improving the fire prevention performance and flame retardant performance of the cable, blocking the fire source outside, with high safety performance and improved practicability.

[0050] The remaining structures are the same as those in Embodiment 1.

[0051] Operation process: By rotating the rotation pattern 301d on the rotating ring 301c, the rotating ring 301c can be displaced along with the rotation on the threaded rod 301b, which also makes the reference block 302b perform a displacement synchronous with the rotating ring 301c under the action of the transition groove 302a and the reference groove 302c. Thus, the adjusting plate 203b can drive the magnesium oxide fireproof layer 204a, the flame retardant cloth layer 204b and the fireproof silica gel sheet to move towards the fixing plate 202c, making the magnesium oxide fireproof layer 204a, the flame retardant cloth layer 204b and the fireproof silica gel sheet closely contact with the adjusting plate 203b, and better protecting the cable at the inlet from fire.
