A storage groove 10 is opened inside the protective shell 1, and an extrusion port 11 is opened through the storage groove 10. By rotating the gear ring 2 inside the protective shell 1, the gear ring 2 drives the gear 6 to rotate The four threaded rods 7 are arranged in a circular array on the outer wall of the gear ring 2. The four threaded rods 7 are engaged with the gear ring 2 through the gear 6, so that the extrusion ring 9 can move up and down inside the storage groove 10, so that the extrusion ring 9 can extrude the fireproof plugging material stored in the storage groove 10 from the inside of the extrusion port 11, so that the fireproof plugging material enters the interior of the protective shell 1 to seal the cable, and the fireproof plugging box and the cable are tightly sealed, so as to effectively protect the cable and prevent the flame from spreading in the gap between the cable and the flame retardant material.

[0024] Reference Figure 2 The top of the gear ring 2 is fixedly connected with a connecting column 3, and the end of the connecting column 3 away from the gear ring 2 is fixedly connected with a handle 4. An arc groove 5 is opened on the top of the protective shell 1. The connecting column 3 is driven by the handle 4 to make the gear ring 2 rotate inside the protective shell 1, so that the gear ring 2 can effectively drive the gear 6 to rotate. The arc groove 5 opened on the top of the protective shell 1 can limit the connecting column 3, so that the connecting column 3 can drive the gear ring 2 to move along the arc groove 5.

[0025] Reference Figure 1 、 Figure 2 and Figure 4The outer wall of the protective shell 1 is fixedly connected with a fixing ring 12, and a fixing hole 13 is opened on the outer wall of the fixing ring 12.
