Specifically, the driving device of the abutting block 62 adopts a thread abutting device, the first end of the screw 621 is rotated to enable the second end of the screw 621 to be screwed into the threaded hole until the second end of the screw 621 abuts against the supporting plate 9, the first end of the screw 621 is continuously rotated, the screw 621 drives the abutting block 62 to be away from the supporting plate 9 under the action of a reaction force, the abutting block 62 abuts against the cable 8 until the cable abuts against the inner surface of the clamping piece 61, the thread abutting mode is low in cost, abutting is firm, and operation is simple.

According to the above-mentioned specific clamp 6 of the present embodiment, the key technical point is that the raceway arrangement 3 includes a mating surface 31 substantially orthogonal to the cable in contact with a clamp 6; drawing formula fire prevention subassembly loads in this when preventing hot wall body from one side, because fastener 61 is located the wire casing to buckle outstanding outer edge and the laminating of wire casing inner wall in fitting surface 31 on fastener 61, because the setting of fitting surface 31, the gap between fastener 61 top and wire casing 3 is cut off by this fitting surface 31, in order to avoid appearing the gap that link up and prevent hot wall between fastener 61 and drawing formula fire prevention subassembly's wire casing 3. In some embodiments, due to the arrangement of the clamping apparatus 6, when the drawing type fireproof assembly is filled into the fireproof wall and fireproof mud is injected into the wire casing 3, it is difficult to fully fill the gap above the clamping member 61. The abutting block 62 is opposite to the bending part of the clamping piece, the abutting block 62 abuts towards the clamping piece, a certain redundant space is formed above and below the abutting block 62 due to the fact that the diameter and the number of cables are uncertain, the wire groove 3 abuts against the abutting block 62 in the approaching direction, namely, the yielding space 32 is arranged above the abutting block 62, so that after the cables are jacked up by the abutting block 62, sufficient space is formed above the cables to give way to the cables, and the space is the yielding space 32. The both ends that support kicking block 62 are provided with the screw hole, and threaded hole is provided with screw 621, and guard plate 1 is equipped with the hole 33 of stepping down that matches with adjusting screw's instrument, sees easily that the hole 33 of stepping down is greater than the projected trompil of wire casing 3 on guard plate 1 to instrument such as spanner wrench twists screw 621.

Optionally, as shown in fig. 1, 2 and 7, a handle 7 is provided on the second end face of the fender 1.

Specifically, constructor can mention and place into corresponding installation space or pull out from the installation space with pull formula fire prevention subassembly through 7 pieces of handle, improves constructor work efficiency, and it is fire prevention subassembly holder harm constructor personal safety to have avoided dismouting in-process pull. Furthermore, considering that the large-size pull-type protective assembly has certain weight, two handles 7 can be arranged on the protective plate 1, and two persons can pull and pull in cooperation during disassembly and assembly; the form of the handle 7 is not particularly limited, and includes, but is not limited to, an outer insert handle 7, an inner insert handle 7, an embossed handle, a non-magnetic metal handle 7, and the like. In some embodiments, the handle 7 is designed as a movable snap switch that is fastened to an adjacent component (e.g., other pull-out fire protection component) on the fire wall, and the protection plate of the pull-out fire protection component is separated from the adjacent component by rotation, magnetic attraction, etc. so as to fix or detach the pull-out fire protection component.
