A tightening plate 7 with a U-shaped structure is arranged on one side surface of the wire group mounting seat 2. The tightening plate 7 is snap-fitted with the wire group mounting seat 2. A fixing plate 11 is installed at the four corners of the surface of the tightening plate 7. The through holes provided on the surfaces of the three fixing plates 11 are all plugged with sliding rods 12. One end of the sliding rod 12 passes through the fixing plate 11 and is connected to the fixing block 3. A screw rod 13 is threadedly connected in the threaded hole provided on the surface of the other fixing plate 11. One end of the screw rod 13 passes through the fixing plate 11 and is rotatably connected to the fixing block 3. By setting the clamping assembly, the wire is wound on the surface of the winding seat 5. By rotating the screw rod 13, the tightening plate 7 is driven to squeeze the ferrule 10 provided in the wire group mounting seat 2, and the ferrule 10 is sleeved on the outside of the winding seat 5, so as to facilitate the reinforcement of the wire memory and avoid the situation of falling off. The wire can be uniformly reinforced to improve the installation efficiency.
