After the cable enters, it will pass through the inside of the cross groove 404. At this time, the sponge ring 403 contacts the surface of the cable, providing a certain cleaning function to its surface. The cable is gradually pulled through the support frame 304 on the same horizontal line in turn. When passing through the support frame 304, the operator manually pulls the slide bar 305 upwards, and the spring 307 is immediately compressed until the clamping plate 306 moves upward inside the support frame 304 to facilitate the cable to pass through. After the cable passes through, just release the slide bar 305, and the clamping plate 306 fixes the cable. When the cable passes through from the other end After the wire hole 2 is passed through, the distance between the multiple groups of moving blocks 302 is adjusted, and the fixing force provided to any end of the cable can be increased. When the length of the cable is long, the cable is hung on the hanging rod 308, and the slide bar 305 is manually rotated. The slide bar 305 can drive the rotating shaft 303 to rotate, so that the cable is rolled up. When the cable is rolled up to the appropriate length, the limit rod 312 is inserted into the fixing hole 311 and the positioning hole 309 in turn to fix the rotating shaft 303 to prevent the cable from detaching after being rolled up. When the sponge ring 403 is used for a long time and the surface is attached with dirt, the magnetic ring 402 is pulled outward to make it detached from the mounting groove 401, so that the sponge ring 403 can be cleaned conveniently to ensure the subsequent cleaning effect of the cable.
