[0028] The limiting mechanism 7 includes a socket 701 opened on the side wall of the reel 13, and a fixed cover 702 is fixedly connected to the socket 701. The side wall of the fixed cover 702 is connected to a plurality of triangular blocks 703 arranged in an array through a telescopic mechanism 8, and the triangular block 703 includes an inclined surface 704 and a limiting surface 705. When winding, one end of the cable is inserted into the socket 701 and slides along the inclined surface 704, thereby pushing the triangular block 703 to slide into the fixed cover 702. After being inserted into place, under the action of the telescopic mechanism 8, the triangular block 703 is abutted against the cable and clamped and limited.

[0029] The telescopic mechanism 8 includes a strip opening 801 opened on the side wall of the fixed cover 702, and a sliding plate 802 is slidably connected in the fixed cover 702, a third spring 803 is fixedly connected between the sliding plate 802 and the fixed cover 702, and the triangular block 703 is inserted in the strip opening 801 and fixed to the side wall of the sliding plate 802, and the movement of the sliding plate 802 is pushed by the pushing mechanism 9, which guides and resets the movement of the triangular block 703.

[0032] Working principle: When in use, when winding up, insert one end of the cable into the jack 701, and at the same time, slide along the inclined surface 704, thereby pushing the triangular block 703 to slide into the fixed cover 702, and the third spring 803 is compressed. After being inserted into place, under the action of the third spring 803, the triangular block 703 is abutted against the cable and clamped and limited. Next, the motor 17 is started. The rotation of the motor 17 drives the driving shaft 18 and the L-shaped plate 22 to rotate, thereby driving the block 24 to rotate through the adjusting mechanism 3 and the squeezing mechanism 2, and then driving the slot 21 and the connecting shaft 19 to rotate. The rotation of the connecting shaft 19 drives the rotation of the rotating rod 12 and the reel 13, so that the cable can be reeled and recovered. When the traction force is large, the block 24 slides out of the slot 21 and slides on the side wall of the fixing ring 20.

At this time, the distance sensor 403 detects the distance change of the sensing block 401 and alarms and stops the motor 17, which is safer and more reliable. By rotating the rocking wheel 305, the rotation of the rocking wheel 305 drives the rotation of the threaded rod 304, drives the threaded tube 303 and the sleeve 302 to move up and down, and drives the moving block 23 to move up and down through the connecting block 306, so as to adjust the deformation of the first spring 202. At the same time, by observing the scale mark 502, the squeezing force between the clamping block 24 and the clamping slot 21 can be determined, and then the pulling force of the cable can be adjusted and controlled, so that the pulling force can be adjusted and controlled according to the specifications of the cable, which has stronger applicability and better use effect. After the cable on the reel 13 is wound up, the movable plate 14 is pushed to move in the direction close to the connecting plate 601. At the same time, the second spring 603 is compressed, so that the movable plate 14 is separated from the rotating rod 12. Then, the reel 13 with the cable wound around it can be removed from the rotating rod 12. Then, another reel 13 is sleeved on the side wall of the rotating rod 12. At the same time, the guide bar 1002 slides along the guide groove 1001. Finally, the movable plate 14 is released. Under the action of the second spring 603, the movable plate 14 moves in the direction close to the reel 13, and the rotating rod 12 is inserted into the mounting hole 15 for support and limit, so as to facilitate the replacement of the reel 13. This reciprocating process makes it easier for multiple reels 13 to retract and release the cable, which is more convenient, faster and more efficient to use. When the cable needs to be removed from the reel 13, the sliding plate 802 and the triangular block 703 are pushed into the fixed cover 702 by the pushing plate 902. At the same time, the third spring 803 is compressed and the triangular block 703 is separated from the cable. The end of the cable can be removed from the socket 701, which makes it easy to connect and remove the end of the cable from the reel 13, thereby facilitating the winding and removal of the cable, making it more convenient and quick to use.
