[0031] In this embodiment, please refer to Figure 4-5 A first rotating shaft 41 is fixedly connected to one side of the take-up roller 4, and one end of the first rotating shaft 41 protrudes from one side of the joint body 1. A counting component 42 is provided on the other side of the take-up roller 4. A wire fixing belt 43 is provided on the outer edge of the take-up roller 4, and a wire fixing hole for the cable body 3 to pass through is formed between the wire fixing belt 43 and the outer side of the take-up roller 4. The counting component 42 includes a linkage shaft 421 fixedly connected to one side of the take-up roller 4, and the other end of the linkage shaft 421 is fixedly connected to a first gear 422. A second gear 423 is meshed with the top of the first gear 422, and a first connecting shaft 424 that penetrates the second gear 423 is provided on one side of the second gear 423. A third gear 425 is provided at one end of a connecting shaft 424, and a small counting circle 426 is provided at the other end.

A large counting circle 429 is provided at one end of the second connecting shaft 428. In this embodiment, by passing the cable body 3 through the fixing belt 43 and clamping one end of the cable body 3, the first rotating shaft 41 is rotated to rotate the take-up roller 4, so that the cable body 3 can be rolled up. At the same time, when the take-up roller 4 rotates, the linkage shaft 421 rotates, and through mechanical coordination, the small counting circle 426 and the large counting circle 429 are rotated.

[0032] In this embodiment, please refer to Figure 6-7The dust cover 2 is provided with a transmission assembly 21 inside, an outer threading hole 22 for the cable body 3 to pass through is provided on the surface of the dust cover 2, a turntable 23 is movably connected to the outer side of the dust cover 2, and a plurality of first magnetic rings 231 are fixedly connected to the inner wall of the turntable 23, the transmission assembly 21 includes a transmission disk 211, a positioning groove 212 penetrating the transmission disk 211 is provided on the surface of the transmission disk 211, an inner threading hole 213 corresponding to the outer threading hole 22 for the cable body 3 to pass through is provided on the surface of the transmission assembly 21, and the transmission disk 21 1 is provided with a second magnetic circle 214 having the same number as the first magnetic circle 231 and attracting each other, and the corresponding surfaces of the first magnetic circle 231 and the second magnetic circle 214 attract each other, and the inner wall of the outer threading hole 22 is provided with a waterproof member 24. In this embodiment, the cable body 3 can pass through the outer threading hole 22 to penetrate into the interior of the connector body 1, and the turntable 23 is rotated by an external force. Through the mutual attraction between the first magnetic circle 231 and the second magnetic circle 214, the transmission disk 211 can be rotated, and the position of the positioning groove 212 can be changed.

[0033] In this embodiment, please refer to Figure 6-7 The waterproof part 24 includes a sealing ring 241, and a plurality of linkage frames 242 with the same spacing are provided on the outside of the sealing ring 241. One end of the linkage frame 242 is movably connected to the inner wall of the positioning groove 212. In this embodiment, when the transmission component 21 rotates, the position of the positioning groove 212 changes, and a thrust can be given to the linkage frame 242, so that the linkage frame 242 moves in the inner cavity of the positioning groove 212, thereby enlarging the inner diameter of the sealing ring 241.

[0034] In this embodiment, please refer to Figure 2-3 The top and bottom of the connector body 1 are both provided with protective compartments that are opened and closed by protective covers 17, and the rotating end of the second rotating shaft 51 is located in the protective compartment. In this embodiment, after the cable docking is completed, the protective compartment is closed by the protective cover 17 to prevent the second rotating shaft 51 from being exposed to the outside, to prevent the second rotating shaft 51 and its components from being damaged by wind and sun, and to enhance the dust and water resistance of the connector.

[0035] In this embodiment, please refer to Figure 1 , Figure 5 Counting ports 16 are respectively provided at both ends of the top of the connector body 1, and the small counting circle 426 and the large counting circle 429 are located in the inner cavity of the counting port 16. In this embodiment, when the numbers on the top of the small counting circle 426 and the large counting circle 429 rotate and change, the length of the cable being rolled up can be observed at any time through the counting port 16.

[0036] In this embodiment, please refer to Figure 5The time required for the third gear 425 to rotate one circle is one tenth of the time required for the fourth gear 427 to rotate one circle. In this embodiment, the third gear 425 rotates ten times faster than the fourth gear 427, so that the rotation speed of the small counting circle 426 it transmits is ten times that of the large counting circle 429, thereby completing the decimal conversion.

[0037] In this embodiment, please refer to Figure 6 One end of the linkage frame 242 is fixedly connected with an anti-drop cap 243, and the diameter of the anti-drop cap 243 should be larger than the minimum value of the inner diameter of the positioning groove 212. In this embodiment, by providing an anti-drop cap 243 at one end of the linkage frame 242, the linkage frame 242 can be prevented from detaching from the inner wall of the positioning groove 212 when moving.

[0038] In this embodiment, please refer to Figure 3 The cable body 3 includes an insulating sheath 31 and a conductor 32. The insulating sheath 31 is wrapped around the outside of the conductor 32, and one end of the conductor 32 protrudes from the insulating sheath 31. The two conductors 32 are fixed and tightened by a clamp 13. A conductor 131 is provided on the inner side of the clamp 13. In this embodiment, when the two ends of the cable are docked, if the conductor 32 is not completely docked, or in daily use, after the cable is moved backward, current transmission can still be maintained through the conductor 131.

[0039] In this embodiment, please refer to Figure 3 The telescopic rod 55 is composed of a rod body and a sleeve. A sliding groove is provided on the rod body along the length direction. A protruding slider is provided on the inner wall of the sleeve. The sleeve is sleeved on the rod body. The slider is engaged with the sliding groove. The sleeve and the rod body are in sliding cooperation. In this embodiment, the telescopic rod 55 can transmit torque and can be extended and retracted at the same time. The length changes as the threaded rod 56 moves up and down.

[0040] Working principle of the present invention:

[0041] Step 1: insert the two ends of the cable body 3 into the connector body 1, open the protective cover 17, and rotate the second shaft 51 to drive the main pulley 52 to rotate, and the main pulley 52 drives the two belt strips 53 to rotate, and the belt strip 53 drives the two secondary pulleys 54 to rotate, and the secondary pulley 54 drives the telescopic rod 55 to rotate, so that the threaded rod 56 rotates along the inner wall of the threaded groove 15. Since the inner wall of the threaded groove 15 is provided with a spiral groove adapted to the outer side of the threaded rod 56, the threaded rod 56 is controlled to rotate. It can be moved up and down along the inner wall of the thread groove 15, so that the two corresponding first clamping blocks 12, the clamping head 13, and the second clamping block 14 can be controlled to move toward each other, and the insulating skin 31 can be clamped, and the wire 32 can be docked and fixed in the inner cavity of the clamping head 13, so as to complete the docking of the cable body 3. At the same time, by rotating the second rotating shaft 51, the first clamping block 12, the clamping head 13, and the second clamping block 14 can be controlled to move forward and backward, so that the spacing between them becomes larger, and the cable body 3 can be taken out, and at the same time, a cable body 3 with a thicker size can also be docked;

[0042] Step 2, when the cable body 3 is too long and needs to be reeled up, the dust cover 2 is removed, the cable body 3 is passed through the threading hole of the wire fixing belt 43, and one end of the cable body 3 is clamped by the first clamping block 12, the clamping head 13, and the second clamping block 14. Then, the first rotating shaft 41 can be rotated to continuously reel up the cable body 3 on the outer side of the take-up roller 4. When the take-up roller 4 is reeling up the cable, the linkage shaft 421 is driven to rotate, and the rotation of the linkage shaft 421 drives the first gear 422 to rotate. Since the first gear 422 is meshed with the second gear 423, the first gear 422 drives the second gear 423 to rotate, and the second gear 423 drives the first linkage shaft 421 to rotate. The connecting shaft 424 drives the small counting circle 426 to rotate, so that the number on the top of the small counting circle 426 observed at the counting port 16 changes, and the rotation of the first connecting shaft 424 drives the third gear 425 to rotate at the same time. Since the third gear 425 and the fourth gear 427 are meshed with each other, when the third gear 425 rotates, the fourth gear 427 drives the second connecting shaft 428 to rotate, and the large counting circle 429 is driven to rotate through the rotation of the second connecting shaft 428, so that the value of the large counting circle 429 observed at the counting port 16 changes, so that the length of the cable body 3 that has been rolled up can be grasped at any time through the number observed at the counting port 16;

[0043] Step three, when one end of the cable body 3 needs to pass through the outer threading hole 22, the turntable 23 is rotated by external force to drive the first magnetic circle 231 to rotate. Since the corresponding surfaces of the first magnetic circle 231 and the second magnetic circle 214 attract each other, the transmission disk 211 rotates. The rotation of the transmission disk 211 changes the position of the positioning groove 212, thereby giving a thrust to the linkage frame 242, so that one end of the linkage frame 242 moves along the inner wall of the positioning groove 212, so that the linkage frame 242 moves along the inner wall of the positioning groove 212 from one end close to the inner threading hole 213 to the end close to the transmission disk At one end of the outer edge of 211, the spacing between the multiple linkage frames 242 gradually increases, thereby generating a pulling force on the sealing ring 241, so that the inner diameter of the sealing ring 241 is enlarged, so that the cable body 3 can smoothly pass through the outer threading hole 22 and enter the inner cavity of the connector body 1. When the cable body 3 is docked or wound, by stopping the force on the turntable 23, due to the elasticity of the sealing ring 241 itself, the outer side of the cable body 3 is clamped and tightly fitted to the outer side of the cable body 3, preventing dust and water from entering the inner cavity of the connector body 1 through the connection between the outer threading hole 22 and the cable body 3.
