[0024] As an optional technical solution of the present invention, the length of the cylinder 15 is equal to the height of the inner wall of the box body 1, and the length of the rectangular opening 11 is equal to the height of the cylinder 15. By using this solution, the storage length of the connecting line 8 can be maximized, and the connection requirements of different lengths can be better adapted. The adaptability is better, ensuring that the present invention is small in size and has better adjustable length.

[0025] As an optional technical solution of the present invention, two protective soft strips 7 are fixedly connected to the outer wall of the box body 1 near the two rectangular openings 11. The length of the protective soft strips 7 is equal to the length of the rectangular openings 11. By using this solution, the friction between the connecting line 8 and the rectangular openings 11 can be reduced during the process of extending, retracting or using the connecting line 8, thereby protecting the connecting line 8 and increasing the practical life of the connecting line 8.

[0026] As an optional technical solution of the present invention, two rotating columns 16 are rotatably connected to the inner wall of the box body 1 near the two rectangular openings 11. The length of the two rotating columns 16 is equal to the length of the cylinder 15. By using this solution, the rotating columns 16 can be used to guide and protect the connecting line 8, so that the connecting line 8 can be better extended and retracted into the interior of the box body 1.

By using this solution, the two splints 13 can be slidably connected to the box body 1 through the sliders 13 and the second strip slide grooves 17, which can limit and stabilize the splints 13.

[0029] This telescopic connecting line requires the following steps when used:

[0030] 1) Move the circular plate 2 to one end away from the box body 1, and the limiting rod 3 moves along with the circular plate 2;

[0031] 2) The rotating circular plate 2 drives the cylinder 15 to rotate. At this time, the two ends of the connecting line 8 located inside the spiral groove 12 can extend or retract from the two rectangular openings 11 according to the direction of rotation.

The rotating shaft 6 is fixedly connected to the cylinder 15, and the cylinder 15 is rotatably connected to the inside of the box body 1. The rotating circular plate 2 drives the cylinder 15 to rotate. At this time, the two ends of the connecting line 8 located inside the spiral groove 12 can extend or retract from the two rectangular openings 11 according to the direction of rotation, so that the length of the connecting line 8 is adjusted. Then the circular plate 2 is moved again to the side close to the box body 1, and the limiting rod 3 is moved to the limiting groove 4 at the same time. Internally, it acts as a limit for the circular plate 2 and the cylinder 15 to prevent the cylinder 15 from rotating at will, which would cause the length of the connecting line 8 to change at will. It is more reliable, simple and quick to operate, and the stability and accuracy of the adjustment are also guaranteed. Finally, the two-way screw rod 9 is rotatably connected to the box body 1 to act as a limit. The two ends of the two-way screw rod 9 are respectively threadedly connected to the two clamps 10. The two clamps 10 are slidably connected to the box body 1 through the second strip slide groove 17 and the slider 13 to act as a limit and stabilizer. Rotating the two-way screw rod 9 can drive the two clamps 10 to move relative to each other, and the box body 1 is clamped and fixed by the two clamps 10, which further reduces the operating difficulty of the utility model and increases the functionality.
