One end of the connecting rod 302 is fixedly connected to the arc-shaped insert rod 303. The surface of the arc-shaped insert rod 303 is provided with rubber protrusions 304. After being inserted into the slot, the protrusions 304 are in close contact with the inner wall, which not only enhances the friction of the insertion to prevent loosening, but also fills the gap to improve the sealing performance and block dust and moisture. The arc-shaped insert rod 303 is slidably inserted into the inside of the arc-shaped slot, and the surface of the rubber protrusions 304 contacts the inside of the arc-shaped slot.

[0030] The winding assembly 4 includes a worm gear 401 rotatably connected to the inner wall of the cavity. A worm wheel 402 meshes with the surface of the worm gear 401. A round rod 403 is fixedly inserted through the center of the worm wheel 402. One end of the round rod 403 extends into the interior of the housing 1. A turntable 404 is fixedly connected to one end of the round rod 403. Two winding posts 405 are installed on the surface of the turntable 404. As the turntable 404 rotates, the cable is wound and stored. Different types of cables can be classified and sorted to avoid messy tangling and facilitate management and maintenance.

[0031] One end of the worm gear 401 extends to the outside of the housing 1. A handle 5 is fixedly connected to one end of the worm gear 401. Its design increases the point of force application for the hand, making cable winding and unwinding operations easier. It is especially suitable for scenarios in broadcasting engineering where the cable length is frequently adjusted, avoiding the inconvenience caused by directly turning the worm gear 401.

[0032] The surface of the box cover 2 is provided with an observation hole, and a glass 6 is installed inside the observation hole. Without opening the box cover 2, the staff can directly observe the winding status, connection status or any abnormalities of the cables inside the box through the glass 6.

[0033] A push block 7 is fixedly connected to the surface of the lid 2. The push block 7 is rectangular in shape. The design of the push block 7 allows the staff to easily push the lid 2 to slide with their fingers or tools to open or close the box body 1, which solves the problems of slippage and uneven force when directly pushing the edge of the lid 2.

[0037] First step: Turn knob 9, knob 9 drives rotating rod 301 to rotate, rotating rod 301 drives arc-shaped insert rod 303 to rotate in the circular groove through connecting rod 302; when arc-shaped insert rod 303 rotates to align with arc-shaped slot, push the two box covers 2 to bring them closer, and arc-shaped insert rod 303 will be inserted into arc-shaped slot. At this time, rubber protrusion 304 contacts the inner wall of arc-shaped slot, which plays the role of sealing and increasing friction, so that the box cover 2 can be tightly closed on the box body 1;

[0038] The second step: Rotate the handle 5 on the outside of the box 1. The handle 5 drives the worm 401 to rotate. The worm 401 meshes with the worm wheel 402, thereby driving the worm wheel 402 to rotate. The worm wheel 402 drives the turntable 404 to rotate through the round rod 403. The winding post 405 on the turntable 404 rotates together with the turntable 404, winding the cable around the winding post 405, thus realizing the organization and storage of the cable.
