[0022] In order to make the purpose and advantages of the utility model more clear and apparent, the utility model is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the protection scope specifically requested by the utility model.

[0023] As Figures 1-4 shown, a portable long-size USB connecting line comprises an outer shell 1, a winding shaft 2 rotatably installed in the outer shell 1, a USB connecting line 3, the USB connecting line 3 passing through the winding shaft 2, the USB connecting line 3 being fixedly connected with the winding shaft 2, both ends of the USB connecting line 3 penetrating the outer shell 1 and being movable at the penetration positions. Both ends of the winding shaft 2 penetrate the outer shell 1, a rotating disc 4 is fixedly installed at one outer end of the winding shaft 2, a brake mechanism is arranged on the outer side of the outer shell 1, the brake mechanism being connected with the other outer end of the winding shaft 2, and the brake mechanism being used for braking the end part of the winding shaft 2.

[0024] The brake mechanism comprises a disc 5 fixedly installed at the other outer end of the winding shaft 2, a plurality of spring telescopic rods 6 are installed on the outer side of the outer shell 1 in a circumferential array distribution with the winding shaft 2 as the center, the movable ends of the spring telescopic rods 6 are all installed with friction blocks 7, the friction blocks 7 are tightly attached to the disc 5, and the contact surface between the friction blocks 7 and the disc 5 is provided with anti-skid lines.

[0025] The rotating disc 4 is rotated to drive the winding shaft 2 to rotate, the winding shaft 2 can wind the two end lines of the USB connecting line 3 in the rotating process, so that the USB connecting line 3 is wound on the winding shaft 2 and in the outer shell 1, and the collection of the USB connecting line 3 can be realized and protected in the outer shell 1.

[0026] The brake mechanism is further used for braking the disc 5, so that the disc 5 is not easy to rotate, the winding shaft 2 can be kept in a stable state, and the winding shaft 2 is not easy to reverse and the USB connecting line 3 is not easy to release in the outer shell 1.

[0027] The spring of the spring telescopic rod 6 is in a compressed state, the spring telescopic rod 6 drives the friction blocks 7 to be tightly attached to the disc 5, and the disc 5 is braked by the friction force between the friction blocks 7 and the disc 5.

[0028] The long-size USB line of the application can be reeled in the outer shell 1 and kept in a stable state. Since the USB line can be reeled in the outer shell 1, only the required length needs to be pulled out during use, and it can be easily reeled back when not in use, greatly saving space.
