[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-3 A portable charger includes a charger body 1, a power cord 2 extending from the bottom of the charger body 1, a storage shell 3 fixedly connected to the bottom of the charger body 1, the power cord 2 passing through the storage shell 3 and slidingly connected to the storage shell 3, a rotating shaft 4 mounted on the left side of the storage shell 3 via a bearing, and a knob 13 fixedly connected to the end of the rotating shaft 4 located outside the storage shell 3. The knob 13 is made of plastic. The provision of the knob 13 facilitates the rotation of the rotating shaft 4.

[0021] Reference Figure 1-4 One end of the rotating shaft 4 located inside the storage shell 3 is fixedly connected to a take-up roller 5, and two winding rods 6 are fixedly connected to the take-up roller 5. The take-up roller 5 and the winding rod 6 are both in contact with the power cord 2. The middle section of the shaft body of the rotating shaft 4 is fixedly connected to a lock disk 7. The left inner wall of the storage shell 3 is fixedly connected to a hollow sleeve 8, and the hollow sleeve 8 is rotatably connected to the outer side of the rotating shaft 4. The interior of the hollow sleeve 8 is slidably connected to a bayonet 9, and the bayonet 9 is engaged with the lock disk 7. The surface of the lock disk 7 is provided with multiple locking grooves, and the end of the bayonet 9 is located in the locking groove. The setting of the locking groove facilitates the engagement of the bayonet 9 at the lock disk 7. A spring 10 is provided inside the hollow sleeve 8, one end of the spring 10 is fixedly connected to the bayonet 9, and the other end of the spring 10 is fixedly connected to the inner surface of the hollow sleeve 8. The setting of the spring 10 can act on the bayonet 9.

[0022] Reference Figure 2 A support sleeve 11 is fixedly connected to the right inner wall of the storage housing 3 and is rotatably connected to the outer side of the take-up roller 5. The provision of the support sleeve 11 provides auxiliary support for the take-up roller 5. A ball bearing 12 is disposed on the inner side of the support sleeve 11 and contacts the take-up roller 5. The provision of the ball bearing 12 reduces friction between the support sleeve 11 and the take-up roller 5.

[0023] The specific implementation process of the utility model is as follows: when in use, after the charger body 1 is used, the rotating shaft 4 is rotated by the knob 13, and the take-up roller 5 and the winding rod 6 on the rotating shaft 4 cooperate to wind the power cord 2 of the charger body 1 around the take-up roller 5, avoiding the power cord 2 from being messy and achieving the purpose of being easy to carry. Moreover, when the rotating shaft 4 rotates, the lock disk 7 on the rotating shaft 4 cooperates with the bayonet 9 supported by the spring 10, which has a locking effect on the rotating shaft 4.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
