That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0022] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a portable notebook computer power adapter connector of the present invention includes a connector body 1 and a plurality of housings 2. The housings 2 are arranged at both ends of the connector body 1. A base plate 3 is installed on the bottom surfaces of the housings 2 and the connector body 1. Both ends of the base plate 3 are bent upward to form lower clamping parts 5. The lower clamping parts 5 are all arranged outside the housings 2. A pressing mechanism is installed on the connector body 1. Central rotating tables 15 are provided inside the housings 2. L-shaped channels 16 are provided at the centers of the central rotating tables 15. Wiring holes 17 are provided on the outer circumferential surfaces of the housings 2 opposite to the openings outside the L-shaped channels 16. Housing covers 14 are installed in the openings at the upper ends of the housings 2. Slip rings 11 are installed at the centers of the housing covers 14. Wires 12 are installed between the fixed ends of the slip rings 11 and the connector body 1.

[0023] In this embodiment, the pressing mechanism includes a top plate 8, a screw rod, a sealed bearing 13 and a hand wheel 9. The top plate 8 is arranged above the connector. The two ends of the top plate 8 extend above the housing 2 and both bend downward to form upper clamping portions 6. Arc-shaped grooves are provided at the positions of the upper clamping portions 6 and the lower clamping portions 5 corresponding to the wiring holes 17. The upper and lower arc-shaped grooves are combined to form a clamping hole 7. A screw hole is provided at the center of the top plate 8. The sealed bearing 13 is embedded and installed on the top surface of the connector body. The screw rod is threadedly connected to the screw hole. One end of the screw rod is installed in the inner ring of the sealed bearing 13, and the other end is fixedly connected to the hand wheel 9.

[0024] In this embodiment, grooves are provided on the bottom surfaces inside the housing 2. Ball bearings are embedded and installed on the bottom surfaces of the grooves. Shaft rods 18 are installed in the inner rings of the ball bearings. The other ends of the shaft rods 18 are installed on the central rotating table 15. Clockwork springs 19 are installed on the outer parts of the shaft rods 18. The outermost circles of the clockwork springs 19 are installed on the inner circumferential surfaces of the grooves.

[0025] In this embodiment, baffles 10 are arranged on both sides of the wire 12. One ends of the baffles 10 are installed on the connector body 1, and the other ends are installed on the housing cover 14. The wire can be limited by the wire, avoiding the placement of the wire being driven when the power cord rotates.

[0026] In this embodiment, the inner side surfaces of the upper clamping portions 6 are in contact with the outer circumferential surfaces of the housing 2, so that the top plate can only move up and down along the outer circumferential surface of the housing, increasing the stability of the movement.

[0027] In this embodiment, a double-sided adhesive 4 is installed on the bottom surface of the bottom plate 3; wherein, the double-sided adhesive is a fixed sticker for car ornaments, so it has firm adhesion and leaves no trace when torn off, avoiding affecting the computer.

[0028] One end of the power cord passes through the L-shaped channel and is connected to the movable end of the slip ring, so that one end of the power cord is centered. The other end of the power cord is wound around the central rotating table and extends to the outside through the wiring hole to be respectively connected to a connector and an interface.

[0029] During use, the device can be adhesively fixed on the back surface of the computer display screen through the double-sided adhesive and is arranged close to the bottom, avoiding affecting the opening of the computer display screen;

[0030] When in use, the power cords on both sides can be directly pulled. The pulling of the power cords drives the central rotating platform, causing the power cords and the central rotating platform to rotate along the shaft rod. The power cords rotate within the slip ring, avoiding torsion. The rotation of the shaft rod drives the spring, putting the spring in a state of storing energy. After the power cords are moved to an appropriate length, the handwheel can be rotated. The rotation of the handwheel drives the screw rod, and the rotation of the screw rod drives the top plate, causing the top plate to move downward. The movement of the top plate drives the upper clamping portion. The power cords can be clamped and positioned by the descending upper clamping portion, restricting the pulled distance of the power cords and avoiding chaos caused by excessive length.

[0031] When not in use, the connector and the interface can be unplugged from the socket and the computer, and the handwheel is rotated in the reverse direction, causing the top plate to move upward and also separating the upper clamping portion from the lower clamping portion. At this time, the power cords can be automatically wound back into the interior of the housing through the reverse torsion of the spring, while the connector and the interface are restricted outside the housing, preventing them from entering the interior of the housing, thus greatly reducing the volume and being integrally arranged with the computer, facilitating carrying.

[0032] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
