[0020] See also Figure 1-3A power adapter with anti-pull connection end includes a plug 1, a connecting line 2 and a connector 3. A fixing ring 4 is fixedly connected to one end of the connecting line 2 close to the connector 3, and a fixing strip 11 is fixedly connected to the lower end of the fixing ring 4. The length of the fixing strip 11 is smaller than the length of the connecting line 2. A tooth block 12 is fixedly connected to the lower end of the fixing strip 11. A fixing plate 13 is fixedly connected to the lower end of the plug 1. A notch 14 matching the fixing strip 11 is formed on the fixing plate 13. A stabilizing piece is provided on the side wall of the fixing ring 4, and the stabilizing piece is matched with the connector at the other end of the connector 3.

[0021] Specific working principle and implementation method: the plug 1, the connecting wire 2 and the connecting head 3 are electrically connected, the plug 1 is inserted into the socket, the connecting head 3 is plugged and connected with another connector, and after the connection is completed, the end of the fixing strip 11 on the fixing ring 4 is inserted into the notch 14, and the tooth block 12 is continuously inserted into the notch 14 for limited clamping. After the clamping is completed, the connecting wire 2 can be relaxed, and the fixing strip 11 and the tooth block 12 are applied with force between the plug 1 and the other end connector; the advantage of such a design is that the connecting wire 2 is relaxed, and the fixing strip 11 and the tooth block 12 are fixed in the notch 14. In this way, when the plug 1 and the other end connector are pulled, the fixing strip 11 and the tooth block 12 can play a protective role to prevent the connecting wire 2 from being pulled, and a stabilizing member is provided on the fixing ring 4, which can make the connection between the connecting head 3 and the connector tighter to prevent it from falling off.

[0022] like Figure 1 and Figure 3 As shown, the stabilizing member includes an elastic strip 5, the inner ends of the elastic strip 5 facing each other are fixedly connected to a limiting plate 7, the inner end of the limiting plate 7 is provided with an arc groove 8, one inner end of the elastic strip 5 is fixedly connected to a clamping block 9, the other inner end of the elastic strip 5 is provided with a clamping groove 10 matching the clamping block 9, the facing clamping blocks 9 are matched and connected with the clamping groove 10, after the connector 3 is plugged into the joint, the elastic strip 5 is stretched, the ends of the elastic strip 5 are close to each other, the clamping blocks 9 are inserted into the facing clamping grooves 10, and the arc grooves 8 on the limiting plate 7 are clamped with the outer side of the joint, so that the connection between the connector 3 and the joint can be better and more stable, and the elastic strip 5 and the limiting plate 7 can be tightly clamped with the connector 3 and the joint when pulled, and a force is formed between each other to prevent the joint from falling off.

[0023] like Figure 1 As shown, the middle section of the elastic strip 5 is elliptical, and a through hole 6 is provided in the middle section of the elastic strip 5. The through hole 6 is elliptical. The elliptical shape of the middle section of the elastic strip 5 is to form a larger contact range. The through hole 6 is provided in the middle of the elastic strip 5 to make the pulling force of the elastic strip 5 more elastic, and both sides of the middle section of the elastic strip 5 can be in closer contact with the connector 3 and the joint.

[0024] like Figure 2 As shown, the lower end surface of the fixing plate 13 is flush with the plugging end surface of the lower end of the plug 1, and the fixing plate 13 is fixedly connected close to one end of the connecting line 2. When the plug 1 is inserted into the socket, the fixing plate 13 can play a supporting role, thereby preventing the plug 1 from tilting and falling off when plugged in.
