[0019] The following specific implementation content provides various different embodiments or examples for implementing the present utility model. Of course, these are only embodiments or examples and are not intended to be restrictive. Additionally, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the present utility model and do not represent a specific relationship between the different embodiments and / or structures being discussed.

[0020] As Figures 1-6 shown, an easy-to-pull plug includes a housing 1 and pins 2 provided on the lower side of the housing 1. On both the left and right sides of the housing 1, auxiliary extraction plates 3 are swingably hinged up and down. A limiting portion is further provided on the housing 1, and the limiting portion is used to limit the swing of the auxiliary extraction plates 3 so that the auxiliary extraction plates 3 are restricted to maintain a horizontal state when swung outwards.

[0021] In the present utility model, two auxiliary extraction plates 3 and a limiting portion are provided on the left and right sides of the housing 1 and are hinged to swing up and down. When it is necessary to extract the plug housing 1, the auxiliary extraction plates 3 on both sides can be swung outwards, and the limiting portion is used to make the auxiliary extraction plates 3 in a horizontal state. Then, the user's fingers can pull the lower side of the auxiliary extraction plates 3, so that the force application is facilitated, and the plug can be easily and labor-savingly extracted.

[0022] See Figure 5 、 Figure 6 As shown in the figure, a hinge shaft 21 is provided on one side surface of the auxiliary extraction plate 3. The side of the auxiliary extraction plate 3 where the hinge shaft 21 is located is a convex portion 22, and the side of the auxiliary extraction plate 3 where the hinge shaft 21 is not located is an operation portion 23. Hinge seats 24 are provided on the left and right sides of the housing 1 at intervals in the front and rear directions, and both ends of the hinge shaft 21 are rotatably installed between the two hinge seats 24.

[0023] Further, the limiting portion includes a limiting seat 31 provided between the two hinge seats 24. When the auxiliary extraction plate 3 swings outwards and the convex portion 22 abuts against the limiting seat 31, the operation portion 23 is in a horizontal state at this time.

[0024] Certainly, the hinge seats 24 are provided at the upper end position of the housing 1. The operation portion 23 is used for the user to pull with fingers, so the area of the operation portion 23 is larger than that of the convex portion 22. When the operation portion 23 rotates outwards around the hinge shaft 21, the convex portion 22 abuts against the limiting seat 31. At this time, the operation portion 23 extends horizontally, so that it is convenient for the user to apply force, and the plug can be easily and labor-savingly extracted.

[0025] See Figure 1 、 Figure 2 As shown in the figure, hooks 51 are provided on the left and right sides of the housing 1. When the auxiliary extraction plate 3 is turned downwards, the hooks 51 can hook the lower end of the auxiliary extraction plate 3, so that the auxiliary extraction plate 3 maintains a vertical shape; thus, the auxiliary extraction plate 3 can be stored, which is convenient for the user to store.

[0026] In order to facilitate the insertion of the auxiliary extraction plate 3 into the hook 51, the inner side corner at the outer end of the auxiliary extraction plate 3 is a bevel structure 61. Certainly, one side of the hook 51 also has a bevel. When the auxiliary extraction plate 3 swings inwards for storage, the bevel structure 61 on the auxiliary extraction plate 3 first contacts the bevel of the hook 51, and the bevel is matched with the bevel, so that the insertion of the auxiliary extraction plate 3 is facilitated.

[0027] Furthermore, the hook 51 and the housing 1 are made of integrally formed plastic material. The plastic has a certain elasticity, so that the hook 51 can clamp the auxiliary extraction plate 3 or enable the auxiliary extraction plate 3 to disengage from the hook 51.

[0028] In the present utility model, there is also a torsion spring 41. The torsion spring 41 is sleeved on the hinge shaft 21 and is used to keep the auxiliary extraction plate 3 in a state of turning outwards. One end of the torsion spring 41 is fixedly arranged on the limit seat 31, and the other end is arranged on the operation part 23.

[0029] When the auxiliary extraction plate 3 disengages from the hook 51, under the action of the torsion spring 41, the auxiliary extraction plate 3 is kept in a state of turning outwards, which is convenient for the user to pull out the plug.
