The working principle of the invention is as follows:

when the plug is used, firstly, the metal sheet 4 on the plug 2 needs to be aligned with the three insertion holes on the socket 9, and part of the metal sheet 4 is put into the insertion holes, at this time, the plug 2 is pressed into the insertion holes, and then acting force is generated on the housing 1, the housing 1 is pushed to move towards the protective cover 3 and compress the first spring 81, so that relative sliding occurs between the plug 2 and the connecting rod 6, at this time, the protrusion 61 moves leftwards along the first track groove 21 until the protrusion 61 contacts with the first inclined surface 71 on the spring seat 7, the protrusion 61 slides along the inclined direction of the first inclined surface 71, due to the inclined action of the first inclined surface 71, the protrusion 61 drives the connecting rod 6 to rotate while sliding, when the protrusion 61 comes to the position shown in fig. 6, the connecting rod 6 rotates to the position shown in fig. 5, so that the clamping groove 62 on the connecting rod 6 rotates to the position aligned with the clamping portion 52, push joint portion 52 card to the joint groove 62 under the effect of second spring 82, it stretches out to drive couple 5 promptly, loosen plug 2 this moment, promote plug 2 and remove left under the effect of first spring 81, make protruding 61 and long inclined plane 22 contact, and remove to the position of figure 9 and fix a position, and then make hook portion 51 and the contact of socket 9 of couple 5 catch with the realization, joint portion 52 then butt under the effect of first spring 81 is at the inner wall of joint groove 62, realize that both ends are injectd, thereby plug 2 can be hung on socket 9, prevent that it from droing, accomplish the installation.

When the plug 2 needs to be detached, the plug 2 is pressed again, the housing 1 is driven to move into the protective cover 3 and compress the first spring 81, so that relative sliding occurs again between the plug 2 and the connecting rod 6, the protrusion 61 is driven to move leftwards and separate from the long inclined surface 22 until the protrusion 61 contacts with the second inclined surface 72 on the spring seat 7, the protrusion 61 slides along the inclined direction of the second inclined surface 72, due to the inclined action of the second inclined surface 72, the protrusion 61 drives the connecting rod 6 to rotate while sliding, the clamping groove 62 and the clamping portion 52 are driven to rotate relatively, so that the clamping portion 52 is gradually lifted upwards and compresses the second spring 82 under the action of the guide inclined surface, when the protrusion 61 reaches the position shown in fig. 12, the connecting rod 6 rotates to the position shown in fig. 11, at this time, the clamping portion 52 overcomes the second spring 82 to completely rotate out of the clamping groove 62, namely, the clamping portion 52 contacts with the outer surface of the connecting rod 6, the hook 51 of the hook 5 retracts into the moving groove to separate the hook 51 from the socket 9, and at this time, the plug 2 is released, and the plug 2 is pushed to move leftwards under the action of the first spring 81, so that the protrusion 61 contacts with the short inclined surface 23 and enters the second rail groove 24 along the short inclined surface 23 to be positioned, and thus the metal sheet 4 can exit from the socket 9, and the disassembly is completed.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
