consult Fig. 1, Fig. 2, Fig. 3, Fig. 4, the present invention includes plug casing 1, stay 2, rotating shaft 3 and draw ring 4 form, described plug casing 1 is that two and half housings fasten the plastic box body that forms, plug casing 1 dual-side is arranged with spring base 13, shaft seat 14 and pull rod slot 16, stay 2 is rectangular sheet, its middle part is provided with axis hole 28 and spring arm 25, one end is provided with lockhole 27, the other end is provided with the bending 29 of " V " shape, draw ring 4 is made of " door " character-shaped pull bar 45 and annulus 46, annulus 46 is located at the top of " door " character-shaped pull bar 45, outwards be arranged with projection 42 on pull bar 45 terminations, inwardly be arranged with retaining step 44, described stay 2 and rotating shaft 3 are two, it is hinged with the shaft seat 14 of plug casing 1 that the axis hole 28 of stay 2 is passed in rotating shaft 3, the spring arm 25 of stay 2 touches with the spring base 13 of plug casing 1, the outside that pull bar 45 parts of draw ring 4 are located in the pull rod slot 16 of plug casing 1 both sides, annulus 46 parts are exposed to plug casing 1, and the projection 42 of pull bar 45 terminations is engaged in the bending 29 of stay 2.

Consult Fig. 1, Fig. 2, described plug casing 1 is provided with pull bar block 12 and pull bar seam 15.

The embodiment of the present invention:

Consult Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6,

the present invention and Socket casing sealed: Socket casing 5 is provided with snap close 51, as long as plug casing 1 is pushed Socket casing 5, can complete the sealed of the present invention and Socket casing, the specific works process further illustrates as follows, an end that plug casing 1 is provided with stay 2 pushes Socket casing 5, the end that stay 2 is provided with lockhole 27 touches snap close 51, snap close 51 puts on stay 2 one reaction forces, force stay 2 to overcome the elastic force of spring arm 25, and make a end that stay 2 is provided with lockhole 27 around the shaft 3 towards the interior gathering of plug casing 1, along with plug casing 1 to Socket casing 5 continue push, lockhole 27 on stay 2 enters into the position of snap close 51, at this moment, the reaction force that snap close 51 puts on stay 2 discharges, under the elastic force effect of spring arm 25, stay 23 opens outside plug casing 1 around the shaft, snap close 51 on Socket casing 5 is sealed with the lockhole 27 of plug casing 1 stay 2, the sealed of the present invention and Socket casing completed.
