The working principle and the beneficial effects of the basic scheme are as follows: under the initial condition, the upper cover is closed on the base, the major axis of the oval piece of epaxial ellipse of commentaries on classics this moment is on a parallel with the major axis of semi-elliptical groove, two semi-elliptical groove combinations constitute a complete elliptical groove, oval piece is located the elliptical groove, make two baffles contact each other, thereby two baffles block up the joint of base side completely, can effectually avoid outside dust and moisture etc. to get into the base through the interface this moment inside, avoid contact failure and cause the inside metal of interface to rust, the life of extension interface. When the upper cover is opened, the upper cover drives the movable support and the rotating shaft to rotate, the rotating shaft can drive the oval block to rotate through the torsion spring when rotating, the oval block rotates to push the two baffles to move upwards and downwards respectively, the two baffles are not closed together any more, so that the interface on the side wall of the base is exposed, the baffles do not move any more when the baffles are blocked by the support plate, the upper cover is continuously opened at the moment, the oval block does not rotate any more, and the torsion spring between the rotating shaft and the oval block generates elastic deformation due to the rotation of the rotating shaft. The automatic plugging and opening of the base interface is realized, and the problem that time is wasted due to complex operation of plugging the base interface is solved.

Furthermore, the positioning structure comprises a positioning block fixedly arranged on the rotating shaft, the positioning block is positioned at one end, close to the supporting plate, of the rotating shaft, a plurality of gaskets in close contact are arranged between the positioning block and the supporting plate, and a first spring is arranged between the gaskets. So set up, increase the frictional force between pivot and the backup pad through gasket and first spring, make the movable support can rotate certain angle and can not take place the free motion, realize the activity location of movable support.

Furthermore, the elastic part is a second spring which is wide in source, easy to obtain and low in price.

Further, the movable support comprises an L-shaped movable plate, one end of the movable plate, away from the rotating shaft, is fixedly connected with a supporting rod, one end of the movable plate, away from the supporting rod, is fixedly connected with a connecting plate perpendicular to the movable plate, the rotating shaft is fixedly connected to the connecting plate and perpendicular to the connecting plate, and a plurality of threading holes are formed in the supporting rod. So set up, pass the electric wire in the upper cover from the through wires hole, when making open or closed upper cover, can avoid taking place the confusion between the electric wire.

Further, the gasket includes angle gasket and elastic gasket, and the angle gasket contacts with the backup pad, is equipped with in the backup pad with angle gasket complex stopper. So set up, realize that the angle of pivot is spacing through the angle gasket, improve the stability of movable support through the elastic gasket.
