The following is a further optimization of the above technical solution according to the present utility model:

the front cover is fixedly connected with an auxiliary rod for enhancing the stability of the front cover in the opening and closing process, and the other end of the auxiliary rod is fixedly connected with a sliding block and is in sliding contact with the inner wall of the box body.

Further, the driving rod is fixedly connected with a limit column and is rotationally connected with the inner wall of the box body.

Further, the driving rod is of a Z-shaped structure.

Further, the transmission mechanism is symmetrically provided with two groups, and the two groups are arranged at the position close to the inner wall of the box body.

Further: two auxiliary rods are symmetrically arranged.

In summary, the rotating rod rotates clockwise, then the rotating rod drives the crank to rotate, the crank and the connecting rod rotate while the crank and the connecting rod rotate, the connecting rod drives the connecting rod to move leftwards, the connecting rod drives the driving rod to move leftwards, the limiting column rotates on the box body under the action of the limiting column on the driving rod, the driving rod jacks up the front cover by utilizing the lever principle, and the front cover is opened in a certain radian at the upper part of the outer side under the action of the driving rod; at the moment, the auxiliary rods are fixedly connected to the front cover, the front cover moves and synchronously lifts the front cover, and the sliding blocks of the auxiliary rods are always in a fitting state with the inner wall of the box body in the moving process; the two groups of transmission mechanisms are symmetrically arranged, the front cover can be guaranteed to be lifted synchronously by the two groups of transmission mechanisms, the front cover is guaranteed to move smoothly in an opening and closing mode, and the front cover is effectively prevented from colliding with the box body.

The rotating rod is rotated anticlockwise, and the front cover can be closed on the box body by utilizing the working process opposite to the working process, so that the sealing and fresh-keeping effects are achieved.
