With the above-mentioned further setting, when the handle is turned downward, the transmission protrusion drives the transmission plate to move, thereby driving the transmission pin in the transmission groove to move, and then driving the sliding cover to reset downward. This linkage mechanism has a simple structure and stable operation. .

Further setting of the utility model: the panel is provided with a rotary damper, the output end of the rotary damper is provided with a gear, the sliding cover is provided with a rack along the vertical direction, and the The gear meshes with the rack.

With the further arrangement above, the provided rotary damper can effectively buffer the sliding of the sliding cover, thereby preventing damage to the sliding cover and prolonging its service life.

The utility model is further set up: the panel is provided with a pressing piece, the pressing piece is provided with a block, the sliding cover is provided with a bayonet corresponding to the position of the block, and the block is buckled. Set in the bayonet.

With the above-mentioned further arrangement, the set pressing piece is fastened in the bayonet socket through the locking block, which can make the sliding cover more stable when it is closed.

The utility model is further set up: a positioning bolt is provided in the panel, a positioning piece is provided on the positioning bolt, a spring is sleeved on the positioning bolt, and the two ends of the spring are respectively connected with the positioning Tablet, tablet conflict.

With the above-mentioned further arrangement, the clamping block can be smoothly disengaged from the bayonet through the spring pressing on the pressing piece, which is more convenient and labor-saving to use.
