The purpose of this utility model can also use following technical measures to solve：

As more specifically scheme, Ka Jiao both sides are corresponded on the edge of the cover plate and are provided with catch, cover plate corresponds to Ka Jiao and set It is jagged.

The cover plate is formed by metal plate punching, and catch is in the same plane with cover plate, and Ka Jiao staggers up and down with catch.Make Cover plate bottom after must installing is smooth, and desk lamp is placed steadily, reliably.

The Ka Jiao is provided with two or more, to play more preferable fixation.

The lid surface is provided with via hole.Via hole can be connected with instrument, in order to accept or reject cover plate by instrument, or Person is by the curved dynamic cover plate of instrument, so that cover plate buckles into the cavity opening of base end face.

The via hole is provided with two, and two via holes are located at cover plate central both sides, in order to auxiliary by instrument and two After helping hole to connect, easily cover plate can be driven to rotate so that cover plate can buckle into the cavity opening of base end face in rotary manner Place.

The cavity opening is rounded, and cover plate is rounded, and three Ka Jiao are evenly equipped with cover plate, circumference where Ka Jiao roots Radius is less than flanging inner radius, and the radius of circumference is more than flanging inner radius where the cantilever outer end of card angle.

The cavity opening is square, and cover plate is square, and cover plate is provided with four Ka Jiao.

The shape of above-mentioned cavity opening is not unique, in addition to circular and be square, can also be other shapes.

The root of the Ka Jiao is trapezoidal, and one end that it is connected with cover plate is wide, and the one end being connected with cantilever is narrow.

The beneficial effects of the utility model are as follows：

（1）Such desk lamp bottom package structure is by setting several Ka Jiao, Ka Jiao overall diameter in the edge of cover plate Smaller than base external diameter, wall base flanging internal diameter is big, and the size of Ka Jiao height of least is equal with flanging thickness, and cover plate can be direct Installed by Ka Jiao and flanging snapping, save material cost significantly and simplify installation procedure；

（2）The cover plate of such desk lamp bottom package structure with the opening of base cavity until coordinate, not by cavity depth shadow Ring, perfect fitting can be realized, improve the yield rate of material, increase the commonality of material, reduce the exploitation of mould.
