The bottom of the lower cover 1 is provided with a mounting slot for fixing a bracket. The bracket has a central tooth in the middle of its top, side teeth on both sides, and arc-shaped positioning ribs on the outer sides of the side teeth. The mounting slot is sized to match the upper portion of the bracket, and positioning grooves that cooperate with the positioning ribs are provided on both sides of the mounting slot. When installing the bracket, the bracket is directly inserted into the mounting slot, and the positioning ribs and the positioning slots cooperate to complete the installation. When removing the bracket, the bracket is directly pulled out of the mounting slot by vertically inserting the lower cover, which is convenient and flexible to use.

[0005] Preferably, a mounting hole for mounting the rotating base is provided in the middle of the fixed base, and two sets of vertical first positioning step teeth and mounting grooves are provided around the mounting hole. Placement grooves are provided on both sides of the first positioning step teeth for placing U-shaped screws. The installation is convenient and the stability is good.

[0006] Preferably, the number of central teeth is 2 to 5, and the central teeth are connected by a connecting piece in the middle. The structure is firm and easy to use.

[0007] As a preference, the middle portion of the bracket is a hollow structure, which is low in cost and easy to process.

[0008] Preferably, the bracket is a trapezoidal structure that is narrow at the top and wide at the bottom, which has good stability and is easy to use.

[0009] The beneficial effects of the utility model are as follows: when installing, the bracket is directly inserted into the installation slot, and the positioning rib and the positioning slot cooperate to complete the installation. When disassembling, the bracket can be directly pulled out of the installation slot by vertically lowering the cover. The operation is convenient and flexible to use.
