[0002] The omni-directional antenna has the characteristics of 360-degree uniform radiation in the horizontal direction, and has a certain width of beam in the vertical direction, so the omni-directional antenna has the characteristics of no directivity and large coverage range. Based on this characteristic, the shape of the omni-directional antenna is mostly irregular, such as hemispherical, cylindrical, conical, disc-shaped and mushroom-shaped. For the surface coating of workpieces with irregular shapes, it has always been difficult. The placement of the workpiece during coating needs to select support points, and the wrong selection of support points will cause:

[0003] 1. The workpiece may shake or even tip over during spraying and transportation.

[0004] 2. The shadow area is too large, and multiple spraying is required, which affects the surface gloss.

[0005] 3. During the spraying process, there are situations such as paint flow and paint accumulation, which cause poor paint film flatness and uneven thickness.

[0006] The above situations not only increase the coating difficulty, but more importantly, directly affect the production cycle and processing efficiency of the product. INVENTION CONTENTS

[0011] Furthermore, the opening and closing structure includes a latch, a hinge, and an opening and closing block; the opening and closing block is located at the top of the support column, and the two are connected on one side by a hinge and on the other side by a latch; the fixed part of the latch is installed on the opening and closing block, and the movable part is installed on the support column; the adjacent sides of the opening and closing block and the support column are provided with grooves, and the two grooves are engaged to form a through hole for the end of the central rotating shaft to pass through.

[0012] Furthermore, one end of the central rotating shaft is provided with an extension arm, and the end of the extension arm is provided with a rotating handle; the rotating handle is parallel to the central rotating shaft, and the extension arm is perpendicular to the central rotating shaft.

[0013] Furthermore, both the opening and closing block and the support column are provided with positioning holes, and the rotating handle has a certain amount of freedom to slide freely in the extension arm; the rotating handle is inserted into the positioning hole for positioning.

[0014] Furthermore, the rotating handle includes a handle section, a sliding section, and a positioning section connected in sequence. Anti-detachment protrusions are fixed at both ends of the sliding section. The sliding section is connected to the extension arm bearing. The positioning section and the support are located on the same side of the extension arm.
