So that the circumferential surface of the product 2 is uniformly wiped, the circumferential surface gloss of the product 2 is consistent, and the surface quality of the product 2 is improved.

In an embodiment, the swing member 122 has a first side wall 123, a second side wall 124, a third side wall 125 and a fourth side wall 126, which are sequentially connected to form a housing cavity 127, wherein the first side wall 123 and the third side wall 125 are disposed opposite to each other along a direction perpendicular to a rotation plane of the rotation table 111, and the second side wall 124 and the fourth side wall 126 are disposed opposite to each other along a direction parallel to the rotation plane of the rotation table 111.
