Embodiment
Combine accompanying drawing and preferred embodiment that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
See also shown in Figure 1ly, the utility model provides a kind of turning shaft structure that is used for light fixture, and it comprises:
One copper nut assembly 1, described copper nut assembly 1 is provided with bearing 11, and described bearing 11 is hollow and at inner edge internal thread is set, and the cross section of said bearing 11 is a round end flat key shape, and described copper nut assembly 1 is in order to be set on the lamp working of plastics;
One friction pads 2, described friction pads 2 is provided with axis hole 21, and described axis hole 21 shapes are corresponding with the bearing 11 of copper nut assembly 1, and described friction pads 2 is set on the bearing 11, and described friction pads 2 adopts nylon or graphite nylon material;
One dwang 3, described dwang 3 is provided with a through hole 31;
One metal position limit cycle 4, described metal position limit cycle 4 is provided with a trepanning 41, and described trepanning is a round end flat key shape, and is corresponding with metal screw axial region 61, and is set on the metal screw axial region 61;
