Patent name: a method for making damping adjusting screws
　　Technical field:
　　The utility model relates to a adjusting screw, in particular to a damping adjusting screw.
　　Background Technology:

　　Due to manufacturing and installation errors, the head of the shadowless lamp and its coupling parts drift and cannot be located in any position. Therefore, in shadowless lamp, damping screw is usually used to provide damping force to realize the position of lamp head and its connecting part. Damping screw requirements can provide appropriate damping force, the damping force can not be too small, to ensure the positioning requirements; At the same time, the damping force can not be too big, to make the user feel comfortable when moving the lamp cap and its connecting part. In addition, in the normal life range, damping screw wear, but also to be able to provide sufficient damping force to meet the lamp cap and its coupling part of the location. The damping screw is tightened by thread, the top pressure disc spring deformation, disc spring top pressure damping head to produce friction, and then provide effective and lasting damping force, damping force can be achieved by adjusting the screw tightness.

　　The technical problem to be solved by the utility model is to provide a damping adjusting screw with simple structure and convenient operation. To solve the technical problems of this practical new type USES the following technical scheme to realize, - kind of damping adjustment screw, its main body is screw, its characteristic is that the screw in front made as terraces, the lower stage of terraces set has a disc spring, disk spring front set has damping, damping head is low front side convex sets limits on the inside. The utility model has the advantages of simple structure, adjustable screw tightness to realize the size of damping force, and convenient use.
