3, the utility model decreases user side and to remove stage makeup and costume remove stage makeup and costume cost and the time cost of tightening nut or fastening silica gel lasso, and does not have waste of material;
4, the utility model eliminates removing stage makeup and costume of tightening nut or fastening silica gel lasso, can realize producing in enormous quantities;
5, reliable performance of the present utility model;
When 6, fixing pcb board, the spatial constraints of the not de-screw periphery of pine of the present utility model is used greatly to improve.
Accompanying drawing explanation
Fig. 1 is the structural representation of the not de-screw of a kind of pine in prior art;
Fig. 2 is the structural representation of the not de-screw of pine in the utility model one embodiment.
In Fig. 1: 1-pine not de-screw, 2-tightening nut;
In Fig. 2: 10-screw body, 110-screw thread, 111-top thread, 20-nut, 30-retainer, 310-step, 40-spring.
Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail embodiment of the present utility model below in conjunction with accompanying drawing.It should be noted that, the utility model accompanying drawing all adopts the form of simplification and all uses non-ratio accurately, only in order to object that is convenient, aid illustration the utility model embodiment lucidly.
As shown in Figure 2, the utility model provides a kind of pine not de-screw, comprise: screw body 10, the nut 20 being arranged on described screw body 10 top, the spring 40 being arranged on the retainer 30 below described screw body 10 and being arranged between nut 20 and retainer 30, bottom described screw body 10, screw thread 110 is set, in described retainer 30, is provided with the step 310 corresponding with described screw thread 110 top thread 111.The utility model by arranging the step 310 corresponding with screw thread 110 top thread 111 described in retainer 30, fixing retainer 30 can be realized without the need to using tightening nut or fastening silica gel lasso, avoid chip mounter/crushing machine to produce in crawl and the de-screw to the process of pcb board of placement pine to rock, avoid the generation of part material casting, reduce cost of production simultaneously.
As preferably, the external diameter of described top thread 111 is greater than the internal diameter of described step 310, and when top thread 111 contacts with step 310, spring 40 is in compressive state.
As preferably, described screw body 10 adopts carbon steel or stainless steel material to make, and described nut 20 adopts metallic aluminium to make, and its surface is provided with stretching line flower.
