At present, conventional screw is when fixing, and must grasp screw rod, when proceeding to fixing, there will be screw rod can be askew, and impact is rotated, and in addition, after screw-in, if firmly excessive, screw can be made to damage, and destroy object; After long use, screw loosening, when not noting, screw can drop, and can not use for a long time.
Model utility content
In order to solve in practical operation, during rotating screw, the parts do not buttressed, cause screw twisted, and impact normally uses; And overexert and cause screw to damage when screwing in, after using for a long time, screw can produce loosening, easily drops, and affects the problems such as use.
The utility model proposes a kind of adjustment screw, the screw rod comprising head and be connected with described head, also comprises spring and fixed pedestal; Described screw rod is provided with the first screw thread, and the face that described head and described screw rod are fixed is provided with at least 2 projections, and described projection is positioned at circumferentially same; The fixing port that described fixed pedestal is provided with annular groove and passes for screw rod, in described fixing port, the sidewall of bottom is provided with position limiting convex ring, described spring is fixed on described position limiting convex ring, described screw rod is through described spring and through fixing port through described fixed pedestal, the loose one end of spring is pressed on described head lower surface, when screw rod is downward, described projection can insert in described annular groove, and rotates along described annular groove.
Further preferred version of the present utility model, described screw rod bottom is provided with sharp portion.
Further preferred version of the present utility model, is provided with second screw thread corresponding with the first screw thread of described screw rod inside described position limiting convex ring.
Further preferred version of the present utility model, described fixed pedestal is also provided with at least 4 fixing nails.
Further preferred version of the present utility model, described number of lugs is 4.
Further preferred version of the present utility model, described head upper surface is provided with cross breach.
By technique scheme, the adjustment screw that the utility model proposes, when mounted, can fixedly mount thing surface by fixed pedestal, and after screw rod is inserted spring, hand-held fixed pedestal rotating screw bolt screws in, and spring can keep screw rod vertical, easy to use; In addition, after screwing in installation material completely when screw, Compress Spring, produces a reaction force, prevents ambassador's fixture damage of exerting oneself; This adjustment screw, after long-time use, not easily loosens, can be fixed, can not lose even if loosened screw by spring, may be used for using next time.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan view of the utility model fixed pedestal;
Wherein, 1-head, 2-screw rod, 3-spring, 4-fixed pedestal, 5-first screw thread, 6-projection, 7-annular groove, 8-fixing port, 9-position limiting convex ring, 10-sharp portion, 11-fixing nail, 12-cross breach.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
Composition graphs 1, Fig. 2, the utility model proposes a kind of adjustment screw, and the screw rod 2 comprising head 1 and be connected with described head 1, also comprises spring 3 and fixed pedestal 4; Described screw rod 2 is provided with the first screw thread 5, and the face that described head 1 is fixed with described screw rod 2 is provided with at least 2 projections 6, and described projection 6 is positioned at circumferentially same; The fixing port 8 that described fixed pedestal 4 is provided with annular groove 7 and passes for screw rod 2, in described fixing port 8, the sidewall of bottom is provided with position limiting convex ring 9, described spring 3 is fixed on described position limiting convex ring 9, described screw rod 2 is through described spring 3 and through fixing port 8 through described fixed pedestal 4, the loose one end of spring 3 is pressed on described head 1 lower surface, when screw rod 2 is downward, described projection 6 can insert in described annular groove 7, and rotates along described annular groove 7.
When screw is screwed in fixture by needs, only need be pressed on the surface of fixture by fixed pedestal 4, hand pins fixed pedestal 4, compares traditional single screw easy to use; Rotating screw bolt 2, owing to there being the effect of spring 3, screw rod 2 can not run-off the straight, when screw rod 2 is depressed near fixed pedestal 4, projection 6 can insert in annular groove 7, and projection 6 prevention continues to press down, prevent user firmly excessive, cause head 1 to destroy fixture surface.
Further preferred version of the present utility model, described screw rod 2 bottom is provided with sharp portion 10, and when on the object that screw proceeds to Non-precondition hole, as wood furniture etc., sharp portion 10 makes it more easily proceed to.
Further preferred version of the present utility model, second screw thread corresponding with the first screw thread 5 of described screw rod 2 is provided with inside described position limiting convex ring 9, fixed pedestal 4 can be rotated on screw rod 2 by described second screw thread, is fixed on screw rod 2, after can preventing long-time use on the one hand, screw rod 2 loosens, on the other hand, even if wooden fixture has loosened, coordinate the effect of spring 3, can prevent screw from dropping, lose.
Further preferred version of the present utility model, described fixed pedestal 4 is also provided with at least 4 fixing nails 11, and pedestal is provided with fixing nail 11, adds fixed effect, and first installs fixed pedestal 4 before installing, just without the need to pinning with hand, easy to use.
