Abstract
The invention relates to a fastener, in particular to a screw and a screwdriver matched with the same. The screw comprises a screw cap and a threaded rod connected with the screw cap. A union groove is formed in the end face of the screw cap and is a cross groove. Two symmetrical notches or four notches are formed from the groove to the rim of the screw cap. The screwdriver matched with the screw to be used comprises a screwdriver handle and a screwdriver rod. A cross protrusion corresponding to the cross groove in the end face of the screw cap is arranged at the top end of the screwdriver rod. The cross protrusion is provided with a pair of symmetrical end points forming sharp ends higher than the protrusion. The notches can be clamped when the screw is rotated. According to the screw and the screwdriver matched with the same, the notches are formed in the union groove of the screw cap, and the screwdriver is provided with the protruding sharp ends in a matched manner, so that through the clamping structure, abrasion of the screw in the screwing process is effectively lowered, and repeated utilization of the screw can be guaranteed.
Description
Technical field
The present invention relates to a kind of fastening piece, particularly a kind of screw and with it with the use of screw-driver.
Background technique
Screw is widely used in various field.In daily life, various electrical equipment, furniture that people use
Even the field such as building, machinery all can use screw, more especially need often to twist, or the screw of recycling, owing to twisting the increase of number of times, add the hardness comparatively large (such as body of wall, hard plank etc.) of securing objects, inevitable for the wearing and tearing of nut engagement groove, screw is finally caused to be scrapped, common common screw, due to material and structural defect, is generally difficult to recycling, result in the waste of resource.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of new engagement groove structure, make screw reuse number of times increase, and Aided design a with the use of screw-driver.
Technical problem to be solved by this invention is achieved by the following technical programs:
A kind of screw, the screw rod comprising nut and be connected with described nut, described nut end face offers engagement groove, and described engagement groove is cruciform groove, and groove to nut edge is provided with two symmetrical breach or four breach.
Further, described groove notch is equal with slot bottom width.
Further, described notch length be less than or equal to that head diameter deducts screw rod maximum diameter 1/2nd.
The screw-driver coordinating above-mentioned screw to use, comprises handle of a knife and knife bar, and described knife bar top is the cross projection corresponding with the cruciform groove of nut end face, and has a symmetrical end points formation higher than the tip of projection, can engage breach during rotary screw.
The present invention has following beneficial effect:
1. the engagement groove notch of nut of the present invention is equal with slot bottom width, and what such design added screw twists intensity, is conducive to recycling.
2. nut engagement groove of the present invention is provided with breach, and screw-driver is combined with protruding tip, and this snap-in structure, effectively reduces the wearing and tearing of screw in twisting, and the repeatedly heavy burden of screw is utilized and is protected.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of screw of the present invention.
Fig. 2 is nut end face structural representation of the present invention.
Fig. 3 is the knife bar apex structure schematic diagram of screw-driver of the present invention.
Embodiment
Below in conjunction with accompanying drawing 1,2,3 and embodiment, the present invention will be described in detail.
As shown in Figure 1, a kind of screw, the screw rod 2 comprising nut 1 and be connected with described nut, described nut end face offers engagement groove 11, described engagement groove is cruciform groove, and described groove notch is equal with slot bottom width, and groove to nut edge is provided with two symmetrical breach 12.Described breach 12 length equal head diameter deduct screw rod immediately nut place diameter 1/2nd.
As shown in Figure 3, the screw-driver coordinating above-mentioned screw to use, comprises handle of a knife and knife bar, and described knife bar top is corresponding with the cruciform groove of nut end face cross protruding 3, and there is a symmetrical end points formation higher than the tip 31 of projection, during rotary screw, breach 12 can be engaged.
The above embodiment only have expressed embodiments of the present invention; it describes comparatively concrete and detailed; but therefore can not be interpreted as the restriction to the scope of the claims of the present invention; in every case the technological scheme adopting the form of equivalent replacement or equivalent transformation to obtain, all should drop within protection scope of the present invention.
