Abstract
The utility model belongs to a screw, which is composed of a screw head and a screw rod. The utility model is characterized in that the screw head is provided with a cross-shaped groove, and a figure-one shape groove throughout the end surface of the screw head is arranged along two cross sides of the cross-shaped groove. The utility model has the advantages of simple structure, convenient processing, high universality, easy use, no influence for torsional strength and strong reliability.
Description
The utility model belongs to a kind of screw.
The screw that uses is made up of screw head and screw rod at present, has cross groove or yi word pattern groove on screw head, can't exchange screw-driver when using owing to above two grooves, so versatility is poor, it is inconvenient to use.
The purpose of this utility model is to address the above problem, and a kind of highly versatile, easy to use, the cross recess screw that do not influence torsional strength are provided.
It is made up of the utility model screw head and screw rod, has cross groove on screw head, has the yi word pattern groove of perforation screw head end face along two cross limits of cross groove.
The utility model is simple in structure, easy to process, highly versatile, easy to use, do not influence torsional strength, good reliability.
Fig. 1 is the utility model structural representation.
Fig. 2 is Fig. 1 plan view.
Fig. 3 is the structural representation of the utility model round head bolt.
Fig. 4 is the plan view of Fig. 3.
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 1, 2, the utility model is made up of screw head 1 and screw rod 2, has cross groove 3 on screw head, has the yi word pattern groove 4 of perforation screw head end face along two cross limits of cross groove.Because yi word pattern groove 4 is to extend along two cross limits of cross groove, does not therefore influence the torsional strength and the versatility of cross groove, has also made things convenient for the use of yi word pattern screw-driver simultaneously, and has increased reliability.
Shown in Fig. 3,4, screw of the present utility model is a round head bolt, has cross groove 5 on screw head, has the yi word pattern groove 6 of perforation screw head end face along two cross limits of cross groove.
