Abstract
The utility model relates to a pressure guide pillar type screw, which comprises a screw head and a screw rod. The pressure guide pillar type screw is characterized in that: a stressed blind hole is formed in a central position at the bottom of a force application groove on the end face of the screw head, is extended along the axial direction of the screw rod, and has the function of a pressure guide pillar. The pressure guide pillar type screw has the advantages that: when the pressure guide pillar type screw is used, the screw can be screwed by arranging a bump at the cutting edge of a screw driver right against the stressed blind hole in the force application groove of the screw head, inserting the bump into the stressed blind hole and rotating the screw driver; and the stressed blind hole has the function of the pressure guide pillar, so that the cutting edge of the screw driver can be locked in the force application groove of the screw head in the process of screwing the screw, the screw and the screw driver can be prevented from being disconnected in a slip way, working efficiency is improved, and the intactness of the force application groove of the screw head can be ensured.
Description
Technical field
The utility model belongs to fastening piece, particularly relates to a kind of pressure guide pillar type screw.
Background technique
Screw is widely used in every field such as production, life as a kind of fastening piece; The screw rod composition that its structure comprises screw head and is connected as a single entity with it; Rounded or the Hexagon of screw head when screw head is rounded, has in-line, cross or interior hexagon application of force groove on its end face.When fastening straight groove or cruciform slot screw; Need screw application of force groove is aimed at and inserted to the cutting edge of screw rotating tool, firmly rotary fastening tool is with screw-driving, owing to the as easy as rolling off a log disengaging screw rotating tool of screw in fastening process; So need to insert repeatedly; So not only prolong the operating time, influence working efficiency, and cause the application of force groove damaged of screw easily.Though interior hexagon screw can solve the slippage problem with screw rotating tool, it is impaired also hexagonal cap to occur through regular meeting in operation, causes the screw of can't screwing fast.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, be convenient to the pressure guide pillar type screw operating and can increase work efficiency.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: pressure guide pillar type screw; Comprise screw head and screw rod, it is characterized in that: said screw head end face application of force bottom portion of groove central position is shaped on the stressed blind hole of extending and can play the effect of pressure guide pillar along the screw rod axial direction.
The utility model can also adopt following technological scheme:
Said screw head end face application of force groove is a straight groove, is shaped on along the screw rod axial direction at the straight groove bottom centre position and extends the stressed blind hole that plays the effect of pressure guide pillar.
Said screw head end face application of force groove is a cross recess, is shaped on along the screw rod axial direction at the cross recess bottom centre position and extends the stressed blind hole that plays the effect of pressure guide pillar.
The cross section of said stressed blind hole is square.
The cross section of said stressed blind hole is rounded.
The cross section of said stressed blind hole is hexagonal shaped.
The cross section of said stressed blind hole is shape from all directions.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, promptly be shaped on the stressed blind hole of extending and can play the effect of pressure guide pillar along the screw rod axial direction in screw head end face application of force bottom portion of groove central position.During use, can the convexity at screw rotating tool cutting edge place be aligned and insert in the stressed blind hole of screw head application of force groove, again rotary screw revolve tool can be very apace with screw-driving.Because stressed blind hole can play the effect of pressure guide pillar, therefore in tightening the process of screw, the cutting edge of screw rotating tool can be locked in the screw application of force groove, so not only can avoid screw and screw rotating tool slippage, increases work efficiency; But also can guarantee the excellent of screw head application of force groove.

Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
When the utility model is tightened; Need to use in-line or the Phillips screw driver that is complementary with the utility model screw head; Promptly be provided with the convexity that is complementary with the stressed blind hole of screw head in the cutting edge neutral position of in-line screw rotating tool; The cutting edge criss-crossing position of Phillips screw driver is provided with the convexity that is complementary with the stressed blind hole of screw head; The convexity at screw rotating tool cutting edge place is aligned and inserts in the stressed blind hole of screw head application of force groove, this moment begin rotary screw revolve tool can be very apace with screw-driving.Because stressed blind hole can play the effect of pressure guide pillar, therefore in tightening the process of screw, the cutting edge of screw rotating tool can be locked in the screw application of force groove, so not only can avoid screw and screw rotating tool slippage, increases work efficiency; But also can guarantee the excellent of screw head application of force groove.
