Abstract

The utility model relates to a screw, in particular to a universal type screw capable of preventing machinery from being damaged. According to the technical scheme, the screw comprises a screw body and a screw cap, the screw cap is of a hard hexagonal structure, the lower portion of the screw cap is connected with the screw body, threads are machined on the surface of the screw body, the top face of the screw cap is machined into an outer hexagonal face, an inner hexagonal groove opening is formed in the outer hexagonal face, a concave screw driver opening is formed in the inner hexagonal groove opening, and a standby torsion hole is formed in the side wall of the screw cap. The universal type screw has the advantages that a hexagonal screw driver can be used for fixing a screw outer hexagon to screw the screw, an inner hexagonal screw driver, a slot type screw driver and a Philip type screwdriver can also be used for screwing the screw, when the screw cap is damaged by abrasion, a torsion rod can be used for being inserted into the standby torsion hole in the bottom of a nut to loosen the screw, the structure is reasonable, convenience and practicability are achieved, universality is high, replaceability is high, and stability is good.

Description

A kind of universal screw that prevents Focal drug-block

Technical field

The utility model relates to a kind of screw, particularly a kind of universal screw that prevents Focal drug-block.

Background technique

As everyone knows, screw is one of fastening workpiece the most frequently used in people's work for a long time.Known, screw is made up of rivet nut and head of a nail two-part, and the head of a nail adopts plane structure, and end face is provided with draw-in groove.But present screw specification is various, there are a word, cross, interior hexagonal, hexagonal, tack, round end etc., because the screw of different size needs specific screwdriver set, so sometimes need to prepare the screwdriver set of a lot of Zhi Butong in order to unload next piece of screw.Therefore present screw brings a lot of troubles to people sometimes.And in long-term use, the head of a nail is very likely damaged relevant important stressed member because of the cause of mechanical strength and corrosion, cause screw to take out, and then the consequence that causes apparatus to remove.

Summary of the invention

The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of universal screw that prevents Focal drug-block is provided, and can prevent the Focal drug-block causing due to reasons such as long-term use or materials and cannot continue the problem using.

Its technological scheme is: comprise rivet nut and the head of a nail, the described head of a nail is hard hexagonal structure, and the bottom of the head of a nail connects rivet nut, rivet nut surface Machining screw thread; Be processed as outer-hexagonal face at head of a nail end face, outer-hexagonal face is provided with interior hexagonal notch, and interior hexagonal notch place is provided with the sunk screw edge of a knife, and the sidewall of the head of a nail is provided with torsion for subsequent use hole.

The above-mentioned screw edge of a knife adopts indent cross or indent in-line structure.

The beneficial effects of the utility model are: available HEX HEAD CAP SCREWS is criticized retaining screw outer-hexagonal and turned screw, also can criticize with hexagon socket head cap screw, slot type screwdriver, Philip's type screwdriver turn screw, in the torsion for subsequent use hole being worn at the bottom of can passing into nut with torsion rod while destroying, unscrews screw at the head of a nail; It is rational in infrastructure, convenient and practical, versatility is high, and replaceability is strong, and good stability.

Accompanying drawing explanation

Accompanying drawing 1 is structural representation of the present utility model;

Accompanying drawing 2 is structural drawing of the head of a nail of the present utility model;

In upper figure: the screw edge of a knife 1, interior hexagonal notch 2, rivet nut 3, outer-hexagonal face 4, torsion for subsequent use hole 5.

Embodiment

By reference to the accompanying

drawings

1 and 2, the utility model will be further described:

The utility model comprises rivet nut 3 and the head of a nail, and the described head of a nail is hard hexagonal structure, and the bottom of the head of a nail connects rivet nut 3, rivet nut surface Machining screw thread; Be processed as outer-hexagonal face 4 at head of a nail end face, outer-hexagonal face 4 is provided with interior hexagonal notch 2, and interior hexagonal notch 2 places are provided with the sunk screw edge of a knife 1, and the sidewall of the head of a nail is provided with torsion for subsequent use hole 5, and the head of a nail still can be used in the situation that use is damaged.

Wherein, the screw edge of a knife 1 adopts indent cross or indent in-line structure.

When use, available HEX HEAD CAP SCREWS is criticized retaining screw outer-hexagonal and is turned screw, also can criticize with hexagon socket head cap screw, slot type screwdriver, Philip's type screwdriver turn screw, in the torsion for subsequent use hole being worn at the bottom of can passing into nut with torsion rod while destroying, unscrews screw at the head of a nail.
