Abstract

The invention discloses an easily-screwed screw. The easily-screwed screw comprises a screw head and a screw rod. The screw head is in a flat shape; the screw rod is arranged on the screw head and provided with threads; the outer side wall of the screw head is provided with a protrusion, and the protrusion is provided with a cross recess or a hexagonal counter sink and is in a square shape. According to the easily-screwed screw, the protrusion is arranged on the outer side wall of the screw head and provided with the cross recess or the hexagonal counter sink, which supports special tools, and the protrusion can help a user to tighten the screw conveniently by hand, therefore, the easily-screwed screw can ensure the usage of the original special tools and meanwhile can be easily screwed up without the special tools.

Description

A kind of screw that facilitates degree of tightness
Technical field
The present invention relates to a kind of improvement of screw, refer in particular to a kind of in the situation that do not have the instrument also can be easily by the screw that facilitates degree of tightness of screw-driving.
Background technique
Existing screw, comprise screw head, screw rod usually; Described screw head is flat; On described screw rod, be arranged on screw head, be provided with screw thread on described screw rod; On the outer side wall of described screw head, be provided with cross recess or interior hexagonal counterbore; The screw of this structure in use, must be used special tool, there is no special tool if this just causes temporarily, and must tighten screw the time, can not tighten screw, thereby affect work; For this reason, we have developed a kind of in the situation that do not have the instrument also can be easily by the screw that facilitates degree of tightness of screw-driving.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of in the situation that do not have the instrument also can be easily by the screw that facilitates degree of tightness of screw-driving.
For achieving the above object, the technical solution used in the present invention is: a kind of screw that facilitates degree of tightness comprises screw head, screw rod; Described screw head is flat; On described screw rod, be arranged on screw head, be provided with screw thread on described screw rod; On the outer side wall of described screw head, projection is set; On described projection, be provided with cross recess or interior hexagonal counterbore.
Preferably, described projection is triangular in shape.
Preferably, described projection is quadrilateral.
Preferably, described projection is N limit shape, and N is more than or equal to 5.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The screw that facilitates degree of tightness of the present invention, arrange projection on the outer side wall of described screw head; On described projection, be provided with cross recess or interior hexagonal counterbore; Described cross recess or interior hexagonal counterbore are that special tool is matched, and described projection can conveniently be exerted oneself screw-driving with hand; Like this, under the prerequisite that keeps former professional tool to use, increased and do not had professional tool also can easily tighten screw.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the stereogram that facilitates the screw of degree of tightness of the present invention;
Wherein: 1, screw head; 2, screw rod; 3, projection.
Embodiment
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1 is a kind of screw that facilitates degree of tightness of screw that facilitates degree of tightness of the present invention, comprises screw head 1, screw rod 2; Described screw head 1 is flat; On described screw rod 2, be arranged on screw head 1, be provided with screw thread on described screw rod 2; Projection 3 is set on the outer side wall of described screw head 1; On described protruding 3, be provided with cross recess or interior hexagonal counterbore; Described protruding 3 are quadrilateral.
Certainly, described protruding 3 also can triangular in shape or N limit shape, and N is more than or equal to 5; Described projection can facilitate when dominated by hand firmly, thereby by screw-driving.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The screw that facilitates degree of tightness of the present invention, arrange projection on the outer side wall of described screw head; On described projection, be provided with cross recess or interior hexagonal counterbore; Described cross recess or interior hexagonal counterbore are that special tool is matched, and described projection can conveniently be exerted oneself screw-driving with hand; Like this, under the prerequisite that keeps former professional tool to use, increased and do not had professional tool also can easily tighten screw.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
