Abstract

The utility model discloses a make things convenient for screw of hand to twist relates to a screw, including the screw body and revolve wrong part, the screw body is conventional metal screw, revolves wrong part and includes a founding cuboid cavity above the screw cap, and cavity one end is equipped with the confined bottom surface, and other end opening part is equipped with the inside arch of round, is provided with a cuboid extension through the pull structure of drawer type in the cuboid cavity, and the extension lower extreme is equipped with the outside arch of round, extension and cavity have sufficient frictional force, can not take out from the cavity when not having hard outside pull; the extension other end melt-casting has a circular structure, and is equipped with the line on the circular structure and be used for increasing frictional force, and circular structure is adult's thumb size, makes things convenient for the atress, satisfies people and under the condition of this kind of instrument of screwdriver or spanner, just can screw the screw, guarantees fastening and security, convenient to use, and does not influence the normal use of screw.

Description

A kind of screw for facilitating hand stubborn

Technical field

The utility model relates to a kind of screw, specially a kind of screw for facilitating hand stubborn.

Background technique

Screw is commonly used a kind of tool during we live, and can be used to that article is fixed and is assembled, still Generally using must borrow screwdriver when screw or screw tightening can be prevented from falling off that bring is inconvenient or danger by spanner Danger, and will the phenomenon that loosened screw when there is no screwdriver and this tool of spanner under outgoing or specified conditions sometimes It is difficult to handle, if screwing will be easy to make troubles or cause danger not in time.

Summary of the invention

To solve the above-mentioned problems, it the purpose of this utility model is to provide a kind of screw for facilitating hand stubborn, can satisfy People are not in the case where by screwdriver or this tool of spanner, it will be able to by screw means, guarantee tightness and safety Property.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of screw for facilitating hand stubborn, including spiral shell Silk ontology and screw part, the screw ontology is common metal screw, and the part that screws includes a founding in cap nut The cuboid cavity of top, described cavity one end are equipped with closed bottom surface, and other end opening is equipped with the inside protrusion of a circle, long Drawing structure in cube cavity by drawer type is provided with a cuboid extension, and the extension lower end is equipped with one Outside protrusion is enclosed, extension can be prevented to be detached from cavity with the inwardly protruding mutual blocking of cuboid cavities open part, The extension and cavity have enough frictional force, will not extract out out of cavity when not exerting oneself outside pull；It is described to prolong Extending portion divides other end founding to have a circular configuration, and circular configuration is equipped with lines for increasing frictional force, the round knot Structure is adult's thumbnail size, facilitates stress, the part that screws is metal material identical with screw.

The beneficial effects of the utility model are: can satisfy people not by the feelings of screwdriver or this tool of spanner Under condition, it will be able to by screw means, guarantee tightness and safety, it is easy to use, and the normal use of screw is not influenced.

Detailed description of the invention

Fig. 1 is a kind of conventional sense schematic diagram for the screw for facilitating hand stubborn involved in the utility model；

Fig. 2 is a kind of screwed state schematic diagram for the screw for facilitating hand stubborn involved in the utility model；

Fig. 3 is a kind of pull partial structure diagram for the screw for facilitating hand stubborn involved in the utility model；

In Fig. 1-Fig. 3,1 is screw ontology, and 2 be cavity, and 3 be extension, and 4 be circular configuration, 5 be it is inwardly protruding, 6 It is outwardly convex.

Specific embodiment

The principles of the present invention and technical characterstic are described below in conjunction with attached drawing, the embodiment is only that this is practical Novel preferred embodiment, is not intended to limit the scope of the utility model.

A kind of screw for facilitating hand stubborn as shown in Fig. 1-Fig. 3, including screw ontology (1) and screws part, the screw Ontology (1) is common metal screw, and the part that screws includes cuboid cavity (2) of the founding above cap nut, institute Cavity (2) one end is stated equipped with closed bottom surface, other end opening is equipped with the inside protrusion (5) of a circle, and cuboid cavity (2) is interior The drawing structure of drawer type is provided with a cuboid extension (3), extension (3) lower end be equipped with one enclose to Outer protrusion (6) can mutually stop with inwardly protruding (5) of cuboid cavity (2) opening portion, prevent extension (3) It is detached from cavity (2), there are enough frictional force in the extension (3) and cavity (2), will not be from when not exerting oneself outside pull Extraction in cavity (2)；Extension (3) other end founding has a circular configuration (4), and circular configuration (4) is equipped with Lines is adult's thumbnail size for increasing frictional force, the circular configuration (4), facilitates stress, and the part that screws is The identical metal material with screw ontology (1).

According to the above technical scheme, when needing driving screws, using circular configuration (4) by extension (3) firmly from sky It pulls out in chamber (2), then by applying strength on circular configuration (4), can be carried out with screw (1) using lever principle Rotation facilitates and generates enough strength driving screws ontologies (1).

Claims

1. a kind of screw for facilitating hand stubborn, including screw ontology and screw part, it is characterised in that: the screw ontology is conventional Metal screws, the part that screws includes cuboid cavity of the founding above cap nut, and described cavity one end is equipped with envelope The bottom surface closed, other end opening are equipped with the inside protrusion of a circle, are arranged in cuboid cavity by the drawing structure of drawer type There is a cuboid extension, the extension lower end is equipped with the outside protrusion of a circle, can be with cuboid cavities open Partial inwardly protruding mutual blocking prevents extension to be detached from cavity, and the extension and cavity have enough frictional force, It will not be extracted out out of cavity when not exerting oneself outside pull；The extension other end founding has a circular configuration, and It is adult's thumbnail size that circular configuration, which is equipped with lines for increasing frictional force, institute's circular configuration, facilitates stress, described to screw Part is metal material identical with screw.
