Abstract

A screw suitable for a plurality of fastening tools comprises a threaded body (10) and a screw cap (20) arranged at tail end (11) of the threaded body (10), wherein a fastening slot (30) is arranged on the upper surface of the screw cap (20); a recessed hexagonal or hexagonal star fastening hole (40) is arranged on the center of the upper surface of the screw cap (20); the outer edge of the screw cap (20) is square or hexagonal; the fastening slot (30) is l-shaped slot or cross-shaped slot. By adopting the technical scheme, a plurality of fastening tools can be used for fastening the screw, so the problem that the fastening tools can not be used as a result of space limitation is solved.

Description

The screw that adapts to multiple fastened tools

Technical field

The utility model relates to secure component, particularly the fastening screw that uses in the narrow zone.

Background technique

Fastening screw of the prior art, only be provided with on general its tail end nut and be adapted to single fastened tools, and often for narrow narrow and small position, some inner spaces, the instrument that is fit to not necessarily can be put to good use open, often because the setting tool scarcity, and screw can't be installed smoothly and with the situation of screw tightening.

Summary of the invention

The utility model provides a kind of screw that adapts to multiple fastened tools, on the basis of the single fastened tools of original adaptation, increase to adapt to the fastening position of multiple fastened tools, solves in the prior art because spatial constraints, technical problem that can't fastening screw.

The scheme that the utility model solves the problems of the technologies described above is: the screw of the multiple fastened tools of this adaptation, and the nut that comprises threaded body and be arranged at the threaded body tail end, this nut upper surface is provided with binding groove; Described nut upper surface center portion is provided with the fastener hole that caves in.

The outer rim of described nut is polygonal, and at least two limits in these a plurality of limits of nut outer rim are parallel edges, and the outer rim of described nut is square or is regular hexagon; The section of described fastener hole is regular hexagon or positive Hexangular Star; Described binding groove is " one " font groove or " ten " font groove; The screw terminal of described threaded body is flat-head shape or tip shape.

The utility model adopts above-mentioned technological scheme, can solve spatial constraints, the problem that fastened tools can't be put to good use with multiple fastened tools fastening screw.

Fig. 1 is the schematic perspective view that adapts to the screw of multiple fastened tools.

Fig. 2 is the schematic perspective view of square nut.

Fig. 3 is the schematic perspective view of hex nut.

Embodiment

In conjunction with above-mentioned description of drawings embodiment of the present utility model.

By among Fig. 1 as can be known, the screw of the multiple fastened tools of this adaptation, the nut 20 that comprises threaded body 10 and be arranged at threaded body 10 tail ends 11, these nut 20 upper surfaces are provided with binding groove 30; Described nut 20 upper surface center portions are provided with the fastener hole 40 that caves in.It is fastening that binding groove in the utility model on the nut is suitable for screwdriver set, when the screw longitudinal space is restricted, when screwdriver set can't use, can adapt to the spanner of interpolation type, the interpolation of spanner is partly inserted in the fastener hole 40 that caves in, and pulling spanner just can fastening screw.

By among Fig. 2 and Fig. 3 as can be known, the outer rim of described nut 20 is polygonal, at least two limits in these a plurality of limits of nut 20 outer rims are parallel edges, and the outer rim that specifically can design described nut 20 is the square (see figure 2), and the outer rim that also can design described nut 20 is the regular hexagon (see figure 3).The outer rim of nut 20 is designed to polygonal, socket spanner easy to use, spanner wrench or socket wrench, and fastening screw can carry out in the side of screw, can solve the narrow problem of screw axial space.

By among Fig. 2 and Fig. 3 as can be known, consider and to make fastened tools when fastening screw, can use power, simultaneously, also to guarantee to avoid occurring the situation that fastened tools can't insert when screw is fastening, described fastener hole 40 sections can be designed as and are the regular hexagon (see figure 2), also can be designed as to be positive Hexangular Star (see figure 3).Be regular hexagon and can use inner hexagon spanner, be designed to positive Hexangular Star, can use the star spanner.

By among Fig. 2 and Fig. 3 as can be known, described binding groove 30 is " one " font groove (see figure 2) or " ten " font groove (see figure 3); The screw terminal 12 of described threaded body 10 is flat-head shape (see figure 2) or tip shape (see figure 3).

Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
