Abstract

The utility model relates to an abnormal shape spanner, including wrench body, be equipped with the column disc at wrench body's intermediate position, evenly be provided with a plurality of wrenching bar along the circumferencial direction on the surface at the excircle of disc polygon hole I has been seted up at wrench body's upper and lower both ends polygon hole II has been seted up to wrenching bar's work end. The utility model has the advantages of simple structure and reasonable design, two upper and lower work ends through at wrench body all are equipped with regular polygon driving hole, can use simultaneously, simultaneously being equipped with a plurality of little wrenching bar on the outer circumference of disc, both can serving as the spanner, can serve as the handle of wrench body during operation again, different use occasions is satisfied in the make full use of space.

Description

A kind of special-shaped spanner

Technical field

The utility model relates to hardware & tools field, particularly relates to a kind of special-shaped spanner.

Background technology

Spanner is a kind of conventional installation and removal instrument.Most of spanner utilizes lever principle to twist bolt, screw, nut and other screw threads and tightly holds the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is usually shaped with clamp holder portion and applies external force shank and apply external force in the one or both ends of shank, just can twist opening or trepanning that bolt or nut hold bolt or nut.During use, threadingly direction of rotation applies external force at shank, just can twist bolt or nut.In the industry of colliery, be provided with multiple pipe-line system under mine, the pipe assembly in each pipe-line system generally adopts ring flange to connect.When installing, removing pipe-line system, fastening, the dismounting of flange plate bolt are absolutely necessary operation.Because construction environment under mine determines, each pipe-line system is maked somebody a mere figurehead often or is installed near portion of side, tunnel.Existing spanner can only a use, can not use simultaneously, causes the one waste of resource.

Utility model content

The utility model, in order to overcome deficiency of the prior art, provides a kind of special-shaped spanner.

The utility model is achieved through the following technical solutions:

A kind of special-shaped spanner, comprise wrench body, column puck is provided with in the centre position of wrench body, the outer round surface of disk is along the circumferential direction evenly provided with several wrenching bars, offer polygonal hole I at the two ends up and down of described wrench body, offer polygonal hole II in the working end of described wrenching bar.

As optimal technical scheme of the present utility model, the quantity of described wrenching bar is three.

As optimal technical scheme of the present utility model, described wrench body is cylindric.

As optimal technical scheme of the present utility model, the diameter of described wrench body is greater than the diameter of wrenching bar.

As optimal technical scheme of the present utility model, described polygonal hole I is regular hexagon hole.

As optimal technical scheme of the present utility model, described polygonal hole II is regular hexagon hole.

Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, be equipped with regular polygon driving hole, can use simultaneously by two working ends up and down in wrench body; On the excircle of disk, be provided with multiple little wrenching bar simultaneously, both can serve as spanner, handle during wrench body work can be served as again, make full use of space, meet different use occasions.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

Refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, Fig. 1 is axonometric drawing of the present utility model, and Fig. 2 is front view of the present utility model, and Fig. 3 is left view of the present utility model, and Fig. 4 is top view of the present utility model.

Described a kind of special-shaped spanner, comprise wrench body 1, column puck 2 is provided with in the centre position of wrench body 1, the outer round surface of disk 2 is along the circumferential direction evenly provided with several wrenching bars 3, offer polygonal hole I 4 at the two ends up and down of described wrench body 1, offer polygonal hole II 5 in the working end of described wrenching bar 3.

The quantity of described wrenching bar 3 is three, and described wrench body 1 is in cylindric, and the diameter of described wrench body 1 is greater than the diameter of wrenching bar 3, and described polygonal hole I 4 and polygonal hole II 5 are regular hexagon hole.The utility model structure is simple, reasonable in design, is equipped with regular polygon driving hole, can uses simultaneously by two working ends up and down in wrench body; On the excircle of disk, be provided with multiple little spanner simultaneously, make full use of space, meet different use occasions.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
