Abstract
The utility model discloses an internal hexagonal wrench, wherein the cross section of the internal hexagonal wrench is in a regular hexagon shape; the overall shape of the internal hexagonal wrench is L shape; the internal hexagonal wrench is formed by bending a regularhexagonal prism with one edge thereof as the benchmark; a long handle and a short handle are formed after the regular hexagonal prism is bent; the long handle is perpendicular to the short handle, and the length ratio of the long handle to the short handle is 3: 1 to 8: 1. The end of the long handle of the internal hexagonal wrench can be a flat head or a hexagonal spherical head universal to the existing internal hexagonal wrenches. The internal hexagonal wrench is simple in structure and convenient to operate.
Description
Technical field
The utility model relates to extracting tool technical field, relates to particularly a kind of inner hexagon spanner.
Background technology
Inner hexagon spanner is a kind of conventional hardware & tools, can be used for tightening and dismantling of hexagon socket head cap screw.See figures.1.and.2, current existing inner hexagon spanner is to form take a face of positive six prisms as benchmark bending, and inner hexagon spanner is divided into long handle and short handle, in use, normally by the regular hexagon groove in the bolt head of hexagonal in long handle or short handle insertion, after turning an angle, then rotate in another position with long handle or short handle insertion groove, until tighten or demounting bolt.But, the locational space of installing when bolt has in limited time, after inner hexagon spanner inserting bolt, spanner just can only rotate a low-angle (being less than 60 degree), and just cannot be inserted into another position in bolt indentation after the inner hexagon spanner after rotation low-angle is extracted, also just cannot be rotated further bolt again, therefore, have a strong impact on the installation and removal of bolt.
Therefore, designing a kind of inner hexagon spanner simple in structure, that can be applicable to various occasions is a technical problem of needing solution badly.
Utility model content
The purpose of this utility model is a kind of simple in structure, easy to operate, long service life of design, is used in conjunction with existing inner hexagon spanner, realizes the inner hexagon spanner without dead angle wrenching bolt.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of inner hexagon spanner, the cross section of described inner hexagon spanner is regular hexagon, the global shape of described inner hexagon spanner is L-shaped, it is characterized in that: described inner hexagon spanner is to form take wherein seamed edge of positive six prisms as benchmark bending, after described positive hexagonal prismoid bending, form long handle and short handle, described long handle is mutually vertical with short handle, and the Length Ratio between described long handle and short handle is 3:1-8:1.Wherein: positive hexagonal prismoid bending part is circular arc, can strengthen like this intensity of whole spanner.In addition, its long handle and short handle cross section are regular hexagon, but the cross section of the junction of long handle and short handle (being the bending part of inner hexagon spanner) is regular hexagon or ellipse, can reduce like this processing and manufacturing difficulty.
In the utility model: tack or six rib bulbs are selected in the long handle termination of inner hexagon spanner.
The cross section of the bending part of inner hexagon spanner is hexagon or ellipse, can reduce like this processing and manufacturing difficulty.
The beneficial effects of the utility model:
Inner hexagon spanner of the present utility model is take a seamed edge of positive six prisms as benchmark, being bent into 90 degree forms, different from the bending benchmark of the inner hexagon spanner on market, differ 30 degree, the inner hexagon spanner on market forms take a face of positive six prisms as benchmark bending.So in use can form complementation.Can realize little space turn hexagon socket head cap screw, increase exponentially the occasion of use, increase work efficiency.
Inner hexagon spanner of the present utility model not only can be realized the function of single spanner, and with existing spanner be alternately used in conjunction with can be in little space turn hexagon socket head cap screw, expand its scope of application.The short handle length of inner hexagon spanner of the present utility model is determined according to long-term use experience, the Length Ratio of long handle and short handle is 3:1-8:1 simultaneously, turn bolt that can either be convenient and strength-saving, and long handle again can be because of not long and not portable simultaneously, increase work efficiency, improve its Portability simultaneously.
Accompanying drawing explanation
Fig. 1 is existing inner hexagon spanner structural representation.
Fig. 2 is that the A-A of Fig. 1 is to view.
Fig. 3 is structural representation of the present utility model.
Fig. 4 is that the B-B of Fig. 3 is to view.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1: as shown in Figure 3 and Figure 4, for the embodiment of inner hexagon spanner of the present utility model, described inner hexagon spanner 1 is to form with a wherein seamed edge bending of positive six prisms, after described positive six prism bendings, form long handle 11 and short handle 12, described long handle 11 is mutually vertical with short handle 12, and the Length Ratio between described long handle 11 and short handle 12 is 4:1.Inner hexagon spanner 1 of the present utility model not only can be realized the function of single spanner, and with existing spanner be alternately used in conjunction with can be in little space turn hexagon socket head cap screw, expand its scope of application.Inner hexagon spanner 1 long handle 11 of the present utility model is 4:1 with the Length Ratio of short handle 12, turn bolt that can either be convenient and strength-saving, and long handle 11 can, because of long and not portable, not increased work efficiency again simultaneously, improves its Portability simultaneously.
In the present embodiment, described inner hexagon spanner 1 is the inner hexagon spanner of steel matter.Short handle 12 length of described inner hexagon spanner 1 are 18mm, and the length of described long handle 11 is 72mm.The length setting of short handle 12 and long handle 11, can guarantee enough moments of torsion of inner hexagon spanner 1, handled easily and being easy to carry about with one.
Operation principle: inner hexagon spanner 1 of the present utility model is used in conjunction with existing inner hexagon spanner.Existing inner hexagon spanner is inserted in hexagon socket head cap screw and rotates 30 °, pull out again and change another position that inner hexagon spanner 1 of the present utility model inserts hexagon socket head cap screw groove into and turn again 30 °, extract again and change existing inner hexagon spanner into and turn again, recycle like this, can realize little space degree of tightness hexagon socket head cap screw, reduce much troubles.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be limited to these embodiment shown in this article, but will accord with principle disclosed herein and features of novelty the widest consistent scope.
