Abstract

The utility model discloses a special wrench for demounting a hexagon socket head cap screw. The special wrench comprises a handle and a working beam, wherein the working beam is a hexagonal prism; at least one bulge is radially arranged on the surface, of the working beam, in contact with the groove of the hexagon socket head cap screw; the bulge is cuboid; the center line of the bulge penetrates through the center of the hexagonal prism; the bulge extends in the radial direction. The wrench is capable of preventing the hexagon socket head cap screw from slipping, at least one cuboid guide groove is formed in the screw in the radial direction of the hexagon groove; the bulge is matched with the guide groove; when the hexagon socket head cap screw is mounted or demounted, the head of the special wrench is inserted into the hexagon groove, and the bulge of the special wrench is inserted into the guide groove; when the special wrench is rotated, not only are six edge angles of the wrench under applied force, but also one surface of the bulge is directly under stress, the moment of force is transmitted, and the phenomenon of slipping in the demounting process is avoided.

Description

A kind of special spanner of dismantling hexagon socket cap head screw
Technical field
The utility model relates to a kind of special spanner of dismantling hexagon socket cap head screw.
Background technology
Thread connection can be fixed up two or more part relatively, and that thread connection has is simple in structure, mounting or dismounting convenient and connect and reliable etc. have advantage, and in machine-building and engineering structure, application is very wide.Screw attachment is a class of thread connection, and screw, through the through hole of coupled, is then screwed in another screwed hole of coupled, and this connection is without nut, be suitable for one of coupled too thick and do not need the occasion of frequent dismounting.
At present inventor has designed a kind of easy-to-dismount hexagon socket cap head screw, interior hexagonal groove a cuboid guide groove is radially at least set, guide groove is the center through interior hexagonal groove at center line, guide groove radially extends.
Yet, for above-mentioned easy-to-dismount socket head screw, need special-purpose spanner.
Summary of the invention
The utility model aims to provide a kind of special spanner of dismantling hexagon socket cap head screw, in dismounting during hexagon socket cap head screw, stops its head abrasion deformation and skids.
For solving the problems of the technologies described above, the technical solution adopted in the utility model: a kind of special spanner of dismantling hexagon socket cap head screw, comprise handle and working beam, described working beam is six prisms, a projection is radially at least set on the groove contact-making surface of working beam and hexagon socket cap head screw, this projection is cuboid, and protrusion center line is through the center of six prisms, and described projection is radially extended.
On the groove contact-making surface of working beam and hexagon socket cap head screw, be disposed radially three projections.
This spanner is for anti-skidding hexagon socket cap head screw, and this screw radially at least arranges a cuboid guide groove interior hexagonal groove, and this projection and guide groove are suitable, during mounting or dismounting hexagon socket cap head screw, hexagonal groove in the head of special spanner inserts, the projection of special spanner is also inserted guide groove, like this, when rotating special spanner, be not only that spanner stays a corner angle to be subject to active force, and a face of projection is directly stressed, carry-over moment, like this, in unloading process, stop skidding.
Accompanying drawing explanation
Fig. 1 is the utility model overall schematic;
Fig. 2 is working beam end face structure schematic diagram;
In accompanying drawing: 1 working beam 2 handle 3 projections.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
embodiment 1as shown in Figure 1 and Figure 2, a kind of special spanner of dismantling hexagon socket cap head screw, comprise handle 2 and working beam 1, described working beam 1 is six prisms, on the groove contact-making surface of working beam 1 and hexagon socket cap head screw, be disposed radially three projections 3, this projection 3 is cuboid, projection 3 center lines are through the center of six prisms, projection 3 evenly arranges in working beam 1 surrounding, described center line is protruding 3 radial centre lines, and the angle of described center line in horizontal plane is 120 °, and described protruding 3 radially extend.
