Abstract
The invention relates to a multipurpose wrench which is composed of a wrench rod and work ends. The multipurpose wrench is characterized in that the two ends of the wrench are respectively provided with two work ends of different shapes, and the two work ends at each end are connected back to back. The working ends of different shapes can be work ends provided with hexagonal holes or dodecagonal holes or can also be fly wheels of which inner shafts are provided with plum blossom structures matched with nuts or can be L-shaped inner hexagonal wrenches. The multipurpose wrench can be fast used without being adjusted and is capable of saving labor in work, convenient to carry, simple in manufacturing technology and low in cost.
Description
Technical field
The present invention relates to a kind of instrument, specifically relate to a kind of combination wrench in dynamo-electric field.
Background technology
Screw is the conventional secure component in dynamo-electric field, in some occasion, the screw of fastening equipment is not wished after fastening released, as: electric power facility, high frame iron tower, cable machinery control cabinet etc., in these occasions, can be unclamped easily by people the screw of connection, can there is potential safety hazard, bring unnecessary trouble to people's live and work.Therefore, for the securing member of these occasions, be generally some screws that must use special spanner just can unclamp of special production, as hexagon socket head cap screw, outer-hexagonal screw etc., must use supporting spanner screw could be unclamped.Conventionally spanner is all opening or the other types clamping part that is shaped with fixed dimension in the one or both ends of shank, in order to twist the screw of corresponding size or structure.Structure is single, during in the face of the difform screw of different size, needs the frequent spanner of changing, and gives to use and carry all to bring inconvenience.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of combination wrench, this spanner can be used for rotating the screw on the securing member of different model.
Unresolved above-mentioned technical problem, the technical solution used in the present invention is: a kind of combination wrench, by wrenching bar and working end, formed, it is characterized in that: spanner two ends are respectively with two difform working ends, and every Duan Liangge working end connects dorsad.
Described difform working end, for hexagon ring ,Shi Erjiao Kong working end, interior axle are with the flywheel of the plum blossom structure matching with nut or the inner hexagon spanner of one-tenth L-type.
Described spanner is conventionally with structural carbon steel or alloy structure steel making.
The present invention can be for the screw of multiple different model and specification, with time according to the feature of the screw on fastened securing member, select corresponding working end, another working end of holding with a firm grip during rotation, firmly rotation, now the effect of spanner handle part also can be served as in this working end, is more conducive to firmly.When the present invention applies, do not need to regulate and can use fast, work laborsaving, easy to carry, and manufacturing process is simple, and with low cost.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
The 1st, wrenching bar, the 2nd, hexagon ring working end, the 3rd, become the inner hexagon spanner working end of L-type, 4 working ends, Shi Shierjiao hole, the 5th, open-end wrench working end.
The specific embodiment
A kind of combination wrench as shown in Figure 1, consists of wrenching bar 1 and working end, and four different operating ends are respectively hexagon ring working end 2, become the inner hexagon spanner working end 3 of L-type, Shi Erjiaokong working end 4, open-end wrench working end 5, difform working end, two, spanner two ends connects dorsad.With time according to the feature of the screw on fastened securing member, select corresponding working end, another working end of holding with a firm grip during rotation, firmly rotation, now the effect of spanner handle part also can be served as in this working end, more be conducive to firmly, during application, do not need to regulate and can use fast, work laborsaving, easy to carry.Spanner adopts structural carbon steel or alloy structure steel making, and technique is simple, with low cost.
Above the present invention is described in detail, but the invention is not restricted to the embodiments described.The equivalence that all Spirit Essences according to the present invention are done changes or modifies, and all should be encompassed in protection scope of the present invention.
Claims (2)
1. a combination wrench, consists of wrenching bar and working end, it is characterized in that: spanner two ends are respectively with two difform working ends, and every Duan Liangge working end connects dorsad.
2. according to a kind of combination wrench described in claim 1, it is characterized in that described difform working end, for hexagon ring ,Shi Erjiao Kong working end, interior axle with the flywheel of the plum blossom structure matching with nut, become any one in the inner hexagon spanner of L-type.
