Abstract

The utility model provides a bent wrench which comprises a holding end and a clamping end. The holding end and the clamping end are connected together to form a body through a bent segment. An angle, which is from 90 degrees to 100 degrees, between the bent segment and the clamping end is formed. The design of the bent segment enables the clamping end to extend into a counter bore or to a bolt or a nut in a narrower scope for the disassembly and assembly or adjustment of the bolt or the nut, thereby avoiding the inconvenience during the disassembly and assembly or adjustment of the bolt or the nut through a conventional wrench.

Description

Bending wrench
Technical field
The utility model relates to the instrument of a kind of installation for load device approach switch, dismounting or adjustment, relates in particular to a kind of bending wrench.
Background technology
In the actual repair or retrofit work of some load devices; as the equipment of the sling and jig kinds such as electronic in crane, hydraulic pressure, machinery; often can touch installation, replacing, dismounting or the adjustment of approach switch in electric fixture, and these operations all must be carried out on special nut.For some countersunk bolts or in the bolt compared with within the scope of narrow space or nut, when the bolt of its inside or nut are loaded and unloaded, common straight spanner loads and unloads bolt or nut owing to cannot crooked stretching into inside, and can be long due to the bolt head having while using box spanner, the sleeve of box spanner also cannot be inserted on the nut on bolt.Yet when not using spanner, traditional method is to use hammer and chisel, by knocking nut, could approach switch be loaded and unloaded or be adjusted.Therefore how to countersunk bolts or in the bolt compared with within the scope of narrow space or nut, to have loaded and unloaded into urgent problem.
Utility model content
The technical problems to be solved in the utility model is in order to overcome in prior art to countersunk bolts or in the defect that the bolt compared with within the scope of narrow space or nut cannot load and unload, a kind of bending wrench to be provided.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of bending wrench, handling for part in load device sling and jig equipment, comprise a holding end and a bare terminal end, and its feature is, described holding end and described bare terminal end connect as one by a bending section, and the angle of described bending section and described bare terminal end is 90-100 degree.
By a bending section, make bare terminal end can stretch into countersunk bolts or compared with the bolt in narrow range or nut place, it tightened or unscrew to realize the charge and discharge operations of bolt or nut.
Preferably, described holding end, described bare terminal end and described bending section are formed in one.
Three sections of one-body molded spanner structures that make are simple, in easy to carry, can also alleviate spanner weight.
Preferably, described holding end is mutually vertical with described bending section, and described holding end and described bare terminal end are parallel to each other.
Described holding end can stretch into compared with within the scope of narrow space described bending section with described bending section is mutually vertical smoothly.
Described bending section is mutually vertical with described bare terminal end.
In a class countersunk bolts, when described bending section is mutual vertical with described bare terminal end, described bare terminal end can be put into smoothly to bolt or the nut place of counterbore, by swinging described holding end, realize the loading and unloading of bolt or nut.
Preferably, described bare terminal end is provided with a bayonet socket, and described bayonet socket is annular saw profile of tooth or polygon.
For difform bolt or nut, the bayonet socket of described bare terminal end is made as to corresponding shape, make bare terminal end can clamp multiple difform bolt or nut.
Preferably, the free end of described holding end is provided with one for loading and unloading a clamp port of nut.
The free end of described holding end is arranged to a clamp port and make described bending wrench also can be used as a straight spanner use simultaneously, thereby expanded the function of this bending wrench.
Preferably, described clamp port is annular saw profile of tooth or polygon.
Positive progressive effect of the present utility model is: the utility model is used this bending wrench to realize handling or adjusting operation easily to countersunk bolts or in the bolt compared with within the scope of narrow space or nut, has solved the problem that common wrench cannot load and unload or adjust this type of bolt or nut.
Accompanying drawing explanation
Fig. 1 is structural representation Fig. 1 of the bending wrench of the utility model embodiment 1.
Fig. 2 is structural representation Fig. 2 of the bending wrench of the utility model embodiment 1.
Fig. 3 is the structural representation of the bending wrench of the utility model embodiment 2.
The specific embodiment
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
Embodiment 1
The present embodiment provides a kind of bending wrench, as shown in Figure 1, comprise a holding end 1 and a bare terminal end 2, holding end 1 connects as one by a bending section 3 with bare terminal end 2, bending section 3 is 90-100 degree with the angle of bare terminal end 2, preferably, bending section 3 be one with the orthogonal staight shank of bare terminal end 2, the structural representation of the bending wrench that described bending section 3 forms is as shown in Figure 2.Holding end 1, bare terminal end 2 and bending section 3 are formed in one.Holding end 1 is mutually vertical with bending section 3, and holding end 1 is parallel to each other with bare terminal end 2.Bare terminal end 2 is provided with a bayonet socket 4, and bayonet socket 4 is polygon, is preferably interior hexagon.The free end of holding end 1 is provided with one for loading and unloading a clamp port 5 of nut, and clamp port 5 is annular saw profile of tooth.
Embodiment 2
The present embodiment provides another kind of spanner, as shown in Figure 1, comprise a holding end 1 and a bare terminal end 2, holding end 1 connects as one by a bending section 3 with bare terminal end 2, bending section 3 is 90-100 degree with the angle of bare terminal end 2, preferably, bending section 3 is one to be the staight shank of 100 degree angles with bare terminal end 2, and the structural representation of the bending wrench that described bending section 3 forms as shown in Figure 3.Holding end 1, bare terminal end 2 and bending section 3 are formed in one.Holding end 1 is parallel to each other with bare terminal end 2.Bare terminal end 2 is provided with a bayonet socket 4, and bayonet socket 4 is polygon.The free end of holding end 1 is provided with one for loading and unloading a clamp port 5 of nut, and clamp port 5 is annular saw profile of tooth.
When bolt is loaded and unloaded, the hex bolts of take in counterbore is example, use described bending wrench that bare terminal end 2 is stretched in countersunk bolts, the bayonet socket 4 of this bending wrench blocks two opposite side of this hex bolts, by holding holding end 1 and it being applied to the power parallel with countersunk bolts tangent to periphery direction, described hex bolts is tightened or unscrewed, thereby realize compared with the handling of narrow range inner bolt or nut or adjustment.
Although more than described the specific embodiment of the present utility model, it will be understood by those of skill in the art that this only illustrates, protection domain of the present utility model is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these changes and modification all fall into protection domain of the present utility model.
