The utility model discloses have multiple removable wrench end, can just fix firmly reliably convenience safe in utilization according to use needs quick replacement, the handle of this spanner can extend as required, realizes the most laborsaving user state in limited working space.
Description
Technical field
The utility model relates to a kind of Combined wrench, and particularly relating to a kind of head-exchangeable can Lengthened wrench.
Background technology
Spanner is a kind of conventional installation and removal instrument, it utilizes lever principle to twist bolt, screw or nut, spanner generally include shank and in shank one or both ends for the open slot of grip bolt or nut or trepanning, during use, threadingly direction of rotation applies external force at shank, just can twist bolt or nut.
Spanner comprises many types, as fork spanner, double offset ring spanner, combination wrenches, adjustable wrench, hook spanner, box spanner, inner hexagon spanner, torque spanner etc., applies very extensive.But when embody rule, due to often different spanners will be selected according to field condition, cause facility complexity, carry the problems such as inconvenience, add the labour intensity of workmen, reduce efficiency of construction.In addition, pinch bar is more long more laborsaving, but considers the restriction of working space or site specific, and pinch bar length conventional is at present all very short, and therefore also result in workmen's labour intensity increases, the problem that efficiency of construction is low.
Summary of the invention
The utility model provides a kind of head-exchangeable can Lengthened wrench, have multiple replaceable driving end, quick-replaceable can be needed according to use, and be connected by trapezoidal notch and clamp button of the spring structure 2 kinds of forms between driving end with driving end connecting rod, fixation is reliable, safe and convenient to use; The handle of this spanner can lengthen as required, realizes most labour-saving using state in limited operation space.
In order to achieve the above object, the utility model realizes by the following technical solutions:
A kind of head-exchangeable can Lengthened wrench, comprise driving end, driving end connecting rod and multiple extension bar, described driving end and driving end connecting rod are by trapezoidal notch and clamp button of the spring anatomical connectivity, trapezoidal notch is made up of with the trapezoidal fixture block being located at driving end connecting rod top the trapezoidal draw-in groove being located at driving end bottom, and the opening of trapezoidal draw-in groove outwards shrinks by driving end is inner; Clamp button of the spring structure is made up of with the spring top bead being located at the trapezoidal fixture block correspondence position of driving end connecting rod the movable push bar being located at driving end trapezoidal draw-in groove both sides; Be threaded connection between extension bar and driving end connecting rod and between extension bar and extension bar.
Described driving end be double offset ring spanner at hand, opened wrench head, outer hexagonal spanner head or socket head.
Compared with prior art, the beneficial effects of the utility model are:
Have multiple replaceable driving end, can need quick-replaceable according to use, and be connected by trapezoidal notch and clamp button of the spring structure 2 kinds of forms between driving end with driving end connector, fixation is reliable, safe and convenient to use; The handle of this spanner can lengthen as required, realizes most labour-saving using state in limited operation space.

In figure: 1. driving end 11. trapezoidal draw-in groove 2. movable push bar 3. driving end connecting rod 31. trapezoidal fixture block 32. changeover portion 33. connecting rod 34. internal thread connecting hole 4. spring top bead 5. extension bar 51. external screw thread connector
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
See Fig. 5, structural representation of the present utility model (for 3 extension bars), a kind of head-exchangeable of the utility model can Lengthened wrench, comprise driving end 1 (as shown in Figure 1), driving end connecting rod 3 (as shown in Fig. 2-Fig. 3) and multiple extension bar 5 (as shown in Figure 4), described driving end 1 and driving end connecting rod 3 are by trapezoidal notch and clamp button of the spring anatomical connectivity, trapezoidal notch is made up of with the trapezoidal fixture block 31 being located at driving end connecting rod 3 top the trapezoidal draw-in groove 11 being located at driving end 1 bottom, the opening of trapezoidal draw-in groove 11 outwards shrinks by driving end 1 is inner, clamp button of the spring structure is made up of with the spring top bead 4 being located at driving end connecting rod trapezoidal fixture block 31 correspondence position the movable push bar 2 being located at driving end trapezoidal draw-in groove 11 both sides, be threaded connection between extension bar 5 and driving end connecting rod 3 and between extension bar 5 and extension bar 5.
Described driving end 1 be double offset ring spanner at hand, opened wrench head, outer hexagonal spanner head or socket head.
Driving end 1 and driving end connecting rod 3 adopt trapezoidal notch to be connected, because its outward opening shrinks, therefore the effect be locked is had at Impact direction, prevent the trapezoidal fixture block 31 of driving end connecting rod in use procedure from skidding off from the trapezoidal draw-in groove 11 of driving end, increase security, make it be connected firmly.The clamp button of the spring structure simultaneously adopted, can realize quick-replaceable driving end 1, facilitates it to use, and improves the efficiency of tool changing.
The top of driving end connecting rod 3 is the trapezoidal fixture blocks 31 coordinated with trapezoidal draw-in groove 11, and bottom is the connecting rod 33 used as pinch bar, and connecting rod 33 is cylinder, by changeover portion 32 transition between itself and trapezoidal fixture block 31.Internal thread connecting hole 34 is established bottom connecting rod 33, for connecting extension bar 5, the head of extension bar 5 establishes external screw thread connector 51, afterbody is also provided with internal thread connecting hole, external screw thread connector 51 can be connected with the internal thread connecting hole 34 of driving end connecting rod 3 or other extension bar 5, and the segmentation realizing pinch bar lengthens.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
