Description
Technical field
The utility model relates to a kind of spanner.
Background technology
Spanner on existing market is of a great variety, there are box spanner, ratchet spanner, slide rail spanner, interior hexagonal polytypic spanner etc., by analyzing, towards two general orientation development, one be polytypic Integrated design, one Tool integration Multiple Type nut, for polytypic Integrated design, often cause complicated structural design, durability becomes problem; Two is the designs of monotype independent, but often needs many spanners different model supporting, and volume and weight is large, causes and carries inconvenience, can not use again if lose a certain model.
Utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition carries out improving to prior art and improves, and provides chain wrench, to realize the object of a wrench operated plurality of specifications screw.For this reason, the utility model takes following technical scheme.
Chain wrench, comprise spanner handle and driving end, described driving end comprises the chain type cephalomere link composition that more piece is provided with different size driving hole, described spanner handle comprises cover of shaking hands, is fixed on the telescopic of cover front end of shaking hands, described chain wrench head intercalation enters in telescopic, and can move forward and backward in telescopic, described telescopic gloves front end of can being in one's hands is elastic.Easy to carry, a spanner can realize the use of multiple different size spanner.
As improving further and supplementing technique scheme, the utility model also comprises following additional technical feature.
A kind of specification spanner hole is provided with in the middle of each cephalomere of described driving end.Conveniently can realize a driving end and can contain plurality of specifications or dissimilar driving hole.
Each cephalomere of described driving end is provided with the section header of convex and the joint tail of spill, often can rotate around the connection axle center of section header and joint tail between joint.Conveniently realize the connection between spanner cephalomere.
The connecting axle of described section header is provided with the resilient and axially consistent blend stop of multi-ribbon, is provided with many shallow slots corresponding with blend stop in the connecting shaft hole of joint tail.Conveniently realize spanner cephalomere revolve cut after temporary fixed.
Described cover appearance of shaking hands is provided with symmetrical tread plate, increases frictional force, prevents from skidding.
Beneficial effect: conveniently realize plurality of specifications, the spanner of multiple kind is integrated on same spanner, when the operation to plurality of specifications and screw, do not need to carry a large amount of spanners.

Fig. 2 is that the utility model uses schematic diagram.
In figure: 1-driving end; 2-spanner handle; 3-telescopic; 4-shakes hands cover; 5-tread plate; 6-saves tail; 7-section header; 8-driving hole.
Detailed description of the invention
Below in conjunction with Figure of description, the technical solution of the utility model is described in further detail.
As shown in Figure 1-2, chain wrench, comprise spanner handle 2 and driving end 1, in order to realize plurality of specifications, the spanner of multiple kind is integrated on same spanner and uses, described driving end 1 comprises more piece chain type cephalomere link composition, a kind of driving hole 8 of specification is provided with in the middle of each cephalomere of driving end 1, the conveniently rotation and temporary fixed that saves of driving end 1, each cephalomere of driving end 1 is provided with the section header 7 of convex and the joint tail 6 of spill, often can rotate around the connection axle center of section header 7 and joint tail 6 between joint, the connecting axle of section header 7 is provided with the blend stop that multi-ribbon is resilient and axis is consistent, many shallow slots corresponding with blend stop are provided with in the connecting shaft hole of joint tail 6.
Conveniently change driving end 1 and easy to use and carry, described spanner handle 2 comprises cover 4 of shaking hands, is fixed on the telescopic 3 of cover 4 front end of shaking hands, described chain wrench head 1 intercalation enters in telescopic 3, and can move forward and backward in telescopic 3, described telescopic 3 gloves 3 front end of can being in one's hands is elastic.
In order to prevent skating, described cover 4 appearance of shaking hands is provided with symmetrical tread plate 5.
During use, retraction telescopic 3, exposes driving end 1, pull-out needs the driving end 1 of corresponding specification to save, if this driving end 1 saves in the inside, change direction after also can pulling out, then driving end 1 is inserted in telescopic 3, driving hole 8 is inserted in screw, transverse rotation is tightened or is unscrewed, if there is the place of depression to need the turn of the screw, can rotates driving end 1 adjacent accordingly and save, make the driving end 1 of needs save downward protrusion, then be inserted in screw and operate.Can flexible Application in multiple occasion.
Chain wrench shown in above Fig. 1-2 is specific embodiment of the utility model; the utility model substantive distinguishing features and progress are embodied; can according to the use needs of reality; under enlightenment of the present utility model; it is carried out to the equivalent modifications of the aspect such as shape, structure, all at the row of the protection domain of this programme.
