Abstract
The utility model provides a buckle formula ratchet spanner, characterized by includes spanner handle (1) and personally experience sth. Part of the body (4) of keeping silent of taking the ratchet, is connected with pawl (2) in spanner handle (1) anterior segment hinge, and pawl (2) form the unidirectional rotation cooperation with ratchet on the body (4) of keeping silent, connect etc. Through the round pin axle (3) and the body (4) the hinge of keeping silent at spanner handle (1) front end, the beneficial effects are that: keeping silent of buckle formula ratchet spanner comprises two sections movable hinges, keep silent and flexiblely to expand, it is folding, can realize being revolved " wound form " the centre gripping of twisting the piece, the demand to installation space has been reduced, the formation that has reduced the installation dead angle maybe, and twisting soon in succession of 180 within ranges can be realized being greater than by the ratchet, the area has been solved to flat part installing and removing fast in narrow space, it has the flexible pile function of launching or tear open to keep silent, can realize " wound form " centre gripping part, solved in extremely narrow space, especially to having only the flat part of a pair of centre gripping, can realize being greater than revolving in succession of 180 within ranges twists.
Description
Art
The utility model relates to mechanical general utility tool technical field.
Background technology
In plant equipment, the part used in many narrow spaces is had to need to tighten, because the rotating range of spanner handle is limited, the jaw of adding open-end wrench is monolithic construction, be tightened part (particularly only having a pair flat part for clamping) in some orientation, it is flat that jaw can not block clamping, forms clamping dead angle.
Summary of the invention
The purpose of this utility model proposes a kind of buckle-type ratchet spanner to solve the deficiency of above-mentioned prior art existence just, and its associated jaw portion is deployable, folding, under extremely narrow space, can tighten from any direction to connector.
The utility model object is achieved by the following technical solution:
A kind of buckle-type ratchet spanner, is characterized in that, comprises the jaw body of spanner handle and band ratchet, and being hinged at spanner handle leading portion is connected to ratchet, and ratchet and the ratchet on jaw body form single direction rotation and coordinate; Be hinged by bearing pin and jaw body in spanner handle front end; Jaw body one end connects jaw arm by hinge axis, is provided with embedding mouth in jaw arm one end, adopts spring and be hinged by hinge to be connected to a buckle at the jaw body other end, and be provided with dop in the end of buckle, dop is connected with embedding mouth inlay card; Jaw arm, buckle, jaw body form jaw jointly, form clamping by jaw to being screwed part.
The beneficial effects of the utility model are, compared with the ratchet spanner of current monoblock type jaw, the jaw of buckle-type ratchet spanner is made up of two sections of hinges, and jaw flexiblely can launch, folds, can realize, to " wound form " clamping being screwed part, decreasing the demand to installing space.Jaw body and handle form ratchet structure, and jaw and handle are rotatable within the specific limits, decrease the formation possibility of installing angle, and ratchet can realize being greater than screwing continuously within the scope of 180 °, solve band to the rapid-assembling/disassembling of flat part in narrow space.
The utility model jaw has flexible expansion or unfolds function, can realize " wound form " holding parts.
The utility model jaw arm end band teeth, when closing, under the effect of spring torsion, teeth can be buckled together, and ensure that jaw can not be thrown off when exerting a force.
The utility model jaw body and handle form ratchet structure, solve in extremely narrow space, particularly to the part only having a pair clamping flat, can realize being greater than screwing continuously within the scope of 180 °.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
See Fig. 1, a kind of buckle-type ratchet spanner, the utility model feature is, comprises the jaw body 4 of spanner handle 1 and band ratchet, and being hinged at spanner handle 1 leading portion is connected to ratchet 2, and ratchet 2 and the ratchet on jaw body 4 form single direction rotation and coordinate; Be hinged by bearing pin 3 and jaw body 4 in spanner handle 1 front end; Jaw body 4 one end connects jaw arm 8 by hinge axis 6, is provided with embedding mouth 8.1 in jaw arm 8 one end, and adopt spring 5 at jaw body 4 other end and be hinged buckle 7 by hinge 6, be provided with dop 7.1 in the end of buckle 7, dop 7.1 is connected with embedding mouth 8.1 inlay card; Jaw arm 8, buckle 7, jaw body 4 form jaw jointly, form clamping by jaw to being screwed part.
The utility model jaw arm 8, buckle 7 can rotate along hinge axis 6, thus realize, to " wound form " clamping being screwed part, decreasing the demand to installing space.
When jaw closes, the twisting force of spring 5, on buckle 7, together with ensureing that the teeth of jaw buckle 7 end sting with the teeth of jaw arm 8 end all the time, forms inner clamping flat.
Handle 1, ratchet 2, bearing pin 3, jaw body 4 form ratchet mechanism, jaw and handle are rotatable within the specific limits, decrease the formation possibility of installing angle, and ratchet can realize being greater than screwing continuously within the scope of 180 °, solve band to the rapid-assembling/disassembling of flat part in narrow space.
The inside clamping shape that buckle-type ratchet spanner jaw is formed is to flat shape, also can be the shape that triangle, rectangle, pentagon, hexagon, octagonal etc. can clamp.
