Description
Technical field
The present invention relates to hardware ＆ tools field, is specifically related to a kind of portable wrench.
Background technology
In hardware ＆ tools field, spanner is one of most common instrument, and the various Various Functions of species, in industrial production
In often use bolt, the spanner of the part such as drill bit for screwing outer-hexagonal shape, be often only provided with the end of this spanner
One gib head, is easily slided when screwing drill bit；Meanwhile during screwing, when pinch bar goes to lower section from top, need
Spanner is waited tightening from bolt and removed on part, then, gib head, which is tightened bolt and is rotated down, to be continued to tighten by handle upward；Especially
In some plant equipment, bolt is commonly located at the position of narrow space for it, needs manual adjustable hook head clamping bolt, narrow space
Place's hand is inconvenient to stretch into regulation, not only increases the operating time, and wastes muscle power, increases personnel labor intensity, wastes time and energy, make
With extremely inconvenient.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of portable wrench, it is particluarly suitable for narrow space operation, can
Bolt is tightened in continuous rotation, time saving and energy saving.
A kind of portable wrench of the present invention, including structure identical pulling part I and pulling part II, the He of pulling part I
Pulling part II includes semiclosed elbow and some handles set along the semiclosed elbow lateral wall length direction, two institutes
Semiclosed elbow is stated by snap fastener clamping, forms the positive six prismsby structure with cavity.
Further improve, the cross section of the cavity is regular hexagon.
Spanner of the present invention, its semiclosed elbow make according to the various standard sizes of bolt and produced；It is stubborn when needing
When turning bolt, the spanner of suitable dimension is selected, the semiclosed elbow open butt joint of its pulling part I and pulling part II is stuck in bolt
On, pulling part I and pulling part II are connected together by snap fastener, according to the requirement tightened or loosered a bolt, clockwise or
Handle is rotated counterclockwise, reaches the purpose tightened or loosered a bolt, some handles are uniformly distributed along semiclosed elbow periphery, can be square
Just the angle that the spanner rotates is adjusted, moves spanner at an arbitrary position, easily simplicity is operated, greatly improves operating efficiency, drop
Low labor intensity.
The cavity that two semiclosed elbow clampings are formed, its cross section can be regular hexagon, can also be according to reality
Border demand is processed into other shapes coordinated with bolt.
Further improve, the snap fastener includes regulation shackle member and positioning shackle member, two semiclosed elbows
The regulation shackle member and the positioning shackle member are respectively provided with upper/lower terminal lateral wall, one of them is described semiclosed
The positioning shackle member on elbow and regulation shackle member respectively with the regulation shackle member on another semiclosed elbow and
Positioning shackle member corresponds to clamping.
The both ends of each semiclosed elbow are respectively provided with regulation shackle member and positioning shackle member, two semiclosed elbows two
No matter clockwise or counterclockwise end, can guarantee that two and half respectively by key section shackle member and positioning clamping to clamping
The fastness of elbow clamping is closed, simultaneously as pulling part I is identical with the structure of pulling part II, if one of them is damaged
It is bad, it is easy to maintenance to replace, reduces maintenance cost.
Further improve, the semiclosed elbow is wherein transversely provided with groove, the regulation clamping on the upper surface of one end
Part include the pole that is vertically arranged and be located at its upper end and with its integrally formed bending part, the bending part for transverse direction crotch
Shape structure, its end extend to semiclosed elbow ends this described, the cross section of the groove be it is inverse-T-shaped, the pole
Lower end is fastened in the groove integrally formed with the support base with the fit depressions, the support base, in the groove
Spring is transversely provided with close to one end of semiclosed elbow ends, the other end of the spring is connected with the support base.
Further improve, the positioning shackle member is the inverted "L" shaped structure being engaged with the bending part.
Further improve, the positioning shackle member is integrally formed with the semiclosed elbow.
During II clamping of pulling part I and pulling part, by regulation shackle member to the movement of positioning shackle member direction, shackle member pressure is adjusted
Contracting spring, make bending part and the positioning shackle member clamping of regulation shackle member, regulation shackle member is under the bounce effect of spring, card
Tightening position shackle member.
Further improve, in addition to pin, be arranged with the front-rear side walls of the groove some to through hole, the pin
Both ends are flexibly connected respectively in one pair of which through hole.
The power of engaging part is applied in order to reduce when spanner rotates, while prevents spanner in rotation process, regulation card
Fitting causes because of overstress compression spring and positioning shackle member clamping is not close or threads off, close to pole one above spring
The groove front-rear side walls of side are provided with the through hole that supply and marketing bolt passes through, after the completion of adjusting shackle member and positioning shackle member clamping, by pin
Bolt inserts pole in the through hole of spring side, and through hole of the pin both ends respectively with the groove front-rear side walls is connected, to branch
Bar progress is spacing, prevents it from being moved to spring side；In order to more preferably spacing to regulation shackle member progress, while more share
The power that regulation shackle member is born, pin can be also inserted into for the through hole of one end provided with spring in groove, two pins respectively will
Pole is clipped in the middle, and no matter spanner clockwise or counterclockwise, can share the power that the pole of a part is born.
It is of the present invention to have the beneficial effect that：Simple in construction, easy to use, operation is time saving and energy saving, effectively improves work effect
Rate, reduce labor intensity.
