Abstract
A kind of double swing end wrench relates to a kind of hardware ﹠ tools, is made of movable fixed claw 1 and handle claw 2.Handle claw 2 has slotted eye 13 and pin-and-hole 12, and movable fixed claw 1 has pin-and-hole 10, and pin 4 passes pin-and-hole 12, pin-and-hole 10 is fixed on movable fixed claw 1 on the handle claw 2, and an end of spring 5 is fixed on the handle claw 2; The other end is fixed on the movable fixed claw 1.So movable fixed claw 1 can overlap the turret head of designed specification limit admittedly under the effect of spring 5, clockwise direction is pulled and just can be tightened up or loosening hexagon-headed bolt or nut.Simple in structure, operation, easy to use.It had both had the advantage of double end back-up wrench, was pulled workpiece with quilt and was difficult for becoming flexible, skidding; Be applicable to the turret head of pulling plurality of specifications simultaneously.
Description
Technical field the utility model relates to a kind of hardware ﹠ tools, particularly a kind of double swing end wrench.
The double end back-up wrench that background technology is used in the market only is applicable to the turret head of pulling a kind of specification, uses very inconvenient.Known single-end adjustable spanner by the effect of screw rod, tooth bar, can be regulated the size of pulling mouthful, but need unclamp, take out from workpiece during return, changes after the angle workpiece, clamping on the card then again, could continue to pull.Because the wearing and tearing of screw rod tooth bar, the gap increases gradually, become flexible, skid so pull workpiece with quilt easily, and operation, not too convenient when using.
Summary of the invention is in order to overcome the above-mentioned defective of prior art, and the spy provides a kind of double swing end wrench.It has the advantage of double end back-up wrench, is pulled workpiece with quilt and is difficult for becoming flexible, skidding; Be applicable to the turret head of pulling plurality of specifications simultaneously, operate, use also very convenient.
The technical scheme that the utility model adopted is: adopted movable fixed claw 1 and handle claw 2.Handle claw 2 has slotted eye 13 and pin-and-hole 12, and movable fixed claw 1 has pin-and-hole 10, and pin 4 passes pin-and-hole 12, pin-and-hole 10 is fixed on movable fixed claw 1 on the handle claw 2, and an end of spring 5 is fixed on the handle claw 2 by spring steady pin 6; The other end of spring 5 is fixed on the movable fixed claw 1 by spring steady pin 7.So movable fixed claw 1 can overlap the turret head that sets specification limit admittedly under the effect of spring 5, clockwise direction is pulled and just can be tightened up or loosening hexagon-headed bolt or nut.
The beneficial effects of the utility model are: simple in structure, and operation, easy to use.It had both had the advantage of double end back-up wrench, was pulled workpiece with quilt and was difficult for becoming flexible, skidding; Be applicable to the turret head of pulling plurality of specifications simultaneously.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model front view.(when the dotted portion of movable fixed claw 1 represents to pull designed maximum specification turret head with double swing end wrench among the figure, movable fixed claw 1 present position state)
Fig. 2 is the vertical view of the utility model handle claw 2.
Fig. 3 is the front view of the movable fixed claw 1 of the utility model.
Among the figure: 1. movable fixed claw 2. handle claws 3. handle claw heads 4. pins 5. springs 6. spring steady pins 7. spring steady pins 8. movable fixed claw clamping trailing edge 9. handle claw head leading edges 10. pin-and-holes 11. movable fixed claw leading section 12. pin machines 13. slotted eyes.
The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, the utility model is made of movable fixed claw 1 and handle claw 2.Handle claw 2 has slotted eye 13 and pin-and-hole 12, movable fixed claw 1 has pin-and-hole 10, the rear edge part and the pin-and-hole 10 of movable fixed claw 1 are positioned at slotted eye 13, pin 4 passes pin-and-hole 12, pin-and-hole 10 is fixed on movable fixed claw 1 on the handle claw 2, spring 5 is through slotted eye 13, and the one end is fixed on the handle claw 2 by spring steady pin 6; The other end is fixed on the movable fixed claw 1 by spring steady pin 7.Movable fixed claw clamping trailing edge 8, handle claw head leading edge 9 are circular arc, movable fixed claw clamping trailing edge 8 arc diameters, handle claw head leading edge 9 arc diameters respectively with the turret head catercorner length correspondent equal of the designed maximum specification of pulling, the length of movable fixed claw leading section 11 equates with the turret head length of side of the designed minimum gauge of pulling.As designed one is the specification limit of M4 ∽ M8, so movable fixed claw clamping trailing edge 8 arc diameters, handle claw head leading edge 9 arc diameters equate with M8 turret head catercorner length respectively, the length of movable fixed claw leading section 11 equates with the M4 turret head length of side, the movable fixed claw 1 of double swing end wrench is under the effect of spring 5 like this, move in the other direction, can overlap the turret head that sets specification limit admittedly, clockwise direction is pulled and just can be tightened up or loosening hexagon-headed bolt or nut.Simple and convenient, pretty good through test effect.
