Description
Technical field
The utility model relates to threaded fastener dismantling device, particularly relates to the wrench for dismounting of bolt and nut.
Background technology
The instrument of existing dismounting threaded fastener is divided into two classes: a class is slow-witted mouth class spanner, representative is box spanner, be characterized in turning round by complete cycle continuously, dismounting is quick, its shortcoming needs to be furnished with multiple collet head in kit, with the satisfied nut of different size and the needs of bolt, thus cost is high, carries inconvenience.
Another kind of is monkey wrench, for dismounting threaded fastener, after often rotating an angle, spanner must be taken off revolution angle from nut, again be clamped to again on nut, very time-consuming, inefficiency, secondly for hex nut or nut, rev angle can only be 60 °, 120 ° or 180 °, if and during the barriers such as the interior organic frame of these angular ranges, the opening of spanner to clamp nut or nut, thus cannot dismounting.
Utility model content
The purpose of this utility model is the problem that the wrench for dismounting portability and the efficiency that solve threaded fastener can not be taken into account, and provide a kind of unidirectional oneself clamp shfting wrench.
For reaching above-mentioned purpose, the utility model adopts following technical scheme.
A kind of unidirectional from clamping shfting wrench, comprise fixed jaw, fixed jaw is arranged the through hole run through, fixed jaw arranges the chute being communicated with through hole and fixed jaw end face, the in-built accessory of chute connects movable jaw, movable jaw one end arranges the slide plate coordinated with chute, and slide plate connects the cylinder slide block assembled with through hole, it is characterized in that:
The described fixed jaw other end arranges link slot, and described cylinder slide block arranges rack tooth;
In link slot, handle is pulled in assembling, pulls handle one end and arranges gear grooved, pull the longitudinal rod chute that on handle, setting is communicated with gear grooved, pull handle side and arrange the handle runner be communicated with bar chute; Pull handle one end to be assemblied in link slot and to pass through hinge; Pull assembling gear in the gear grooved on handle, and gear is assemblied on bearing pin;
Rigging pilotage bar in bar chute, pin rod one end arranges the gear teeth with gears meshing, and pin rod arranges handle; Handle is assemblied in handle runner; Between handle and fixed jaw, spring is set.
Adopt after technique scheme, this is unidirectional from clamping shfting wrench energy rapid adjustment openings of sizes, and can continuous operation, increases work efficiency; Can adjust between 0 ° ~ 135 ° owing to pulling handle position, can work in small space.

Detailed description of the invention
A kind of unidirectional from clamping shfting wrench, as shown in Figure 1, comprise fixed jaw 1, as shown in Figures 2 and 3, fixed jaw 1 one end arranges fixed arm 1d, fixed jaw 1 is arranged the cylindrical hole 1a run through, and fixed jaw 1 is arranged the chute 1e being communicated with fixed jaw 1 end face and through hole 1a.Link slot 1b is set between fixed jaw 1 other end and through hole 1a, and is communicated with.The sidewall of link slot 1b is arranged the axis hole 1c run through.
The in-built accessory of chute 1e connects movable jaw 2, and as shown in Figure 4, movable jaw 2 main body is that a swing arm 2c, swing arm 2c bottom is connected with slide plate 2d.Slide plate 2d is connected with cylinder slide block 2a, cylinder slide block 2a is arranged the rack tooth 2b of row's straight-side profile, and slide plate 2d fits slidably in chute 1e, and cylinder slide block 2a fits slidably in through hole 1a.
In link slot 1b, assembly connection pulls handle 4, as shown in Figure 5, pull handle 4 one end and gear grooved 4c is set, the sidewall of gear grooved 4c is arranged connecting hole 4d, pull handle 4 side and slot cover 4a is set, the longitudinal rod chute 4b of slot cover 4a subjacent setting party tee section, bar chute 4b is communicated with gear grooved 4c, pull handle 4 side and the square handle runner 4e be communicated with bar chute 4b is set, pulling handle 4 one end is assemblied in link slot 1b, pull assembling gear 3 in the gear grooved 4c on handle 4, bearing pin 8 assembly connection axis hole 1c, connecting hole 4d and gear 3.
Slidable fit pin rod 5 in bar chute 4b, as shown in Figure 6, pin rod 5 one end arranges the single gear teeth 5a engaged with gear 3, the other end arranges strip handle 5b, handle 5b is assemblied in handle runner 4e, and assembly connection cover plate 6 in slot cover 4a, arranges spring 7 between handle 5b and fixed jaw 1.
A kind of unidirectional from clamping shfting wrench, as shown in Figure 1, operation principle is summarized as follows:
Advance the handle 5b on pin rod 5, make gear teeth 5a, engage with gear 3.Pin rod 5 is just connected as a single entity with gear 3 pulling handle 4.Rotate backward and pull handle 4, successively driven gear 3 rotate, rack tooth 2b and moving towards the direction away from fixed jaw 1 with the movable jaw 2 that is integrated, the survivor of a murder attempt opens gradually, rotate forward and pull handle 4, then successively driven gear 3 rotate, rack tooth 2b and moving towards the direction near fixed jaw 1 with the movable jaw 2 that is integrated, the survivor of a murder attempt reduces gradually.Be easy to nut to clamp like this, stop operating and pull handle 4, by means of the pulling force of spring 7, movable jaw 2 and fixed jaw 1 can Automatic-clamping nuts, and this clamping force is called own clamping force.
Firmly rotate forward and pull handle 4, the clamping force of movable jaw 2 and fixed jaw 1 pair of nut increases with external force rapidly and increases, and is exaggerated by lever principle, can hold on to nut and be pulled an angle rotatable.Rotate backward and pull handle 4, the clamping force of movable jaw 2 and fixed jaw 1 pair of nut is provided by spring 7.This power can not make movable jaw 2 and fixed jaw 1 hold on to nut, and movable jaw 2 and fixed jaw 1 will skid on nut, thus makes spanner return an angle rotatable.So alternately handle 4 is pulled in forward and reverse rotation, and this spanner just can complete and tighten or unscrew nut work by continuous print.
Need in some cases to regulate the position of pulling handle 4, method is as follows:
Retract the handle 5b on pin rod 5, gear teeth 5a is departed from gear 3 engage, gear 3 is with to pull handle 4 separate, separately be adjusted to suitable position stop pulling handle 4, again pin rod 5 is advanced, gear teeth 5a is engaged with gear 3, just the angle rotatable pulled when handle 4 works can be adjusted in optimum range, thus avoiding obstacles or can in work in narrow space.Simultaneously due to this spanner to pull handle 4 position adjustable, the operating habit of the person that can adapt to different operating, uses more smoothly.
