Description

A kind of unidirectional from clamping shfting wrench

Technical field

The present invention relates to threaded fastener dismantling device, relate in particular 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 mouthful of class spanner, representative is box spanner, be characterized in complete cycle revolution continuously, dismounting is quick, its shortcoming is in kit, to need to be furnished with multiple collet heads, to meet the nut of different sizes and the needs of bolt, thereby cost is high, carries inconvenience.

Another kind of is monkey wrench, for dismounting threaded fastener, after angle of every rotation, spanner must be taken off to an angle of revolution 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 in these angular ranges when the barrier such as organic frame, the opening of spanner is to clamp nut or nut, thereby cannot dismounting.

Summary of the invention

The object of the invention is to solve the portable problem that can not take into account with efficiency of wrench for dismounting of threaded fastener, and provide a kind of unidirectional from clamping shfting wrench.

For reaching above-mentioned purpose, the present invention adopts following technical scheme.

A kind of unidirectional from clamping shfting wrench, comprise fixed jaw, the through hole running through is set on fixed jaw, fixed jaw arranges the chute that is 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 coordinating with chute, and slide plate connects the cylinder slide block with through hole assembling, it is characterized in that:

The described fixed jaw other end arranges link slot, on described cylinder slide block, rack tooth is set;

In link slot, handle is pulled in assembling, pulls handle one end gear grooved is set, and pulls the longitudinal rod chute that on handle, setting is communicated with gear grooved, pulls the handle runner that handle one side setting is communicated with bar chute; Pull that handle one end is assemblied in link slot and hinged by bearing pin; 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 that engage with gear, and handle is set on pin rod; 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 between 0 ° ~ 135 °, adjust owing to pulling handle position, can in small space, work.

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, and the cylindrical hole 1a running through is set on fixed jaw 1, and the chute 1e that is communicated with fixed jaw 1 end face and through hole 1a is set on fixed jaw 1. Between fixed jaw 1 other end and through hole 1a, link slot 1b is set, and by its connection. The axis hole 1c running through is set on the sidewall of link slot 1b.

The in-built accessory of chute 1e connects movable jaw 2, and as shown in Figure 4, movable jaw 2 main bodys are swing arm 2c, and swing arm 2c bottom is connected with slide plate 2d. Slide plate 2d is connected with cylinder slide block 2a, and the rack tooth 2b of row's straight-side profile is set on cylinder slide block 2a, 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 is pulled handle 4, as shown in Figure 5, pull handle 4 one end gear grooved 4c is set, connecting hole 4d is set on the sidewall of gear grooved 4c, pull handle 4 one sides slot cover 4a is set, the longitudinal rod chute 4b of below, slot cover 4a bottom surface setting party's tee section, bar chute 4b is communicated with gear grooved 4c, pull the square handle runner 4e that handle 4 one side settings are communicated with bar chute 4b, 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 arrange the single gear teeth 5a engaging 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 with the movable jaw 2 being integrated towards moving away from the direction of fixed jaw 1, the survivor of a murder attempt opens gradually, forward rotation is pulled 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 dwindles gradually. Be easy to like this nut to clamp, 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 forward rotation is pulled handle 4, and movable jaw 2 and fixed jaw 1 increase with external force rapidly the clamping force of nut, and are exaggerated by lever principle, can hold on to nut and be pulled an angle rotatable. Rotate backward and pull handle 4, movable jaw 2 and fixed jaw 1 are provided by spring 7 clamping force of nut. 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, thereby makes spanner return an angle rotatable. So replace forward and reverse rotation and pull handle 4, what this spanner just can be continuous complete tightens or unscrews nut work.

Need in some cases to regulate the position of pulling handle 4, method is as follows:

Retract the handle 5b on pin rod 5, make gear teeth 5a depart from and engage with gear 3, gear 3 is with to pull handle 4 separate, separately be adjusted to suitable position and stop pulling handle 4, again advance pin rod 5, gear teeth 5a is engaged with gear 3, just can be adjusted in optimum range by the angle rotatable when pulling handle 4 and work, thus avoiding obstacles or can be in work in narrow space. Simultaneously due to this spanner to pull handle 4 positions adjustable, the person's that can adapt to different operating operating habit, uses more smoothly.
