Description

Spanner with the capable of regulating pinch

Technical field

The utility model relates to mechanical manufacturing field, relates to specifically a kind of spanner with the capable of regulating pinch that uses when install machinery equipment.

Background technology

Removing and installing in the process of machinery equipment, often want the dismounting screw, in this case, need to use spanner.Because the diameter of the screw that uses is different, therefore need to use the spanner of different bores.For convenience's sake, people often adopt monkey wrench to replace using a string wrench.

Chinese invention patent application numbers 200810139821.8 discloses a kind of monkey wrench, comprise the regular jaw of wrench body front end and the moving jaw that matches, the moving jaw lower shaft is to the with it mobile post of one is set, mobile post is inlaid in the sliding tray and the slide rail adjacent with sliding tray of regular jaw, wherein the inner surface of the sliding tray adjacent with slide rail is the plane, and is corresponding with the shape on the outer surface of the mobile post of this Surface Contact and this plane.

But as known in the art, this spanner can only be used in the situation that screw nut is outstanding plane, when nut is mounted in the depression on the machine surface, just this monkey wrench can't use.And a lot of machinery equipments are for security and the reason such as attractive in appearance, and the situation that nut is under the plane is very common.The workman tends to adopt the torticollis sleeve in this case, and obviously, this needs again with upper complete instrument, still can be absorbed in the condition of inconvenience.

The utility model content

The utility model has namely solved tool set and has carried inconvenient problem by a kind of novel spanner with the capable of regulating pinch is provided, and the monkey wrench that has solved again prior art uses the problem of limitation.

Spanner with the capable of regulating pinch of the present utility model comprises handle, wrench body, front clamping foot and rear pinch, the planar section that the latter half of front clamping foot and rear pinch is semi-cylindrical and described semicolumn forms clamping face, the front clamping foot top is fixed on the wrench body front end, have the adjustment chute at wrench body, rear pinch has the square slider that can be embedded in the adjustment chute and can adjust in the chute mobile by slide block on the first half top, the slide block side is provided with adjusting lever, the adjusting lever end is provided with protrusion, the handle upper surface is provided with one group of protrusion, and the protrusion on the adjusting lever can cooperate with each protrusion of this group protrusion on the handle.During use, the clamping face of front clamping foot is engaged on the face of nut, promotes the adjusting lever moving slider, the clamping face of rear pinch is engaged on the relative face of the face with the front clamping foot clamping of nut, pull handle and get final product the turn of the screw.At this moment, the protrusion of adjusting lever end will cooperate with the protrusion on the handle upper surface, just in time props up adjusting lever and adjusts slide block, and pinch is loosening after preventing when the turn of the screw like this.Each protrusion can adopt various forms, sawtooth for example, outstanding rhabodoid etc., but preferably as shown in fig. 1, protrusion is triangular in shape, a face tilt forward, the bottom surface is vertical with adjusting lever, and each protrusion in that row's protrusion on the handle surfaces is also triangular in shape, and one side forward is vertical with handle surfaces, rear face tilt.After adjusting, during the pinch position, can promote forward adjusting lever with thumb easily like this, and when after behind the pinch in-position, the vertical plane of protrusion props up the vertical plane of adjusting lever protrusion on the handle surfaces, rear pinch can not slide backward.

Slider designs be square be to cause reducing operating efficiency in order to prevent that pinch rotates in the turn of the screw.In order to make pinch more stable, adjusting flange of inner edge design of chute, flange extends along the length direction of adjusting chute, is provided with groove in the relevant position of slide block, and when slide block was embedded in the adjustment chute, described groove just in time cooperated with described flange.In order to make slide block be detachable design with wrench body, flange preferably extends to the position of the distance of a slide block length apart from the rear end from the front end of adjusting the chute side, and slide block can install or remove from adjusting runner rear end like this.This design more can limit the elevating movement of pinch, and what particularly become because be contained on the equipment for a long time at the screw of being twisted itself is tighter, thereby when needing larger torsion just can screw down, this design is more useful.

Front clamping foot can be fixed on by any mode as known in the art the front end of wrench body, such as welding, be spirally connected etc.In a kind of preferred embodiment, front clamping foot is the front end that is fixed on wrench body by rivet.The advantage of rivet is to connect simple and reliable, and intensity is high.

Beneficial effect: the spanner with the capable of regulating pinch of the present utility model is easy to use, can use in multiple occasion, one-object-many-purposes, the sleeve that can substitute one group of different bore uses, and can overcome the defective that existing monkey wrench can not use at the screw that is installed on the concave surface.

Description of drawings

Fig. 1 is the schematic diagram of the spanner with the capable of regulating pinch of the present utility model.

In the drawings: 1 handle; 2 front clamping foots; 3 rear pinches; 4 slide blocks; 5 wrench bodies; 6 adjust chute; The front end of 7 wrench bodies; 8 rivets; 9 adjusting levers; 10 1 groups of protrusions; 11 protrusions; 12 protrusions; 13 flanges.

The specific embodiment

With reference now to the description of drawings spanner with the capable of regulating pinch of the present utility model.

Referring to Fig. 1, comprise handle 1, wrench body 5, front clamping foot 2 and rear pinch 3 with the spanner of capable of regulating pinch.The planar section that the latter half of front clamping foot is semi-cylindrical and described semicolumn forms clamping face, the first half top is fixed on the front end 7 of wrench body by rivet 8, the planar section that the latter half of rear pinch is semi-cylindrical and described semicolumn forms clamping face, have adjustment chute 6 at wrench body, rear pinch has the square slider 4 that can be embedded in the adjustment chute and can adjust in the chute mobile by slide block on the first half top, the slide block side is provided with adjusting lever 9, the adjusting lever end is provided with protrusion 11, is provided with one group of protrusion 10 at the upper surface of handle.As shown in the figure, the protrusion 11 of adjusting lever end can cooperate with each protrusion 12 in this group protrusion 10 of handle upper surface.During use, the clamping face of front clamping foot is engaged on the face of nut, promotes adjusting lever 9 with moving slider, and the clamping face of rear pinch is engaged on the relative face of the face with the front clamping foot clamping of nut, pulls handle and gets final product the turn of the screw.At this moment the terminal protrusion of adjusting lever with cooperating of each protrusion will stop afterwards pinch slip backward in handle surfaces this group protrusion, so cause the operating efficiency reduction because of pinch loosening can avoid the turn of the screw the time.As seen the inside of adjusting in the drawings chute has a flange 13, is designed with the groove that cooperates with this flange 13 at slide block 4, and pinch rocked when the effect that both cooperate can prevent the turn of the screw.

The above is described in detail embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned embodiment, in the ken that affiliated technical field those of ordinary skill possesses, can also under the prerequisite that does not break away from the utility model aim, make a variety of changes.
