Description

The adjustable multipurpose wrench of pinch

Technical field

The utility model relates to mechanical manufacturing field, relates to a kind of adjustable multipurpose wrench of pinch that uses when install machinery equipment specifically.

Background technology

Removing and installing in the process of machinery equipment, often want the dismounting screw, in this case, need use spanner.Because the diameter difference of the screw that uses, therefore needs 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 number 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 mobile post of one with it 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 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 going up 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 providing a kind of novel pinch adjustable multipurpose wrench, and the monkey wrench that has solved prior art again uses the problem of limitation.

The adjustable multipurpose wrench of pinch of the present utility model comprises handle, wrench body, front clamping foot and back pinch, the latter half of front clamping foot and back pinch is semi-annular shape and interior annulus surface forms clamping face, the front clamping foot top is fixed on the wrench body front end, the clamping face of front clamping foot and back pinch is provided with some vertical ridge teeth, have the adjustment chute at wrench body, back 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, handle is provided with adjuster, adjuster is included in the elongated hole of opening on the handle, be located at the tusk on the elongated hole inwall, the adjusting lever end is connected with two elastic arms, these two elastic arms are from the junction terminad toward interior receipts and have outside outstanding endways, described outstanding can the cooperation with the tusk on the elongated hole inwall, other has retainer, and retainer stretches out the strip that a front end has projection forward and is stuck between two elastic arms.During use, the clamping face of front clamping foot is engaged on the nut, promotes the adjusting lever moving slider, make the clamping face engagement nut of back pinch, pull handle and get final product the turn of the screw.At this moment, retainer is pulled back, and the projection of the strip front end that retainer stretches out is forward outwards opened elastic arm, and the terminal outside tusk outstanding and on the elongated hole inwall of elastic arm cooperates, thereby make the back pinch fix, when namely avoiding the turn of the screw after pinch slide backward.The clamping face semicircular in shape has some ridge teeth on the clamping face, therefore when clamping face is meshed nut or nut, the drift angle of nut or nut can be clipped between two ridge teeth, therefore torsion is applied on nut or the nut.Multipurpose screw wrench of the present utility model can be used for twisting the screw of different shape, comprises 4 jiaos, 5 jiaos, 6 jiaos, 7 jiaos etc., only needs a spanner just can be used for various screws, is easy to carry, and is easy to operate.

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 bigger torsion just can screw down, this design is more useful.

Front clamping foot can be fixed on the front end of wrench body by any way as known in the art, for example welds, is 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, the intensity height.

Beneficial effect: the adjustable multipurpose wrench of 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.
