Abstract

The utility model adopts the following technical scheme: a spanner connects rotate handles screw through screw; the rotate handles clutch a groove of a push-and-pull active clamper mutually through a convex groove at the front-end; the clamper is capable of assorting with nuts or pipe fittings and disassembling a fixed mounting; connects the active clamper inside the spanner; outer surface of the spanner is provided with a knurling layer and a locating dowel; a thrust bearing can be put inside the clamper groove to save more effort when using; the convex groove of the rotate handles push-and-pull groove of the clamper; the concave-convex part clutches mutually and makes the handles rotate and then movement is converted into straight line push-and-pull glide through screw thread to hold nut to pipe fittings; also the utility model can be used as hand vice with a ruler, and tightness of spanner opening can be controlled by rotating the handles smoothly, which saves a lot of time and meets operation requirement with such structure.

Description

A kind of multifunctional wrench

Technical field

The utility model relates to the multifunctional wrench of a kind of dismounting, secure cylindrical object or screw and nut and other shaped objects.

Background technology

At present, hold handle when manipulating Adjustable spanner and bulldog wrench on the other hand, the little swiveling wheel that rotates the wrench front end with finger makes the swiveling wheel drive pull a mouthful folding, this transfer swiveling wheel is very time-consuming, more inconvenient, easy slippage when the clamping gripping object, mainly be not clamp function because do not possess vice, degree of tightness is difficult to grasp best elasticated repeatedly, has also wasted a lot of times, the firm power of bulldog wrench by force but very easily damage gripping object, very heavy dumb in the operation, increased workload and used difficulty to the operator, take in the operation to take and carry inconvenience, and give hand feel very stiff, not attractive in appearance yet.

Summary of the invention

In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of use, carries a kind of more easily multifunctional wrench.Not only needn't rotate the little swiveling wheel of front end during use with finger, just can grasp the degree of tightness of the folding of pulling mouthful in use smoothly during the rotary spanner handle, also can be used as the use of hand vice and ruler, and the precision height, thereby it is enlarged the scope of application, and convenient to use attractive in appearance.

In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: this spanner comprises pulls body, handle, folder tooth, pull body inside the through hole whorl that is mated is arranged, pull body by the rotary handle screw thread that is threaded, rotary handle is by the groove of the mutual interlock push-and-pull of front end tongue live splint tooth, and folder tooth folder tooth can cooperate with nut or pipe, it detachably fixedly mounts, connect the live splint tooth in pulling body, the folder tooth is in pulling mouth, and pulling external surface has annular knurl layer and alignment pin.

During use, with spanner mouth clamping nut or pipe fitting etc., pulling mouth can cooperate with nut or pipe with folder tooth folder tooth, the folder tooth detachably fixedly mounts, the folder flank of tooth has cross waves, cross waves can the fastening multiple shape of clamping, and be not easy to crush and hold thing, thereby the clamping face that cross waves enlarges, the folder tooth folder flank of tooth also can zigzag or other shape, pull external body annular knurl layer and screw thread alignment pin are arranged, folder tooth side has and pulls the keyway that the body alignment pin is connected round slip, and the alignment pin screw thread goes into to press from both sides round location in the tooth side keyway by pulling body drop, and folder tooth keyway can prevent to press from both sides the tooth left-right rotation by alignment pin, also can twist alignment pin and make folder tooth and handle location, folder tooth afterbody has and can push away the groove that draws with the mutual interlock of the tongue on the turning handle.The handle front portion has and the mutual interlock of folder tooth groove pushes away the protuberance that draws, also can put into thrust bearing in the folder tooth groove, use more laborsaving, the groove of the tongue push-and-pull folder tooth of rotary handle, concavo-convex mutual interlock makes the handle rotation be converted into the straight line push-and-pull by screw thread and slides, and comes clamping nut or pipe fitting etc., can also use as hand vice and ruler, during use smoothly rotary handle just can grasp the elasticity of the folding of pulling mouthful, saved a lot of times, use such constructor closing operation instructions for use.

Owing to pull a mouthful direction lateral edges scale arranged along pulling body, the mark of indicating graduation is arranged on the corresponding folder tooth, the handle tail end has annular knurl layer and circular hole, thus handle with pull the body afterbody be circle use take take very dexterous quick, and precision height, and very attractive in appearance.

Description of drawings;

Below in conjunction with accompanying drawing the utility model is described further;

Fig. 1 is the front view of the utility model embodiment one,

Fig. 2 is the perspective view of the utility model embodiment one,

Among the figure; 1 pulls body, 2 handles, and 3 folder tooth folder teeth, 4 keyways, 5 scales, 6 tongues, 7 alignment pins, 8 grooves, 9 circular holes, 10 through hole whorls, 11 annular knurl layers 12 are pulled mouth, 13 annular knurl layers.

The specific embodiment:

As Fig. 2 perspective view, pulling mouth 11 can cooperate with nut or pipe with folder tooth folder tooth 3, folder tooth folder tooth 3 detachably fixedly mounts, folder tooth folder tooth 3 faces have cross waves, cross waves generally is used in the vice jaw, can the fastening multiple shape of clamping, and be not easy to crush gripping object, therefore cross waves has enlarged clamping face, folder tooth folder tooth 3 faces also can be with zigzag or other shape, pull body 1 outside annular knurl layer and screw thread alignment pin 7 are arranged, folder tooth 3 sides have and pull the keyway 4 that body 1 alignment pin 7 is connected round slip, and alignment pin screw thread 7 goes into to press from both sides round location in the tooth 3 side keyways 4 by pulling body drop, presss from both sides tooth keyway 4 and can prevent to press from both sides tooth 3 left-right rotation by alignment pin 7, also can twist alignment pin 3 and make folder tooth and handle 2 location, folder tooth 3 afterbodys have and can push away the groove 8 that draws with the tongue 6 mutual interlocks on the turning handle 1.Handle 2 front portions have and the 8 mutual interlocks of folder tooth 3 grooves push away the tongue 6 that draws, also can put into thrust bearing in the folder tooth groove 8, use more laborsaving, the groove 8 of the tongue 6 push-and-pulls folder tooth 3 of turning handle 1 handle 1, concavo-convex mutual interlock makes handle 2 be converted into the straight line push-and-pull by through hole whorl 10 and slides, come clamping nut or pipe fitting, can also use as hand vice, during use smoothly turning handle 2 just can grasp the elasticity of pulling mouthfuls 12 folding, a lot of times have been saved, use such constructor closing operation instructions for use, pull mouthful 12 direction lateral edges scale 5 is arranged owing to pull body 1, the mark of indicating graduation is arranged on the corresponding folder tooth, pulling body 1 has annular knurl layer 12 with handle 2 tail ends, 13 with circular hole 9, handle 2 is circle with plate body 1 afterbody.This uses novel use to take by very dexterous quick, and very attractive in appearance.

Certainly; this turning handle 2 is converted into the straight line push-and-pull by screw thread 10 and slides; come clamping screw and nut or pipe fitting; can also adopt other manners; as passing through the mutual interlock of tongue and groove; (or putting into thrust bearing in the groove 8) makes by screw thread rotation and is converted into the straight line push-and-pull, and such manner all drops within the protection domain of the present utility model.

The utility model is not limited only to above-mentioned embodiment.
