Abstract

The utility model relates to a multipurpose staff adjustable spanner which is a hand tool centralizing the functions of a pipe spanner wrench, an adjustable spanner and a staff. The utility model is used for the elastic rotation of mechanical threaded connecting pieces and is composed of a bent spanner body, a jaw-shaped spanner mouth, a worm screw, a pin shaft, a spring and the staff, wherein, the staff is directly arranged on the spanner body by using laser marking technique or galvanic etching technique, and scales on the staff are directly matched with the index mark of the jaw-shaped spanner mouth as a second-use spanner mouth so as to clearly indicate sizes for regulating the opening sizes of the jaw. The utility model has the advantages of reasonable design, novel structure, multi-function on one object and effectively improved work efficiency, being specially suitable for being operated and used in narrow space and positions.

Description

The scale adjustable spanners of using more

The utility model relates to a kind of adjustable spanner, particularly uses the scale adjustable spanner more, and it is a kind of hand-held tool that integrates the function of pipe vice, adjustable wrench, scale, is used for the degree of tightness rotation of mechanical whorl connector.

Use in plain end pipe pincers, the monkey wrench place open in the space, and the nut of turn easily self or worm gear make the openings of sizes of the jaw of clamping object, workpiece be fit to the requirement of work.But the narrow place in the space then can run into and regulate inconvenient trouble, because do not have with reference to the scale of regulating size, it is time-consuming bothersome to make that the user has to, and just can finish the work of using monkey wrench and pipe vice.

The purpose of this utility model is, improve at the deficiency that above-mentioned prior art exists, make have plain end pipe pincers, function that monkey wrench is twisted the clamping threaded connector is integrated in one, and can be suitable for using in narrow space, there is the convenient jaw of regulating to open the scale of size, proposes and design a kind of scale adjustable spanner of using more.

Technical solution of the present utility model is, adopts and pull body, pulls a mouthful band pincers profile of tooth, and worm screw, bearing pin, groups of springs are integrated, and it is characterized in that, pulling the body front portion has scale, and pulling the body afterbody has annular groove to open structure.

It is characterized in that the scale of scale cooperates with a cue mark on pulling mouthful band pincers profile of tooth.

It is characterized in that pulling a mouthful band pincers profile of tooth is that dual-purpose is pulled mouth, the one side has profile of tooth, and its another side is the plane.

It is characterized in that it is that annular recessed edge and the groove that has squarish opened structure that the annular groove of pulling the body afterbody is opened structure.

Advantage of the present utility model is, reasonable in design, the collection pipe vice, adjustable wrench, the function of scale is in one, scale label adopts laser marking technology or galvano-cautery technology to be set directly at and pulls on the body, make scale label evenly clear, durable in use, can be used alternatingly as the dual-purpose mouth of pulling because of pulling a mouthful band pincers profile of tooth, very convenient, regulate freely, overcome existing nothing and regulated the pipe of scale in pincers, monkey wrench is difficulty and not enough when crawl space uses, and can improve the work effect effectively, the utlity model has reasonable in design, novel structure, one-object-many-purposes is closed in the amount kink, aesthetic in appearance, the characteristics that class is high are worth of widely use.

Below, embodiment of the present utility model is described with reference to the accompanying drawings.

As Fig. 1, Fig. 2, shown in Figure 3, the utility model by pull body 1, pull mouthful a band pincers profile of tooth 2, worm screw 3, bearing pin 4, spring 5, scale more than 6 parts form, wherein, pull a mouthful band pincers profile of tooth 2 and be the dual-purpose mouth of pulling, the one side has profile of tooth 8, its another side is the plane, pulling mouthful bottom of band pincers profile of tooth 2 is the tooth bars 10 that cooperate with worm screw 3, pull a mouthful band pincers profile of tooth 2 and very the aspect pull body 1 matched together, it is contained in pulls body 1 head, and be contained in the worm screw 3 of pulling on the body 1 and cooperate, worm screw 3 and spring 5 are contained in by bearing pin 4 and pull on the body 1, worm screw 3 can be rotated pulling on the body 1.One end of bearing pin 4 has screw thread, fix by body 1 upper screwed hole of pulling that bearing pin 4 is installed, pull body 1 front portion and scale 6 directly is provided with the surface of pulling body 1 front portion by laser marking technology or galvano-cautery technology, scale on the scale 6 is with the cue mark 9 on the pincers profile of tooth 2 to cooperate with pulling mouth, to express the open size of jaw.The afterbody of pulling body 1 has annular groove to open structure 7, and this annular groove is opened structure 7 and opened structure for the annular recessed edge and the groove that have squarish.
