Description

Multifunctional wrench

A kind of multifunctional wrench is used for the solid operation of fastening reconciliation of screw, nut, pipeline, instrument and accessory thereof, belongs to the hardware ﹠ tools technical field.

Before the utility model was made, in prior art, the spanner kind was more, as adjustable wrench, fork spanner, double offset ring spanner, pipe vice, Chain wrench etc.Roughly form by spanner and spanner handle.Driving end is installed on the spanner handle or driving end and spanner handle are connected as a single entity.Though its structure is uncomplicated, function ratio is more single during use, especially to the securing member of various different sizes need fastening, must select the supporting use of above-mentioned spanner for use when regulating.Make troubles to the user in practical operation, operational motion is many, the use cost height, and inefficiency, and also improper use also can damage surface of the work and directly influences its product quality.

Thereby the purpose of this utility model is to overcome above-mentioned weak point and provides a kind of simple in structure, and cost of manufacture is low, and the securing member of applicable all size, is placed on the workpiece and need take off fastening adjustment, finishes until work, and can connect the multifunctional wrench of work.

Main solution of the present utility model is achieved in that

The utility model mainly is made up of spanner elbow 1, handle 2, spring leaf 4.It is characterized in that spanner elbow 1 head is shaped on that to draw angle profile of tooth, tooth angle angle be 30 °-65 °, handle 2 heads are shaped on and push away the anterior angle profile of tooth, and the tooth angle angle is for being 30 °-65 °.

Description of drawings:

Fig. 1 is the utility model structural representation:

Fig. 2 is the utility model spanner elbow structure figure:

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

The utility model spring leaf 4 adopts screw 5 to be fixed in handle 2 grooves, and spanner elbow 1 adopts screw 3 to be fixed on the handle 2, and limited block 6 is fixed on the spanner elbow 1, and its effect is to keep opening distance, rises spacing and the protection spring action.Be shaped on the spanner elbow head 1 and draw the angle profile of tooth, draw the angle tooth to be divided into preceding end tooth, middle end tooth, back end tooth, first tooth to the angle of between cog not is 116 °-120 °, and the end tooth position is a circular arc in the system.The angle at its three end teeth angle is 30 °-65 °, and handle 2 heads are shaped on and push away the anterior angle profile of tooth, and the angle of its tooth angle also is 30 °-65 °.The spanner handle head is a circular arc, and its radius is R16-100mm.Spanner handle head R can select the multifunctional wrench of a series of making different sizes such as 18mm, 25mm, 35mm, 65mm, 90mm, 100mm as required, and certain handle 2 is the corresponding lengthening along with the variation of Wrench head also, widens.

Compared with the prior art the utility model has the following advantages: 1, simple in structure, low cost of manufacture, Easy to use; 2, flexible movements, quick, safe and reliable, do not damage surface of the work; Put when 3, using On securing member, need not take off, need not change other spanner until work complete; To generally being difficult to operation Securing member, this spanner all can operate, head can draw, before handle can push away.
