Description

A kind of spanner

Technical field

The utility model relates to operational instrument technical field, specially a kind of spanner.

Background technique

Spanner is widely used in the industries such as machinery overhaul, apparatus, household finishing, motor vehicle repair.It is mainly used for bolt Installation, disassembly, elastic operation.

Using spanner disassembly or when tightening nut, must by the opening at the top of spanner it is corresponding be inserted in elastic bolt or On the outer surface of nut, then switching pinch bar, it rotates nut around center axis, realizes the elastic of nut.But Using spanner knockout screw or nut, when the switching power of application is larger, spanner is easy to the axis direction along bolt or nut It falls off, dangerous phenomenon easily occurs.

Traditional class spanner corresponds to single work, when maintenance carries out simultaneously with test job, needs to carry a large amount of traditional classes Wrench increases operating personnel's labor intensity.To solve this problem, a kind of simple and convenient Multifunctional wrenching need to be developed Hand, reduces operating personnel's labor intensity, and spanner is not fallen off using safe.

Utility model content

The purpose of this utility model is to provide a kind of spanners, realize the elastic spiral shell with disassembly different model of a spanner Bolt, position is stablized, is not fallen off safely, easy to use.

To achieve the above object, the utility model provides the following technical solutions: a kind of spanner, including driving end and spanner Handle, for driving end at least provided with two groups, the side of driving end is provided with baffle, and the gear mouth an of U-shaped is opened up on baffle, keeps off mouth Opening direction pulls that the opening direction of mouth is consistent with half opening polygon on driving end, and one end of spanner handle is fixed with flywheel, and Driving end is distributed in the side wall annular of flywheel.

Preferably, the side length ratio that the minimum polygon of driving end pulls the side length of mouth and maxpolygon pulls mouth is 1:1- 1:10。

Preferably, there is a cavity on spanner handle, iron plate is placed in cavity.

Preferably, the minimum polygonal side length of iron plate and maxpolygon side length ratio are 1:1-1:10.

Preferably, 6 driving ends of the side wall annular spread of flywheel.

Preferably, the shape of half opening gear mouth (4) of the driving end (1) is regular hexagon and extends end opening.

Compared with prior art, the utility model has the beneficial effects that

1. by the way that flywheel is arranged on spanner, when flywheel is rotated to a direction, interchangeable size suitable work piece specification Driving end, entangle and rotated again to another direction after nut, realize elastic and disassembly；

2. the different driving end of multiple specifications is arranged by the side wall in flywheel, in order to realize the more function of spanner It can use, it can elastic and disassembly plurality of specifications workpiece；

3. being equipped with baffle by driving end, when progress bolt is elastic, the inside for pulling mouth is corresponding with the outer edge of nut Engagement, keeping off may pass through the stud matched to elastic nut and is not in contact with the screw thread cusp on stud in mouth, limit The play of spanner in the axial direction effectively prevents spanner and occurs spanner obscission in elasticity bolt.

4. being equipped with a cavity inside spanner handle, the half opening iron plate that specification is incremented by step by step can be placed in cavity, with Prevent that the specification with workpiece exact matching, the iron plate fitting of the suitable specification of selection are not placed on half-open when selecting driving end Mouth polygon is pulled in mouth, and the opening direction of iron plate is consistent with the opening direction for pulling mouth, realizes a driving end multifunctional use.

5. the utility model structure is simple, design rationally, is easy to use, improves stability and novelty, greatly increase Practicability.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of spanner, including driving end 1 and spanner handle 2, One end of spanner handle 2 is fixed with flywheel 6, and the different driving end 1 of multiple specifications is fixedly connected with annular spread in flywheel 6 Side wall exchanges the driving end to match with specification of workpieces to the rotation of direction by flywheel, entangle after screw and nut again to Elastic and disassembly is realized in the rotation of another direction.By the side wall in flywheel, the different driving end of multiple specifications is set, with It is easy to implement a wrench multifunctional to use, has baffle 3 on driving end 1, engaged with contacting with each other to elastic nut, baffle The gear mouth 5 of U-shaped half opening shape is presented in 3 oral area, and the opening direction and half opening polygon that keep off mouth 5 pull the opening direction one of mouth 4 It causes, half opening is pulled the medial surface of mouth 4 and is bonded with to elastic nut is corresponding when work, may pass through in gear mouth 5 to elastic nut It the stud 9 that matches and is not in contact with the screw thread cusp on stud 9, limits the play of spanner in the axial direction, effectively Prevention spanner occurs spanner obscission in elasticity bolt.

There is a cavity 7 on spanner handle 2, the half opening iron that specification successively decreases step by step and mutually coincide can be placed in cavity Piece 8, when the driving end not with specification of workpieces exact matching, the iron plate that can choose suitable specification is placed on half opening and pulls mouth 4 inside, the outside of iron plate 8 are fitted in the medial surface for pulling mouth 4, the opening direction of iron plate 8 and the opening direction phase one for pulling mouth 4 It causes, realizes a driving end multifunctional use.

Working principle:

The different driving end 1 of multiple specifications is fixedly connected with annular spread in the side wall of flywheel 6, by flywheel to one Direction rotation interchangeable selects the driving end to match with specification of workpieces, turns again to another direction after entangling stud and nut It is dynamic, realize elastic and demounting bolt.There is baffle 3 on driving end 1, is engaged with contacting with each other to elastic nut, the mouth of baffle 3 The gear mouth 5 of U-shaped half opening shape is presented in portion, and half opening is pulled the medial surface of mouth 4 and is bonded with to elastic nut is corresponding when work, gear mouth It may pass through the stud 9 matched to elastic nut in 5 and be not in contact with the screw thread cusp on stud 9, limit spanner Play in the axial direction effectively prevents spanner and occurs spanner obscission in elasticity bolt.It can in the cavity 7 of spanner handle 2 The half opening iron plate 8 that specification is different, mutually coincide is placed, it, can when the driving end not with specification of workpieces exact matching To select the iron plate for being suitble to specification to be placed on the inside that half opening pulls mouth 4, the outside of iron plate 8 is fitted in the medial surface for pulling mouth 4, iron The opening direction of piece 8 is consistent with the opening direction for pulling mouth 4, realizes a driving end multifunctional use.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
