Description
The utility model belongs to a kind of hand-operated tools, particularly a kind of replaceable spanner of pulling mouth.
Usually the spanner of usefulness mainly contains following several: a kind of is that flower is pulled, there are several to pull the hole on the body pulling of template, it is suitable for the nut that turns plurality of specifications, but owing to respectively pull Kong Zaiyi the diverse location of pulling body, for the narrower nut in fixed position, easily interfere during operation, be difficult to sometimes play a role; Another kind is that the survivor of a murder attempt pulls, and pulls a mouthful adjustable size, and to pull mouthful size screw easily loosening but regulate, and pulls mouth and is difficult to nut is clamped, and the trigger piece pulled of the survivor of a murder attempt is longer in addition, and the nut of or specific position narrower for the fixed position also is difficult to play a role; Also have a kind of glasses spanner, one is with somely, and it is a crank, and every two ends have a different size to pull the hole, and shortcoming is that every during purchase, one is with tens only being applicable to two kinds of specifications of nuts, and price is more expensive.
The purpose of this utility model provides the spanner that a kind of replaceable different size is pulled mouth, and is easy to use, easy operating.
The purpose of this utility model is achieved in that it comprises the spanner of trigger piece and several different sizes, improved technical scheme main points are: there is circumferential locating hole the end of trigger piece, the part of spanner is a positioning section, this section inserts the circumferential locating hole of trigger piece, the positioning section of spanner is equipped with flexible positioning piece, and another part of spanner is mouthful section of pulling that band is pulled mouth.During use, choose the spanner that uses specification, pinch the flexible positioning piece on the spanner, the positioning section of spanner is inserted in the circumferential locating hole of trigger piece, decontrol flexible positioning piece then, spanner is not deviate from the circumferential locating hole of trigger piece, can use.When changing spanner, pinch flexible positioning piece, spanner can be extracted.
The utility model has the advantages that: can change the spanner of different size as required, easy to use, easy operating.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is embodiment 1 structural representation of the present utility model.
Fig. 2 is 1 vertical view.
Fig. 3 a, Fig. 3 b are the spanner schematic diagrames of two kinds of structures.
Fig. 4 is the flexible positioning piece structural representation.
Fig. 5 is the utility model embodiment 2 structural representations.
See Fig. 1-4, embodiment 1 structure: respectively there is a circumferential locating hole of interior hexagonal at trigger piece 3 two ends of crank-like, and the part of spanner is the outer-hexagonal positioning section, and this section can insert in the circumferential locating hole of trigger piece, another section of spanner is to pull a mouthful section, and shape adopts hollow interior hexagonal 2 and solid outer-hexagonal 4 respectively.The spanner of two kinds of shapes is loaded on the two ends of trigger piece 3 respectively.Two apertures 5 are arranged on the positioning section of spanner, and flexible positioning piece 1 is the stage clip 1 that two positioning convex 6 are arranged, and during assembling, the positioning convex 6 of stage clip 1 is entrapped in two apertures 5 on spanner 2,4 positioning sections, makes spanner 2,4 not deviate from the locating hole of trigger piece 3.During dismounting, pinch stage clip 1, make its distortion, the positioning convex 6 of stage clip 1 is deviate from the aperture 5 on spanner 2,4 positioning sections, and spanner can break away from trigger piece.See Fig. 5, embodiment 2 structures: there is an interior hexagonal directional hole trigger piece 3 actuating rod ends of T-shaped shape, and spanner is assembled in the directional hole of trigger piece 3 actuating rod ends, and the version of spanner is same as above, promptly adopt hollow interior hexagonal 2 and solid outer-hexagonal 4.
