Abstract

The utility model relates to an adjustable wrench which comprises a middle wrench handle and wrench heads at two ends, wherein sexangular through holes are respectively formed at the outer end parts of the wrench heads at the two ends. The adjustable wrench is characterized in that the side edges at the outer ends of the two sexangular through holes are smaller than the opposite side edges at the inner ends of the sexangular through holes; a movable bar capable of moving horizontally is arranged in the middle wrench handle and the inner ends of the two wrench heads; both ends of the movable bar can movably extend and retract in the sexangular through holes; an outer side plane surface is arranged on one side of the movable bar, and is in sliding connection with inner side plane surfaces matched with the middle wrench handle and the connecting holes of the two wrench heads; a window hole is formed in the middle wrench handle; a rotatable adjusting wheel is arranged in the window hole; and the adjusting wheel is matched and connected with the threads in the middle of the movable bar in a sleeved manner. In the utility model, the ends of the movable bar are enabled to movably extend and retract in the sexangular through holes by rotating the adjusting wheel , so that the sexangular through holes of the two wrench heads can be used to fasten sexangular head fastening pieces of a plurality of specifications, and the adjustment is convenient.

Description

Adjustable spanner

Technical field

The utility model relates to a kind of tool wrench that hexagonal-head fastener is used of pulling, especially a kind of adjustable spanner.

Background technology

Existing pull the tool wrench that hexagonal-head fastener uses and be divided into monkey wrench and back-up wrench two big classes usually, back-up wrench generally is made up of middle trigger piece and two ends spanner, be fixed with the spanner with a certain specification securing member turret head coupling in the spanner of two ends respectively, its advantage is that volume is little and use light and handy than monkey wrench.But, because being suitable for specification, all fixes the two ends spanner on the back-up wrench, can not be adjustable as monkey wrench, and at work if fastening a plurality of different size hexagonal-head fastener, it is standby to carry a plurality of specification back-up wrenches.Therefore, the non-adjustable shortcoming that back-up wrench exists, it is standby to carry a plurality of specification back-up wrenches when making application.

Summary of the invention

The utility model provides a kind of adjustable spanner that hexagonal-head fastener is used of pulling for solving the shortcoming of above-mentioned prior art, makes it can be suitable for fastening a plurality of specification hexagonal-head fastener, and easy to adjust.

The technical solution adopted in the utility model is: a kind of adjustable spanner, and trigger piece and two ends spanner in the middle of comprising, spanner outer end, two ends is provided with the hexagonal through hole respectively, it is characterized in that: two hexagonal through hole outer end sides are all less than its relative inner side; In the middle of but a motion bar of move left and right is located in trigger piece and two spanner the inners, and the motion bar termination all can be in the hexagonal through hole moving telescopic; Motion bar is provided with outer side plane on one side, and this outer side plane is slidingly connected with the inner side plane that middle trigger piece and two spanner connecting holes cooperate; Be provided with fenestra in the middle trigger piece, be provided with rotatable regulating wheel in the fenestra, the threaded engagement socket in the middle of regulating wheel and the motion bar.

Further, in the connecting hole of trigger piece and two spanner the inners, wherein an axle sleeve was provided with inner side plane in the middle of described motion bar both sides were connected in by axle sleeve respectively, and with motion bar on corresponding inner side plane slide and join.And trigger piece and two spanners are inner in the middle of described is flexible connection.Can make processing more convenient like this.

The utility model beneficial effect is: it in use, make motion bar termination moving telescopic in spanner hexagonal through hole by rotating regulating wheel, thereby it is regulate the hexagonal through hole of two ends spanner, make it to be suitable for fastening a plurality of specification hexagonal-head fastener, and easy to adjust.

The specific embodiment

Description of reference numerals: hexagonal through hole 1, spanner 2, motion bar 3, middle trigger piece 4,, regulating wheel 5, fenestra 6, axle sleeve 7, hexagonal through hole outer end side 8.

The utility model is described in further detail below in conjunction with accompanying drawing:

With reference to accompanying drawing: this a kind of adjustable spanner that is used to pull hexagonal-head fastener such as hex nut and bolt, trigger piece 4 and two ends spanner 2 in the middle of comprising, spanner 2 outer ends in two ends are provided with hexagonal through hole 1 respectively, it is characterized in that: two hexagonal through hole outer end sides 8 are all less than its relative inner side; In the middle of but a motion bar 3 of move left and right is located in trigger piece 4 and two spanners, 2 the inners, and motion bar 3 terminations all can be in hexagonal through hole 1 moving telescopic; Motion bar 3 is provided with outer side plane on one side, and this outer side plane is slidingly connected with the inner side plane that middle trigger piece 4 and two spanners, 2 connecting holes cooperate; Be provided with fenestra 6 in the middle trigger piece 4, be provided with rotatable regulating wheel 5 in the fenestra 6, the threaded engagement socket in the middle of regulating wheel 5 and the motion bar 3.When it uses, rotate regulating wheel and make motion bar termination moving telescopic in spanner hexagonal through hole, regulate the fastening hexagonal-head fastener of the adaptive needs of hexagonal through hole of spanner use side, motion bar one end is with butt securing member one side in the use.

In the connecting hole of trigger piece 4 and two spanners, 2 the inners, wherein an axle sleeve 7 was provided with inner side plane in the middle of described motion bar 3 both sides were connected in by axle sleeve 7 respectively, and with motion bar 3 on corresponding inner side plane slide and join.Can make production and processing more convenient like this.

Gluing flexible connection can be adopted in trigger piece 4 and two spanners, 2 the inners in the middle of described, and at the attached cover garment bag of two connecting portion appearances.

The hexagonal through hole 1 of described two spanners 2 outer ends back-up wrench routinely is made as small one and large one equally respectively, can be suitable for more a plurality of specification hexagonal-head fastener like this, but and at the motion bar undergauge of little hexagonal through hole end.In addition, the thickness of two ends spanner 2 external end heads makes when using more convenient less than its inner.

What should be understood that is: the foregoing description is just to explanation of the present utility model, and any innovation and creation that do not exceed in the utility model connotation scope all fall within the protection domain of the present utility model.
