Description
Technical field:
The utility model relates to the adjustable wrench in the hardware & tools.
Background technology:
Existing adjustable wrench mainly comprises: handle; Be arranged on fixedly spanner and the fixing movable jaw that matches of spanner on the handle; The sliding shoe of movable jaw through the bottom is movably arranged in the chute of fixing spanner, and the bottom of sliding shoe is provided with diagonal pitch, and the adjusting cavity fixedly also is set on the spanner; Regulate in the cavity and be provided with adjusting nut, adjusting nut matches with diagonal pitch.Regulate monkey wrench and the fixing spacing between the spanner through the rotation of adjusting nut, thus realize to pull the chucking of object or unclamp.But the action when regulating the spanner chucking and unclamping of this adjustable wrench is slower, and bigger by the gap between the chucking object; Can not well tighten the object that will pull; Firmly excessive when if the people pulls spanner, spanner can often come off, and easily operating personnel is damaged.In addition, existing adjustable wrench with the sliding shoe of groove correspondence position on the bearing pin that wears very easily damage or come off, make that the slip of movable jaw is smooth.
Summary of the invention:
The utility model technical problem to be solved provides and a kind ofly can tighten fast, the gap is little, smooth adjustable wrench slides.
The purpose of the utility model realizes through following technical scheme: adjustable wrench comprises handle, the movable jaw that is arranged on the fixedly spanner on the handle and matches with fixing spanner; Fixedly spanner is provided with guide groove, is provided with the sliding shoe that matches with guide groove at the movable jaw downside, and the bottom surface of sliding shoe is provided with groove; Downside at guide groove is provided with cavity; Be provided with alignment pin in the cavity, locating piece is set on the alignment pin, and locating piece is provided with the groove that is meshed with the groove of sliding shoe bottom surface; And two grooves engagement movable jaw can not outwards move, and on the alignment pin of locating piece lower end, also is arranged with spring.
In order to solve the problems of the technologies described above better: also be provided with groove in the above-mentioned guide groove, with the sliding shoe of groove correspondence position on be equipped with slider bar, the slider bar size is corresponding with groove, and can on groove, slide; Also be provided with some anti-skidding lines on the described locating piece.
The utility model has the advantages that: can realize to pull the quick chucking of object, spanner and little by the gap between the card object, the slip of slider bar in groove is smooth, convenient to use more, is not easy the people is caused injury.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Among the figure: 1, handle, 2, fixing spanner, 3, movable jaw, 4, guide groove, 5, sliding shoe, 6, groove, 7, cavity, 8, alignment pin, 9, locating piece, 10, groove, 11, spring, 12, groove, 13, slider bar, 14, anti-skidding line.
The specific embodiment:
In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is done further to detail below, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Show a kind of adjustable wrench of the utility model like Fig. 1: comprise handle 1; The movable jaw 3 that is arranged on the fixedly spanner 2 on the handle 1 and matches with fixing spanner 2, fixedly spanner 2 is provided with guide groove 4, is provided with the sliding shoe 5 that matches with guide groove 4 at movable jaw 3 downsides; Also be provided with groove 12 in the described guide groove 4; With the sliding shoe 5 of groove 12 correspondence positions on be equipped with slider bar 13, the bottom surface of sliding shoe 5 is provided with groove 6, is provided with cavity 7 at the downside of guide groove 5; Be provided with alignment pin 8 in the cavity 7; Locating piece 9 is set on the alignment pin 8, and locating piece 9 is provided with the groove 10 that is meshed with the groove 6 of sliding shoe 5 bottom surfaces, and two grooves engagement back movable jaw can not outwards move; On the alignment pin 8 of locating piece 9 lower ends, also be arranged with spring 11, also be provided with some anti-skidding lines 14 on the described locating piece 9.
The adjustable wrench of said structure is when work; The anti-skidding line of at first pinning on the locating piece 9 with hand 14 is left behind locating piece 9; Be set in spring 11 on the locating piece 9 lower end alignment pins 8 owing to the pressure that receives locating piece 9 shrinks; Make the groove that is arranged on the locating piece 9 10 and be arranged in the process that sliding shoe 5 slides in guide groove 4, the slider bar 13 that is arranged on the sliding shoe 5 also can slide in groove 12, and slider bar 13 can prevent that sliding shoe 5 from coming off from guide groove 4.Sliding shoe 5 slides along guide groove 4 laterally, thereby increases movable jaw 3 and the fixing spacing between the spanner 2, and the object that institute will be pulled tightens; Then; Open pinning the openhanded of locating piece 9, spring 11 is meshed with groove 6 locating piece 9 jack-up with groove 10; Like this, locating piece 9 just blocks movable jaw 3 location.In addition, before promotion sliding shoe 5 slides to the inside, also can open openhanded earlier, groove 10 and groove 6 are meshing with each other.Because the spacing between groove 6 and the groove 10 adjacent grooves is all smaller, thus active spanner 3 reach fixing spanner 2 and the gap that will pull between the object also less, with the object card that will pull get tighter.
