Description
Technical field
The present invention 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 by the bottom is movably arranged in the chute of fixing spanner, the bottom of sliding shoe is provided with diagonal pitch, 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 by the rotation of adjusting nut, thereby realize the chucking that will pull object or unclamp.But the action when regulating the spanner chucking and unclamping of this adjustable wrench is slower, and larger by the Gap-Ratios between the chucking object, can not well tighten the object that to 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 is provided with some anti-slip veins at locating piece, but because operating environment is complicated, often owing to occupy on hand greasy dirt or incrustation scale, so that anti-slip veins promotes locating piece is very inconvenient.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly can tighten fast, the gap is little, cut more easy-operating adjustable wrench.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: adjustable wrench, comprise: handle, the movable jaw that is arranged on the fixedly spanner on the handle and matches with fixing spanner, be provided with guide groove at fixing spanner, be provided with the sliding shoe that matches with guide groove at the movable jaw downside, 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, is provided with the groove that is meshed with the groove of sliding shoe bottom surface on the locating piece, and two groove engagement activity wrench can not outwards move, and also are arranged with spring on the alignment pin of locating piece lower end.
In order to solve the problems of the technologies described above better: also be provided with groove in the above-mentioned guide groove, be equipped with bearing pin at the sliding shoe with the groove correspondence position; Simultaneously, be provided with raised button on the locating piece, no matter so that working environment, can be so that the operator promotes locating piece like a cork.
Advantage of the present invention is: can realize that spanner and little, convenient to use by the gap between the card object is not easy the people is caused injury to pulling the quick chucking of object.
Description of drawings:
Fig. 1 is structural representation of the present invention;
Among the figure: 1, handle, 2, fixing wrench, 3, movable wrench, 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, raised button.
The specific embodiment:
As shown in the figure: adjustable wrench comprises: handle 1, the movable wrench 3 that is arranged on the fixedly wrench 2 on the handle 1 and matches with fixing spanner 2, be provided with guide groove 4 at fixing spanner 2, be 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, be equipped with bearing pin 13 at the sliding shoe 5 with groove 12 correspondence positions, the bottom surface of sliding shoe 5 is provided with groove 6, downside at guide groove 5 is provided with cavity 7, be provided with alignment pin 8 in the cavity 7, locating piece 9 is set on the alignment pin 8, be provided with the groove 10 that is meshed with the groove 6 of sliding shoe 5 bottom surfaces on the locating piece 9, and movable wrench can not outwards move after the engagement of two grooves, also is arranged with spring 11 on the alignment pin 8 of locating piece 9 lower ends, also is provided with some raised button 14 on the described locating piece 9.
The adjustable wrench of said structure is when work, the raised button 14 of at first pinning on the locating piece 9 with hand 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 is subject to locating piece 9 shrinks, make the groove 10 that is arranged on the locating piece 9 and be arranged in the process that sliding shoe 5 slides in guide groove 4, the bearing pin 13 that is arranged on the sliding shoe 5 also can slide in groove 12, and bearing pin 13 can come off from guide groove 4 by anti-skidding piece 5.Sliding shoe 5 slides laterally along guide groove 4, thereby increase movable jaw 3 and the fixing spacing between the spanner 2, with the object chucking that will pull, then, the hand of pinning locating piece 9 is unclamped, and 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 first hand be unclamped, make groove 10 and groove 6 intermeshing.Because the spacing between groove 6 and the groove 10 adjacent grooves is all smaller, so active spanner 3 reaches fixing spanner 2 and the gap that will pull between the object is also less, get the object card that to pull tighter.
