Abstract
The invention relates to a screwing type tubular and adjustable dual-use wrench. The screwing type tubular and adjustable dual-use wrench comprises a central body and a turn handle body, wherein the central body is turnably mounted in the turn handle body, a first radial sliding groove is formed in the central body, a clamping block is slidably inserted into the first radial sliding groove, elastic-ball shallow holes are formed in the outer end face of the clamping block, elastic balls are mounted in the elastic-ball shallow holes, ejecting springs are arranged between the clamping block and the central body, and curved-face depressions are formed in the inner circle of the turn handle body and are matched with the elastic balls; when the turn handle body is turned, the clamping block is forced to do centripetal movement along the first radial sliding groove of the central body due to the radial rising/falling of the bottom faces of the curved-face depressions, so that a workpiece is clamped, and a force is applied to turn. The screwing type tubular and adjustable dual-use wrench can be used for screwing hexagonal nuts and bolts and can also serve as a pipe wrench after a pitching mechanism electroplated with a diamond clamping layer face is arranged, thereby being multifunctional.
Description
Technical field
The present invention relates to a kind of five metals hand-operated tools, the present invention especially relates to a kind of screwing type pipe combination wrenches alive.
Background technology
Pipe vice and adjustable nut spanner, invented respectively in 1888 and 1892 by Swede's outstanding Chinese Peter Claes Johanson, and obtain patent right.So far this kind of pipe vice and adjustable wrench (being called for short pipe combination wrenches alive) remain a kind of and use industry widely, civilian hand-operated tools.
Pipe vice is the hand-operated tools of twisting pipe.Be widely used in aqueous vapor oil pipe, oil drill rocker, the stubborn of geologic drilling rod revolve in operation.Kind has tube pliers, moral formula pipe vice, olecranon pipe twist, chain pipe tongs, multi-block type free pliers etc.Plain end pipe clamps, and is all angle fixture block, after jaw is adjusted to required size, rides and is clipped on workpiece and plus-pressure, then make it rotate by another power.The pipe vice improved, some adopts the clamp mode of lever principle, also has and adopts Hafu-type clamping structure, must maintain the existence of this power when this kind of pipe vice rotates; Chain pipe tongs must allow tool link walk around workpiece, could overlap and clamp workpiece, and it is very not convenient to use.These twist the hand-operated tools of pipe, do not leave the category of " pincers " all the time.
Adjustable wrench, constantly improving through people though long-term, total difficulty crosses over such technological difficulties, its clamping function problem that Here it is.Adjustable wrench one class instrument only has the function of adjusting jaw distance, does not have the mechanism of clamping work pieces.The adjustable wrench improved, the general regulative mode focusing on jaw distance, cannot accomplish the clamping of real connotation.Also there is the clamp mode adopting lever principle, but the existence of this power must be maintained when rotating simultaneously.What also have is designed to hook-shaped formula of pawl etc. by jaw.
Box spanner, fork spanner, double offset ring spanner etc., all only have fixing opening size.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of structure screwing type pipe that is simple, easy to use, that workpiece can be carried out radial clamping combination wrenches alive.
According to technical scheme provided by the invention, described screwing type pipe combination wrenches alive, it comprises centerbody and turning handle body, and centerbody is rotatably installed in turning handle body, and centerbody offers the first radial groove, in the first radial groove, sliding plug has clamp, the outer face of clamp offers marble shallow bore hole, in marble shallow bore hole, marble is installed, between clamp and centerbody, is provided with ejector spring, the inner circle of turning handle body offers curve recess, and curve recess coordinates with marble; When turning handle body rotates, the lifting of the radial direction of curve recess bottom surface, forces first radial groove of clamp centrally on body and does centripetal movement, thus clamping work pieces, and then afterburningly rotates.
The bus of described curve recess be one section of circular arc on off-centre operation or one on the central angle of correspondence, its radius has the curved section of eustasy.
Described circular arc or central angle corresponding to curved section are greater than 20 ° and are less than 50 °, and this circular arc or the lifting journey of curved section to spanner central point are greater than 1.5 is less than 6.
The bus of described concave curvature is two-way, is namely symmetrical two lines.
The inner end of clamp offers the first V-type groove, and it is the electroplated diamond layer sword that the V-arrangement face of the first V-type groove is provided with.
Centerbody offers the second radial groove, in the second radial groove, sliding plug has regulating block, and the center of the orientation of its axis centerbody of regulating block, is rotatablely equipped with rotating shaft in the centerbody of regulating block side, have regulating wheel at rotating shaft upper sliding sleeve, regulating block and regulating wheel pass through screw-threaded engagement.
Regulating block inner end on offer the second V-type groove, it is the electroplated diamond layer sword that the V-arrangement face of the second V-type groove is provided with.
Described centerbody is open type or closed type.
On the cylindrical of centerbody or offer the spring groove of circular arc in the inner circle of turning handle body, turning handle body or centerbody are fixed with straight pin, straight pin protrudes from the medium position of spring groove, in the spring groove of straight pin both sides, be provided with back-moving spring.
Revolving force is changed into the design of the clamp system of radial load by the present invention, make adjustable wrench be provided with clamping function, hex nut and bolt can not only be twisted, after configuration is electroplate with the distance adjustor of diamond clamping aspect, can also use as pipe vice, the multi-functional use of a kind of instrument.Clamp system and the combination of distance adjustor being electroplate with diamond clamping aspect are the simple and effective clamping structures to circular pipe fitting, become a kind of can the bulldog wrench of one-handed performance.Omit the simplified design of distance adjustor, compare with box spanner, double offset ring spanner, in the clamp state rotational workpieces, be more suitable for powerful twisting and revolve.
The present invention is cylinder head bolt, promoting the use of of round nut provides novel stubborn lathe turner's tool.
