Abstract
The invention discloses an adjustable spanner, which comprises a spanner body. An adjusting valve, a fixed jaw and a movable jaw are arranged on the spanner body, the adjustable valve can drive the movable jaw to move to be close to or far away from the fixed jaw, and graduations are arranged on the surface of the spanner body; a starting point of the graduations is flush with a plane of the inner side of the fixed jaw; three holes are disposed on a side wall, which is close to the movable jaw, of the spanner body; 'U'-shaped pins are inserted in any two of the holes; a positioning hole is arranged on the adjusting valve; and any one of the holes is flush with the positioning hole, and the sizes of the holes are identical to the size of the positioning hole. The distance from the fixed jaw to the movable jaw can be adjusted properly according to the graduations, so that the adjustable spanner can be directly used for nuts and bolts which need to be screwed, and can be used in a situation that an adjusting portion cannot be manually adjusted in a narrow space, and the adjusting portion cannot be loosened or slip easily during usage.
Description
Technical field
The present invention relates to a kind of monkey wrench, relate in particular to a kind of be adapted at saving with hand adjustment use in the narrow space of adjusting portion and adjusting portion is difficult for the monkey wrench that gets loose and skid.
Background technology
In machine-building and constructions work, usually there are a large amount of indefinite specifications of nuts and bolt need use various spanners to screw; Use the monkey wrench in the existing field of circulation, at first need reach the folder mouth between fixed jaw and the movable jaw greatly as much as possible, be close to fixed jaw one end of the object that is applied then; Regulate at last control valve make movable jaw at leisure near, make the distance of movable jaw and fixed jaw just equal to be applied the length of object, when nuts and bolt that needs are screwed is in the narrow space; Can't regulate the distance of fixed jaw and movable jaw; Cause monkey wrench not use, and in screwing operation, have the situation appearance that adjusting portion gets loose and skids; Cause the distance of fixed jaw and movable jaw that tiny change takes place, bring inconvenience to the user.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of be adapted at saving with hand adjustment use in the narrow space of adjusting portion and adjusting portion is difficult for the monkey wrench that gets loose and skid.
Technical solution of the present invention is achieved in that a kind of monkey wrench; Comprise wrench body; Said wrench body is provided with control valve, fixed jaw and movable jaw, said control valve can drive movable jaw do near or away from the moving of fixed jaw, said wrench body surface is provided with scale; The starting point of said scale is equal with the inner side plane of fixed jaw; The sidewall that said wrench body and movable jaw are close is provided with three holes; Be inserted with " U " shape pin in said any two holes; Said control valve is provided with locating hole; Said any hole aligns with locating hole and is big or small identical.
Preferably, said control valve equal intervals is provided with a plurality of locating holes.
Preferably, the both sides shank of said " U " shape pin is uneven in length.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Monkey wrench of the present invention, because the wrench body surface is provided with scale, the starting point of scale is equal with the inner side plane of fixed jaw; When nuts and bolt that needs are screwed is in the narrow space; Only need know the specification of nuts and bolt, regulate the distance between fixed jaw and the movable jaw, directly act on the nuts and bolt that to screw according to scale; It can be used in the narrow space that can not save adjusting portion with hand adjustment, not only improved operating efficiency but also enlarged its scope of application; In addition; In the process of screwing, in the hole that an end inserts and locating hole aligns with " U " shape pin, the other end inserts in remaining any hole; Can fix control valve; The situation that prevents to get loose and skid occurs, and makes that the distance of fixed jaw and movable jaw can change, and serviceability is improved.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the stereogram of monkey wrench of the present invention;
Accompanying drawing 2 is the user mode figure of monkey wrench of the present invention;
Wherein: 1, wrench body; 2, control valve; 3, fixed jaw; 4, movable jaw; 5, scale; 6, hole; 7, " U " shape pin; 8, locating hole.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of monkey wrench shown in accompanying drawing 1; Comprise wrench body 1; Said wrench body 1 is provided with control valve 2, fixed jaw 3 and movable jaw 4, said control valve 2 can drive movable jaw 4 do near or away from the moving of fixed jaw 3, said wrench body 1 surface is provided with scale 5; The starting point of said scale 5 is equal with the inner side plane of fixed jaw 3; Said wrench body 1 is provided with three holes 6 with movable jaw 4 close sidewalls; Be inserted with " U " shape pin 7 in said any two holes 6; The both sides shank of said " U " shape pin 7 is uneven in length; Said control valve 2 equal intervals be provided with a plurality of locating holes 8; Said any hole 6 aligns with locating hole 8 and is big or small identical.
Of the present invention a kind of monkey wrench shown in accompanying drawing 2; When nuts and bolt that needs are screwed is in the narrow space; At first need know the specification of nuts and bolt, regulate the distance between fixed jaw 3 and the movable jaw 4 according to scale 5 then, directly act on the nuts and bolt that to screw; It can be used in the narrow space that can not save adjusting portion 2 with hand adjustment, not only improved operating efficiency but also enlarged its scope of application.At ordinary times; " U " shape pin 7 is in not in two holes 6 that align with locating hole 8, after the distance that regulates between fixed jaw 3 and the movable jaw 4, " U " shape is sold 7 extract; One end of " U " shape pin 7 is inserted in the hole 6 that aligns with locating hole 8; The other end inserts in remaining any hole 6, makes that the distance of fixed jaw 3 and movable jaw 4 can change, and serviceability is improved.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
