Description
Technical field
The utility model relates to a kind of hand tools, is specifically related to a kind of convenient monkey wrench of regulating.
Background technology
In hand tools, the frequency that monkey wrench uses is quite high, can adjust the nut that openings of sizes adapts to multiple size because of it has, and not need to use instead according to the nut of different size the spanner of various openings, thereby bring bigger convenience and practicality.
In all hand tools, monkey wrench manufacture difficulty height, the precision of its requirement is higher, the also the most difficult control of its quality.The now present monkey wrench that uses, effect by screw rod, tooth bar, can regulate the openings of sizes of work jaw, but need unclamp, take out spanner from workpiece during return, press from both sides again after turning an angle then and go up workpiece, could continue to pull, the monkey wrench that has also is provided with spring mechanism, controls by stretching of spring when return.Because the wearing and tearing of screw rod, tooth bar, the issuable deformation of spring mechanism, after spanner uses a period of time become flexible easily, skid in inside, and this loosening and skid easily equipment is caused damage when operation.And pull when mouthful big or small in adjusting, will pull tooth bar with finger usually and accurately locate, and the tooth bar tight tooth bar that must press...with one's finger could guarantee that screw rod is loosening and skid that pull mouth and be not easy workpiece is clamped, these all make spanner be restricted when operation.
The utility model content
Need point size that accurate adjusting pulls mouthful, loosening deficiency of skidding easily during at monkey wrench of the prior art operation, the utility model provides a kind of simple and reliable, clamping work pieces that can be firm, the monkey wrench of high efficiency.
The technical solution of the utility model is achieved in that a kind of monkey wrench, comprise wrench body, be provided with moving spanner and decide spanner, decide spanner and fixedly connected with wrench body at the front end of wrench body, move spanner and decide formation work jaw between the spanner, moving spanner can move with respect to deciding spanner; It is characterized in that: described wrench body is provided with bearing pin, on bearing pin, be with band tooth spanner handle, band tooth spanner is being that the center of circle rotates to an angle with the bearing pin, and moving spanner and band tooth spanner are passing through gears engaged, and rotating band tooth spanner moves the spanner move left and right driving.
Further technical characterictic, the band tooth spanner of described monkey wrench is being provided with equally spaced double wedge, and moving spanner is provided with recessed tooth, and double wedge is corresponding with the position of recessed tooth, and tightens mutually by energy of rotation.
With respect to prior art, the utlity model has following advantage:
1, by accommodation zone tooth spanner handle, can control the size and the distance of spanner, because band tooth spanner is being circular gear structure, simple more, convenient when regulating, and band tooth spanner all has last each double wedge a groove corresponding with it on moving spanner, only need during adjusting the workpiece clamping is got final product, and need accurately not regulate with finger;
2, since band tooth spanner can with corresponding groove chucking on the moving spanner, therefore after pulling mouthful with the workpiece clamping, what groove can be firm tightens gear, can not skid and become flexible;
3, easy to use, because band tooth spanner is being circular configuration, very laborsaving when pulling, pull force is big more, and it is tight more to pull mouthful holding workpiece, has improved operating efficiency significantly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein, 1-moves spanner, and 2-decides spanner, 3-band tooth spanner handle, 4-bearing pin, the 5-jaw of working, the recessed tooth of 6-, 7-double wedge, 8-wrench body, 9-abaculus, 10-sliding tray.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Monkey wrench of the present utility model comprises wrench body 8, moving spanner 1 is set and decides spanner 2 at the front end of wrench body 8, decides spanner 2 and fixedlys connected with wrench body 8 or be set to one; Moving spanner 1 and decide to form work jaw 5 between the spanner 2 moves spanner 1 and can move with respect to deciding spanner 2, and the openings of sizes of work jaw 5 is changed, so as with cooperations such as different nut, spiral shell emits.On wrench body 8, the concrete center of wrench body 8 in the drawings, be provided with bearing pin 4, bearing pin 4 is fixedly installed on the wrench body 8, be with band tooth spanner 3 on bearing pin 4, band tooth spanner can be 3 that the center of circle rotates to an angle with bearing pin 4, and moving spanner 1 agrees with 3 by gear with band tooth spanner, rotating band tooth spanner can drive 3 decides spanner 2 move left and right, makes the openings of sizes of work jaw 5 produce respective change.
The band tooth spanner of described monkey wrench is provided with equally spaced double wedge 7 to 3, and moving spanner 1 is provided with recessed tooth 6, double wedge 7 setting that matches with recessed tooth 6, and its position is corresponding, and by the energy of rotation chucking that cooperatively interacts.Manual rotating band tooth spanner was 3 o'clock, and double wedge 7 corresponding rotations drive recessed tooth 6 and move, and made spanner 1 corresponding moving, thereby made work jaw 5 open or shrink.Firmly be provided with and tightened owing to decide spanner 2, when clamping work pieces, can not produce loosening or skidding, also do not need with the openings of sizes of pointing accurate adjusting work jaw 5, not only laborsaving but also can improve operating efficiency.
Moving spanner 1 and the respective outer side edges relation of decide spanner 2 are on moving spanner 1 abaculus 9 to be set, and are deciding to be equipped with sliding tray 10 on the spanner 2, and it is interior and be connected that abaculus 9 stretches into sliding tray 10; Pull band tooth spanner during work 3, abaculus 9 move left and right in the sliding tray 10 of deciding spanner 2 of moving spanner 1 makes work jaw 5 open or shrink.Especially at the band tooth spanner that turns clockwise 3 o'clock, moving spanner 1 moves near deciding spanner 2 to the right, the jaw 5 of working tightens up and clamping work pieces, pull force is big more, it is tight more to pull mouthful holding workpiece.
Monkey wrench of the present utility model can be used in four jiaos or hex bolts, when using monkey wrench, holds wrench body 8, pulls band tooth spanner 3, decides spanner 2 fixed-site, moving spanner 1 move left and right, and work jaw 5 opens or shrinks.When rotating band tooth spanner 3 the time, decide spanner 2 and band tooth spanner the recessed tooth 6 and double wedge 7 chuckings of contact portion on 3, and drive is decided spanner 2 and is moved.Turn clockwise band tooth spanner 3, and moving spanner 1 is to moving near deciding spanner 2 directions, and the jaw 5 of working tightens up, and clamping work pieces, pull force are big more, and it is tight more to pull mouthful holding workpiece; Be rotated counterclockwise band tooth spanner 3, decide spanner 2 away from moving spanner 1, work jaw 5 opens, and unclamps workpiece.
Invention can be implemented on the manually-operated spanner, also may be implemented on the spanner with power handle or operation automatically.
