Cylinder, lock pin, hole, T-shaped pin, lever, guide rail, slide bar connect composition.It is widely used in machine-building, the nut screwing clamping of repairing, pine
Open.
2, a kind of cone self-locking adjustable spanner (CN201579725U), is made up of quiet chuck, dynamic chuck, actuator, handle.Institute
The actuator stated moves chuck patch left handle and has bellmouth, is provided with cone in hole, and the actuator of cone left end is provided with button,
Spring one end connects in the middle part of cone, and on other end connecting handle, cone right part is provided with gear, and the handle answered with gear mesh is provided with tooth
Bar.It is widely used in the tightening of the nut mechanically of industry, building, agricultural, sphere of life, unclamps.
3, a kind of helical tooth self-locking adjustable wrench (CN201544158U), is made up of quiet chuck, dynamic chuck, actuator, handle.Adjust
Joint device is that chuck right lower quadrant is provided with helical teeth, and on quiet chuck right lower quadrant, fixing connection guide-rail plate, is provided with in guide-rail plate and its shape
The corresponding slide plate of shape, size, is provided with helical teeth below slide plate right part.It is widely used in industry, building, agricultural, forestry, life etc.
Every field machinery, the nut screwing clamping of equipment and unclamping.
Patent documentation disclosed above, although goal of the invention is similar with this utility model application, but equal in terms of technical scheme
Differ, do not interfere with the creativeness of this utility model application.
Utility model content
In place of the purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of self-locking moving spanner, pass through
The rotary disc locking structure of design, can make set screw lock, it is to avoid itself and the play of dynamic chuck straight-tooth.
This utility model solves technical problem and be the technical scheme is that
A kind of self-locking moving spanner, is made up of quiet chuck, dynamic chuck, set screw and handle, quiet chuck and handle one
Making, in quiet chuck, upper and lower gap is provided with dynamic chuck, and this dynamic chuck is shaped with outer straight tooth row in quiet chuck；In quiet chuck institute
Being provided with set screw in the cubic through hole of system, the set screw axle of this set screw lower end is by fastening screw on quiet chuck
Fastening, set screw is shaped with helical teeth, this helical teeth outer straight tooth row made with dynamic chuck is meshed, it is characterised in that:
It is shaped with one on the quiet chuck of set screw bottom set screw shaft position to slit hole, outside the set screw axle in this open-minded hole is shaped with
Screw thread, on this external screw thread, a rotating disk is installed in coaxial engagement.
And, the structure of described rotating disk is: rotating disk is shaped with female thread, the set screw axle of this female thread engagement set screw
Upper made external screw thread, by rotating rotating disk, positions set screw axle with quiet chuck.
And, the outer rim cylinder of rotating disk is shaped with form friction pattern.
Advantage of the present utility model and good effect be:
This spanner is shaped with a four directions through hole on quiet chuck, and the set screw axle in this through hole is pacified by screw-threaded engagement
Fill a rotating disk, it is achieved after set screw with the straight-tooth regulation of dynamic chuck, on the through hole of four directions, lock rotating disk by rotating disk,
So that set screw carries out locking location, it is to avoid the play of set screw and the straight-tooth of dynamic chuck so that dynamic chuck and quiet folder
Head realizes the location of opening；Whole design concept is ingenious, simple in construction, and processing ease is with low cost, is effectively increased operative employee
Work efficiency, be the regeneration product of existing adjustable wrench.
