Operator can easily be held on hand lever, owing to hand lever is off on the rotating disk of setting, rotating disk can be driven to rotate convenient and smoothly, the final band smooth and easy rotation of dynamic(al) correction cylinder in shake hand lever process.
In the correcting unit of above-mentioned spring, between described positioning seat and drill chuck, there is bearing.
Drill chuck can be made under the effect of bearing to rotate smoothly.
In the correcting unit of above-mentioned spring, described location division takes the shape of the letter U, and the U-shaped opening part of described location division can by helical spring end clamping.
The coupler body of helical spring end can convenience and stable embedding location division place.
Alternatively scheme, in the correcting unit of above-mentioned spring, described location division is recessed bar-shaped trough, and described bar-shaped trough can by helical spring end clamping.
The hole no matter run through or recessed groove, as long as they coupler bodies in helical spring end match, can by helical spring end stable position.
In the correcting unit of above-mentioned spring, described hands handle has irregular annular knurl in round bar shape and at hands outside.
Frictional force can be increased, it is thus possible to rotate hands handle easily by concavo-convex annular knurl.
In the correcting unit of above-mentioned spring, described hands handle is integral type structure.
The handle structure of integral structure is compact.
In the correcting unit of above-mentioned spring, described frame having the support bar stretched out to its sidepiece, above-mentioned adjustable stem is hinged on support bar end.
Support bar, due to unsettled setting, reduces the height of whole correcting unit.
In the correcting unit of above-mentioned spring, having in plane contact site one on the upside of described support bar, described hands has the downside place at middle part in plane contact site two, above-mentioned hands the hinged place of frame between contact site one and contact site two.
Hands is big the hinged place contact area between support bar, it is thus possible to ensure both hinged stability.
Compared with prior art, the correcting unit of this spring can directly be positioned between correction cylinder and adjustable stem due to helical spring, and the handling of spring are more convenient, have significantly high practical value.
Meanwhile, having only to somewhat rotate correction cylinder in helical spring trimming process, correct operation is easy and quick.
