The structure of dynamic component parts is identical as positional relationship；
Driving first screw rod drives first steel ball described the by the first guiding slide bar
Moved in the V-groove of one vee-block, while first steel ball withstands the concave surface of the first adjustment plate, thus driving it is described the
One adjustment plate angles shifts；The lock on counterbore after the completion of angle adjustment, by being located at the first driving pedestal
Tight screw pulls the outer unthreaded hole part of the first driving pedestal to fasten the first guiding slide bar, makes first steel
Ball is static, so that the first adjustment described in keeping is stationary.It is adjusted by the second driving screw rod with identical principle adjustment second
The angle of whole plate, and lock and keep second adjustment plate stationary.
Technical effect of the invention:
1, the present invention has used guiding slide bar between screw rod and the steel ball of driving adjustment plate movement, by embracing in unthreaded hole
Tight guiding slide bar locks adjustment plate, and locking only has small radial motion when being oriented to slide bar, do not influence on adjustment plate, to protect
It is motionless the adjustment plate that adjustment is completed has been demonstrate,proved；
2, the upper and lower surface for being oriented to slide bar is all and sphere-contact that ensure that contact when guiding slide bar moves radially
Upper and lower component, screw rod and steel ball all remain stationary, and avoid the adjustment plate due to caused by the variation of screw rod during locking
It changes；
