The course of work and principle：When vertometer is not used, electromagnet 636 is not powered on, and check lock lever 638 is in the first spring
Under 637 elastic force effect, so that check lock lever 638 is stuck in locking slot 67, make spill spin block 631 that can not rotate, to lock stable machine
Structure 6 makes stabilizing mechanism 6 be protected in the case that device is not used, prevents non-operator stable operation mechanism 6, cause
Device damages, and when using vertometer, eyeglass is placed into the top center position of collimator objective 5 first, when video camera 4 incudes
When being placed on collimator objective 5 to eyeglass, electromagnet 636 is powered, and check lock lever 638 overcomes 637 elastic force of the first spring to close to electricity
The direction of magnet 636 is moved, and check lock lever 638 is made to be detached from locking slot 67, and a hand fixes eyeglass, and another hand holds spill spin block
631 and spill spin block 631 is made to rotate, T shapes round block 634 rotate to keep in T shapes circular groove 66 to protect when the rotation of spill spin block 631
The stabilization of rotation is held, while annular internal tooth item 633 is rotated with moving gear 641, and then lead screw 642 is driven to rotate, lead screw 642 rotates
Push plate 64 is set to be moved down in rectangular channel 68, when push plate 64 moves down, Buffer Unit 69 can be in the linkage of catch bar 610
It is moved to close to the direction of eyeglass under effect, when Buffer Unit 69 touches lens surface, the gradual stabilized mirror of steady rest 691
Piece, buffer bar 693 overcome the elastic force of second spring 696 to move up, and during 691 stabilized lenses of steady rest, work as pressure
When sensor 697 detects that the pressure value between steady rest 691 and eyeglass reaches setting value, continue to moving down for anti-thrust plate 64
Dynamic to make the pressure of eyeglass is excessive eyeglass is caused to damage, electromagnet 636 powers off, and makes check lock lever 638 in the elastic force of the first spring 637
It under effect, snaps into again in locking slot 67, to lock spill spin block 631, the effect of gag lever post 631 in the apparatus is to prevent
Two springs 696 make the disengaging dashpot 698 of buffer bar 693 carry out follow-up measurement process after eyeglass is fixed.
Based on above-mentioned, vertometer using the present invention fixing len holder, in fixing len, by stabilizing mechanism
Rotary components make Buffer Unit that eyeglass be fixed, since rotary components are to hold spill spin block by human hand to be rotated,
So that the drive component inside sliding cavity is moved, and then Buffer Unit is driven to move downward fixing len, does not need human hand and press downwards
Firmly fixing len holder, therefore eyeglass can be effectively prevent due to damage caused by rubber sleeve, also avoid that human hand dynamics is excessive to be made
Safety accident caused by being crushed at eyeglass.
As known by the technical knowledge, the present invention can pass through the embodiment party of other essence without departing from its spirit or essential feature
Case is realized.Therefore, embodiment disclosed above, all things considered are all merely illustrative, not the only.Institute
Have within the scope of the present invention or is included in the invention in the change being equal in the scope of the present invention.
