Times stereomicroscope.
Background technology
Common stereomicroscope more by the way of continuous zoom, be in the multiplying power scope of microscope itself, from
For most low power to being electrodeless continuous zoom between most high power, any multiplying power that can be in multiplying power scope observes sample, this change
The zoom mechanism of times mode is relatively complicated, and the accuracy of zoom mechanism requires higher, thus production cost is also higher；But
In different use environments, user only needs to observe the integral part of sample, is then adjusted to the details of high power observation sample
Can, the patent " rotating disc type Switch-zoom stereomicroscope " of my company（Number of patent application：201621039221.0）Can be with
Meet the needs of this respect, but the mode of its zoom is more special, and the people that rigid connection touches this stereomicroscope may be unaware that it
It is how to carry out zoom；Thus the utility model devises this handwheel two according to the use habit of stereomicroscope user
Shelves zoom stereomicroscope, meets the use habit of stereomicroscope user, and first user uses accessible.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of handwheel Switch-zoom stereomicroscope, according to stereoscopic
The use habit of microscope user and design, easily can be changed using handwheel between low power and high power, user
The integral part of sample can be observed with low power, then rotates microscopical handwheel, it is possible to is easily adjusted to high power
Observe the detail section of sample.
The utility model solve its technical problem the technical scheme adopted is that stereomicroscope Front-end Design one
Individual discoid rotation objective holder 9, when microscope is in the state of low power, left light path passes through left low power objective group 11, a left side
Deviation mirror 7, left interpupillary distance adjustment barrel 2 and left eyepiece 1；The right light path is adjusted by right low power objective group 12, right turn mirror 15, right interpupillary distance
Save cylinder 20 and right eyepiece 21, the imaging of sample when at this moment observer is observed that low power by left and right eyepiece；When needing to see height
Times when, rotate microscopical left zoom handwheel 5 or right zoom handwheel 17, at this moment left light path passes through left high power objective group 22, left
Deviation mirror 7, left interpupillary distance adjustment barrel 2 and left eyepiece 1；The right light path is adjusted by right high power objective group 23, right turn mirror 15, right interpupillary distance
Save cylinder 20 and right eyepiece 21, the imaging of sample when at this moment observer is observed that high power by left and right eyepiece.
Beneficial outcomes of the present utility model are that the handwheel Switch-zoom stereomicroscope is according to stereomicroscope user's
Use habit and design, can using easily can be changed during the stereomicroscope using handwheel between low power and high power
Promptly to observe the detail section of the integral part of sample and sample, transformational structure is relatively easy, and meeting stereomicroscope makes
The use habit of user, first user use accessible.

Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, in one discoid rotation objective holder 9 of Front-end Design of stereomicroscope, thing is rotated
Microscope base 9 is connected by rotating shaft 14 and locking nut a13 with main body 8, and rotating objective holder 9 can rotate relative to main body 8, and rotate thing
Stopper slot on microscope base 9 makes rotation objective holder 9 to rotate 90 °；Rotate the lower end of objective holder 9 and be mounted with left low power objective group
11, right low power objective group 12, left high power objective group 22, right high power objective group 23；Left low power objective group 11, right low power objective group 12
The line of centres and left high power objective group 22, the line of centres of right high power objective group 23 be in 90 °, and the center of this four objective lens
Rotate 9 same circumference of objective holder on place, it is ensured that rotate objective holder 9 rotate 90 ° can be switched to from low power high power or
Person is switched to low power from high power；The upper end of rotating shaft 14 is mounted with a gear 3, and gear 3 is with being arranged on conversion gear fixed plate 18
On conversion gear 4 engage, and conversion gear 4 passes through its fan-shaped toothed portion and the sector gear 16 in the zoom wheel rotating shaft 6
Engagement, by the left zoom handwheel 5 for rotating the both ends of zoom wheel rotating shaft 6 or right zoom handwheel 17, form sector gear 16, conversion tooth
Wheel 4, the engaged transmission of rotate gear 3, so as to drive rotating shaft 14 to rotate, and then make rotation objective holder 9 rotate, final to drive
Four objective lens carry out zoom；When microscope is in the state of low power, left light path passes through left low power objective group 11, left steering
Mirror 7, left interpupillary distance adjustment barrel 2 and left eyepiece 1；The right light path passes through right low power objective group 12, right turn mirror 15, right interpupillary distance adjustment barrel
20 and right eyepiece 21, the imaging of sample when at this moment observer is observed that low power by left and right eyepiece；When needing to see high power,
Rotate left zoom handwheel 5 or right zoom handwheel 17 turns over 90 °, at this moment left light path passes through left high power objective group 22, left steering mirror
7th, left interpupillary distance adjustment barrel 2 and left eyepiece 1；The right light path passes through right high power objective group 23, right turn mirror 15, right interpupillary distance adjustment barrel 20
With right eyepiece 21, the imaging of sample when at this moment observer is observed that high power by left and right eyepiece；If now switch back into low
Times, then opposite direction makes left zoom handwheel 5 or right zoom handwheel 17 rotate 90 °.
