Fixed, regulation axle outer end is in outside lens barrel, and regulation axle outer end is provided with plectrum knob.
As preferably, described in double the slidably direction level of microscope base, the hole depth direction of bar hole and regulation
Axle axially in parallel, the length direction of bar hole is vertical with the hole depth direction of bar hole, in the length of bar hole
On degree direction, bar hole is higher than bar hole one end away from pull bar near one end of pull bar.
The beneficial effects of the utility model are: rational in infrastructure, can effectively carry out the switching of light channel structure, tune
Joint amplification, and can quickly realize toggling, it is beneficial to observe contrast.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of duty of this utility model；
Fig. 2 is the structural representation of this utility model another kind duty；
Fig. 3 is the structural representation at this utility model switching construction.
In figure: lens barrel 1, reflecting optics 11, objective holder 2, object lens 21, eyepiece mount 3, double microscope base
41, eyeglass 42, pull bar 43, bar hole 44, regulation axle 45, plectrum knob 451, light hurdle 5 are doubled.
Detailed description of the invention
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, a kind of switchable light channel structure, including lens barrel 1, described lens barrel
Being provided with objective holder 2, eyepiece mount 3, objective holder is provided with object lens 21, is provided with for will be by thing in lens barrel
The incident illumination that microscope base is injected reflexes to the reflecting optics 11 of eyepiece mount, and reflecting optics is in below eyepiece mount,
Be provided with switching construction between eyepiece mount and reflecting optics, switching include can relatively lens barrel slip double microscope base
41, be arranged on double on microscope base double eyeglass 42, for drive double microscope base relative to drawing that lens barrel slides
Bar 43, doubles microscope base and is provided with bar hole 44, and pull bar one end is provided with to be stretched in bar hole and adds for pulling
Times microscope base pull axle, the pull bar other end is provided with regulation axle 45, and regulation axle is rotatably assorted with lens barrel.Described
Being provided with light hurdle 5 in lens barrel, light hurdle is between objective holder and reflecting optics.Light hurdle can eliminate veiling glare,
Ensure image quality.Path channels in described eyepiece mount is vertical and cylindrical, and eyepiece mount is by fixing spiral shell
Nail is fixed on lens barrel, fixing screw and lens barrel threaded engagement, fixing screw and eyepiece mount threaded engagement.
Described regulation axle is the most vertical with pull bar length direction, and regulation axle the inner is fixed with pull bar, regulates axle outer end
Being in outside lens barrel, regulation axle outer end is provided with plectrum knob 451.Stir rotation plectrum and can directly drive tune
Nodal axisn rotates.Double microscope base to be slidably connected with lens barrel.The described slidably direction level doubling microscope base, bar
