[0023] The present invention relates to a microscope which is convenient for changing the position of a lens, comprising a base 1, a mirror column 2 being fixedly connected to the surface of the mirror column 2, a mirror arm 3 being fixedly connected to the surface of the mirror arm 3, a lens barrel 4 being movably connected to the surface of the mirror arm 3, a reflecting mirror 5 being movably connected to the surface of the mirror arm 3, a rotating rod 6 being connected to the surface of the mirror arm 3 via a rotating shaft, a gear 7 being fixedly connected to the surface of the rotating rod 6, a rack 8 being meshed with the gear 7, a limiting plate 9 being fixedly connected to the surface of the rack 8, a limiting groove 10 being provided on the surface of the mirror arm 3, a movable groove 11 being provided on the surface of the mirror arm 3, a fixing screw 12 being connected to the surface of the rotating rod 6 via a thread, a connecting block 13 being fixedly connected to the surface of the rack 8, a universal ball 14 being fixedly connected to the end of the connecting block 13 away from the rack 8, a semi-spherical cover 15 being movably connected to the surface of the universal ball 14, a rotating frame 16 being fixedly connected to the end of the semi-spherical cover 15 away from the universal ball 14, a bolt being provided on the surface of the mirror column 2, and the mirror column 2 is fixed to the mirror arm 3 by bolts. A focusing screw is provided on the top of the mirror arm 3. By adjusting the focusing screw, the observed sample is clearer. Through the connection between the gear 7 and the rack 8, under the action of the swivel on the surface of the rotating rod 6, the gear 7 is synchronously driven to rotate when the rotating rod 6 rotates, thereby changing the up and down position of the rack 8, so that the position of the reflector 5 can be adjusted up and down, so that different samples can be observed more efficiently, which improves the convenience of use. The connection between the fixing screw 12, the rotating rod 6 and the mirror arm 3 is realized to fix the gear 7 and the rack 8, thereby ensuring the stability of the reflector 5 during work. The stability of the rack 8 is further guaranteed by the action of the limit plate 9, which prevents the rack 8 from shaking left and right. Through the connection between the universal ball 14 and the hemispherical cover 15, the angle of the reflector 5 can be changed up and down, left and right, thereby better adjusting the light source and greatly improving the convenience of use of this microscope.

[0024] Furthermore, a stage is provided on the surface of the mirror arm 3, and a pressure clamp is provided on the stage. The mirror arm 3 is connected to the mirror column 2 by bolts, the bottom of the mirror arm 3 is fixed to the mirror column 2 by bolts, the top of the mirror arm 3 is connected to the lens barrel 4, and the lens barrel 4 can make the object image clear through the focusing screw on the surface of the mirror arm 3.

[0025] Furthermore, a rotating shaft is provided inside the mirror arm 3, one end of the rotating rod 6 is connected to the rotating shaft, and a rotating ring is provided at the other end of the rotating rod 6. The rotating shaft is fixed inside the mirror arm 3. Through the connection between the rotating rod 6 and the rotating shaft, the staff can conveniently rotate the rotating rod 6 without worry or effort, thereby facilitating the rotation of the gear 7.

[0026] Furthermore, the rack 8 is plate-shaped and meshes with the gear 7, the limit plate 9 is strip-shaped and arranged on the surface of the rack 8, and the limit groove 10 is a rectangular groove opened on the surface of the mirror arm 3. The rack 8 moves up and down inside the limit groove 10, and a card slot is opened on the surface of the mirror arm 3. The limit plate 9 corresponds to the card slot. Through the connection between the gear 7 and the rack 8, when the rotating rod 6 rotates, it will synchronously drive the gear 7 to rotate, thereby changing the up and down position of the rack 8, so that the height of the reflector 5 can be adjusted, which is convenient for adjusting the height of the reflector 5 for different observation samples, greatly improving the convenience of using this microscope. By moving the rack 8 up and down inside the limit groove 10, the limit plate 9 and the card slot on the surface of the mirror arm 3 are left and right, so as to avoid the rack 8 from shaking left and right when moving up and down, thereby ensuring the stability of the light source at the reflector 5.

[0027] Furthermore, the movable groove 11 is a cylindrical groove opened on the surface of the mirror arm 3, the gear 7 moves in the movable groove 11, and the fixed screw 12 is a rod-shaped rod that passes through the rotating rod 6 and is connected to the mirror arm 3. Through the action of the fixed screw 12, the gear 7 is fixed, avoiding the gear 7 from sliding during operation, thereby ensuring the stability of the reflector 5 during operation.

[0028] Furthermore, the connecting block 13 is block-shaped and connected to the rack 8, the universal ball 14 is spherical and connected to the connecting block 13, and the hemispherical cover 15 is spherically sleeved on the surface of the universal ball 14. By connecting the connecting block 13 and the universal ball 14 to the rack 8, when the position of the rack 8 changes, the position of the connecting block 13 and the universal ball 14 are synchronously driven to change, thereby achieving the adjustment of the up and down position of the reflector 5. The hemispherical cover 15 is sleeved on the surface of the universal ball 14, and the surfaces of the universal ball 14 and the hemispherical cover 15 have their own resistance, which facilitates the angle adjustment of the hemispherical cover 15 and the reflector 5, thereby better adjusting the bright light source and greatly improving the accuracy of observation.

[0029] Furthermore, the rotating frame 16 is in a "C" shape and is connected to the hemispherical cover 15, and the reflector 5 is in a plate shape and is movably connected to the rotating frame 16. The reflector 5 moves up and down synchronously with the position of the rack 8. One side of the rotating frame 16 is connected to the hemispherical cover 15, and the other side of the rotating frame 16 is connected to the reflector 5. On the one hand, the reflector 5 is fixed, and on the other hand, the angle of the reflector 5 can be adjusted.

[0030] Working principle:

[0031] When working, first place the sample glass slide on the stage, press the sample glass slide with two sets of pressure clamps, then rotate the rotating ring on the surface of the rotating rod 6. At this time, the gear 7 rotates synchronously with the rotating rod 6, and the rack 8 starts to move up and down until the position of the reflector 5 is adjusted to the position that reflects the most light. Then tighten the fixing screw 12. At this time, the gear 7 and the rack 8 are firmly fixed. Then rotate the hemispherical cover 15 and the rotating frame 16 to adjust the angle of the reflector 5 to the optimal position of the light. Then adjust the focusing screw on the surface of the mirror arm 3 to start observing the sample. This ends here.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
