[0016] 3. For the adjustable-angle tool microscope, by setting the flexible spring, the block and the arc rod, the flexible spring has a function of elastic recovery, which will make the left side of the block contact the right side of the arc rod again, and then play a fixing role on the arc rod, preventing deviation and improving the operation accuracy.

[0017] 4. For the adjustable-angle tool microscope, by setting the moving block, the lens barrel holder and the eyepiece, the moving block will drive the lens barrel holder to adjust the height, which is convenient for the operator to reach the best observation height and improve the use comfort.

At the bottom of the lens barrel frame 29, an objective lens 33 is fixedly installed. On the left side of the top of the base 1, a bottom plate 3 is fixedly installed. In the prior art, the bottom plate 3 and the top plate 4 respectively adopt two lead screws, so as to drive the product to move left and right and back and forth between the bottom plate 3 and the top plate 4. On the top of the bottom plate 3, a top plate 4 is fixedly installed. On the top of the top plate 4, a placement box 5 is fixedly installed. Inside the placement box 5, a first inner opening 16 is provided on the right side of the inner arc opening 12 and below the top opening 6. Inside the placement box 5, a second inner opening 17 is provided at the lower right of the first inner opening 16. Inside the second inner opening 17, a movable block 19 is movably sleeved. On the front of the movable block 19, a mounting shaft 23 is fixedly installed. The other end of the mounting shaft 23 passes through the inclined opening 18 and extends to the outside of the placement box 5 and is fixedly sleeved with a pulling block 24. On the left side of the movable block 19, an inclined rod 20 is fixedly installed. On the outer surface of the inclined rod 20, a flexible spring 22 is movably sleeved between the right side of the clamping block 21 and the inner wall of the placement box 5. One end of the flexible spring 22 is fixedly connected to the right side of the clamping block 21, and the other end of the flexible spring 22 is fixedly connected to the inner wall of the placement box 5. The other end of the inclined rod 20 penetrates through the placement box 5 and extends into the first inner opening 16 and is fixedly installed with a clamping block 21 inside the inner arc opening 12. The left side of the clamping block 21 is meshed and connected with the outer surface of the right side of the arc rod 13. On the front of the placement box 5, an inclined opening 18 is provided on the right side of the outer arc opening 11. On the top of the placement box 5, a top opening 6 is provided. On the left side of the inner cavity of the top opening 6, a side block 7 is fixedly installed. Inside the side block 7, a round shaft 8 is movably sleeved. One end of the front of the round shaft 8 penetrates through the placement box 5 and extends to the outside of the placement box 5. On the outer surface of the round shaft 8, a placement plate 9 is fixedly sleeved inside the top opening 6. On the left side of the top of the placement plate 9, a limiting block 10 is fixedly installed. The top end of the limiting block 10 is located above the placement box 5. On the front of the placement box 5, an outer arc opening 11 is provided below the right side of the round shaft 8. Inside the placement box 5, an inner arc opening 12 is provided below the top opening 6. At the bottom of the top opening 6, an arc rod 13 is fixedly installed inside the inner arc opening 12. The teeth on the right side of the arc rod 13 are adapted to the tooth openings on the left side of the clamping block 21. Inside the bottom end of the arc rod 13, a fixed shaft 14 is fixedly sleeved. One end of the front of the fixed shaft 14 passes through the outer arc opening 11 and extends to the outside of the placement box 5.A vertical rod 15 located outside the placement box 5 is fixedly sleeved between the outer surface of the fixed shaft 14 and the outer surface of the circular shaft 8.

[0027] During operation, the operator first places the product to be detected on the top of the placement plate 9 and makes the left side of the product contact the right side of the limit block 10. Then the operator rotates the knob 31, causing the driven gear 30 to drive the driven gear 27 and the lead screw 25 to rotate;

[0028] At this time, the moving block 28 will drive the lens barrel holder 29 to adjust the height. Then the operator can observe the product through the eyepiece 32. If the operator needs to observe the product obliquely, the operator first pulls the pulling block 24 at this time;

[0029] Thereby, the mounting shaft 23 drives the inclined rod 20 and the clamping block 21 to move through the movable block 19. At this time, the left side of the clamping block 21 will separate from the right side of the arc rod 13 and enter the interior of the first inner opening 16. At the same time, the operator pulls the vertical rod 15, causing the vertical rod 15 to drive the arc rod 13 and the placement plate 9 to rotate through the fixed shaft 14. At this time, the product on the top of the placement plate 9 will also rotate accordingly;

[0030] When the inclination angle of the product meets the requirements of the operator, the operator releases the pulling block 24 at this time. Due to the elastic recovery of the flexible spring 22, the left side of the clamping block 21 will contact the right side of the arc rod 13 again, thereby playing a fixing role on the arc rod 13;

[0031] Then the operator adjusts the position of the lens barrel holder 29 again to observe it.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
