[0027] Through the above structure, the driving worm 11 is rotated, and the driving worm 11 drives the driving worm wheel 4 meshing with it to rotate, and the driving worm wheel 4 drives the driving screw 5 connected to it to rotate. At the same time, since the movable plate 7 and the driving screw 5 are matched through threads, the movable plate 7 can move synchronously, the fixed frame 8 moves synchronously, the sliding plate 9 slides along the inspection box 1, and the connecting plate 12 moves synchronously. The distance between the connecting plate 12 and the scraper 23 changes. When the distance between the connecting plate 12 and the scraper 23 increases, the smear thickness thickens, and when the distance between the connecting plate 12 and the scraper 23 decreases, the smear thickness decreases. In addition, since the driving worm wheel 4 and the driving worm 11 have a self-locking function, the connection plate 12 can be placed more stably, thereby improving the accuracy of film making and the accuracy of detection.
[0028] Combined with Figure 3 And attached Figure 4 Both ends of the driving worm 11 extend out of the test box 1, and both ends of the driving worm 11 are provided with operating knobs 13. The operating knob 13 is provided with anti-slip strips 14, and multiple groups of anti-slip strips 14 are equidistantly arranged along the circumferential direction of the operating knob 13.
[0029] With the above structure, since the operating knobs 13 are provided at both ends of the worm, the driving worm 11 can be operated from two directions, thereby improving the convenience of operation.

[0031] Through the above structure, the elastic pressure strip 18 reacts to the glass slide through the elastic force generated by elastic deformation, thereby fixing the glass slide on the connecting plate 12, which is convenient for slide making.
[0032] Embodiment 2
[0033] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 4 And attached Figure 5 , both sides of the inspection box 1 are provided with limit rails 19, and a limit slider 20 is slidably provided on the limit rails 19, and a support arm 21 is provided on the limit slider 20, and a support frame 22 is provided on the support arm 21, and a connecting unit is provided on the support frame 22, and a scraper 23 is connected to the support frame 22 through the connecting unit, and the connecting unit includes a clamping screw 24 arranged on the support frame 22, and the clamping screw 24 is connected to the support frame 22 through a thread, and a clamping plate 25 is provided at one end of the clamping screw 24, and the clamping plate 25 abuts against the scraper 23, and a clamping knob 26 is provided at the other end of the clamping plate 25.
[0034] Through the above structure, the clamping knob 26 is rotated, and the clamping knob 26 drives the clamping screw 24 to rotate, and the clamping screw 24 drives the clamping plate 25 to move. When the clamping plate 25 abuts against the scraper 23, the scraper 23 is fixed. At this time, the scraper 23 can be driven to move by the support frame 22. With the cooperation of the support arm 21 and the limiting slider 20, the scraper 23 can slide along the direction of the limiting slide rail 19, otherwise the scraper 23 can be removed for cleaning.
[0035] Embodiment 3
[0036] Combined with Figure 1 To Attachment Figure 4 The test box 1 is provided with sample racks 15 at both ends, and the sample racks 15 are provided with placement holes 16 , and the placement holes 16 are arranged in multiple groups at equal intervals along the linear direction of the sample rack 15 .
[0037] Through the above structure, the sample can be conveniently placed on the sample holder 15, thereby improving the convenience of film making.
[0038] The specific usage is as follows:
[0039] The sample is placed on the placement rack, and the glass slide is fixed by the elastic pressure strip 18. The operating knob 13 is turned, and the operating knob 13 drives the driving worm 11 to rotate, and the driving worm gear 4 is driven to rotate. The driving worm gear 4 drives the driving screw 5 to rotate, and the movable plate 7 moves synchronously with the fixed frame 8. The sliding plate 9 drives the connecting plate 12 to slide along the inspection box 1, and the distance between the connecting plate 12 and the scraper 23 changes. When the distance between the connecting plate 12 and the scraper 23 increases, the smear thickness increases. When the distance between the connecting plate 12 and the scraper 23 decreases, the smear thickness decreases. The distance between the connecting plate 12 and the scraper 23 is adjusted as needed, and the scraper 23 is driven to move by the support frame 22. With the cooperation of the support arm 21 and the limiting slider 20, the scraper 23 slides along the direction of the limiting slide rail 19 to achieve film making.
