[0038] The fixing mechanism is fixedly connected to two sides of the detection platform 2.

[0039] The staff places the plastic sheet to be inspected on the top of the inspection platform 2, and then rotates the knob 26 so that the knob 26 drives the bolt 25 to rotate inside the screw groove 22, driving the clamping block 24 to move downward, and then moves the cylindrical block 21 to make the second rectangular block 20 slide inside the rectangular groove 19. When sliding to the top of the plastic plate, the knob 26 is rotated in the reverse direction to fix the second rectangular block 20 at this position, and then the drive motor 10 is started. The drive motor 10 drives the spiral shaft 11 to rotate so that the screw groove block 12 drives the first rectangular block 17 to move downward, driving the detection head 30 to contact the plastic sheet for detection.

[0040] By rotating the knob 26, the bolt 25 rotates inside the screw groove 22 to drive the clamping block 24 to move downward, and the second rectangular block 20 is moved to a suitable position and then rotated in the reverse direction to fix it, and then the drive motor 10 is started for detection.
