The rotation of the threaded rod 23 can drive the sliding block 21 to move up and down. When the index of the micrometer 3 returns to zero, the device can be placed on the top of the frame and ready to start testing.

[0035] During inspection, it is only necessary to push the entire device to move it horizontally to complete the flatness inspection. The flatness can be calculated by reading the data of the micrometer 3. When the measuring position needs to be adjusted, the adjusting block 61 can be toggled to the left to drive the inserting block 62 to disengage from the inner wall of the slot 63. At the same time, the adjusting block 61 will also drive the connecting plate 68 to move to the left. The connecting plate 68 moving to the left will drive the card block 69 to be inserted into the inside of the card slot 67. At this time, the device will not be able to move left and right. The operator can adjust the front and rear positions of the measuring point by toggling the sliding block 21. When the adjustment is completed, the adjusting block 61 can be toggled to the right to drive the inserting block 62 to be re-inserted into the inside of the slot 63 to re-fix the sliding block 21, and drive the card block 69 to be disengaged from the card slot 67 to release the roller 5.
