[0029] First, place the milling cutter to be inspected on the upper part of the workbench 1, start the motor 3 to drive the worm 4 to rotate, and the worm wheel 5 and the reciprocating threaded rod 6 rotate under the drive of the worm 4. At this time, the two threaded sleeves 7 move in opposite directions on the reciprocating threaded rod 6. The rotation of the reciprocating threaded rod 6 drives the two threaded sleeves 7 to move. Under the restriction of the slider 9 and the slide bar 8, the threaded sleeve 7 drives the fixed frame 11 connected by the moving block 10 to move, so that the two fixed frames 11 are close to each other;
