The slider 43 is on the guide rail 41 and the slider 43 and the guide rail 41 are slidably connected. The top end of the base 42 is fixedly installed with a first mounting seat 44. The first rotating plate 46 is rotatably installed in the first mounting seat 44 through a first pin 45. A first fixing bolt 47 is installed on one side of the first mounting seat 44.

Observe the fit gap between the detection plate 76 and the workpiece to determine whether the width of the workpiece meets the standard. After confirmation, tighten the second fixing bolt 75 to fix the second rotating plate 73.

[0025] Align the hole marking pin assembly 83 with the hole to be inspected on the workpiece, insert the marking pin into the hole.
