The worktable has circumferential graduations engraved around the groove. A rotatable disc is placed in the groove, and two clamping columns are placed on the disc. A clamping mechanism is fixed on the horizontal extension line between the two clamping columns and on the surface of the worktable. A driving mechanism that can drive the disc to rotate is provided below the disc and under the worktable.

[0004] The above method only measured the bending of the bellows in one direction, and lacked measurement for the bending of the bellows in multiple directions. Utility Model Content
