[0003] For example, Chinese patent CN219724844U discloses a tapping machine for plate materials. The tapping machine includes a clamping assembly, a driving assembly, and a tap. The clamping assembly is used to fix the workpiece, and the driving assembly applies rotational force and axial pressure on the workpiece to cut the material, thereby forming a thread.

Since the box-shaped workpiece is folded upward on all sides, it is difficult to place the box-shaped workpiece on the worktable for tapping. Increasing the distance between the tap and the worktable will affect the tapping efficiency.
