[0043] The base plate 101 is fixed to the worktable by the support leg 10, and the positioning plate 9 is installed into the through groove as the reference surface for the machining of the pole column.

[0044] The adjustment assembly 2 includes a connecting plate 201. A stepper motor 202 is fixedly mounted on the outer surface of the connecting plate 201.
