Referring to the attached fig. 1 of the specification, a shielding cover 14 is sleeved on the outer side of the workbench 1, and a part of the front side of the rotating disc 42 is located on the outer side of the shielding cover 14.

The shielding cover 14 can cover the milling mechanism 2 and the sanding mechanism 3, prevent generated debris from sputtering and protect personnel safety.

Referring to the description of fig. 2, the lifting disc 47 is provided with a plurality of blocking rods 15 at the top, and the diameter of the top ends of the blocking rods 15 is smaller than that of the bottom ends thereof.

The blocking rod 15 can block and guide the workpiece, and prevent the workpiece from deflecting when the lifting disc 47 pushes the workpiece to lift.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
