When the mounting frame moves, the connecting door opens, and a part of the milling cutter on the placement assembly just extends out of the placement box. At this time, the milling cutter is taken out by controlling the processing arm on the milling machine. When different milling cutters need to be connected, the second motor can be driven to drive the placement assembly to rotate, and then the appropriate milling cutter is connected through the processing arm.

[0012] Beneficial effects obtained:

[0013] First, a first motor and a mounting frame are provided, and the first motor can effectively drive the mounting frame to slide in the placement box, so that subsequent tool change is convenient.

[0014] Secondly, a second motor and a placement assembly are provided, and the placement assembly can be effectively driven to rotate by the second motor to replace and install different milling cutters.
