A mounting seat 3 is provided at one end of the mounting member 1, and the mounting seat 3 is hollowed out to form a mounting channel 4, which is communicated with the adjustment channel 2, and a threaded structure is provided on the inner wall of the mounting channel 4. The mounting member 1 is fixedly mounted on the aircraft fire extinguisher bottle through the mounting seat 3, so that the object to be cut on the aircraft fire extinguisher bottle is set in the adjustment channel 2.

[0033] The other end of the mounting member 1 away from the mounting seat 3 is provided with a limiter 5, and a through-channel 6 is provided in the limiter 5, and the through-channel 6 is connected with the adjustment channel 2. A cutter bar 7 is provided through the through-channel 6, and one end of the cutter bar 7 is passed through the through-channel 6 to enter the adjustment channel 2.

A fixing member 9 is provided on the limiter 5, and the length of the cutter bar 7 extending into the adjustment channel 2 is fixed by the fixing member 9. When the fixing is completed, the distance between the milling cutter head 8 and the mounting seat 3 is further adjusted by adjusting the relative position between the limiter 5 and the fixing member 9, so that the milling cutter head 8 can accurately cut the object to be cut.
