The boring tool rod 121 is partially perpendicular to the upper surface of the composite cutter disc 110 and embedded in the composite cutter disc 110. The boring blade 120 is detachably connected to the end of the boring tool rod 121 away from the composite cutter disc 110. Different boring tool rods 121 can be replaced to realize the processing of gas cylinder bottle mouths 11 with different inner hole diameters, and different bottle mouth threads can be processed.

[0034] An outer cylindrical tool seat 141 and a chamfering tool seat 131 are provided on the composite cutter disc 110. The lower surface of the outer cylindrical tool seat 141 is connected to the upper surface of the composite cutter disc 110, and the lower surface of the chamfering tool seat 131 is connected to the upper surface of the composite cutter disc 110. The chamfering tool seat 131 and the outer cylindrical tool seat 141 are respectively located on both sides of the boring tool rod 121 along the radial direction of the composite cutter disc 110.

[0035] An outer cylindrical tool holder 141 is embedded with an outer cylindrical tool rod 142 at one end away from the composite cutter disc 110. The outer cylindrical tool rod 142 is perpendicular to the upper surface of the outer cylindrical tool holder 141 and is detachably connected to the outer cylindrical tool holder 141. The outer cylindrical blade 140 is detachably connected to the end of the outer cylindrical tool rod 142 away from the outer cylindrical tool holder 141.
