A type of window milling cone

Abstract

This utility model provides a window-opening milling cone, comprising: a milling cone base and a milling cone head with a mounting ring at the top. The mounting ring has a slot on its side, and the outer wall of the milling cone base has a through groove. A retaining plate is rotatably mounted inside the through groove, and a limiting plate is provided on the first side of the retaining plate. The mounting ring can be inserted from the bottom end of the through groove, allowing the limiting plate to enter the groove and slide in contact with it. The retaining plate is also engaged with the groove by rotation. This utility model enables a detachable connection between the milling cone base and the milling cone head. When the milling cone head is damaged due to grinding, it can be replaced separately, reducing the maintenance cost of the window-opening milling cone.
