10. The method for using the split combined milling cutter assembly for end surface processing according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Selecting a suitable milling blade (603) according to the machining accuracy requirement of the workpiece end surface, and fixing the milling blade (603) to the fixing plate (601) by screws; S2, connect the knife handle (1) and the knife seat (3), insert the positioning block (212) into the square groove of the upper body (301), pull the unlocking handle (201) to move outward, the unlocking handle (201) moves outward to drive the locking block (205) to slide outward, the locking block (205) slides outward and disengages from the ratchet (206), and insert the hexagonal wrench through the clamping plate (5), the lower body (303), and the pad (302). ), the upper body (301) twists the twisting column (213) to rotate 90 degrees to one side, the twisting column (213) rotates 90 degrees to one side to drive the locking frame (208) to rotate 90 degrees to one side, the locking frame (208) rotates 90 degrees to one side to push the four sliding plates (209) to slide outward, and the sliding plates (209) slide into the square sliding grooves on the side of the square groove of the upper body (301), at which time the knife handle (1) and the knife seat (3) are fixedly connected; S3. When rough machining is performed on the end surface of the workpiece, the number of the cutter heads (6) is increased to eight, the check ring (401) is rotated counterclockwise to push the check ring (401) downward, the check ring (401) moves downward to push the sliding ring (402) to move downward, the sliding ring (402) moves downward to push the cutter head (6) to slide outward, after the cutter head (6) slides outward to a specified position, the check ring (401) is rotated clockwise, and at this time, the adjustment mechanism (4) increases the number of the cutter heads (6) to eight; S4. When finishing the end surface of the workpiece, when the four tool heads (6) are retracted, the check ring (401) is rotated counterclockwise to pull the check ring (401) upward. The check ring (401) moves upward to pull the sliding ring (402) upward. The upward movement of the sliding ring (402) drives the tool head (6) to slide inward.
