A milling cutter for making a key that extends laterally into a lock bore as defined in claim 1, wherein: the upper end of the transmission shell (1) is fixedly provided with a shell fixing plate (11), a plurality of centrosymmetric fixing plate mounting holes (12) are formed in the shell fixing plate (11), and the fixing plate mounting holes (12) are fixedly connected with a motor shell.
9. A milling cutter for making a key that extends laterally into a lock bore as defined in claim 1, wherein: the upper end of transmission shaft (2) is in the top of spacing subassembly (10) is connected with transmission shaft installed part (13), set up symmetrical transmission shaft mounting groove (14) on transmission shaft installed part (13), transmission shaft mounting groove (14) and the output fixed connection of motor.
10. A method of making a milling cutter for a key extending laterally in a lock bore, comprising: the method comprises the following steps:
the method comprises the following steps: firstly, a transmission shaft (2) is fixed on an output shaft of a motor, and an upper shell fixing plate (11) passing through a transmission shell (1) is fixed on a shell of the motor;
step two: when a vertical milling cutter (20) is needed to be used for vertically processing a key, the transmission shaft braking piece (9) is upwards slid through the rotating handle (903) on the transmission shaft braking piece (9), when the rotating handle (903) is dragged into the supporting groove (102), the worm (201) on the transmission shaft (2) is separated from the worm gear transmission rod (4), and the key can be processed through the vertical milling cutter (20);
step three: when a key needs to be transversely machined, the limiting assembly (10) is dragged downwards through a rotating handle (903) on the transmission shaft braking piece (9), so that the worm (201) is meshed and connected with the worm gear transmission rod (4), the worm (201) drives the worm gear transmission rod (4) to rotate, and then transverse craftsman can be conducted on the key through the transverse milling cutter (8);
step four: when the transverse milling cutter (8) needs to be transversely extended, the fastening nut (6) on the extension connecting piece (5) is rotated, the milling cutter connecting piece (7) is moved when the fastening nut (6) is separated from the second external thread (702), and the fastening nut (6) is screwed with the second external thread (702) after the fastening nut (6) is extended to a certain position.
