When the milling machine is working, the workpiece can be mounted on a workbench or accessories such as a dividing head. The rotary motion of the milling cutter is the main motion, supplemented by the feed motion of the workbench or milling head, so that the workpiece can obtain the desired processing surface. Milling machines are suitable for processing metal materials and have high efficiency, so they are widely used in machinery manufacturing and repair departments.

[0003] The tool holder of the existing CNC milling machines on the market is fixed to the output shaft by bolts, but the long-term operation of the tool holder will cause the overall internal structure to wear, so the internal wear will cause the fixed cutter head to shake, so when replacing the tool holder, a wrench must be used to tighten the bolts. It is not convenient to disassemble the tool holder by tightening the bolts with a wrench, so there is an urgent need for a CNC milling machine to quickly change the tool holder to solve the above problems.

[0020] As the first embodiment of the utility model: a group of stabilizing rods 305 are inserted into the bottom of the card plate 303, and the left side of the spring 306 is against the right side of the card plate 303. This design facilitates the spring 306 to push the card plate 303 to move. The two walls of the groove 301 are provided with positioning grooves, and the interior of the positioning groove is connected to the outside of the limit block 304. This design can increase the stability of the card plate 303 moving inside the groove 301. A slot is provided on the right side of the tool holder 2, and the interior of the slot is connected to the plug plate 307. This design facilitates the connection and fixation of the tool holder 2 and the connecting head 3.
