[0023] The working principle of this embodiment is as follows: when the blade assembly 22 is replaced, the milling mechanism 2 is moved to the top by the translation device 102, and then the blade assembly 22 is placed in the placement tube 105, and then the push rod 106 is started to release the direct connection between the blade assembly 22 and the milling mechanism 2 and fix it in the placement tube 105, and then the milling mechanism 2 is moved backward a certain distance, and the rotating disk 104 is rotated to align the blade assembly 22 to be replaced with the milling mechanism 2, and the milling mechanism 2 is moved forward, and the push rod is retracted, so that the placement tube 105 releases the fixation of the blade assembly 22 and establishes a connection between the blade assembly 22 and the milling mechanism 2.

[0024] Example 2: Based on Example 1, please refer to Figure 7-Figure 8The pressure assembly 21 includes a push rod 211, the inner wall of the shell 203 is fixedly connected to the push rod 211, the end of the push rod 211 away from the shell 203 is fixedly connected to the annular plate 212, the inner wall of the annular plate 212 is movably connected to the sliding column 213, the outer wall of the sliding column 213 is sleeved with a spring 214, the top of the spring 214 is fixedly connected to the sliding column 213, the bottom of the spring 214 is fixedly connected to the annular plate 212, the sliding column 213 penetrates the shell 203 and extends to the outside of the shell 203, the outer wall of the sliding column 213 is movably connected to the shell 203, the bottom of the sliding column 213 is fixedly connected to a movable ring 215, the movable ring 215, the side of the movable ring 215 away from the sliding column 213 is rotatably connected to a rotating ring 216 through a bearing, and the rotating ring 216 is away from the movable ring 215.

When the connection between the blade assembly 22 and the milling mechanism 2 is released, the push rod 106 will be embedded in the circular hole 3 227 and push the fixed column 231 to move. The moving fixed column 231 will drive the locking column 237 to be pulled out of the through hole 208 through the circular plate 232 and the connecting plate 234, thereby releasing the connection between the blade assembly 22 and the milling mechanism 2.

[0028] The working principle of this embodiment is as follows: when establishing a connection between the blade assembly 22 and the connecting head 207, first extend the connecting head 207 into the placement frame 224, then start the push rod 106 to shrink it, at which time the outer side of the fixed column 231 loses the support of the push rod 106, and then moves outward under the action of the spring 233, and the fixed column 231 moving outward drives the locking column 237 to move toward the placement frame 224 through the circular plate 232 and the connecting plate 234, and then allows the locking column 237 to pass through the circular hole 226 and embed into the through hole 208, so that the blade assembly 22 is connected to the milling mechanism 2.
