In the use process, the cut workpiece is pressed against the lower surface of the first protective sleeve 5c, the first protective sleeve 5c overcomes the elasticity of the second elastic piece 6c and moves upwards, at the moment, the third blade 3c is exposed from the opening 51c to cut the workpiece, and in the non-use state, the first protective sleeve 5c moves downwards under the action of the second elastic piece 6c to hide the third blade 3c therein, so that the protection function is realized, the third blade 3c is protected, and the accidental injury of workers is prevented. The outer peripheral wall of the first protecting sleeve 5c is provided with a first step 52c, the outer peripheral wall of the lower part of the third sleeve 1c is correspondingly provided with a second step 15c, the second elastic piece 6c is a spring sleeved on the outer periphery of the third sleeve 1c and the first protecting sleeve 5c, the first end of the spring is propped against the first step 52c, and the second end of the spring is propped against the second step 15.
When the cutter head with the fine adjustment function of the embodiment is used, in the running process of the machine, when the height of the third blade 3c is required to be adjusted, the whole machine does not need to stop running, only the cutting action of the cutter head is required to be suspended, the second adjusting rod 4c is rotated to finely adjust the height of the third blade 3c, the operation is simple, and the use is convenient.
