[0028] Furthermore: the embedment block 1201 is clamped in the right side of the support plate 1101 through the embedding groove 1102, so that the cutter head body 1204 will not be misaligned between the fixed seat 1202 and the support plate 1101 after installation, thereby increasing the stability of the cutter head body 1204 after installation. There is a gap between the fixed seat 1202 and the support plate 1101 and they are not in direct contact with each other, so that the fixed seats 1202 of different thicknesses can be installed. Embodiment 2

[0029] See also Figure 2-4 On the basis of the first embodiment, it is further obtained that the fixing mechanism 2 includes a clamping component 21 and a fixing component 22, the clamping component 21 is arranged on the left side of the connecting component 12, and the fixing component 22 is arranged on the left side of the supporting component 11.

[0032] In the actual operation process, when the cutter head body 1204 needs to be installed, the staff first places the cutter head body 1204 on the right side of the support plate 1101, and then adjusts the position of the cutter head body 1204 through the fixing screw barrel 2102 and the card slot 2103, and then moves the cutter head body 1204 to the left. The cutter head body 1204 moves to the left and drives the fixing seat 1202 to move to the left through the connecting block 1203. The fixing seat 1202 moves to the left and drives the fixing screw barrel 2102 to move to the left through the second convex plate 2101. 2 moves to the left, the fixed screw barrel 2102 moves to the left and is engaged with the first convex plate 1103 through the slot 2103 until the left side of the embedded block 1201 fits with the embedded slot 1102. At this time, the staff will sleeve the bolt 2202 on the inner circle of the fixed sleeve 2201 and rotate it. The fixed sleeve 2201 rotates and contacts the fixed screw barrel 2102. The inner circle of the fixed screw barrel 2102 moves downward until the bolt 2202 is sleeved on the inner circle of the fixed sleeve 2201 on the other side. At this time, the installation of the cutter head body 1204 is completed.
