The fixing module 2100 comprises a clamping tool 1000 and a first fixing base 2110, wherein a first through hole 1100 is formed in the clamping tool 1000, and the cross section of the first through hole is larger than that of one end of a material to be cut. A through groove 2111 is formed in the bottom of the first fixing base 2110, the clamping fixture 1000 is installed at the bottom of the first fixing base 2110, and a second through hole 2112 is formed between the top surface of the clamping fixture 1000 and the through groove 2111. The opening size of the through groove 2111 is larger than the size of the first through hole 1100, for example, when the first through hole 1100 is circular, the opening size of the through groove 2111 is larger than the diameter of the first through hole 1100; when the first through hole 1100 is rectangular, the opening size of the through groove 2111 is larger than the length of the side of the first through hole 1100 perpendicular to the radial direction of the through groove 2111. The cutting module is provided with a cutter 2210, and the cutter 2210 is in sliding fit with the second through hole 2112.
