step S3: after the new cutting head main body (14) rotates, the clamping block (17) can be clamped into the fixed guide seat (18) and is abutted against the inner wall of the wedge-shaped guide groove (19), the clamping block (17) is pushed to move downwards by the pressure of the wedge-shaped guide groove (19), and the clamping block (17) drives the sliding column (13) to move downwards and pushes the new cutting head main body (14) to pop out downwards;
step S4: then, arranging the materials to be cut on a lower supporting base (7), driving a lifting platform (5) to move by using a power transmission mechanism (3), and synchronously driving a cutting cylindrical base (6) and a cutting head main body (14) to move so as to cut the materials to be cut;
step S5: the power transmission mechanism (3) provides power by using a power transmission motor body (22), the power transmission motor body (22) drives a driving wheel (23) to rotate after rotating, the driving wheel (23) drives a belt (2301) to rotate, the belt (2301) drives a driven wheel (25) to rotate, the driven wheel (25) drives a first gear (26) to rotate, the first gear (26) drives a second gear (27) to rotate, the second gear (27) drives a third gear (28) to rotate, the third gear (28) drives a fourth gear (29) to rotate, the fourth gear (29) drives an elliptical plate (30) to rotate, the elliptical plate (30) drives a rotation limiting shaft (31) to rotate, the rotation limiting shaft (31) drives a connecting rod (32) to move, the connecting rod (32) drives a transmission shaft (34) to move, and the transmission shaft (34) drives a standing plate (33) and a lifting platform (5) to move;
step S6: after the lifting platform (5) moves, the lifting platform (5) drives the limiting sleeve (501) and the limiting fixing column (4) to relatively slide, the circular motion is converted into linear reciprocating motion by the cooperation of the elliptical plate (30), the connecting rod (32) and the rotating limiting shaft (31), and the lifting platform (5) further drives the cutting cylindrical base (6) and the cutting head main body (14) to continuously reciprocate up and down to cut materials;
step S7: and when the cutting head main body (14) needs to be replaced subsequently to continue cutting, repeating the steps S1-S6.
