A cutting method of a laser cutting machine according to any one of claims 1 to 9, characterized in that: sleeving a workpiece on an inserting cylinder (3), starting a second motor (21), driving a first screw rod (20) to rotate by an output shaft of the second motor (21), enabling an adjusting block (19) to move downwards along an adjusting groove (18) under the action of threads, enabling the adjusting block (19) to synchronously drive a top plate (22) and a laser tool bit (23) to move downwards to the workpiece, then starting the laser tool bit (23) and a first motor (15) to cut, driving a second gear (16) to rotate by an output shaft of the first motor (15), driving a first gear (13) by meshing of the second gear (16), integrally rotating an inner shaft (12) and an arc-shaped plate (29), enabling the arc-shaped plate (29) to generate thrust on the top block (28), enabling the top block (28) to follow a sliding block (26) together, outwards move along a sliding groove (25), supporting the workpiece, fixing the workpiece, then enabling the workpiece to rotate together with the inserting cylinder (3), finishing cutting, meanwhile, when the workpiece rotates, scraping the scraping blade (9) scrapes burrs formed at the edges, scraping the burrs are scraped, and the burrs are collected by a splayed material collecting rod (9) connected with a first inner rod (7) and a rear scraping rod (9), the scraping plates (9) can be attached to the outer wall of the workpiece tightly, the deburring effect is improved, meanwhile, the two end parts of the scraping plates (9) form a splayed shape, when the workpiece is inserted into the inserting cylinder (3), the workpiece can be pressed down along the inclined surfaces of the scraping plates (9) and then directly sleeved on the inserting cylinder (3); the pressing plate (36) is arranged, when the top plate (22) moves downwards, the cross rod (35) and the rack (34) are synchronously driven to move downwards, the rack (34) is meshed to drive the third gear (33) to rotate, the third gear (33) synchronously drives the second screw (32) to rotate, the moving plate (31) moves inwards along the groove plate (30) under the thread fit, then the pressing plate (36) is synchronously driven to move inwards until the pressing plate (36) abuts against the other side of the workpiece to fix the workpiece, the third spring (38) is arranged, when the workpieces with different lengths are fixed, the pressing plate (36) firstly contacts the side face of the workpiece, then the top plate (22) continues to move downwards, the moving plate (31) continues to move inwards, namely the third spring (38) is compressed until the top plate (22) moves to a set position, and then the workpieces with different lengths can be fixed; furthermore, be provided with locating piece (40), when the work piece overlaps and inserts a section of thick bamboo (3) on, the work piece with insert a section of thick bamboo (3) and be in non-coaxial state, when pressure disk (36) move to the inboard, two locating pieces (40) earlier with the work piece contact, because the relative one side of two locating pieces (40) is the cambered surface, can adjust the work piece position through the cambered surface of two locating pieces (40), make the work piece coaxial with inserting a section of thick bamboo (3), then start first motor (15), drive the work piece and rotate.
