1: the pushing block 15 is pulled manually to drive the pushing rod 16 to move leftwards, so that the distance that the moving plate 24 can move leftwards is determined, so that the cut-off distance is determined, the driving motor 39 is operated to drive the driving shaft 14 to rotate, so that the friction block 66 is driven to move backwards, so that the connecting block 69 and the lower pressing plate 11 are driven to move backwards, so that the lower pressing plate 11 is separated from the upper side of the lower pressing rod 13, at this time, the lifting spring 52 is reset, so that the thread block 53 is driven to move upwards, so that the thread block 53 and the driving shaft 14 are in threaded fit, during the process that the driving shaft 14 rotates to drive the pushing rod 16, the first bevel gear 42 and the second belt pulley 41 rotate along with the rotation of the driving shaft 14, the rotation of the first bevel gear 42 drives the second bevel gear 64 to rotate, so that the lifting shaft 60 is driven to rotate, so that the threaded rod 61 is, thereby driving the supporting block 32 and the rotating shaft 33 to move upwards;

2: when the driving shaft 14 is engaged with the screw block 53, the driving shaft 14 continues to rotate, so that the screw block 53 is driven to move leftward, so that the moving plate 24 is driven to move leftward, at this time, the electromagnet 49 operates to repel the magnet block 50, so that the magnet block 50 is away from the electromagnet 49, so that the clamping rod 18 is away from the moving plate 24, as the moving plate 24 moves leftward, the ejecting spring 23 is reset to drive the ejecting block 21 to move leftward, so that the chain 74 is loosened and the rope 46 is tensioned, the chain 74 is loosened, so that the connecting spring 67 is reset, so that the connecting block 69, the sliding groove 70 and the sliding block 73 move upward, the rope 46 is tensioned, so that the moving plate 82 moves leftward, so that the spring block 58 and the threaded rod 61 are driven to move leftward, so that the threaded rod 61 is disengaged from the lifting shaft 60 and the right end of the threaded rod 61 is separated from the through hole 62, the extension, thereby moving the supporting block 32 and the rotating shaft 33 upward to the uppermost side, thereby moving the elevating block 34 upward to the uppermost side, and when the threaded rod 61 is removed from the threaded rod 61, the compression spring 57 is restored, thereby moving the spring block 58 and the threaded rod 61 upward;

3: when the moving plate 24 moves leftwards to contact with the contact sensor 80, the electromagnet 49 is operated to attract the magnet block 50, so that the magnet block 50 approaches towards the electromagnet 49, so that the clamping rod 18 approaches towards the moving plate 24, so that the clamping rod 18 clamps the bamboo tube, and when the moving plate 24 contacts with the contact sensor 80, the driving motor 39 is operated to reverse the driving shaft 14, so that the friction block 66 moves forwards, so that the connecting block 69 and the lower pressing plate 11 are reset, and when the driving shaft 14 reverses to move rightwards to drive the moving plate 24, so that the magnet block 50 and the clamping rod 18 move rightwards, so that the bamboo tube moves rightwards, and when the moving plate 24 moves rightwards to drive the ejecting block 21 to reset, the ejector spring 23 is recompressed, the chain 74 is tightened and the cord 46 is released, and at the same time, the lower link 13 moves to the right along with the screw block 53, the right end of the lower link 13 is again positioned at the lower side of the lower press plate 11, as the chain 74 is tightened, the sliding block 73 and the sliding groove 70 are lowered, and the connecting block 69 is lowered, so that the connecting spring 67 is stretched again, the descending of the lower pressing plate 11 drives the lower pressing rod 13 to descend, thereby lowering the threaded block 53 and disengaging the threaded block 53 from the drive shaft 14, and the cord 46 is released, resetting the extension spring 48, moving plate 82, and thus spring block 58 and threaded rod 61, to the right, so that the right end of the threaded rod 61 passes through the through-hole 62 and is re-threadedly engaged with the elevation shaft 60, when the threaded block 53 is disengaged from the drive shaft 14, the right end of the threaded rod 61 just re-engages with the lifting shaft 60;

4: at this time, the reverse rotation of the driving shaft 14 drives the first bevel gear 42 and the second pulley 41 to rotate reversely, the reverse rotation of the first bevel gear 42 drives the second bevel gear 64 to rotate reversely, so that the lifting shaft 60 rotates reversely, so that the threaded rod 61 moves downwards, so that the lifting block 34 moves downwards, so that the rotating shaft 33 moves downwards, so that the cutting wheel 28, the first pulley 31 and the supporting block 32 are driven to descend, the descending of the first pulley 31 gradually starts to tension the belt 35, the descending of the supporting block 32 causes the supporting spring 29 to be tensioned again, when the belt 35 contacts with the blocking wheel 36 in the gradual tensioning process, the second pulley 41 and the first pulley 31 realize transmission, and the rotation of the second pulley 41 drives the first pulley 31 to rotate, so that the rotating shaft 33 is driven to rotate the cutting wheel 28, and as the lifting block 34 continues to descend, so that the cutting wheel 28 continues to descend, cutting is initiated when the cutting wheel 28 comes into contact with the bamboo tube, and when the cutting wheel 28 descends to the lowermost side, it indicates that the bamboo tube is cut completely within the cutting chamber 25.
