the design of the fixed magnetic stripe 907 and the rotary magnetic stripe 908 is adopted, during buckling and clamping of the upper clamping plate 905 and the lower clamping plate 906, the fixed magnetic stripe 907 and the rotary magnetic stripe 908 can be deviated by rotating the rotary magnetic stripe 908, and further the attraction between the fixed magnetic stripe 907 and the rotary magnetic stripe 908 is adjusted, so that the fact that the upper clamping plate 905 and the lower clamping plate 906 have large magnetic force to fix in the process of clamping the fabric is ensured, the magnetic attraction is reduced in the opening process of the upper clamping plate 905 and the lower clamping plate 906, meanwhile, the part, which is suspended outside the upper clamping plate 905 after the rotary magnetic stripe 908 is rotated, can also serve as an acting point when the upper clamping plate 905 and the lower clamping plate 906 are pulled, and the use process of the rapid feeding mechanism 9 is further optimized;

after the connecting ring 903 passes through the cutting box 2 and reaches the tail end of the other end of the machine tool base 1, the connecting ring 903 is taken down from the outer side of the limit nail 902, then the connecting ring 903 is inserted into the connecting groove 914 on the outer side of the collecting roller 913, the connecting ring 903 is fixed to the outer side of the collecting roller 913 through the friction force between the outer side of the connecting ring 903 and the inner wall of the connecting groove 914, the collecting roller 913 is driven to rotate through the action of the rotating motor 911 and the magnetic connector 912, and therefore the cutting residual waste materials are wound up through the collecting roller 913, the waste materials are directly separated from the cut surface material pieces after leaving the conveying belt 4, and the collecting process of the cutting residual waste materials;

after the fabric moves to a target position under the combined action of the conveying belt 4 and the collecting roller 913, the rotation of the conveying belt 4 and the collecting roller 913 is stopped at the same time, then the fabric is paved, the driving motor 802 is started to drive the bidirectional screw 803 to rotate in the forward direction, further the driving block 815 is driven to slide along the outer side of the bidirectional screw 803 to two ends, in the process of initial movement of the driving block 815, under the combined action of the volute spiral spring 806, the driving barrel 807 and the driving ring 808, a traction force pointing to the midpoint of the bidirectional screw 803 is applied to one side of the transverse installation box 801 through the limiting rope 809, after the driving inclined block 816 is contacted with the driven inclined block 814, the driving inclined block 816 applies a thrust force pointing to two ends of the bidirectional screw 803 to the driven inclined block 814, at the moment, the sliding box 810 is subjected to the same direction of the friction force and the combined action of the traction force, the thrust force and the friction force between the sliding box, in the process that the driving inclined block 816 and the driven inclined block 814 approach gradually, the driven inclined block 814 drives the lifting block 812 to slide downwards under the action of vertical component force to overcome the elastic force of the return spring 813, so that the lifting block 812 drives the movable cross bar 817 and the scraper 818 to move downwards and contact with the fabric on the top of the conveying belt 4;
