The working principle is as follows: when paper needs to be punched, firstly, the paper is placed on a workbench 101 fixedly arranged at the top end of a lower template 1, the position of the paper needing to be punched is aligned with a through hole 102 formed at the top end of the workbench 101, a cylinder 801 fixedly arranged in the middle of the top end of a starting top plate 8 is arranged, the cylinder 801 drives a telescopic rod 802 arranged at the bottom end in a sliding manner to move downwards, the bottom end of the telescopic rod 802 is fixedly connected with the middle of the top end of an upper template 104 and further moves through the telescopic rod 802, so that the upper template 104 can be driven to move along a guide post 103, meanwhile, mounting blocks 2 are fixedly arranged at two sides of the bottom of the upper template 104, a first rotating rod 201 arranged at the bottom of each mounting block 2 in a rotating manner can rotate around the first rotating rod 201 by a connecting rod 202, a same second rotating rod 204 is rotatably arranged between the bottoms of the connecting rods 202, a flattening roller 205 is sleeved at the outer side of the second rotating rod 204, and the flattening roller 205 is in surface contact with the workbench 101, the upper template 104 moves downwards to drive the flattening roller 205 to roll on the workbench 101, the outer sides of two ends of the two first rotating rods 201 are sleeved with the return springs 203, one end of each return spring 203 is fixedly connected with the first rotating rod 201, the other end of each return spring 203 is fixedly connected with the connecting rod 202, the flattening roller 205 can press paper on the workbench 101 through the return springs 203 to flatten the paper, the problems that when the paper is punched, the surface of the paper is wrinkled and the paper is not completely flattened, the punching precision of a punching die on the paper is influenced when the paper is punched are solved, meanwhile, when the upper template 104 continuously moves downwards, the sliding block 207 in the sliding groove 206 on the connecting rod 202 is also driven to move, so that the sliding block 207 drives the fixing rod 208 to enter the clamping groove 401, and the first clamping block 209 fixedly arranged at the top end of the fixing rod 208 is clamped with the second clamping block 403, therefore, the connecting rod 202 can be fixed, so that the situation that when the upper die plate 104 is lifted and the flattening roller 205 is returned is avoided, paper is driven to move, so that the paper is displaced, and the paper punching is influenced, meanwhile, the matching rods 105 fixedly arranged on the two sides of the bottom of the upper die plate 104 drive the matching rods 105 to move when the upper die plate 104 moves downwards, so that the matching rods 105 compress the first piston rod 5, so that the first piston rod 5 is driven to compress air in the first piston chamber 503 through the first piston 502, so that the second piston 505 in the second piston chamber 504 can be driven to move upwards, so that the second piston 505 drives the second piston rod 507 to move, in addition, the first piston rod 5 and the second piston rod 507 can be reset through the first spring 501 and the second spring 506, so that the clamping block 601 rotatably arranged on the top of the mounting plate 6 is propped through the second piston rod 507, the paper can be clamped through the clamping block 601, the problem that when more paper is punched, the paper is easy to shift due to a certain thickness caused by more stacked paper when the paper is unevenly stressed, and the punched hole position is inclined, so that the punching is unqualified is avoided, and the problem that when the paper is flattened by the flattening roller 205, the paper is moved to cause the punching position error of the paper is also avoided, after the paper is punched, the cylinder 801 drives the telescopic rod 802 to move upwards to drive the upper template 104 to move upwards, when the paper is lifted to a certain position, the second movable rod 406 movably arranged in the middle of the fixed frame 405 fixedly arranged on one side of the top end of the upper template 104 is contacted with the bottom end of the top plate 8, so that the second movable rod 406 moves downwards, and the matching block 408 fixedly arranged at the bottom end of the second movable rod 406 pushes the first movable rod 402 to move towards two sides, thereby make the second fixture block 403 that first movable rod 402 other end was equipped with separate with first fixture block 209, fixed plate 3 and first reset spring 301 that are equipped with through cope match-plate pattern 104 bottom end fixation reset to flattening roller 205 simultaneously, the centre of cope match-plate pattern 104 bottom is fixed and is provided with mounting bracket 7, installation sleeve 701 and fixing bolt 702 through fixing being provided with in the middle of the mounting bracket 7 bottom, can carry out fixed mounting to perforating sword 703, opening 704 has
