8. A stamping apparatus as defined in claim 1, wherein: the outer side wall of the second threaded cylinder (34) is rotatably connected with a second limiting ring (39), and the second limiting ring (39) is fixedly connected with the connecting lug (31).

9. A stamping apparatus as defined in claim 1, wherein: the inside wall fixedly connected with of rotary rod (333) is spacing post (334), spacing groove (335) have been seted up to the lateral wall of lifter plate (38), the one end of spacing post (334) with the inside wall sliding connection of spacing groove (335).

10. A method for using a punching apparatus convenient for positioning, which is characterized in that the punching apparatus convenient for positioning according to any one of the items 1 to 9 is used, and the method comprises the steps of:

when the stamping device is used, equipment needing stamping is placed on the top surface of a second connecting plate (23), a pushing plate (332) is pushed inwards on clamping mechanisms (3) on two sides, the pushing plate (332) slides inwards on a rotating seat (331), the pushing plate (332) drives an inner adjusting rod (325) to slide inwards, and therefore limiting rods (326) at two ends of the adjusting rod (325) move on a sliding rail (324), two clamping plates (321) rotate inwards, and the two clamping plates (321) fix the stamping plates;

secondly, rotating a knob (244) to adjust the rotating distance of a first screw rod (243) on a first threaded cylinder (242), so that the first screw rod (243) drives a positioning plate (245) to slide on the top surface of a second connecting plate (23), the sliding distance of a fixed plate (241) on the top surface of the second connecting plate (23) is adjusted, a second air cylinder (251) is started, the second air cylinder (251) drives a sliding plate (252) to move towards the fixed plate (241), and the sliding plate (252) and the fixed plate (241) clamp a middle stamped plate;

step three, when the second cylinder (251) drives the sliding plate (252) to move, the sliding plate (252) drives the toothed plates (37) on two sides to move through the sliding angular plate (253), so that the toothed plates (37) drive the gear (36) to rotate, the gear (36) drives the second threaded cylinder (34) to rotate on the second limiting ring (39), the second screw (35) moves downwards in the second threaded cylinder (34) through the threaded connection of the second threaded cylinder (34), so that the stamping plate clamped between the clamping components (32) is driven to be in contact with the second connecting plate (23), the first cylinder (15) is started, and the first cylinder (15) drives the stamping die (16) to stamp one surface of the stamping plate;

fourthly, the first air cylinder (15) is started to drive the stamping die (16) to reset to the top end, the second air cylinder (251) is started to drive the sliding plate (252) and the stamping plate not to limit any more, meanwhile, the sliding plate (252) moves outwards to drive the toothed plate (37) to slide outwards, so that the toothed plate (37) drives the second threaded cylinder (34) to rotate reversely, the second screw (35) moves upwards through the second threaded cylinder (34), the stamping plate clamped by the clamping assembly (32) is lifted upwards, the rotating rod (333) rotates one hundred eighty degrees on the track of the limiting groove (335), the rotating rod (333) drives the pushing plate (332) to turn over for a half circle, and the reverse side of the stamping plate is turned over;

and step five, the second air cylinder (251) is started again, the second air cylinder (251) drives the sliding plate (252) to clamp the clamping plate, meanwhile, the overturned stamping plate drives the second screw (35) to move downwards through the toothed plate (37), the other side of the stamping plate is in contact with the positioning mechanism (2), and the stamping positioning of the reverse side of the stamping plate is realized.
