[0027] Working principle: in the initial state, the limiting clamp plate 2 slides on the base 1 and is also threadedly connected with the screw rod 31 rotating on the base 1. The first gear 32 meshing with the second gear 33 is fixed on one of the screw rods 31, and the other screw rod 31 is connected to the transmission shaft 34 fixed on the second gear 33 through a pulley set 35. The second gear 33 is consistent in size with the first gear 32. Therefore, after a single screw rod 31 rotates forward, the other screw rod 31 will rotate in the opposite direction, and the rotation speeds of the two screw rods 31 are consistent, so that the two limiting clamp plates 2 threadedly connected with the two screw rods 31 slide toward the center of the base 1 respectively, and the first bevel gear 36 fixed on the screw rod 31 is meshed with the second bevel gear 37, and the second bevel gear 37 is fixed on the rotating shaft 45. The rotating shaft 45 rotating on the base 1 is also fixed with a turntable 41, which is fixed on the turntable 41. The connecting seat 43 is provided with a connecting shaft 411, a cam 410 is fixed on the connecting shaft 411, and the extension rod 42 is fixed on the cam 410. The connecting shaft 411 is further connected to the connecting seat 43 by a return torsion spring 413. The ball head rod 44 located below the cam 410 slides inside the fixed rod 46. The ball head rod 44 is also further connected to the fixed rod 46 by an auxiliary spring 49. The sliding rod 48 sliding on the fixed rod 46 is fixed with a friction block 47 in contact with the base 1. The contact surface between the friction block 47 and the base 1 is provided with a plurality of fine grooves for enhancing friction, which are used for the connection between the friction block 47 and the base 1. Because the fixed rod 46 is fixed on the turntable 41, when the friction block 47 contacts the base 1, the turntable 41, the rotating shaft 45 and the second bevel gear 37 are in an immobile state, thereby locking the position of the limit clamp 2.

[0028] When the distance between the two limit clamps 2 needs to be adjusted for cutting and positioning paper bubble envelope bags of different sizes, the extension rod 42 is rotated so that the protrusion on the cam 410 squeezes the ball head rod 44, causing the ball head rod 44 to slide downward. Under the action of the connecting rod 412 movably connected to the sliding rod 48 and the ball head rod 44 at both ends, when the ball head rod 44 descends, it will pull the sliding rod 48 and the friction block 47 to slide toward the fixed rod 46, so that the friction block 47 does not contact the base 1. At this time, the extension rod 42 can be used to rotate the turntable 41, and the rotating shaft 45 rotates therewith. Under the transmission of the second bevel gear 37, the first bevel gear 36, the first gear 32, the screw rod 31, the transmission shaft 34 and the pulley group 35, The two screw rods 31 rotate in opposite directions, thereby causing the two limit clamps 2 to slide toward the center of the base 1 until the paper bubble envelope bag is clamped and positioned at the center of the base 1. After loosening the extension rod 42, under the action of the reset torsion spring 413, the extension rod 42 and the cam 410 rotate to the initial horizontal position. At this time, the cam 410 does not contact the ball head rod 44, and under the action of the auxiliary spring 49, the ball head rod 44 slides up to the initial position, and then the connecting rod 412 is used to push the friction block 47, so that the friction block 47 contacts the base 1. Through the friction between the two, the rotation of the entire structure is limited, and the position of the limit clamp 2 is locked. At this time, the paper bubble envelope bag between the two limit clamps 2 can be cut.
