Meanwhile, in the process that the pressing handle 19 is pressed down, the vertical shaft 16 slides downwards to enable the second gear 15 to rotate under the transmission guide of the cam groove 17 and the cam push rod 18, and then the first gear 14 is driven to rotate reversely, and the one-way bearing 13 is in a transmission separation state in the rotating direction, so that the rotation of the first gear 14 cannot influence the nut 12.

After one end of the adsorbed hemostatic membrane 39 is moved to the outside of the case 1 through the discharge hole 38, the hemostatic membrane 39 is removed from the suction cup 10 without contacting other hemostatic membranes 39, and then the pressing handle 19 and the pushing handle 32 are sequentially released to reset the present invention.

When the pressing handle 19 is released, the pressing handle 19 is rapidly reset upwards under the elastic force of the first spring 20, the second spring 21 and the fourth spring 35, and simultaneously drives the push rod 6, the vertical shaft 16, the rack 27 and the guide rod 34 to perform upward reset sliding; when the push rod 6 slides upwards, the first piston 4 is driven to slide upwards in the cylinder 3, meanwhile, the second piston 5 slides upwards under the action of the tension spring 8, at the moment, the distance between the first piston 4 and the second piston 5 is kept unchanged, when the second piston 5 slides to be in contact with the upper end face of the limiting sliding groove 7, the second piston 5 stops sliding, the first piston 4 continues to slide upwards along with the push rod 6, the distance between the first piston 4 and the second piston 5 is reduced, and a part of air in the cylinder 3 is discharged; when the rack 27 slides upwards, the third gear 26 generates meshing rotation and drives the suction cup 10 to perform reset rotation, when the suction cup 10 rotates until the opening of the suction cup faces to the right lower side, the meshing of the rack 27 and the third gear 26 is finished, the suction cup 10 stops at the current position, at the moment, the push handle 32 can be loosened to enable the supporting plate 28 to slide upwards in a reset manner under the elastic force action of the third spring 29, and the uppermost hemostatic membrane 39 is close to the opening of the suction cup 10; when the vertical shaft 16 slides upwards, the second gear 15 rotates reversely under the transmission guiding action of the cam groove 17 and the cam push rod 18 and drives the first gear 14 to rotate forwards, the one-way bearing 13 is in a transmission joint state in the rotating direction, so that the first gear 14 drives the nut 12 to rotate simultaneously through the one-way bearing 13, the threaded rod 11 is lifted through thread transmission by the rotation of the nut 12, the tray 2 slides upwards under the driving of the threaded rod 11 to realize feeding operation, after the pressing handle 19 is completely reset, the vertical shaft 16 stops sliding, and the displacement generated by the thread transmission of the threaded rod 11, namely the feeding distance is equal to the thickness of the single hemostatic membrane 39, so that the uppermost hemostatic membrane 39 is in contact with the opening of the sucker 10 after the tray 2 is lifted, and the next taking-out operation is convenient; meanwhile, due to the self-locking effect of the thread transmission, when the nut 12 does not rotate, the screw 11 does not generate vertical displacement, so that the tray 2 is reliably stopped at the current position.

According to the above operation, when the hemostatic membrane 39 is completely taken out, the tray 2 is lifted to the upper side to be close to the suction cup 10, so that the tray 2 should be subjected to the position resetting operation before a new hemostatic membrane 39 is loaded, and the operation steps are as follows: the clamping block 36 is slid towards the axial direction of the nut 12, so that one end of the clamping block 36, which is far away from the axial line of the nut 12, is separated from the one-way bearing 13, at the moment, the nut 12 and the inner ring of the one-way bearing 13 can generate relative rotation, and the threaded rod 11, namely the lifting adjustment of the tray 2 can be realized by rotating the nut 12; after the tray 2 is reset, the fixture block 36 is loosened, the fixture block 36 is reset under the elastic force of the fifth spring 37, one end of the fixture block 36, which is far away from the axis of the nut 12, enters the inner ring of the one-way bearing 13, and the nut 12 and the inner ring of the one-way bearing 13 rotate simultaneously through the connection of the fixture block 36, so as to perform subsequent automatic feeding operation.

After the hemostatic membrane 39 is used, the discharge hole 38 is sealed by a dustproof cover and other devices in time so as to prevent pollutants in the external environment from invading the internal environment of the box body 1 and influencing the storage effect of the hemostatic membrane 39.
