The outer wall of the second sliding rod (14) is connected to the inner wall of the first support rod (5). One end of the second sliding rod (14) passes through the first support rod (5).

6. A forming method for an automatic folding and forming device of a packaging box according to claim 5, characterized in that, It includes the following steps: S1. Place the cut cardboard on the placing plate (15), and then control the first motor (3) to start through the control console (2); S2. The first motor (3) drives the threaded rod (4) to rotate. The threaded rod (4) drives the first support rod (5) to move. The first support rod (5) drives the first fixing plate (6) to move. The first fixing plate (6) drives the pressing plate (7) to move. The pressing plate (7) and the placing plate (15) cooperate to press the cardboard. S3. Control the second motor (20) to start through the console (2). The second motor (20) drives the first rotating rod (21) to rotate. The first rotating rod (21) drives the first gear (22) to rotate. The first gear (22) drives the rack (23) to move. The rack (23) drives the stopper (25) to move. The third sliding rod (24) limits the movement of the rack (23). The rack (23) simultaneously drives the connecting rod (26) to move. The connecting rod (26) drives the ejector rod (27) to move. The stopper (25) and the ejector rod (27) simultaneously drive the first clamping plate (16) and the second clamping plate (17) to move; S4. The first gear (22) drives the second gear (28) to rotate. The second gear (28) drives the second rotating rod (29) to rotate. The second rotating rod (29) drives the wire winding wheel (30) to rotate. The wire winding wheel (30) drives the pull rope (31) to move. The limiting plate (32) limits the movement of the pull rope (31). The pull rope (31) drives the third clamping plate (18) and the fourth clamping plate (19) to flip synchronously; S5. Then control the first motor (3) and the second motor (20) to reverse to take out the folded packaging box.

7. The forming method of an automatic folding and forming device for a packaging box according to claim 6, characterized in that: One rotation of the first gear (22) drives the second gear (28) to rotate five times. The first fixing plate (6) and the pressing plate (7) are limited by the clamping block (8).
