9. The anti-dumping vegetable transplanting pit digging device according to claim 8, characterized in that: A hand wheel (28) is coaxially fixedly mounted on the top end of the second screw rod (26).

10. A method for using a vegetable transplanting pit digging device that prevents tipping, characterized in that: The following steps are involved: Step 1: Hold the handheld frame (29) and move the device to a suitable position through the universal wheels, then turn the operating handles (11) on both sides to rotate the threaded rod (10), and under the action of the threaded connection between the threaded rod (10) and the fixing plate (9), the threaded rod (10) is rotated and moved downward, so that the threaded rod (10) is inserted into the soil to improve stability and prevent tipping; Step 2: Start the motor (12) to rotate the first screw rod (13), so that the lifting plate (2) threadedly connected to the first screw rod (13) moves downward, thereby driving the slide plate (4) and the pit-digging drill rod (5) to move downward synchronously; Step 3: When the first screw rod (13) rotates, the transmission rod (14) is driven to rotate through the first bevel gear set (15), so that the rotating rod (19) is driven to rotate through the second bevel gear set (18), and the rotating rod (19) drives the linkage rod (20) to rotate synchronously, and the digging drill rod (5) is driven to rotate synchronously under the action of the linkage rod (20) and the connecting groove (21), so as to ensure that the digging drill rod (5) moves downward while rotating, so that the digging drill rod (5) extends into the soil to realize digging; Step 4: The second screw rod (26) is rotated by turning the hand wheel (28), so that the connecting block (27) threadedly connected to the second screw rod (26) drives the movable plate (22) to move up and down. In the process of the guide groove (23) moving with the movable plate (22), the slide rod (24) drives the connecting rod (25) and the slide seat (8) to move horizontally through the cooperation between the guide groove (23) and the slide rod (24). The movement of the slide seat (8) drives the rotating rod (19) to move synchronously, so that the angle plate (17) drives the hollow tube (16) and the second bevel gear set (18) to move horizontally on the surface of the transmission rod (14). At the same time, the rotating rod (19) drives the linkage rod (20) to move horizontally synchronously, so that the linkage rod (20) drives the pit-digging drill rod (5) to move horizontally under the action of the slide plate (4), so as to adjust the spacing of the pit-digging drill rod (5).
