[0025] Specifically, the front end of the slide plate 2 is fixedly connected to a transverse tooth plate 8, and the outer side of the transverse tooth plate 8 is meshingly and rotatably connected to a stretching rod 9. Two groups of stretching rods 9 are provided, and the outer side of the stretching rods 9 is provided inside the packaging bag 11. The bottom end of the slide plate 2 is slidably provided on the top of the base plate 1, and the transverse tooth plate 8 slides to the left and slides with the outer stretching rod 9, so that the stretching rod 9 can be opened conveniently to facilitate the horizontal expansion of the packaging bag 11.

[0026] Furthermore, a square groove is opened inside the skateboard 2, and the bottom end of the handle 5 is arranged inside the square groove of the skateboard 2. The outer side of the handle 5 is tightly set against the skateboard 2. The handle 5 slides on the top of the skateboard 2 to facilitate sliding the horizontal tooth plate 8 on the left side of the skateboard 2.

[0027] Furthermore, a lifting rod 13 is fixedly connected to the top of the base 12, and the packaging bag 11 slides upward from the bottom. During the upward sliding process, the inner center position of the extension rod 16 is rotatably connected to the extension rod 17, and the torsion spring 20 sleeved on the outside of the extension rod 16 outside the lifting rod 13 rotates, and the packaging bag 11 slides out from the bottom end of the rotating wheel 19 at the bottom end of the rotating rod 18, and the tomatoes are bagged in sequence reciprocatingly.

[0028] It is worth mentioning that a rotating rod 18 is tightly arranged on the outer side of the torsion spring 20, a sliding groove is opened at the bottom end of the rotating rod 18, and a rotating wheel 19 is rotatably connected inside the sliding groove of the rotating rod 18, which facilitates the packaging bag 11 to be pressed tightly and assists sliding.
