[0024] In this embodiment, when the hydraulic rod 71 drives the slitting knife 73 to move downward to slit the plastic film, it can drive the connecting plate 75 to move downward to clamp the end of the plastic film after slitting through the clamping plate 77. After slitting, the operator can hold and remove the fitted connecting plate 75 and clamping plate 77 and clamp the end of the plastic film to move it to the winding drum 5 for the next winding, thereby improving the convenience of slitting and winding the plastic film.

[0025] The upper end of the transverse plate 76 is provided with a slitting groove, the specification of which matches that of the slitting knife 73 , and the plastic film is slit by the slitting knife 73 that moves downward and extends into the slitting groove.

[0026] In addition, a placement groove is opened at the upper end of the horizontal plate 76, and the clamping plate 77 is placed on the inner side of the placement groove. The placement groove is concave in shape, and the clamping plate 77 can be placed in the placement groove.
