When the driving member is started, the abutment member is driven to move in the positioning cylinder 105 toward the workbench 101, so that the positioning cylinder 105 can clamp and fix one end of the film, thereby cooperating with the pressure roller in the prior art to straighten and fix the two ends of the film, so as to facilitate cutting. In the process of cutting the film using the cutting knife, one end of the film is fixed by the pressure roller, and the other end of the film is placed under the abutment member. The driving member is started and drives the abutment member to move in the positioning cylinder 105 toward the workbench 101 until the abutment member abuts against the film, so that the abutment member and the pressure roller cooperate with each other to straighten and fix the two ends of the film, thereby avoiding the film from deflecting and affecting the cutting effect.
