There is a horizontal return spring between the slider and the baffle. There is a horizontal hole on the side wall of the slider close to the lower template. There is a rotating shaft in the horizontal hole, and the rotating shaft is in rotational fit with the horizontal hole. One end of the rotating shaft close to the lower template extends outside the slider. The outer extension end of the rotating shaft faces the open end of the positioning groove, and a rotating chuck is fixed on the outer extension end of the rotating shaft. There is a vertically arranged guiding hole on the slider on one side of the horizontal hole. The guiding hole is communicated with the horizontal hole. A gear is fixed on the corresponding section of the rotating shaft in the guiding hole. There is a rack in the guiding hole. The rack is meshed with the gear. The upper end of the rack is located above the slider, and a pressing block is fixed on the top of the rack. There is a vertically arranged limiting rod at the bottom of the pressing block.
