After adjusting to the appropriate position, the third adjusting screw 9 is rotated to lock the support cross bar 12 and the sliding seat 10. The structure is simple and realizes the rapid adjustment of the position of the sliding seat 10 on the support cross bar 12, thereby improving the practicality of the device.

[0022] like Figure 1 、 4 As shown, when in use, one side of the mounting cover body 5 is open, and a plurality of folding plates 11 are arranged inside the mounting cover body 5 from top to bottom. The two ends of the folding plates 11 are staggered in sequence from top to bottom, and the folding plates 11 located inside the mounting cover body 5 are rotatably connected to the inner wall of the mounting cover body 5. The folding plates 11 located inside the mounting cover body 5 are fixedly connected with guide rods 7 on both sides, and an arc groove 6 for accommodating the guide rod 7 is provided on the side wall of the mounting cover body 5. When the folding plates 11 rotate in the mounting cover body 5, the guide rod 7 can be driven to slide in the arc groove 6, thereby ensuring that the folding plates 11 are stably rotated and adjusted. The folding plates 11 with adjustable placement angles can meet the adjustment requirements during processing. Compared with the traditional fixed structure, it is beneficial for the staff to make real-time adjustments according to the processing requirements, thereby improving the quality of the mask folding processing.

[0023] like Figure 1、 4 As shown, in order to achieve stable rotation of the folding plate 11, openings 18 are opened on the ends of the folding plate 11, and a sleeve 14 is rotatably set inside the opening 18; a second adjusting screw 8 extending downward is threadedly connected to the mounting cover 5, and the bottom of the second adjusting screw 8 is rotatably connected to the top of the sleeve 14, and the top of the sleeve 14 is fixedly connected with a rotating seat 17, and the bottom of the second adjusting screw 8 is connected to the rotating seat 17.
