[0025] Embodiment 3

[0026] like Figure 2-Figure 5As shown, the utility model proposes an inclined arm type screen printer that is easy to adjust. Compared with the second embodiment, the present embodiment records the detailed structure of the angle adjustment assembly, which includes a fixed frame 8, a rotating plate 9, a limit plate 10 and a fixing bolt 12. The upper end surface of the fixed frame 8 is rotatably connected to the two threaded rods 6 through a bearing, the lower end surface of the fixed frame 8 is used for hingedly connecting the rotating plate 9, and the rotating plate 9 is used for connecting a scraper. The limit plate 10 is detachably connected to the fixed frame 8, and a limit groove 11 for limiting the angle of the rotating plate 9 is provided on the limit plate 10;

[0027] In an optional embodiment, the limiting plate 10 is composed of two movable plates 13, and dovetail blocks 14 arranged side by side are provided on the movable plates 13, and the dovetail blocks 14 are slidably connected with dovetail grooves 15 provided on the fixed frame 8; the movable plate 13 is U-shaped, and the movable plate 13 moves toward each other from both ends of the fixed frame 8 through the dovetail blocks 14 on the top thereof to limit the angle of the rotating plate 9;

[0028] The fixing bolt 12 passes through the through hole on the fixing frame 8 and is threadedly connected with the limiting plate 10 .

[0029] In an optional embodiment, a plurality of evenly distributed protrusions 16 are connected to the opposite ends of any one of the movable plates 13, and a groove 17 for slidingly connecting with the protrusion 16 is connected to the other limiting plate 10; the two U-shaped movable plates 13 can be more conveniently disassembled from two directions by combining the protrusion 16 and the groove 17 at the top, and also avoid the situation where the movable plate 13 is skewed during installation.
