The V-shaped frame 13 includes two flip rods, and the two flip rods are fixedly connected to the rotating shaft 19. An angle that can receive the electrode paste 3 is formed between the two flip rods, and the lengths of the two flip rods are suitable enough to facilitate receiving the electrode paste 3.

[0040] The frame is rotatably connected to a large gear 15, a fourth gear is fixedly sleeved on the rotating shaft 19, the frame is fixedly connected to a guide sleeve 17, the guide sleeve 17 is slidably connected to a rack 16, the large gear 15 is respectively meshed with the fourth gear and the rack 16, when the rack 16 slides, it can drive the large gear 15 to rotate, and the large gear 15 can drive the rotating shaft 19 to rotate through the fourth gear.
