[0031] Inside the box body 1, there is a horizontally arranged grille 3 for placing electrode plates. A placing flange 14 is convexly provided on the inner cavity side wall of the box body 1. The grille 3 is designed separately from the box body 1, and the grille 3 is placed on the placing flange 14. The opening size of the grille 3 is a square opening with a length and width of 20 - 60 mm each.

[0032] The box body 1 is provided with a pull-out drawer 4 for receiving the dropped lead paste in the area below the grille 3. One side of the pull-out drawer 4 exposed outside the box body 1 is provided with a handle 42. The handle 42 facilitates the operation of loading the pull-out drawer 4 into the box body 1 and pulling it out of the box body 1. One side of the pull-out drawer 4 exposed outside the box body 1 has a flange 43. When the pull-out drawer 4 is matched with the box body 1, the flange 43 abuts against the outer side surface of the box body 1, and a sealing ring 44 is provided on the abutting surface between the two. A buckle point 45 and a buckle 13 are respectively provided between the side of the pull-out drawer 4 exposed outside the box body 1 and the outer side surface of the box body 1. The buckle 13 is provided with a buckle hole for cooperating with the buckle point 45. As Figure 1 shown, one buckle point 45 is provided at each of the two side edges of the pull-out drawer 4. Correspondingly, one buckle 13 is provided on each of the two sides of the box body 1. After the end of the buckle 13 is bent, the buckle point 45 is snapped into the buckle hole of the buckle 13, so that a sealed fit is maintained between the pull-out drawer 4 and the box body 1.

[0033] The bottom surface of the box body 1 is provided with a first drain hole, and the bottom surface of the pull-out drawer 4 is correspondingly provided with a second drain hole. The first drain hole and the second drain hole are arranged opposite to each other.
