Welding plate in oscillating bar mechanism of drop-out fuse

The invention discloses a welding plate in an oscillating bar mechanism of a drop-out fuse. The welding plate is perpendicularly arranged, the outline of the surface of the welding plate is curved and is composed of six sections of arcs, the first section of arc is an upwards-protruding convex arc, the second section of arc is a leftwards-sunken concave arc, the third section of arc is a rightwards-protruding convex arc, the fourth section of arc is a downwards-sunken concave arc, the fifth section of arc is a leftwards-protruding convex arc, and the sixth section of arc is a rightwards-sunken concave arc; the first section of arc, the second section of arc, the third section of arc, the fourth section of arc, the fifth section of arc and the sixth section of arc are sequentially connected end to end in the clockwise direction. The position, below the first section of arc, of the welding plate and the position, above the fourth section of arc, of the welding plate are each provided with an assembly hole, and the two assembly holes are arranged in an eccentric mode. By means of the welding plate in the oscillating bar mechanism of the drop-out fuse, the amplitude of swing of the oscillating bar mechanism of the drop-out fuse can be controlled more accurately.
