The adjustability is strong, and it is suitable for adaptive clamping and anti-arc-off treatment on the surface of circuit bodies 5 of various sizes.

The positioning screw sleeve 7 can be fixed by the direct threaded connection between the positioning screw sleeve 7 and the terminal 3. During installation, the positioning screw sleeve 7 is inserted along the bottom end of the terminal 3 and fixed on the outer surface of the terminal 3 by gradually rotating. After the anti-arcing plate 9 is adjusted to the inner wall of the anti-slip nut abutting against the surface of the circuit body 5, the anti-slip nut is inserted upward along the bottom surface of the circuit body 5 and connected.
