2Dial pointer type dial division value:The impact energy1/220；
The pointer has an active needle and a passive needle; The dial is divided into fixed dial and rotatable digital dial. The outer layer of the dial is the angle, the middle layer is the simply supported beam scale, and the inner layer is the cantilever beam scale.
3The jaw adopts a wedge-shaped self clamping jaw, which can clamp freely and is a newly developed product.
