<p>A nail-clamping plastic bar on a nail gun, which consists of two or more clamping units connected in series; each clamping unit comprises: at least two clamping rods and as many connecting strips as the clamping rods; each connecting strip is used to connect two adjacent clamping rods together; the two connected together form a ring body capable of being sleeved on the nail rod; and two adjacent clamping units are connected together through one or more connecting ribs. The plastic bar is designed to be formed by multiple clamping units connected in series, and can be bent to fit nail casing of different shapes. The chamfers at the two ends of each clamping rod, the outer wall, and the inner wall of the clamping rod can be respectively molded in half in the front and rear dies; the connecting strips can also be molded in half in the front and rear dies without any sliding block, so the die space can be fully utilized, and the die of the same volume can generate more bar-shaped cavities. Therefore, the die efficiency is greatly improved and the die cost is reduced. ] Fig. 1 Fig. 2 Fig. 3</p> |
