Combined dart with polyhedral shaft

Abstract

A dart comprises a barrel 1 , a shaft 2 and a tip 3 that are arranged on the barrel 1, and a flight 4 arranged on the shaft 2. A body of the shaft 2 has a cross section shaped as a polygon. The polygon may be a triangle, a rectangle, a parallelogram, a trapezoid, a regular pentagon or a regular hexagon. The shaft 2 is provided with a reinforcing rod. The reinforcing rod may be a carbon fibre rod, a copper rod, an iron rod, an aluminium rod or a tungsten steel rod. An annular groove is formed at an end of the reinforcing rod. A snap ring that matches the annular groove is formed in the shaft 2, and the snap ring is engaged into the annular groove to fix the reinforcing rod inside the shaft 2. [Figure 2]
