BALL BEARING COMPOUND BOWCompound Bow Design Concept
Combine the bow body and the long pole together to form a compound bow that can fire steel balls. It adopts a leather band power system with a pulley sliding structure for smooth firing and stable power output. The rubber band connects the steel wire bowstring, which is convenient for the release device to catch the steel string. With the small pulley on the bow body, the long rod can slide back and forth quickly, and the trigger can be pulled to release the steel ball quickly.
