摘要
An expandable arrow broadhead used for releasable attachment to one end of a hollow arrow shaft. The broadhead includes a sliding shaft with a pointed tip and tip base having two or more of cutting blades mounted thereon. Each of the blades includes an outer cutting edge and an inner edge. A portion of the sliding shaft is slidably received inside a hollow collar. The collar is attached to a sliding shaft housing. The sliding shaft housing is attached to an arrow shaft insert. The arrow shaft insert is adapted for receipt inside one end of the arrow shaft. In a retracted position, the blades are disposed next to and parallel to the length of the sliding shaft. When the pointed tip engages a target, the sliding shaft moves inwardly and rearwardly sliding inside the collar and inside a sliding shaft bore hole in the sliding shaft housing. As the sliding shaft moves rearwardly, a beveled cam surface of the blades engages a portion of the collar, which moves the blades outwardly into an extended position.
