Abstract
A crossbow includes a barrel, a retention unit, a link unit and a positioning unit. When the second link pivots toward the restriction member, the rod is moved with the slot of the restriction member, and the restriction member is pivoted relative to the second link. The pivotal action of the first link drives the retention unit to move in the arrow track and toward the bow. On the contrary, when the retention unit is connected to the bow, the second link is moved to its initial position, and the rod is engaged with the serrated portion to form a stand-by status. When the second link continuously pivots to disengage the rod from the serrated portion, the second link is engaged with the handle to form a completion status. During the cocking action, the users may have multiple stages of action to cock the crossbow.
