A crossbow includes a rail and an arrow retention device including a bridge, a supporting element, a rolling unit, and two springs. The bridge includes a first section connected to the rail and a second section extending over the rail. The supporting element is connected to the second section of the bridge. The supporting element includes a pocket intersecting a bore. The rolling unit includes a roller and an axle. The axle includes a middle section for supporting the roller and two lateral sections extending from the roller. The lateral sections of the axle are located in two portions of the bore divided by the pocket. The roller includes a portion located in the pocket and another portion extending from the pocket to contact an arrow. The roller includes a smooth periphery. Each of the springs is compressed between the bridge and one of the lateral sections of the axle.

A stock assembly of a crossbow includes a fore-end stock, a butt stock, and a lock. The fore-end stock includes a slot in a lateral face and a chamber in a rear face. The slot is in communication with the chamber. The butt stock includes an insert movably inserted in the chamber, a shoulder contact portion formed at an end of the insert out of the chamber, and recesses in a lateral face of the insert. The lock is pivotally connected to the fore-end stock and insertable in a selected one of the recesses through the slot.

A cocking mechanism is disclosed. The cocking mechanism comprises an actuator assembly, a hand crank assembly, and a bow string hook assembly. The actuator assembly further comprises clutch assembly having a bearing housing, a bearing cage, a support axle and bearing elements. The bearing housing is defined by an inner peripheral surface having a plurality of inwardly extending annular ramps, wherein the bearing elements contact a portion of the ramps to prevent rotation of the support axle in a first direction, but allows for rotation of the support axle in a second direction when the actuator assembly is in a locked configuration. This provides for immediate braking action against any unforeseen forward motion of the bow string of a crossbow such as when inadvertently or accidently releasing the removable hand crank assembly during the cocking operation.

A crossbow with a movable trigger latch block. The crossbow has a trigger latch block slidingly connected to the flight track. The trigger latch block is configured to engage and retain the bowstring. A cocking mechanism is configured to draw the trigger latch block with the bowstring from an initial position near a forward end of the flight track to a cocked position. A one-way retention mechanism is configured to immobilize the trigger latch block against linear movement in a forward direction along the flight track. A trigger-traverse mechanism is configured to slide the trigger latch block in a forward direction to its initial position after the bowstring is released.
