An arrow feeding device for a crossbow includes a magazine mounted to the crossbow and includes a storage space which opens through the magazine from the top to the open bottom of the magazine. Multiple arrows are loaded in the storage space. A retainer is pivotably connected to the magazine and normally presses the arrows in the storage space so that the lowest arrow of the arrows in the storage space is fed into the barrel of the crossbow in sequence. The users shoot the arrow without repeatedly lowering the crossbow and loading the arrows.

A crossbow includes a body includes a connection part that includes a clamping portion. The clamping portion includes two side plates, and a space is formed between the two side plates. A bow unit includes a bow and a block which is formed to the middle portion of the bow. The block includes a protrusion which is accommodated in the space and clamped between the two side plates so as to connect the bow unit to the connection part. A magazine includes the first end thereof pivotably connected to the body, and the second end of the magazine is connected to the clamping portion. The magazine includes two lugs between which the clamping portion is located. A pin extends through the two lugs, the two side plates and the block to connect the magazine to the body. By removing the pin and pivoting the magazine, the bow unit is replaced.

A crossbow includes a body having a grip and a connection end respectively formed to two ends of the body. A connection part is formed to the connection end and includes a clamping portion and a top portion. The top portion includes a guide face firmed to the top thereof. A bow unit includes a bow and a block which is formed to middle portion of the bow. A string is connected between two ends of the bow. The block is detachably connected to the clamping portion to transversely position the string above the guide face. A magazine includes a mounting member located corresponding to the clamping portion. The magazine is detachably connected to the body to form a room between the guide face and the magazine for movement of the string. The magazine is secured to the body by the mounting member.

The disclosed technology includes a semi-automatic crossbow having a stock, a plurality of limbs, a drawstring, a bolt feeder, a barrel, a draw assembly, and a release. The draw assembly can be configured to automatically move the drawstring to a cocked position and the release can include a trigger and be configured to release the drawstring when the trigger is actuated. The disclosed technology can further include a truck configured to engage the drawstring and a bolt such that the bolt can be propelled forward by the truck when the drawstring is released by the release.

A repeating crossbow having a pump-action reloading mechanism. The crossbow includes an elongated body with a shooting track and a holding chamber configured to house one or more projectiles. A hatch is coupled to the body and configured to move between a first position aligned with the shooting track and a second position at least partially aligned with the holding chamber. A palm rest is slidingly connected to the elongated body. Sliding the palm rest in a rearward direction causes the hatch to move from the first position into the second position. A biasing member within the holding chamber ejects a projectile onto the hatch. Sliding the palm rest in a forward direction to return to its default position causes the hatch to return to its first position, bringing the projectile into alignment with the shooting track.

A nock for an archery arrow or bolt. The nock includes a radial indention configured to be engaged by a biased retainer of a trigger mechanism of a crossbow to retain the arrow or bolt in a desired position relative to the trigger mechanism and/or a bowstring. The radial indention may optionally comprise a groove defined generally continuously around a circumference of the nock. The radial indention is exposed when the nock is coupled with an arrow or bolt such that the radial indention may be engaged by a biased retainer within the trigger mechanism. The nock may further include a generally planar rearward bearing surface configured for being engaged by a bowstring. The nock of the present invention may be suitable for use with a multiple-shot crossbow or a single-shot crossbow. Other aspects of the present invention are directed to a projectile, a projectile retention system, and a crossbow.

A crossbow includes a magazine mounted to the top of the crossbow and the magazine includes a storage space defined through the top and the bottom top of the magazine, and the storage space communicates with the flight rail of the crossbow. Multiple arrows are loaded in the storage space. The magazine includes two first engaging members which are removably engaged with two second engaging members formed on the top of the crossbow. Two protrusion respectively extend inward from two inside walls of the storage space to restrict and guide this arrows in the storage space. A retainer has a first end thereof connected to the magazine and a resilient member is located in the storage space and biases between the retainer and the inside of the storage space such that the retainer normally pressing the arrows in the storage space.

A multiple-shot crossbow includes a mainframe, a riser, upper and lower bow limbs and bowstrings, and a trigger mechanism. The mainframe includes upper and lower rails, each for supporting and guiding a corresponding bolt. The riser includes a passage for accommodating loading and launching a bolt. The bow limbs are attached to the riser and the bowstrings are attached to the bow limbs. Each bowstring is arranged independently to be drawn from a brace position to a drawn position and then return to the brace position while launching a bolt positioned on the corresponding rail. The lower bowstring is movable within a longitudinal slot between the upper and lower rails. The trigger mechanism is attached to a rear end of the mainframe and includes upper and lower trigger portions, each retaining a corresponding drawn bowstring and then releasing it upon actuation by a user.
