摘要： 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.

摘要： The present invention relates to an arrow feeding device for crossbows. The feeding device positions the arrows in the feeding pall. The feeding device includes a feeding part which has a path defined through the top end and the bottom end of the feeding part. The path is defined by two sidewalls and each sidewall of the path includes a rib extending therefrom. The two ribs are located close to the rear end of the feeding part. The arrow includes two grooves defined in the tail thereof so that the two ribs of the path are received in the two grooves of the arrow. The arrow is properly positioned and restricts from shifting in the path so as to improve preciseness of shooting.

摘要： A protection device of a crossbow includes a protection coat that is mounted to the limb. The flexibility of the protection coat greater than the flexibility of the limb so that the protection coat is deformed with the limb when the limb is deformed. The protection coat absorbs vibration from the limb when the limb bounces back so as to protect the limb from being broken by reducing the vibration amplitude.

摘要： 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.

摘要： 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.

摘要： A safety device connected to a shooting device or a crossbow includes a safety member that is moved to restrict an activating member from pivoting to prevent unintentionally shooting when replacing arrows at the ready-to-shoot status of the crossbow. A resilient member is used to pull the transmission plate to move toward the second end of a case of the crossbow to deactivate the restriction to the positioning member such that the positioning member pivots and protrudes beyond a notch of the case to stop the shooting action of the string. After a new arrow is positioned, the safety member is moved again to drive the transmission plate from the second end to the first end of the case, and the activating member is released from restriction and the arrow is ready to shoot.

摘要： A pivot cover can incorporate with an ink cartridge to close an ink refill opening of the ink cartridge. The pivot cover has a cover body having a leaning portion, and a push member is extended from an end of the cover body while a fastening member is extended from another end of the cover body. The fastening member has a pivot hole. A pushing portion is disposed to an upper end of the push member while an embedding portion is disposed to a lower end of the push member, and the embedding portion protrudes the leaning portion. While pushing the pushing portion, the push member takes the pivot hole as an axle core to allow the pivot cover to rotably perform opening and closing motion so that the embedding portion can be positioned to allow the leaning portion to close the ink refill opening of the ink cartridge.
