Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is related to a continuous shooting device with a controllable arrow chain structure, and particularly to the technology applied in the field of shooting.

2. Description of the Related Art

In the early shooting sports, bullet shooting devices have continuous shooting structures, such as magazines or bullet chains; for example, Taiwan new model patent No. M627524 discloses a bullet chain in a simulated bouncing chain structure of a toy gun. However, in the shooting sport of bows and arrows, the user must draw and mount bows and arrows one by one before shooting.

The shooting devices using bows and arrows do not have the above-mentioned bullet chain. Some manufactures developed new type of arrow boxes, for example, TW invention patent No. I738463 discloses a crossbow arrow loading device enabling a user to perform continuous shooting operations. However, compared with the bullet chain, the conventional arrow box has several shortcomings, first the number of shots is limited by a height of the arrow box, the number of bows and arrows that the arrow box can hold is limited, and the heavy arrow box loaded too many arrows also increases the user's burden on operation; secondly, the disassembly operation of the arrow box is too time-consuming, and it undoubtedly affects the user's concentration and stability in shooting.

SUMMARY OF THE INVENTION

An objective of the present invention is to increase the number of arrows and maintain the stability and accuracy of continuous shooting, and provide an operation that is more simple and easy to use, so that a user just needs to directly put an arrow chain with multiple arrows into the continuous shooting device and then starts shooting.

In order to achieve the objective, the present invention provides a continuous shooting device with a controllable arrow chain structure. The continuous shooting device includes a shooting body, a belt chain assembly, an arrow driving assembly, a string firing assembly, and a driving assembly. The shooting body has a driving chamber disposed therein, and a chain hole cut through a side of the shooting body to other side of the shooting body to connect the driving chamber. The belt chain assembly is disposed in the driving chamber, and includes a driving block configured to engage with an arrow chain, and a slider assembly configured to control movement of the driving block, wherein the driving block corresponds in position to the chain hole and is movably engaged with the arrow chain. The arrow driving assembly is disposed in the driving chamber, and includes a push shaft, an arm assembly, and a push arm, wherein the push shaft is movably disposed in the driving chamber and adjacent to the slider assembly, a moving direction of the push shaft is the same as a moving direction of the slider assembly, an end of the arm assembly is mounted with two ends of the push shaft and extended toward the driving block, and the other end of the arm assembly is pivoted with an end of the push arm, the other end of the push arm is pivoted with the driving chamber, movement of the push shaft makes the arm assembly drive the push arm to longitudinally swing, and the end of the push arm that is pivoted with the arm assembly is longitudinally swung toward the arrow chain, wherein when the push arm is swung, arrows on the arrow chain are pushed to escape and fall on a top surface of the push arm. The string firing assembly is disposed in the driving chamber, and includes a string configured to push the slider assembly to move. A part of the driving assembly is disposed in the driving chamber, another part of the driving assembly is disposed outside the shooting body, the driving assembly includes a track rod assembly and a sliding member assembly, the track rod assembly is fastened in the driving chamber, and a part of the sliding member assembly is assembled with the track rod assembly and movable along the track rod assembly close to or away from the slider assembly, another part of the sliding member assembly that is disposed in the driving chamber further comprises a carrying portion configured to clip the string, and a pushing portion configured to push the push shaft to move.
