For a more detailed understanding of the embodiments of the present invention, please also watch it together with the drawings. First, as shown in the first to second drawings, it is a bow and arrow device, which includes: a gun body 1, which has a connected slide section 11. A head section 12, wherein the head section 12 has a main body part 121, the main body part 121 is connected with the slideway section 11, and an extension part 122 extends from two sides of the main body part 121; two pulleys 2, which pivot respectively; Set at the end of each extension 122; the two bow arms 3 respectively have a body end 31 and a string end 32 that are far away from each other. The end 32 is closer to the head section 12 than the corresponding link end 31 (the shortest distance between the link end 32 and the head section 12 is less than the minimum distance between the link end 31 and the head section 12); a main string 4, its two ends They are respectively connected to the two pulleys 2;

The bow arms 3 are all made of elastic materials.

Continuing the above content to further describe the embodiment of the present invention, it can be seen from the first figure that the pulley 2 is provided with the head section 12, not the bow arm 3, and the pulley 2 determines the setting position of the main string 4. Therefore, the pulley 2 is no longer arranged on the structure of the bow arm 3, so that the main string 4 can be arranged at the front end of the gun body 1 as much as possible, so that the distance from the buckle portion 123 to the end of the head section 12 can be converted into Stroke, compared with the conventional products, the present invention indeed maximizes the length of the gun body 1 and converts it into a stroke, and the body end 31 is farther away from the head section 12 than the string end 32. , the center of gravity of the present invention is more inclined to the operator's body, so as to reduce the burden on the operator's arms. Combining all the above, it can be seen that the present invention is novel and advanced compared with conventional products.

As shown in the second figure, the two bow arms 3 are respectively bent in the direction away from the slideway section 11, and the chord end 32 of each bow arm 3 will swing in the direction of approaching the slideway section 11 when the bow arm 3 is wound. Therefore, The structure of the bow arm 3 bent away from the slideway section 11 maximizes the energy storage.

As shown in Figures 3 and 4, an imaginary plane P1 extends horizontally from the top of the slideway section 11 to the peripheral side, and the two sub-strings 5 are parallel to the imaginary plane P1. The advantage of this structure is that the arrows are fired so that each When the bow arms 3 are swayed, the adverse effects on the firing path of the arrows when the bow arms 3 are deflected can be minimized (for example, the firing paths of the arrows are shifted upwards and downwards).

The present invention also provides another embodiment, as shown in Figures 5 and 6, which is a bow and arrow device, which includes: a gun body 6, which has a slideway section 61 and a head section 62 connected to each other, wherein the The head section 62 has a main body part 621 which is connected with the slideway section 61 , an extension part 622 extends from two sides of the main body part 621 respectively; Two bow arms 8, which respectively have a connecting body end 81 and a connecting string end 82 that are far away from each other, each connecting body end 81 is respectively connected to the two sides of the main body portion 621, and each connecting body end 81 is more flexible than each pulley 7. Approaching the slideway section 61, each string end 82 is farther away from the head section 62 than the corresponding link end 81 (the shortest distance between the string end 82 and the head section 62 is greater than the minimum distance between the link end 81 and the head section 62). ), and the two bow arms 8 are respectively bent toward the direction close to the slideway section 61; a main chord 9, The two ends are respectively connected to the two pulleys 7 ;

Compared with the previous embodiment, the main difference between this embodiment is that the arrangement of the bow arm 8 is different, and the pulley 7 is also arranged on the head section 62, so that the distance from the buckling portion 623 to the end of the head section 62 can be converted into a stroke , Compared with the conventional product, this embodiment can indeed maximize the length of the gun body 6 into a stroke. Combining all of the above, it can be seen that this embodiment is also novel and progressive compared to the conventional product.

Further as shown in Fig. 7, the slideway section 61 and the head section 62 are connected in a removable and detachable manner, this structure is used to make the maintenance of the present invention more convenient, and because each bow arm 8 is connected It is convenient for the head section 62 to be separated from the chute section 61 without removing any strings.

As shown in Figures 8 and 9, each string end 82 is connected to each auxiliary string 10 by a set of peg wheels 821, and the top of the slideway section 61 extends horizontally to the peripheral side with an imaginary surface P2. The two auxiliary strings 5 are all parallel to the imaginary plane P2. The advantage of this structure is that when the arrow is fired so that each bow arm 8 is swayed, the adverse effect on the arrow firing path when each bow arm 8 is swayed can be minimized (for example, the arrow The firing path is offset up and down).
