A fixed blade, two-blade broadhead for use on a hunting arrow that employs multiple, flat surface facets that automatically hold the correct bevel angle for edge sharpening when the broadhead is placed upon a sharpening stone.

Arrow chain structure, including: several arrow chain bodies (2), each having a base (20), wherein one side of the base (20) is provided with an arrow receiving recess (23) and a pivoting part (25), and the other side of the pivoting part (25), which is not provided with an arrow receiving recess (23), is provided with a receiving recess (220); several extension parts (3), each having a receiving end (30) and a pivoting end (31), wherein a receiving end (30) is housed in the corresponding receiving recess (220) and a pivoting end (31) is pivotably connected to the corresponding pivoting part (25); wherein, after the extension parts (3) have been combined with the corresponding arrow chain bodies (2), all arrow chain bodies (2) are pivotably connected to each other by the pivot parts (25) to form a chain-like arrow chain structure.

Crossbow bolt for repeating crossbows with magazine, characterized in that the bolt is formed in two parts and has a tubular shaft (2) made of carbon fiber reinforced material and a coaxially arranged solid end element (3) made of carbon fiber reinforced material, wherein the end element (3) has a positioning notch (5) incorporated into the solid material for positive locking in the magazine and wherein the shaft (2) and end element (3) have essentially the same outer diameter.

A molded arrow assembly preferably includes an insert and an outsert for an arrow or an insert / outsert assembly. The molded arrow assembly may include an insert having a cylindrical body with a first end and a second end. The second end may be dimensioned to fit within a bore of an arrow shaft. The first end may terminate in a prong containing male threads. The insert / outsert assembly may also include an outsert having a cylindrical wall with an arrow shaft end and an arrowhead end. The cylindrical wall may also include a center bore extending between the arrow shaft end and the arrowhead end. The center bore may contain a threaded region containing female threads. The threaded region may be located intermediate of the arrowhead end and the arrow shaft end and may extend between a top shoulder and a bottom shoulder.

This utility model discloses a drop arrow for killing wild boars using a drone, relating to the field of drone accessory technology. The utility model includes an arrow shaft with an arrowhead on one side and fletching on the other side. A fixing component is provided on one side of the arrow shaft, including a mounting post installed on the side of the arrowhead. This utility model significantly improves the flexibility and adaptability of the drop arrow through modular design. The detachable connection structure between the arrow shaft and the arrowhead allows for quick replacement of the arrowhead or adjustment of the counterweight, thereby precisely adjusting the striking force for wild boars of different sizes. The counterweight is fitted onto the surface of the arrow shaft, and the weight can be increased or decreased according to actual needs, avoiding the drawback of traditional one-piece drop arrows that require complete replacement. The design of the fixing sleeve and the fletching ensures flight stability, while the interlocking structure of the square groove and the square post further prevents fletching deviation, ensuring the drop arrow maintains a precise trajectory after deployment and effectively improving the hunting success rate.

Device for applying three helical feathers, spaced 120°, to an arrow shaft, commonly used in archery practice, characterized in that it comprises a central casing (3) with an aperture in its center and a cylinder (2) with two cable grommets at its ends, said cylinder being attached to the casing (3), through which the user passes the arrow shaft (1) and locks it in the desired position by tightening the nuts of the double cable grommets; and three articulated arms (6) attached to the upper surface of the casing (3) at 120° intervals, with two plates - one integral with the arm (6) and the other (5) attached to the arm (6) - spaced apart by a narrow gap into which the feather (4) can be inserted and prepared for gluing, and the arms are joined at their lower ends around a transverse axis, which enables the user to pivot the arms (6) until the feather (4) comes into contact with the arms (6) and remains adhered to them due to the double-sided adhesive previously applied to them.

A device intended to apply, onto arrow shafts commonly used in the practice of archery, three helicoidal feathers at intervals of 120°, distinguished by the fact that it comprises a central housing with an orifice at its center, a double compressing cable gland, through which the user passes an arrow shaft and locks it in the desired position, and three articulated arms attached to the upper surface of housing at 120° intervals. The arms have two plates—one integral to arm and the other attached to the latter—spaced by a narrow gap in which a feather may be inserted and prepared for gluing, and jointed at their lower end around a transverse axis that enables the user to pivot the arms until the feather comes into contact with the shaft and remains adhered to the shaft thanks to double-sided adhesive applied to the feather.

An archery arrow is provided to include a shaft that is tubular and includes an exterior surface and an opposing interior surface, with an insert secured to the shaft. The insert can define a hole configured to join a component, for example, a broadhead with the arrow. The hole can be round and concentric with the exterior surface of the shaft, and in some cases non-concentric with the interior surface. The insert can be adhered to the shaft and later machined to define the hole to provide the concentricity of the hole and the shaft exterior or an associated outer diameter. When a component such as a broadhead is joined with the arrow via installation in the hole, the component can be centered relative to the shaft exterior. A related method of manufacturing an arrow is provided.

Device intended to install on arrow tubes commonly used in the practice of archery three helical fletchings at 120° intervals, characterized in that it comprises a central housing (3) with an orifice in its center and a cylinder (2) equipped with two cable glands at its ends, fixed on said housing (3), through which the user passes the arrow tube (1) and locks it in the desired position by tightening the nuts of the double cable gland;and three articulated arms (6) fixed to the upper face of the housing (3) at 120° intervals, having two plates – one integrated into the arm (6) and the other (5) fixed to it – separated by a thin gap into which the nib (4) can be inserted and prepared for gluing, and articulated at their lower end around a transverse axis allowing the user to rotate said arms (6) until the nib (4) comes into contact with it and remains glued there by means of the double-sided adhesive previously applied to it.
