Referring to the accompanying drawings, the one-plus-two type three-thorn anti-off fish dart includes a dart shaft 2, and the upper end of the dart shaft 2 is provided with a sharp dart tip 1, which can be conical or triangular pyramid-shaped; secondly, the dart The lower end of bar 2 is provided with the threading hole 15 that is used for dressing thread, is tied with thread in the threading hole 15, and the other end of thread is tied on people's wrist or on other positions, therefore, facilitates the present invention from secondly, in order to make the weight of the head of the dart shaft 2 greater than the weight of the tail of the dart shaft 2, the dart shaft 2 includes a dart tip section 10 at the upper end and a dart tail section 11 at the lower end of the dart tip section 10, Wherein, the diameter of the dart head section 10 is larger than the diameter of the dart tail section 11; in addition, after the present invention is injected into the fish body, in order to remove the fish from the dart shaft 2 quickly, the dart shaft 2 of the present invention is preferably Two sections of the shaft are combined. For example, as shown in Figure 2, a threaded hole can be set at the lower end of the dart head section 10, and the dart tail section 11 is directly screwed into the threaded hole. Therefore, it is only necessary to put the dart The dart head section 10 is separated from the dart tail section 11, and the fish on the dart head section 10 can be pulled down from top to bottom. Of course, as shown in Figure 4, the present invention preferably sets the dart head section 10 into two parts. Segment rod body structure, that is, the dart head rod segment 10 includes an upper rod segment 12 at the upper end and a lower rod segment 13 screwed at the lower end of the upper rod segment 12 . In addition, in order to improve the flight accuracy of the present invention, it is preferable to install the dart blade 14 on the lower end rod section of the dart tail section 11 .

Continuing to refer to the accompanying drawings, the upper rod section 12 of the present invention is first provided with a dart hook groove 3, as shown in Figure 4, the dart hook groove 3 is opened at the rear side of the upper rod section 12 from bottom to front and upward The open groove, when ejecting the present invention, first hangs the bowstring in the dart hook groove 3, then pulls and releases the tail of the present invention in an instant, thereby the present invention is ejected.

In addition, an upper barb 4 and a left barb 5 and a right barb 6 at the same height are sequentially hinged on the upper bar section 12 from top to bottom, wherein the hinged axis of the upper barb 4 is higher than the dart hook groove 3 set, and the hinged axis of the left barb 5 and the right barb 6 is set lower than the dart hook groove 3; in addition, the upper barb 4, the left barb 5 and the right barb 6 are arranged around the axis of the dart shaft 2 between each other The included angle is at least 90 degrees, for example, the angle between the upper barb 4, the left barb 5 and the right barb 6 can be 120 degrees; however, the present invention installs the upper barb 4 and the left barb for convenience 5 and the right barb 6, preferably the hinge axis of the left barb 5 and the right barb 6 is parallel or coaxially arranged, while the hinge axis of the upper barb 4 is perpendicular to the hinge axis of the left barb 5. As shown in Figures 1-5, the left barb 5 and the right barb 6 are symmetrically arranged along the axis of the dart shaft 2, while the upper barb 4 is hinged on the front side of the dart shaft 2. Secondly, the dart hook groove 3 is opened On the rear side of the dart shaft 2. In order to realize the hinged structure of the upper barb 4, the upper end of the upper rod section 12 is provided with an upper hinged groove 7 that runs through the dart shaft 2 front and rear, and the upper groove surface of the upper hinged groove 7 extends upwards to the dart tip section. The lower groove extends downwards to the approximate middle of the dart hook groove 3. In addition, the upper rod section 12 is provided with horizontal hinge holes that run through the upper rod section 12 and the upper hinge groove 7. The horizontal hinge holes are close to the upper hinge hole. The top of the groove 7 is provided, and the inner end of the upper barb 4 is provided with an upper hinged hole used in conjunction with the transverse hinged hole. Therefore, the upper barb 4 passes through the longitudinal hinged hole and the upper hinged hole. The hinge shaft is installed in the upper hinge groove 7. In addition, the upper barb 4 is a thorn piece with the hinge width at the inner end and the width of the tail gradually becomes smaller to a spike-like structure. The left and right thickness of the thorn piece is smaller than the upper hinge groove. 7; secondly, the upper barb 4 can swing around the hinge axis to the upper side away from the dart shaft 2 to a set angle so as to be in the unfolded state, as shown in Figure 5, when the upper barb 4 is in the unfolded state, it is roughly It is vertically arranged with the dart shaft 2, and the upper barb is limited by the upper edge of the upper hinge slot 7 to block the upper barb in the unfolded state; in addition, the upper barb 4 swings back to the upper hinge slot 7 to realize folding state, and the tail of the upper barb 4 that swings to the folded state is located outside the front notch of the upper hinged groove 7. Of course, it is only necessary to make the distance between the bottom surface of the upper hinged groove 7 and the longitudinal hinge axis less than that of the upper hinged groove. The distance between the tail of the thorn 4 and the longitudinal hinge axis is sufficient. Therefore, the tail of the upper barb will be blocked outside the front notch by the lower edge of the upper hinge slot.

Secondly, in order to realize the hinged structure of the left barb 5 and the right barb 6, the upper rod section 12 located on the lower side of the dart hook groove 3 is provided with a lower hinged groove 8 that runs through the dart shaft 2 left and right. The upper groove surface of the groove 8 can extend upwards to the dart shaft 2 section on the front side of the dart hook groove 3, so that the installation positions of the left barb 5 and the right barb 6 are set as close as possible to the dart tip 1; in addition, the upper shaft section 12 is also provided with a longitudinal hinged hole that runs through the upper bar section 12 and the lower hinged groove 8. This longitudinal hinged hole is arranged near the upper groove surface of the lower hinged groove 8. and the inner end of the right barb 6 are all provided with a lower hinged hole cooperating with the longitudinal hinged hole, therefore, the left barb 5 and the right barb 6 pass through the longitudinal hinged hole and the lower hinged hole. The shaft 9 hinges the left barb 5 and the right barb 6 in the lower hinged hole. In addition, the outline shape of the left barb 5 and the right barb 6 is roughly the same as that of the upper barb 4. However, the left barb 5 and the right barb The sum of the front and rear thicknesses of the barb 6 should be less than the front and rear groove width of the lower hinged groove 8. Secondly, the left barb 5 can swing out from the left notch of the lower hinge slot 8 around the hinge axis to a set angle so as to be in an unfolded state; The right notch swings out to the set angle so as to be in the unfolded state; as shown in Figure 2, when the right barb 6 and the left barb 5 are in the unfolded state, they are arranged perpendicularly to the dart shaft 2, and the left barb and the right The barbs are limited by the upper side of the lower hinged slot 7 to block the left barb and the right barb in the unfolded state; secondly, the left barb 5 and the right barb 6 are swung back to the lower hinged slot 8 to realize In the folded state, the tail of the left barb 5 that swings to the folded state is located outside the left notch of the lower hinge slot 8, and the tail of the right barb 6 that swings to the folded state is located outside the right slot of the lower hinge slot 8. Of course, it is only necessary to make the distance between the groove bottom surface of the lower hinged groove 8 and the transverse hinge axis less than the distance between the tail of the right barb 6 and the left barb 5 and the distance between the transverse hinge axis. Therefore, the right barb 6 And the afterbody of left barb 5 can be blocked on the outside of corresponding notch by the lower edge of lower hinged groove 8. Then, when the upper barb 4, the left barb 5 and the right barb 6 are inserted into the fish with the dart shaft 2 or pass through the fish, if the dart shaft 2 is dragged, then the three barbs will be laid out with the fish, so that The fish is firmly limited on the dart shaft 2.

After the above-mentioned structure is adopted, at first, only one upper barb 4 is arranged on the upper side of the dart hook groove 3, therefore, the resistance to piercing the flesh caused by the upper barb 4 is small, and then it is ensured that the present invention can also be used when shooting fish. The left barb 5 and the right barb penetrate or penetrate the fish smoothly, so that all three barbs can play a position-limiting role, and then fully limit the fish on the dart shaft 2; Only one upper barb 4 is set on the upper side, therefore, the space reserved for installing the upper barb 4 at the upper end of the dart shaft 2 is small, and then the dart hook groove 3 can be set as close to the dart tip 1 as possible, even if the practical The string hanging position is as close as possible to the tip 1 of the dart, so the shooting accuracy of the present invention can be guaranteed, and the probability of shaking or swinging can be reduced; finally, since the mutual angle between the three barbs is at least 90 degrees, it can improve The probability that the barb hook hangs on the fishbone or fishbone, and then prevents the barb from coming out from the gap between the fishbone or fishbone, thereby preventing the fish from falling off from the dart shaft 2.

To sum up, the present invention is not limited to the above specific embodiments. Those skilled in the art can make several changes and modifications without departing from the spirit and scope of the present invention, and all these changes should fall within the protection scope of the present invention.
