a winding process:

referring to fig. 11-14, the string releasing member 7 is normally loose, the trigger can normally hold the bowstring 8, and the lower end of the string releasing member 7 is just limited by the limiting and clamping shaft 706, so the buckle return spring can give a left force to the string hanging buckle 2; the string hanging buckle 2 is influenced by the buckle reset spring 207 and is stressed clockwise and is in an open state, at the moment, the front end of the string hanging buckle 2 and the upper end of the arrow shaft sensing part 6 are separated from each other and opened, the bowstring 8 is pulled open through the string loading rope, the bowstring 8 touches the inner wall of the string hanging buckle 2 after entering the vertical column 204 on the string hanging buckle 2, and force is continuously exerted backwards to move, so that the string hanging buckle 2 is driven to rotate anticlockwise. In the process, firstly, the bottom 205 of the string hanging buckle 2 contacts with the inclined surface at the front end of the low-step 303 of the middle rotating piece 3, the middle rotating piece 3 is driven to rotate anticlockwise, the tail of the middle rotating piece 3 tilts upwards to push against the middle rotating piece return spring 310, then the bottom 205 of the string hanging buckle 2 continues to stretch backwards, crosses the inclined surface of the low-step 303 of the middle rotating piece 3 and enters between the low-step 303 and the high-step 305, at the moment, the string hanging buckle 2 continues to be pulled backwards by the bowstring 8, the bottom 205 of the string hanging buckle 2 enters the inclined surface of the high-step 305 until the arc surface 307 on the middle rotating piece 3 rotates for a certain angle contacts with the safety shaft 501 and is limited by the safety shaft 501, at the moment, the bowstring 8 cannot be stretched backwards continuously, namely, the anticlockwise rotation of the string hanging buckle 2 reaches the maximum range, and at the moment, the middle rotating piece return spring 310 is in a compressed state. At this time, the bowstring 8 is released, the transferring member 3 is restored to rotate clockwise after receiving the restoring elastic force of the transferring member restoring spring 310, that is, the front end of the transferring member 3 tilts upwards, the bottom 205 of the string hanging buckle 2 is clamped on the vertical surface 304 of the low-step ladder 303, and the winding process is completed. At the same time, when the string is pulled back up against the trigger, the safety ear 502 is forced back into a state of limiting the trigger actuation.

And (3) normal release process:

referring to fig. 14 and 15, when there is no arrow shaft 9, the relay 3 is always in a holding state under the influence of the relay return spring 310, since the relay 3 is located in the housing and cannot be touched by a person, the trigger can only be driven by the trigger base 4 to trigger, the arrow shaft sensing part 6 is always in an upward extending state under the action of the force of the arrow shaft sensing return spring 604, the sensing limit shaft 603 is located in the sensing circular groove 602, and the rotation of the arrow shaft sensing part 6 is limited by pulling the trigger base 4 to sense the limit shaft 603, so that the rotation of the trigger base 4 is limited; when the guard 5 is in the off condition, the bottom of the guard 5 will rest on the ramp 404 of the trigger base 4 and will also prevent the trigger base 4 from being pulled.

After putting arrow shaft 9 on, arrow shaft 9 inserts from the first buckle groove 203 of string hanging buckle 2, arrow shaft response 6 is pushed down by arrow shaft 9, response spacing axle 603 leaves response circular slot 602, arrow shaft response 6 is not limiting trigger base 4, later promote forward and open insurance 5, the bottom of insurance 5 leaves inclined plane 404 on trigger base 4, touch casing inner wall, later insurance 5 can't promote forward, later trip trigger base 4, pulley 414 on trigger base 4 drives transfer 3 and slides and anticlockwise rotation, the afterbody of transfer 3 perks upwards and is pushing against transfer reset spring 310 promptly, transfer 3 release string hanging buckle 2. The string hanging buckle 2 rotates clockwise under the action of the buckle return spring 207, the limitation on the bowstring 8 is released, and then the bowstring 8 drives the arrow rod 9 to leave the trigger to finish shooting.

When the bowstring needs to be released by pulling the string manually:

referring to fig. 17-19, after the tool pushes the string releasing ear 701 on the string releasing member 7, and pushes the string releasing ear 701 into the vertical groove 707 from the flat groove 708 on the trigger housing, at this time, the string releasing spring 704 is in a stretched state, because the string releasing ear 701 is placed in the vertical groove 707 and cannot move, the string releasing spring 704 forms a contracting tension on the fixed shaft, at this time, the string releasing spring 704 contracts to start applying a force to the retaining member 705, the force of the string releasing spring 704 is greater than the force of the buckle return spring 207, so that the retaining member 705 swings clockwise, so that the lower end of the retaining member 705 rotates clockwise, the lower end of the retaining member 705 abuts against the right-angled concave surface 306 of the high-order step 305, at this time, the upper string rope pulls the string 205 to drive the string hanging buckle 2 to rotate counterclockwise, the bottom 205 of the string hanging buckle 2 enters the high-order step 305 of the middle rotating member, contacts the inclined surface of the high-order step 305 first to force the middle-order transfer member 3 to rotate counterclockwise, and then continues to pull the string hanging 205 backwards, until the arc surface 307 on the middle transfer rope 3 touches the safety shaft 501, and is restricted by the middle transfer rope 705, the middle transfer rope to continue to rotate clockwise, after the buckle 2 rotates clockwise, the middle transfer string hanging string is released, the clamping member 705, the middle transfer rope 2 continues to be released, and the clamping member 207 to be able to be released by the clamping member 207 to slowly, and to be released by the clamping member 207, the clamping member 207 to be released arc surface 306, the clamping member 207, the clamp 2, the clamping member 207 to be released arc surface of the middle transfer rope, the clamping member 207 to be released middle transfer post, the clamping member 3, and the clamping member 207.

It should be noted that the above is only a preferred embodiment of the present invention, and the present invention is not limited to the above, and although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that the technical solutions described in the foregoing embodiments can be modified or some technical features can be replaced with equivalents, but any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
