Guided by the inclined surface 43211, the hook arm 432 compresses the hook arm spring 433, and swings toward the avoidance position, so that the hook portion 4321 is disengaged from the hook arm groove 431.

And by the reaction force of the hook arm spring 433, the hook portion 4321 is pressed against the horizontal fin of the cross tail 51 by a pre-pressure to achieve the purpose of clamping the bow 500, and the bow and arrow 500 is not avoided when the crossbow is placed downward. Will fall due to self-weight. In this way, the second heavy insurance can be automatically released by the action of the upper arrow.

In addition, the upper portion of the vertical fin of the crosshead 51 of the bow 500 will pass through the first tail slot 146 of the shoe door 14 (the door body 141) and the retreat slot 4322 of the hook arm 432 (hook portion 4321). The upper portion can be directly accessed because the arrow groove 111 communicates with the operation chamber 122 of the grip portion 12 in the lower stage. Through the height adjustment of the first tail section slot 146, it is possible to limit the height of only the matching cross tail 51 to the upper arrow. In addition to ensuring the singleness of the bow 500, it is possible to avoid misuse or mistake the bow 500 of another person.
