This positional relationship provides maximum tension to the bowstring 10 when the bowstring 10 is hung from the string hanging mechanism 13. The "firing exit end" is the end of the marble that is ejected in the steel column assistant, i.e., the end of the steel column assistant that is away from the handle 6. A slot 25 for mounting a sight is also provided on the firing exit end.

Bayonet 11 has been seted up to the one end of string hanging mechanism 13, pearl groove 12 has been seted up to the other end of string hanging mechanism 13, first spring hole 14 has been seted up on string hanging mechanism 13 and the opposite side of string ditch 4, has still seted up first hinge hole 15 and articulated annular hole 16 on string hanging mechanism 13, and first hinge hole 15 is close to pearl groove 12 one end, and articulated annular hole 16 is close to bayonet 11 one end, and articulated annular hole 16 is used for injecing the range of string hanging mechanism 13 around first hinge hole 15 center rotation.

The first hinge hole 15 is rotatably connected with the steel column body 1 through a first pin 17, and the hinge annular hole 16 is connected with the steel column body 1 through a second pin 18.

When the string hanging mechanism 13 rotates anticlockwise around the first pin shaft 17 until the second pin shaft 18 reaches the end of one end of the hinged annular hole 16, the position of the ball groove 12 of the string hanging mechanism 13 corresponds to the outlet direction of the ball groove 3, balls in the ball groove 3 enter the ball groove 12, when the string hanging mechanism 13 rotates clockwise around the first pin shaft 17 until the second pin shaft 18 reaches the end of the other end of the hinged annular hole 16, the ball groove 12 of the string hanging mechanism 13 sends the balls into the launching groove 2, and the bow string 10 is hooked by the string groove 4 to retreat.
