Detailed ways

The present invention will be described in detail below with reference to the drawings.

As shown in FIGS. 1 and 2, the present invention includes a bow and a bowstring, and is also provided with a wooden bracket 6, a mobile launching mechanism 1, and an arrow box 2 with an arrow slot 14 and an arrow path 10 therein, where the bracket 6 is installed There are an arrow box 2 and a bow string 5 and a bow 8, and the mobile launching mechanism 1 is movably connected to the bracket 6 and the arrow box 2 respectively;

Wherein: the mobile launching mechanism 1 is composed of two support rods, and one end of the two support rods is connected together (available Fixed sleeve connection), the other is movably connected to the bracket 6 respectively, and an arrow box 2 is sleeved between the two support rods, and is movably connected to it; the arrow slot 14 is longitudinally provided in the arrow box 2, The opening is located at the upper mouth of the arrow box 2. The bottom of the arrow slot 14 extends below the arrow box 2. Below the arrow slot 14, an automatic firing string slot 4 is provided. The front end of the automatic firing string slot 4 projects below the arrow slot 14 to form a string. The slideway is provided with a groove 16 at the rear end, and a movable pin 3 is provided in the groove 16. The movable pin penetrates the bottom of the groove 16 and dynamically contacts the bracket 6. The automatic transmission chord groove 4 is parallel and penetrates. It is provided on both side walls of the arrow box 14; 'The arrow path 10 is provided in the arrow box 2, one end of which communicates with the lower part of the arrow box 14, and the exit end is provided on the front surface of the arrow box 2.
