The utility model relates to the technical field of sports goods, specifically, relates to a bow. The bow comprises a bow body, the bow body is installed with a bowstring, the bow body is installed with a push-pull rod capable of moving forwards and backwards, the push-pull rod has a launching channel extending in the forward and rear direction, the front end and both sides of the launching channel are open, the bowstring passes through the side of the launching channel, and the push-pull rod is installed with an operating device for fixing and releasing the bowstring. The application has the advantages that: 1, the combination of the push-pull rod and the operating device is used to pull and release the bowstring, which is more convenient and less likely to hurt the hand compared with directly pulling the bowstring with the fingers in the traditional method; 2, arrows or projectiles are launched through the launching channel, are guided through the launching channel, are convenient to aim at, have higher precision, and are favorable to improving the result.

The present application relates to the field of unmanned aerial vehicle defense, and discloses a method for determining attack sequence of unmanned aerial vehicles, an electronic device and a defense system. The method for determining attack sequence comprises: predicting a first predicted time length when an unmanned aerial vehicle reaches a preset protection boundary, predicting a second predicted time length when the unmanned aerial vehicle reaches a radar detection blind area, determining a target threat level according to the first predicted time length and the second predicted time length, and determining an attack sequence of each unmanned aerial vehicle according to the target threat level of each unmanned aerial vehicle. Therefore, the present embodiment can determine the threat degree of each unmanned aerial vehicle according to the time when each unmanned aerial vehicle will reach the preset protection boundary and the time when each unmanned aerial vehicle will reach the radar detection blind area, and automatically determine the attack sequence according to the threat degree, which is beneficial for a user to aim at each unmanned aerial vehicle according to the attack sequence, shorten the attack decision time, and reduce the attack difficulty, thereby being beneficial for implementing effective attack on each unmanned aerial vehicle in turn before the unmanned aerial vehicles intrude into the preset protection boundary or cross the radar detection blind area.
