Description

Technical Field

[0001] The utility model relates to the technical field of net guns, and in particular to a net gun device loaded on a drone. Background Art

[0002] In modern law enforcement and public safety, police often face situations requiring non-lethal means to control and capture suspects. Traditional ground-based law enforcement equipment and methods have limitations in certain complex environments, such as dense crowds, complex terrain, or areas inaccessible to ground personnel. The popularity of drones and technological advancements have provided law enforcement with a new perspective and approach. Drones can easily fly over various terrains, enter confined spaces, and conduct surveillance and operations without impacting ground traffic or personnel safety.

[0003] In the prior art, a net gun device installed at the bottom of a drone often generates a reaction force when the net gun device needs to capture a target. This reaction force often makes the drone body unstable in flight and prone to flying around, posing a danger to personnel on the ground and also causing damage to the drone body. Therefore, a device that can reduce the reaction force of the net gun device is needed. Utility Model Content
