The invention discloses an LED electric mosquito clapper with angle transformation and expansion function, which comprises a clapper frame component, at least one LED component, a support component, a grip component and a power supply component.The frame assembly is a ring structure, and the inner part of the frame assembly is provided with a net catching device.At least one LED assembly is a ring structure and is located on the inner wall of the frame assembly.The support component is a telescopic structure and is in the shape of a rod. One end of the support component is connected to the racket component. There is a predetermined included angle between the racket component and the support component. When the racket component gradually approaches the support component under external force, the predetermined included angle gradually decreases, while when the racket component gradually moves away from the support component under external force, the predetermined included angle gradually increases.The grip assembly is a shell structure and is connected to the other end of the support assembly.The power supply assembly is located inside the grip assembly, and is electrically connected with the screen catcher and at least one LED assembly.Wherein, when the power supply component supplies electric energy to the screen catcher and at least one LED component, at least one LED component generates a preset light color beam, and the body of the screen catcher is in a conductive state.本創作係揭露一種具角度變換與伸縮功能之LED電蚊拍,其包含拍框組件、至少一LED組件、支撐組件、握柄組件與電源組件。拍框組件為環形結構,拍框組件之內部具有捕網件。至少一LED組件為環形結構,並位於拍框組件之內壁。支撐組件為伸縮結構,並呈桿狀,支撐組件之一端連接於拍框組件,其中,拍框組件與支撐組件之間具有預定夾角,在拍框組件受外力而逐漸趨近支撐組件時,預定夾角則逐漸變小,而在拍框組件受外力而逐漸遠離支撐組件時,預定夾角則逐漸變大。握柄組件為殼體結構,並連接於支撐組件之另一端。電源組件位於握柄組件之內部,並電性連接捕網件與至少一LED組件。其中,在電源組件供給電能至捕網件與至少一LED組件,至少一LED組件則產生預設光色之光束,且捕網件之本體呈導電狀態。
