Abstract: The present invention provides an electric tool comprising a body, an operating component, an output shaft, and a stop mechanism. An arresting disc is disposed on the output shaft, and a groove is formed on the arresting disc; the stop mechanism comprises a protrusion, for example, a pin, which is operable so that the protrusion extends to insert into the groove to lock the output shaft. A stop mechanism of the present invention is easy to operate, delivers good safety performance, and has a relatively simple structure, which allows convenient production and subsequent maintenance. Further, a stop mechanism of the present invention automatically springs back to a non-stop position at which it detaches from the output shaft or the transmission gear of the transmission mechanism when the external force is lost, which prevents possible damage to the output shaft or transmission mechanism when a user starts the electric tool before releasing the stop mechanism.

Abstract: A work tool and transmission system thereof. The transmission system comprises: a first shaft (250) and a second shaft (350), a near end (351) of the second shaft having a first mating part; a shaft coupler (600), a far-side part (620) of the shaft coupler having a second mating part matched in shape to the first mating part; and a coupling mechanism capable of directly or indirectly applying a coupling force to at least one of the first shaft, the second shaft and the shaft coupler; when the far-side part of the shaft coupler is aligned with the near end of the second shaft in the circumferential direction, the coupling force forces the first mating part to engage with the second mating part, so that the shaft coupler transmits rotational movement of the first shaft to the second shaft. The work tool comprises: a transmission system; a motive power head transmission-connected to the first shaft (250); and a working head transmission-connected to the second shaft (350).

Abstract: Electric pole loppers are provided. An electric pole lopper includes a handle, a connecting pole and a pruning component which are connected in sequence, wherein the pruning component comprises a casing, a control mechanism and, connected in sequence, a motive power mechanism, a drive mechanism and a cutter set, wherein the motive power mechanism and the drive mechanism are disposed in the casing, the cutter set is disposed at that end of the casing which is remote from the motive power mechanism, a switch connected to the motive power mechanism is provided on the handle, and the control mechanism is connected to the drive mechanism; the drive mechanism is a worm gear/worm drive mechanism or a ball screw drive mechanism.

Abstract: The present utility model discloses a lighting mosquito killer lamp, which comprises a main body and a base that is joined with the main body. The main body comprises a housing, a lampshade arranged in the housing, and a high-voltage mesh wire arranged on the lampshade. The base is used for receiving power. The lighting mosquito killer lamp further comprises a lighting lamp and an ultraviolet lamp. The lighting lamp is different from the ultraviolet lamp, and the lighting lamp and the ultraviolet lamp are controlled independently of each other.
