The invention provides an electric tool with a rotatable multi-lamp lighting structure. The electric tool comprises a tool casing and a torsion cover assembly which are connected with each other. The torsion cover assembly is provided with a lighting device, and the lighting device comprises a circuit board and further comprises two conducting rings and two elastic conducting pieces, wherein the two conducting rings abut against the two elastic conducting pieces. The two conducting rings are fixedly arranged at one end of the torsion cover assembly close to the tool casing and are electrically connected with the circuit board, and the two elastic conducting pieces are fixedly arranged in the tool casing and are electrically connected with a switch in the tool casing. The electric tool with the rotatable multi-lamp lighting structure is simple in structure, convenient to use, high in reliability, insusceptible to space limitation, low in manufacturing cost and good in lighting effect.
Description
technical field [0001] The invention relates to an electric tool, in particular to an electric tool with a rotatable multi-lamp lighting structure. Background technique [0002] With the continuous development of electric tool products, people's requirements are getting higher and higher, and it is usually hoped that one electric tool can achieve the combined effect of several tools. At present, in many electric tools (such as ordinary electric drills, impact electric drills, electric screwdrivers, electric wrenches, electric impact wrenches, electric impact screwdrivers, electric circular saws, electric curve saws, electric electric grinding heads, electric edge trimmers, etc.) LED lights are installed as auxiliary lighting, usually with one LED light, and the position is fixed. In this case, the connection between the lamp and the power supply end can be realized by simply connecting the wire, but usually the auxiliary lighting effect of this kind of LED lamp is poor, and...
