Electric tool

An electric tool comprises a shell, a motor, a transmission mechanism and a working head are contained in the shell in the longitudinal direction, power of the working head is transmitted by the transmission mechanism, and the electric tool further comprises a rotating head mechanism arranged between the working head and the transmission mechanism. The rotating head mechanism comprises a fixed shaft and a rotating piece, wherein the fixed shaft is supported in the shell in the vertical direction perpendicular to the longitudinal direction, one end of the rotating piece is arranged on the fixed shaft in a sleeving mode, the other end of the rotating piece is movably connected with the working head, and the rotating piece is used for driving the working head to rotate around the fixed shaft. And the positioning assembly is arranged in the fixed shaft in the vertical direction and enables the rotating part to be circumferentially positioned relative to the fixed shaft. The working head can freely rotate around t
