An electric trimmer includes: a base; and a trimmer main body configured capable of sliding movement in an axial direction of the base. The base includes a slit that extends in the axial direction and is open, and the base also includes a fixing releasing mechanism disposed so as to straddle both end portions of the slit. Operating the fixing releasing mechanism to reduce a distance between the both end portions of the slit enables clamping of the trimmer main body by the base to be performed. The fixing releasing mechanism is formed as a toggle mechanism that is configured by a combination of three support points and two links, and the fixing releasing mechanism has a shape which follows an outer peripheral surface of the base. Therefore, this electric trimmer includes high operability, strong impact resistance characteristics, and excellent maintenance properties.
