A sheath for a power tool and a power tool

Abstract

The application discloses a sheath for electric tools and an electric tool. The sheath comprises a tubular body, at least one end of which is provided with a bent edge bent inwardly and an anti-off structure. The anti-off structure has first, second and third clamping surfaces which are sequentially and spacedly arranged along the radial direction and the axial direction. The inner end of the first and second clamping surfaces is located radially inward of the inner edge of the bent edge, the axial dimension of the third clamping surface is greater than the thickness of the bent edge, and the first clamping surface has the largest area. The structure can effectively limit the axial and radial movement of the sheath. The electric tool comprises a shell, a handle and the sheath. One end of the handle is in sliding connection with the shell, the other end is in rotary connection, and the sheath is sleeved on the outer periphery of the sliding connection part. An annular groove for accommodating the bent edge is arranged at the corresponding position of the handle and the shell. The application improves the firmness and reliability of the connection between the sheath and the tool body, effectively prevents the sheath from being off during work, and facilitates assembly.
