Power tool

Abstract

The application discloses an electric tool, which comprises a handle shell, a main shell, a connecting piece and an elastic piece; the main shell is provided with a first mounting hole; one end of the connecting piece is connected with the main shell, and the other end is connected with the handle shell; the first end of the connecting piece is inserted into the first mounting hole, and the first end of the connecting piece and the main shell are further provided with a movable gap at the first mounting hole; the elastic piece is located at the side of the connecting piece, and one end of the elastic piece is connected with the main shell, and the other end is connected with the handle shell. The elastic piece of the electric tool is connected with the main shell and the handle shell respectively, can buffer the vibration, and optimizes the user experience. Since the elastic piece bears the force transmission, the connecting piece only plays a guiding role, and the connecting piece is prevented from bearing too large load in the vibration process, so that the abrasion of the connecting piece is reduced, and the service life of the electric tool is prolonged.
