Power tool with rotatable tool holder

A power tool for performing a hammer drill operation in which a tool bit applies a linear striking force in an axial direction and a rotational force around its axis to a workpiece, comprising:

• a tool body,
• a motor,
• a tool holder that holds the tool bit in its front end region and extends in the axial direction of the tool bit,
• an elastic element,
• a striking element that is linearly driven by the motor and causes the tool bit to perform linear striking motion,
• an intermediate element that is housed within the tool holder such that it can slide in the axial direction of the tool bit and serves to transmit linear motion of the striking element to the tool bit, and
• a cylindrical rotating member that is mounted to the tool body such that it can rotate about the axis of the tool bit and rotationally driven by the motor, wherein:
• a rear region of the tool holder opposite from the front end region extends into the cylindrical rotating member, and in the extending region into the cylindrical rotating member, the tool holder is coupled to the cylindrical rotating member such that it can rotate about a pivot on a z-axis defined by a longitudinal axis of the tool bit, in directions of y- and x-axes, the y- and x-axes forming a plane perpendicular to the z-axis, while rotating together with the cylindrical rotating member about the axis of the tool bit,
• wherein the elastic element applies a biasing force to the tool holder in such a manner as to hold the tool holder in an initial position with respect to the tool body,
• wherein the tool bit is designed as a hammer bit which performs a hammering operation by applying a linear striking force to a workpiece, the power tool further comprising a second elastic element that is disposed between the tool body and the intermediate element and applies a biasing force to the intermediate element in such a manner as to hold the intermediate element in an initial position, and
• wherein the intermediate element is coupled to the tool body via a second spherical connection which is formed by a convex spherical surface centered on a pivot on the z-axis and a concave spherical surface which conforms to the convex spherical surface.
