The present invention provides a hand-held electric tool comprising a housing and an operating component. The housing has a main body section and a grip section extending from the rear side of the main body section, and the front end of the main body section is provided with a mounting interface. The operating component is mounted at the mounting interface of the housing and protrudes from the housing. A chip removal hole is formed in the bottom wall of the main body section of the housing, and a protective portion that extends downwards at least partially is provided at the bottom end at the position where the main body section joins the grip section. The bottom of a hand-held electric tool of the present invention is substantially closed, except for being provided with a chip removal hole, which allows removal of chips while preventing a user's hand from being inadvertently extended into the housing and contacting a component operating at a high speed. Moreover, chips removed through the chip removal hole are blocked by the protective portion, without reaching the grip section, which offers considerable advantages in terms of safety and hygiene.

A cleaning sheath for power tools, including a sheath assembly, wherein the sheath assembly includes a sheath, and wherein the sheath is rigid, the sheath is made of an impermeable material, and the sheath is hollow, a lid assembly located at one end of the sheath, a loop assembly located adjacent to the lid assembly, a cleaning solution located within a portion of the sheath, wherein the cleaning solution is adapted to clean and disinfect power tool blades located within the sheath, and an attaching assembly, wherein the attaching assembly includes an attaching element, and wherein the attaching element is removably attached to the sheath, and the attaching element is removably attached to predetermined surfaces.

The operating component is mounted at the mounting interface of the housing and protrudes from the housing. A chip removal hole is formed in the bottom wall of the main body section of the housing. The hand-held electric tool also includes a first rest block extending from a first side of the main body section and a second rest block extending from a second side of the main body section opposite the first side.

A method of constructing a cleaning sheath for power tools, including a sheath assembly, wherein the sheath assembly includes a sheath, and wherein the sheath is rigid, the sheath is made of an impermeable material, and the sheath is hollow, a lid assembly located at one end of the sheath, a loop assembly located adjacent to the lid assembly, a cleaning solution located within a portion of the sheath, wherein the cleaning solution is adapted to clean and disinfect power tool blades located within the sheath, and an attaching assembly, wherein the attaching assembly includes an attaching element, and wherein the attaching element is removably attached to the sheath, and the attaching element is removably attached to a structure.

According to examples, a power tool may include a chassis and a guide bar mounted to the chassis, the guide bar having a central axis. The power tool may also include a handle attached to the chassis above the central axis of the guide bar and a motor housed within the chassis to drive a chain around the guide bar, in which the motor is positioned beneath the central axis of the guide bar and a central axis of the motor is at a certain angle with respect to the central axis. The handle, the motor, and the battery pack mount may be positioned with respect to the chassis to cause the power tool to substantially be balanced in both lateral and longitudinal directions about a location near the trigger mechanism when the battery pack is mounted to the battery pack mount.

A handheld power tool, in particular a chain saw, includes (i) a hand protection lever, and (ii) at least one mechanical control unit for controlling the movement of the hand protection lever of the handheld power tool. The control unit includes at least one mechanical control element provided to control rotational movement of the hand protection lever by an axial relative movement between the control element and the hand protection lever.
