The drive unit includes a body, a recessed portion having a defining fringe, a screw bolt, and a chamber. An air discharge conduit is defined between the slidable sleeve and the body. The first segment has a second coupling orifice. The resilient element includes a through hole. The first isolation ring includes a first rim, a second rim, multiple first discharging grooves, and multiple first contact portions. The second isolation ring includes a third rim, a fourth rim, multiple second discharging grooves, and multiple second contact portions.

There is provided a driving machine capable of reducing a load applied to a guide member in a direction of a center axis. The driving machine drives a fastener into a workpiece. The driving machine includes a movable piston, a driver blade operating together with the piston and applying driving force to the fastener, a cylinder guiding operation of the piston, a holder provided in a housing and supporting the cylinder, and a vibration damping rubber interposed between the holder and the housing and receiving a load applied to the holder in an operational direction of the piston.

Provided are an electric handle, an electric toothbrush and an electric cleaning brush. The electric handle comprises a housing, a rear cover, a swing motor and a main control structure. By installing a vibration control mass with limited mass, the rotational inertia of the stator of the swing motor is increased, so that the vibration amplitude of the shell of the swing motor is reduced. It also reduces the vibration amplitude transmitted to the control circuit board, battery and electric handle, decreases the vibration feeling in user's hand, and makes the output shaft of the swing motor transmit effective swing output as much as possible. Then the swing output is transmitted to the toothbrush head or cleaning brush head installed on the output shaft. In this way, the cleaning effect and vibration reduction effect are better, the hand feeling is more comfortable, and the production cost is also reduced.

A power tool includes a housing, a motor positioned substantially within the housing, a drive mechanism supported by the housing and coupled to the motor, a battery pack electrically coupled to the motor, and an isolation system. The isolation system includes an interface member positioned substantially within the housing. The interface member receives a portion of the battery pack to electrically couple the battery pack to the motor. The isolation system also includes a plurality of isolators coupled between the housing and the interface member to isolate the battery pack from the housing during operation of the power tool.

The shock absorbing device includes at least one shock absorbing element for absorbing shock energy exerted on the housing of the rechargeable battery.

An impact wrench for tightening and loosening nuts and screws on a track has a vibration decoupling device which serves for vibration decoupling of at least one handle from an electrically operated impact screwing mechanism.

A hand-held power tool, in particular a saber saw, having at least one holding unit for fastening the hand-held power tool to a holding device, in particular to an arresting cable and/or carabiner clip. The holding unit includes at least one receiving opening for receiving the holding device, and at least one damping element for damping a force transferred from the holding device to the hand-held power tool, in particular to a housing of the hand-held power tool. The damping element includes an at least substantially elastic element that at least partially encloses the receiving opening and receives in a form-fitting manner a fastening part delimiting the receiving opening.

A power tool may include a compartment in its housing and a first printed circuit board (PCB) located in the housing and electrically coupled to a first connector. An insertable wireless communication device may include a second electronic processor and an antenna that are each mounted to a second PCB. The insertable wireless communication device may be configured to be received in the compartment and may include a second connector configured to electrically and physically couple to the first connector. The insertable wireless communication device may be configured to wirelessly communicate with an external device. When the insertable wireless communication device is inserted into the compartment, a first conductive layer of the first PCB may be configured to be electrically coupled to the antenna via the first connector and the second connector such that the first conductive layer of the first PCB serves as a ground plane of the antenna.
