The disclosure relates to a rechargeable battery pack for a hand-held power tool, having an interface for establishing an electrical connection of the rechargeable battery pack to a hand-held power tool and/or a charging device. The interface has contact elements for electrically contacting corresponding mating contact elements on the hand-held power tool and/or on the charging device. One contact element is a signal contact element which is electrically connected to an encoder element of the rechargeable battery pack. A rechargeable battery pack electronics is configured to provide information relating to the rechargeable battery pack via the signal contact element, said information relating to the rechargeable battery pack being stored, at least in part, in the at least one encoder element, wherein in the rechargeable battery pack electronics, the encoder element is connected, in an electric parallel circuit, in parallel with a dynamic current path.

A power tool includes a body, a power assembly, an output member, a clamping device, a battery pack, and a baseplate assembly. The power assembly is disposed in the body. The output member is driven by the power assembly to output power. The clamping device is connected to the output member and used for clamping a work attachment. The battery pack is connected to the body and supplies power to the power assembly. The baseplate assembly is connected to the body and includes a baseplate in contact with a workpiece. The battery pack includes a first support unit, the baseplate includes a second support unit, and the first support unit and the second support unit are disposed in the same support plane.

A gripping device includes a housing has an annular flange and a plurality of positioning recesses provided at the annular flange, a rear handle assembled with the annular flange of the housing, a push button pivoted to the rear handle and partially exposed to the outsides, a positioning block disposed in the rear handle, and a link rod having two ends pivoted to the push button and the positioning block, respectively. When the push button is unlocked, the positioning block is driven by the link rod to be disengaged from the positioning recesses, such that the rear handle is rotatable to adjust angle. When the push button is locked, the positioning block is engaged with one of the positioning recesses under the force of an elastic member for positioning the rear handle.

Therefore, a user can operate the gripping device at an ergonomic angle.

A power tool includes a casing, a cutting unit, a transmission device, and a toggle switch. The casing includes a support portion. The cutting unit is used for cutting a target object and moving between a first position and a second position relative to the support portion. The toggle switch includes at least a third position and a fourth position. When the toggle switch is at the third position, the cutting unit performs a first motion: the cutting unit moves from the second position to the first position. When the toggle switch is at the fourth position, the cutting unit performs a second motion: the cutting unit moves from the first position to the second position. A speed at which the cutting unit performs the second motion is greater than a speed at which the cutting unit performs the first motion.

Provided is an electric device capable of suppressing vibration of a battery pack. Included are: a first housing 21 accommodating a load portion that consumes electric power; a second housing 22 having one end portion connected to the first housing 21 and another end portion to which a battery pack 9 is connectable; and an elastic member 40 interposed between the first housing and the second housing. The first housing includes a first restricting portion 42 positioned away from the elastic member, and the second housing includes a second restricting portion 44 positioned away from the elastic member and engageable with the first restricting portion. In a case where the second housing is urged to be separated from the first housing, the elastic member is deformed and the first restricting portion and the second restricting portion are engaged with each other to prevent separation.
