A universal chisel attachment is an apparatus designed to convert the torque generated by an electric tool into a reciprocal linear motion to drive a chisel member. The apparatus includes a socket adapter, a chisel assembly, a hammering cam mechanism, and a tubular housing. The socket adapter enables the rotational connection of the hammering cam mechanism to a mounting mechanism of the electric tool. The socket adapter also enables the apparatus to be secured to the electric tool. The hammering cam mechanism converts the torque generated by the electric tool to a reciprocal linear motion of the chisel assembly. The chisel assembly enables the carving or cutting of the target object with the apparatus. The tubular housing enables the unobstructed operation of the hammering cam mechanism during operation. The tubular housing also safely retains all the moving components of the hammering cam mechanism to protect the user during operation.

Provided is a tool for mounting a seal in a groove or gap on a wind turbine, the tool including: a roller configured for rolling along the seal and in contact therewith, and a hammer unit configured for exerting a hammering action on the roller to push the seal or a portion thereof into the groove or gap as the roller rolls along the seal, wherein the tool includes a battery powering the hammer unit. Advantageously, the tool combines a rolling action with a hammering action to provide for easy mounting of the seal on the wind turbine.

An electrically driven orthopedic impactor may include an adapter for interfacing between the orthopedic impactor and a surgical implement. The adapter may have a first surface that transmits a forward impact energy and a second surface that transmits a reverse impact energy. The adapter can connect to the surgical implement and to the orthopedic impactor without the use of external tools. The adapter may connect to the orthopedic impactor via a pushing motion and may disconnect from the orthopedic impactor via a reciprocal sleeve. A sensor can communicate a spatial orientation of the adapter with respect to at least one reference point that is not located on the adapter or the orthopedic impactor. A communication device may transmit information to the orthopedic impactor related to frequency or impact energy settings based on a type of surgical implement attached to the adapter.

Provided is a battery pack which is miniaturized by reducing the number of components of a latch mechanism of the battery pack. In the battery pack comprising housings that accommodate a plurality of battery cells, and detachable latches, the latches have manipulation parts that are manipulated by an operator, springs that bias the manipulation parts to the outside of the housings, and first abutting parts on which ends of the springs abut. The manipulation parts move horizontally below the upper wall of the housing, and portions thereof are exposed to the outside from through holes formed in the housing. Furthermore, the latches are supported from below by any one among a separator holding the battery cell, a circuit board, and a lower case.

A tool for use with a hammer driver having a pin-accepting socket for driving a ground rod into the ground includes a body having two opposite side faces and at least one ground rod-accepting passageway extending between the two side faces. The tool also includes a guide pin which is joined to so as to extend from one of the side faces of the body and an elongated socket portion having first and second opposite ends and having a hollow interior which opens out of a first end of the socket portion. In addition, the socket portion is secured to the other side face of the body by way of the second end so that the first end extends away from the other side face of the body, and the guide pin and the elongated socket portion are axially-aligned with one another.

The present disclosure generally relates to quick change attachments for a pneumatic percussive tool. The attachments convert a pneumatic percussive tool, such as an air impact tool with proximal attachment means, which has a “pushing” force, into a pneumatic percussive tool having a “pulling” force. Once attached to the pneumatic percussive tool, the attachments also provide a quick change feature for allowing “pulling” tools to be simply and easily removed and replaced.

A power tool includes a motor, a housing, a battery holder and a cushion. The battery holder is held by the housing to be movable at least in a first direction relative to the housing. The battery holder is configured to removably receive a battery for supplying electric power to the motor. The cushion is held by the housing such that the first direction intersects the cushion. When the battery is attached to the battery holder, the cushion is directly or indirectly disposed between the battery and the housing.
