摘要： A handle assembly for a power tool is disclosed. The handle assembly includes a base adapted to be mounted to a body of a power tool, and a handle having first and second mounting portions pivotably mounted to respective ends of the base. An elongate torsion spring has a first part mounted to the base and a respective second part mounted to each mounting portion such that pivoting of the handle relative to the base member causes twisting of the torsion member to resiliently oppose pivoting of the handle relative to the base portion.

摘要： A mounting apparatus for mounting a handle to a power tool is disclosed. The apparatus comprises a base for supporting a handle and engaging a body of the power tool, a flexible strap for engaging the base at first and second locations to form a loop for retaining the support in engagement with the body of the power tool, and a clamping mechanism comprising a pair of wedges for engaging the base and the flexible strap, and a bolt for retaining the wedges in position relative to the base. A knob enables movement of the wedges relative to each other in a first direction to reduce the size of the loop and in a second direction to increase the size of the loop.

摘要： A powered hammer includes a housing, a tool holder coupled to the housing and configured to hold a tool, a motor within the housing, a cylinder disposed within the housing, and a piston slideably mounted within the cylinder. A drive mechanism converts rotary output of the motor into a reciprocating motion of the piston. The drive mechanism includes a crank shaft rotationally driven by the motor, a drive pin eccentrically mounted on the crank shaft, and a con rod with a first end connected to the drive pin and a second end connected to the piston. A ram is slideably mounted forward of the piston that is reciprocatingly driven by the piston. A beat piece is slideably mounted forward of the ram. The beat piece is repetitively struck by the reciprocating ram, which in turn repetitively strikes an end of the tool when held in the tool holder to transfer the momentum of the ram to the tool. Lubrication fluid covers at least part of the drive mechanism. A rear piston chamber is formed within an end of the cylinder, rearward of the piston, the volume of which repetitively changes as the piston moves within the cylinder, causing air within the housing to be at least one of drawn into and blown out of the rear piston chamber. The movement of air causes the lubrication fluid to move within the housing. A longitudinal passageway defined in at least one of the crank shaft and the drive pin enables passage of air and the lubricating fluid to assist in movement of the lubrication fluid within the housing.

摘要： A motorized hammer has a body and a tool holder which is mounted on the front of the body and is capable of imparting impacts via the tool in the holder. A rear handle is, moveably mounted to the rear of the body via at least one movement control mechanism which is capable of moving towards or away from the body. A biasing mechanism biases the rear handle away from the body and each movement control mechanism includes a first mount. A rod having a longitudinal axis is rigidly connected at one of it ends to the first mount. A second mount slidingly engages with the rod at two distinct points only along its length to allow the rod to slide relative to the second mount in a direction parallel to the longitudinal axis. The second mount prevents the rod from moving in a direction perpendicular to the longitudinal axis.
