An adaptor head mountable in a drill chuck, the chuck adaptor head having interchangeable tool bits for efficiently performing drill and drive operations that require an assortment of bits. A quick change of bits is realized by mounting each bit in a pivotable yoke cradle that guides the bit from a “head-up detent position” to an “head-down” active position” when needed, eliminating the need for chucking and unchucking of bits. In a first embodiment, the chuck adaptor head is configured to mount four or more bits on yoke cradle members for rapid, uninterrupted use by rotating the bits in and out of a driver socket at the end of a rotating spindle.

A power tool includes an output assembly and a battery pack. The output assembly is disposed at an end portion of a first handle, the output assembly includes at least two output units spaced apart and used for connecting working accessories, and the output assembly is rotatable about a shift axis to shift an output unit among the at least two output units to a working position or a non-working position. The battery pack is disposed at a bottom of a body, the battery pack includes a standing surface through which the power tool is capable of standing, and when the power tool stands, a projection of a center of gravity of the power tool on the standing surface is in the standing surface.

A nut runner accessory for a power-driven tool is provided. The nut runner accessory can include a gear assembly received in a housing. The gear assembly transfers an externally generated force to a driver head of the nut runner accessory. The driver head can include a plurality of stepped pockets that can receive and engage different sizes and/or configurations of nuts to be threaded onto/off of a threaded rod. The driver head can be counterweighted, to counteract imbalance generated due to an offset between a center of mass of the driver head and a center of rotation of the driver head.

A power tool is arranged to operate in at least a first operating mode and a second operating mode. The power tool is operative to provide a first type of light signal from a light emitting device arranged to light up an object to be processed when the power tool is set in the first operating mode and to provide a second type of light signal when the power tool is set in the second operating mode.

A surgical device includes an adapter assembly that selectively interconnects a loading unit and a device housing. The adapter assembly includes a drive converter assembly for interconnecting a rotatable drive shaft and an axially translatable drive member of the loading unit. The drive converter assembly converts and transmits a rotation of the rotatable drive shaft to an axial translation of the axially translatable drive member of the loading unit. The drive converter assembly includes a drive element, a drive nut, and a distal drive member. The drive element defines a longitudinal axis. The drive nut is disposed about the longitudinal axis, and the distal drive member is disposed along the longitudinal axis.

A working head for a hydraulic power tool including a head frame and a first moveable die head configured to move along the working head frame. The first moveable die head configured to receive a first moveable die comprising a first body length. A second die head is adapted to receive a second die comprising a second body length. The first body length of the moveable die is different from the second body length of the stationary die.
