Power tool

An electric power tool includes a tool unit and a battery pack. The tool unit includes a pair of conjunct grooves and two corresponding blocks. The battery pack includes a pair of conjunct rails and two locking members. The tool unit and the battery pack are connected and locked with each other respectively by that the conjunct grooves and the conjunct rails are interconnected with each other and the two locking members and the two blocks are jammed together. In addition, the tool unit and the battery pack can be dimensionally reduced and the cohesive effect therebetween can be strengthened respectively by the conjunct grooves and the conjunct rails.

Electric power tool

A power tool includes a housing, a fixed ratchet seat, a drive spindle, a rotatable ratchet, and an operating knob. The ratchet seat is disposed immovably in the housing. The drive spindle extends rotatably through the ratchet seat and is axially movable between front and rear limit positions. The rotatable ratchet is mounted on the drive spindle for co-rotation therewith, and disengages the fixed ratchet seat when the drive spindle is at the front limit position, and engages the fixed ratchet seat when the drive spindle is at the rear limit position. The operating knob is sleeved rotatably on the housing, and is rotatable to drive rotation of a switching ring in the housing. The switching ring is associated operably with a latching seat on the drive spindle to enable and disable movement of the drive spindle between the front and rear limit positions.

Power tool having an operating knob for controlling operation in one of rotary drive and hammering modes

A power tool includes a function control mechanism to control operation of a drive spindle in a selected one of a rotary drive mode and a hammering mode. The function control mechanism includes a first ratchet that is mounted to rotate with the drive spindle, a second ratchet that is slidable from a first position to a second position, and a ring controller. The second ratchet is disengaged from the first ratchet when the second ratchet is in the first position, and is engaged with the first ratchet when the second ratchet is in the second position. The ring controller is coupled to a push ring that abuts against the second ratchet such that rotation of the ring controller results in movement of the second ratchet between the first and second positions.
