Abstract: A power tool including a housing having a handle configured to be grasped by a user, a motor supported by the housing, a driving gear rotated by the motor, and a driven gear engaging the driving gear to be rotated by the driving gear about a rotation axis. The power tool also includes a pin extending from the driven gear and offset from the rotation axis and a spindle having a yoke coupled to the pin to translate rotation of the driven gear into reciprocating motion of the spindle. A notch is formed in an outer periphery of the yoke to provide clearance for the driving gear as the spindle is driven by the pin.

Abstract: An assembly of saw handle and saw member is provided. An end portion of the saw member is inserted into an inserting groove of the saw handle. The saw handle has stopping bars at an inserting portion and a swing arm. The end portion defines an opened hole and a closed hole. When the swing arm is moved to an eject position and not received in a receiving space of a guard portion of the saw handle, the saw member is not blocked by the swing arm and is allowed to be inserted into the inserting groove. After the saw member is inserted into the inserting groove and the swing arm is moved to a fix position, the stopping bars are respectively located in the opened hole and the closed hole, so that the saw member can be assembled with the saw handle in a convenient and rapid manner.

Abstract: A pole saw includes a long handle with cast end adapter, a cast saw-holding component pivoted to the end adapter for movement between an extended use position and a handle-adjacent storage position, and a saw blade pivoted to the holding component for movement between a blade-use position and a blade-protected position. The end adapter and holding component are cast aluminum for strength and light weight, and are pivoted together about an offset axis so that the blade and blade-holding component are positioned adjacent the handle in a partially protected position that is very compact; thus, no disassembly or separate tools are required. A folding lock mechanism includes a hook and pressure pad that cooperate for secure locking in the extended use position. An adjustable set screw eliminates blade looseness when in the use position.

Abstract: A hand saw including an ergonomically constructed saw blade holder with a pistol type grip, an elongated support having a blade channel for receiving and supporting a particular “T” blade, and various tooth configurations of a saw blade having a cooperating T-shaped blade shanks. Each blade shank includes an aperture at its rear end for receiving a locking pin positioned at the back end of the blade holder that drops into position to secure the blade within the channel of the grip. Additionally, a trigger-like mechanism on the pistol grip, when squeezed, rotates a rubber surfaced pad upward through an opening in the base of the support to contact the underside of the blade shank pushing it upward into the top of the channel to insure blade stability. The “T” design of the blade allows orienting the cutting surface of the blades in different directions so that a user does not have to twist their body or arm to saw.

Abstract: A portable, hand-operated trimmer has a head module that is removably connected to a power control module. The head module has a power head enclosing an electric motor that is operatively connected to a trimming blade. The power head is selectably settable in a plurality of angular positions with respect to a head support, including a neutral position representing 0 degree rotation, 45 degree flexion and dorsiflexion positions, and 90 degree flexion and dorsiflexion positions. The power head also encloses a stator cartridge that is connected to the housing of the power head by a plurality of fastening members. The head support rotates about the stator cartridge and is engaged by way of a movable engagement pin that is received within a selected recess defined in the stator cartridge. The power head housing and stator cartridge further define molded sockets to receive corresponding pivot arms of the head support. An O-ring is disposed about one of the pivot arms to dampen free rotation. The power control module provides power to the power head through a removable rechargeable battery or through direct connection to conventional household power.

Abstract: A hand saw includes a saw blade, a handle, and a blade carrier. The saw further includes a blade clamp assembly having a locking member that removably couples the saw blade to the blade carrier so that the saw blade pivots with the blade carrier about a pivot axis. An actuating button is manually movable generally transverse to a longitudinal axis of the saw blade by the user between an engaged position and a disengaged position. In the engaged position, the actuating button engages the blade carrier to retain the blade carrier and the saw blade in one of an extended position and a folded position. In the disengaged position, the actuating button is disengaged from the blade carrier so that the blade carrier and the saw blade can be pivoted between the extended and the folded positions of the saw blade.
