A ratcheting driver comprises a driving mechanism combined between a handle and a working end for translating rotary motion from the handle to the working end. A switch engages the driving mechanism to switch the rotational direction of the working end between clockwise rotation and counter-clockwise rotation with an optional locked position that locks the working end. Two pairs of cooperating pawls are provided that are selectively engaged by the switch with one pawl in each of the two pairs of cooperating pawls selectively engaging one of a first ratchet gear and a second ratchet gear. Each pawl in the pair of cooperating pawls are positioned axially apart from each other in alignment with one of the first ratchet gear and the second ratchet gear.

A ratcheting or non-ratcheting bit driver with a bit storage or “cartridge” that fits in the hollow portion of the driver handle. The bit storage or “cartridge” enables access to bits from both ends of all bits at a perpendicular orientation to the main axis of the handle while contained within the handle. The device remains in one piece rather than separating the assembly into two pieces, a handle and a cartridge during use.

A multi-function handle includes a connecting rod and a handle. The handle has an accommodation cavity therein. One end of the connecting rod is secured in the accommodation cavity from either of two ends of the handle, enabling the length of the connecting rod exposed out of the handle to be different. The present invention has a simple structure and an adjustable length, and is convenient for use.

A torque wrench is provided that includes a radio frequency identification (RFID) or near field communication (NFC) sensing mechanism that enables the wrench to receive information regarding the different attributes of a shaft that is operably connected to the wrench. The sensing mechanism can communicate with a corresponding RFID/NFC tag located in a shaft that is releasably connected to the wrench in order to receive information from the tag on the status of the shaft and set points for the application of torque using the shaft. Information can also be written and stored on the tag concerning the length of time the shaft has been in use.

A ratchet screwdriver with improved rotation efficiency includes: a grip; a driving assembly installed to a first assembly portion of the grip; a ring seat assembly installed to a second assembly portion and having a multiple of extension arms and a ring seat; a planetary gear set installed to a gear assembly portion of the ring seat; a rotary head installed to an end of the driving assembly and having a screwdriver assembly portion passing through a through-opening of the ring seat; a ring sleeve sheathed on an end of the driving assembly and having a ring-shaped gear installed to an inner side of the ring sleeve. Each extension arm can increase the arm of force of the ring seat assembly when linked and improve the rotation efficiency.

A driver with two operating positions has a handle with a first shell and a second shell connected that can open with respect to each other. Attached to one of the handle portions is a working end that is configured to rotate substantially, generally ninety degrees between a first position with a working end extending along an axis that is longitudinal with the handle and a second position with the working end extending along an axis that is transverse to the handle.
