A socket tool is disclosed. The socket tool includes a body extending between a first end and a second end and having a centerline along a longitudinal axis of the socket tool; a socket bounded by a peripheral wall and formed at the first end, the socket including a first driving element extending through the peripheral wall, bisecting the peripheral wall into first and second wall sections; and a drive recess at the second end of the body to receive a nose of a driving tool.

A ratchet keychain attachment includes a body and a ratcheting area in the body. The ratchet keychain attachment further includes a bit holder, the bit holder pivotally mounted in the body. The ratchet keychain attachment further includes a bit, removably located in the bit holder, the bit holder having a first position where the bit is held in a non-removable position in the bit holder and a second position where the bit is in a removable position.

A wrench includes a ratchet unit located in the head and includes a mount hole. A collar is connected to the head and includes a slot and an aperture. A C-shaped engaging member includes a first end thereof inserted into the aperture. A second end of the engaging member protrudes beyond the collar. The engaging member includes a second section which is a curved section and resiliently protruded into the slot. A rotary member is mounted to outer periphery of the collar and includes a notch defined in the underside thereof. The second end of the engaging member is located in the notch and covered by the rotary member. When the rotary member is rotated, the engaging member is deformed to insert or remove the second section relative to the mount hole via the slot to position a socket in the head of the wrench.

A flip socket is disclosed. The flip socket including a socket body having a central section extending between a first socket positioned on a first end of the central section and a second socket positioned on a second end of the central section, wherein a centerline extends through a longitudinal axis of the socket body; and a coupler adapted to engage one of the first and second sockets, the coupler connecting the flip socket to a driving device to drive a fastener or device.

The invention provides a dual-purpose handle, comprising a body, wherein mounting holes are provided in the body and are used for connecting to functional members; the mounting holes are provided in the body in both an axial direction and a radial direction; axial and radial mounting holes provided in the body can enable the handle and the functional members to easily and quickly switch between two connection forms, i.e. straight and T-shaped; and torsional torques that are different in magnitude can be output by means of different connection manners under the action of the same operation force. Clamping devices fitted with the functional members are arranged in the mounting holes; and when the functional members are connected to the handle, the clamping devices can fix the functional members and prevent same from rotating in a cavity of the body of the handle. The axial and radial holes of the handle are configured to be through holes, so that the handle can be adapted to guide needles of different sizes passing through same and is suitable for minimally invasive surgery, thereby further expanding the range of use of the handle.

A bicycle tool according to the disclosure comprises a valve connection means. A tool element is connected with the valve connection means. The tool element is connected with the valve connection means in its longitudinal direction such that an elongated bicycle tool is formed.

A pair of screwdrivers each having a handle, a nondetachable outer shaft, a detachable inner shaft, and at least two detachable double-ended screwdriver bits. Each screwdriver handle is formed having a hollow space configured to substantially house the outer screwdriver shaft, the inner screwdriver shaft, and the at least two double-ended screwdriver bits of the other screwdriver, whereby, the pair of screwdrivers may be assembled together when not in use so that the outer shaft, the inner shaft, and the at least two double-ended screwdriver bits of both screwdrivers are substantially non-exposed to prevent the potential for accidental user injury.

A socket includes a socket body, a teeth structure, and a stopping structure and is engageable with a tool member. The socket body has an opening and an inner wall. The teeth structure is disposed on, and along the circumference of, the inner wall of the socket body and includes alternating inner teeth and concave portions. The stopping structure is disposed on, and along the circumference of, the inner wall of the socket body, is farther away from the opening than is the teeth structure, and includes a through hole and an inner surrounding wall. The through hole corresponds to the opening and is surrounded by the inner surrounding wall, which has a thickness. The distance from each concave portion to the hole wall surface of the through hole is defined as a stopping distance to be considered in relation to the thickness of the inner surrounding wall.

A socket includes a socket body, a detent rod, and a pushing element. The socket body includes an opening, a teeth structure disposed on, and along the circumference of, the inner wall of the socket body, and an abutting structure farther away from the opening than is the teeth structure and including a first and a second through hole. The first through hole penetrates two sides of the abutting structure and is perpendicular to the axial direction of the socket body. The second through hole is at the center of the abutting structure and communicates with the first through hole. The detent rod is movably disposed through the first through hole and has a diminishing portion that tapers from two ends of the detent rod toward the center. The pushing element is movably disposed through the second through hole and has one end abutting against the diminishing portion.

The present disclosure relates to a powered screwdriver. The powered screwdriver includes a housing, a motor housed in the housing and a tool holder driven by the motor. The tool holder selectively holds both a screwdriver bit and a hex key. The hex key includes a bend such that legs of the hex key are transverse to one another.
