A ratchet wrench capable of rotating quickly and driving rotation includes a handle, a rotary head, a positioning mechanism, and a sleeve. The handle includes an arm and a bar body. The bar body includes an accommodating slot; the arm includes a through hole. The rotary head is connected to the arm and includes recess portions. The positioning mechanism includes a positioning element, a resilient body, and a block element. The resilient body receives the positioning element and is received in the through hole, the positioning element is correspondingly disposed in any of the recess portions, and the block element is connected to the positioning element. The sleeve receives the bar body and operably drives the block element to slide in the accommodating slot, so that the positioning element is positioned and selectively engaged with any recess portion.

An example embodiment of the present invention is a wrench handle that is elongated in a predetermined direction. At least a portion of the wrench handle is hollow. The hollow portion has a front part and a rear part. The hollow portion is also configured to substantially house and detachably secure a socket extension bar therein.

A tool fitting attachment for a surgical drill can include a drive-side coupling for mounting on a drive unit which provides a torque via a motor, and an output-side coupling for receiving a tool. A drive unit is integrated between the two couplings and can be manually operated. A surgical drill can include an electric motor which is connected via the drive-side coupling of the tool fitting attachment.

A wrench assembly capable of being rotated quickly is adapted for rotating a fastener. The wrench assembly includes a wrench and an inserting member. The wrench includes an acting head and a handle. The acting head is adapted to be combined with the fastener. The handle is connected with the acting head and extends along a horizontal direction. The handle is provided at an end thereof far away from the acting head with an inserted hole portion. The inserting member is detachably inserted in the inserted hole portion along a vertical direction.

An electric quick action wrench with settable torque, which is operated in an electric mode or a manual mode, includes: a main body, a controller, a motor, a driving device, and a clutch device. The driving device is driven by the motor and combined with a fastener. The controller sets a threshold torque value. In the electric mode, when the fastener confronts a resistance larger than a clutch torque of the clutch device, the user is notified to switch to the manual mode through the notification of the clutch device. In the manual mode, when a manually output torque reaches the threshold torque value, the user is notified that the screwing operation has been finished by the notification of the clutch device. Thus, the safety of usage is achieved.

A foldable handle includes a connection section and a grip section. A recess is defined in the connection section and a function part is located in the recess. A restriction unit extends through the connection section to pivotably connect the function part to the connection section. The restriction unit is operated to restrict the function part to be co-axial with the handle, or to restrict the function part to be an angle relative to the handle. The function part includes a neck received in the recess so as to make the foldable handle be compact for convenience of storage.

A ratchet wrench (1) has a flexible clutch ring (500) that forms the mid part of a laminate-like structure comprising a wrench head (200), the clutch ring (500) and a drive element (40). When under load, the compression forces applied to the clutch ring (500) are substantially dissipated around its circumference (508) and inner surface (509), this inward force clamping upon the inherently strong drive outer surface (45). The laminate-like construction enables a reduction in the width or depth of the wrench head without a loss in strength.

A torque limiting ratcheting handle for a medical instrument is provided that includes a ratchet shifter, a tool connector, a torque coupler, and a rear power housing. The handle provides clockwise and counterclockwise ratcheting and limits the amount of torque in one direction while allowing for maximal torque in the opposite direction. In one aspect, the ratcheting handle may include a drive shaft removeably connected to a power tool or, alternatively, to a handle grip for manual manipulation.

A universal ratcheting tool provides improved handling of tools that are difficult to use on their own, specifically, hexagonal wrenches. The universal ratcheting tool includes a handle and a body with a ratcheting mechanism within the handle. The body includes a first aperture for receiving a tool, and the first aperture includes slots to accept a plurality of sizes of tools. The body also includes a second aperture where the tool extends out of the body. A retaining component is coupled with the body to retain the tool and a retaining tab is able to be used to open and close the retaining component. Once the tool is positioned and retained within the universal ratcheting tool, a user is able to easily install or remove an object such as a screw with the benefit of a comfortable handle and the ease of use of the ratcheting mechanism.
