A locking mechanism for use with a tool has a tool having a first working end, an opposite second end, a central axis therebetween, and a least one axial recess formed on an outer surface of the tool. A cap is rotatably received on the tool opposite second end, the cap comprising at least one recess formed on an outer surface thereon. The cap is rotatable between a first position in which the cap at least one recess aligns with the tool at least one recess, and a second position in which the cap at least one recess is out of alignment with the tool at least one recess. The locking mechanism further comprises a detent operatively positioned between the tool and the cap. The detent may be a pin and a spring, where the spring biases the cap into the second position.

A ancillary handle includes: a gripping part of the ancillary handle, a receiving part having an elongate seat for the shank, and a locking device for locking the shank and fixing the surgical instrument to the ancillary handle. A locking part engages in a groove on the outer surface of the shank. The locking part translates between: iii) a locking configuration, in which the locking part engages in the groove and blocks the surgical instrument, and iv) an unlocking configuration, in which the locking part frees the shank. The locking device includes an actuation part for moving the locking part between the locking and unlocking configurations.

A component part has an over-molded integrally formed insert member. The insert member has a predetermined feature. In addition, an end portion of the predetermined feature is exposed and free from over-molding.

A hand tool assembly generally comprising a handle and a tool head combined by a connector. The handle has a first end and a second end. The connector has a first end and a second end. The first end of the connector is combined with the second end of the handle. The second end of the connector is combined with the head of a tool by inserting the connector into a socket/opening in the tool's head. The second end of the connector is flexible thereby allowing it to conform to the shape of the socket regardless of whether the socket is straight or curved. A rigid tube insert is positioned a short distance into the handle second end and extends a short distance outward from the handle second end. Adhesives, fasteners, internal hooks, or other commonly known methods of securing an object within an outer sheath or covering may be used to help secure the components together.

A drain cleaning apparatus includes a handle and a clog-catching member detachably connected to the handle. Wings, barbs or hooks project radially from the clog-catching member. The wings, barbs or hooks provide an angled projection that catches and holds a clump of debris in a drain pipe for pulling the clump out and unclogging the drain. Different end tools can be removably connected to a clog-catching member or to a smooth extension member to provide multifunctionality. The handle, clog-catching members, smooth extension members and tools can be connected together using a quick-connect connector, such as a snap fastener, a keyhole fastener or a side-release buckle, or a threaded connector. In addition to drain cleaning, the apparatus can be fitted with tools such as a magnet, grabber, light, camera and/or video for retrieval of objects and inspection of a space that is difficult to view directly.

The invention relates to a torque wrench, which has a lever tube (3) having a handle (4) and has an indicating body (9) for indicating a set torque. The indicating body can be a scale housing or a scale sleeve. The handle (4) has a connecting piece (18), which points toward the indicating body (9) and which has a groove (19) on the outer periphery. Coupling segments directed toward the connecting piece (18) and having an abutment edge are provided on the indicating body (9). The handle (4) and the indicating body (9) are coupled by means of a locking ring (16). The locking ring (16) has blocking bodies for this purpose, which interact with the groove (19) on the connecting piece (18) and the abutment edges of the coupling segments in a locking manner. The torque wrench according to the invention is distinguished by the modular handle system thereof and enables economical production by means of structurally identical series together with simple assembly processes.
