An adaptor head mountable in a drill chuck, the chuck adaptor head having interchangeable tool bits for efficiently performing drill and drive operations that require an assortment of bits. A quick change of bits is realized by mounting each bit in a pivotable yoke cradle that guides the bit from a “head-up detent position” to an “head-down” active position” when needed, eliminating the need for chucking and unchucking of bits. In a first embodiment, the chuck adaptor head is configured to mount four or more bits on yoke cradle members for rapid, uninterrupted use by rotating the bits in and out of a driver socket at the end of a rotating spindle.

A multipurpose hand tool may include a body portion, and a first hex socket tool integrally formed with a first side of the body portion. The multipurpose hand tool may include a second hex socket tool integrally formed with a second side of the body portion that opposes the first side of the body portion, and a screwdriver tool integrally formed with a third side of the body portion. The multipurpose hand tool may include a wrench tool integrally formed with a fourth side of the body portion that opposes the third side of the body portion.

A boat motor propeller wrench with metallic motor nut fastener is described. The wrench includes a polymer handle including a first end and a second end opposite the first end, the second end including a tethering aperture. The wrench also includes a socket formed as one piece with the handle and extending from the first end of the handle substantially perpendicular thereto, the socket defining an aperture. The wrench further includes a metallic insert disposed within the aperture of the socket.

An impact tool includes a housing, a motor supported within the housing, an anvil extending from the housing, and a drive assembly configured to convert a continuous rotational input from the motor to intermittent applications of torque to the anvil. The anvil includes a body rotatable about a longitudinal axis, a driving end portion configured to receive a tool element over a distal end thereof, and a bore extending through the driving end portion of the anvil in a direction transverse to the longitudinal axis. The driving end portion includes a groove located between the bore and the distal end. The groove includes a curved portion converging toward the distal end and is configured to receive a friction ring such that the friction ring follows a contour of the groove.

A ratchet screwdriver includes a direction-switching apparatus. The direction-switching apparatus includes a cylinder, a toothed wheel, two pawls, two springs and a connector. The cylinder includes a wheel-containing chamber in communication with two pawl-containing chambers. The toothed wheel is inserted in the wheel-containing chamber. The pawls are respectively inserted in the pawl-containing chambers. Each of the springs is connected to one of the pawls in one of the pawl-containing chambers. The connector interconnects the springs so that at least one of the springs keeps at least one of the pawls engaged with the toothed wheel to allow the cylinder to rotate the toothed wheel in at least one of two directions.

A ratchet screwdriver includes a direction-switching apparatus. The direction-switching apparatus includes a cylinder, a shaft, a toothed wheel, two pawls, at least one spring and a bushing. The shaft is inserted in the cylinder. The toothed wheel is formed on the shaft. The pawls are inserted in the cylinder. The spring interconnects the pawls to keep at least one of the pawls engaged with the toothed wheel to allow the cylinder to rotate the toothed wheel in at least one of two directions. The bushing is inserted in the cylinder to support the shaft.

A multi-tool includes a pair of plates having respective handle portions, joint portions, and head portions, with the plates pivotally connected to each other at the joint portions, and to be pivoted relative to each other to establish an open position and a closed position of the plates. A bit holder is extended from an end of one of the plates, with the bit holder including a socket to receive an insert bit, the handle portion of the one of the plates including a storage area to receive and store the insert bit, and, in the closed position of the plates, the plates to overlap each other with the handle portion of the other of the plates to cover the storage area and the handle portion of the one of the plates.

The disclosure relates to a bit holder 1 for holding and driving a screw 3 with a screw head 4 into a fastening base, comprising a clamping region 2 for connecting the bit holder 1 to a driving tool and a bit receptacle 16 for inserting a bit suitable for driving the screw 3. The bit holder 1 has at least one magnet 7a-7f, 7.1a-7.1f arranged eccentrically relative to the bit holder 16 with one pole facing the screw head 4, wherein the magnet 7a-7f, 7.1a-7.1f is held floating on a magnet holder 8, 8.1 in relation to a bit 6 held in the bit receptacle 16, so that the pole face of the at least one magnet 7a-7f, 7.1a-7.1f can align according to the contour of the screw head 4 in order to hold the screw 3 on the bit holder 1 in such a way that the bit 6 engages torque-locked in a rotary driver contour 5 of the screw head 4.

A length adjustable connection structure contains: an adjustment assembly, an engagement assembly, and a receiving tube. The receiving tube includes an insertion accommodated, a coupling portion, a groove, a trench, and an elongated slot. The engagement assembly includes a fixing portion, a toothed portion, a fitting portion, a hexagonal hole, and a circular hole. The adjustment assembly includes a connector, a locating orifice, a hexagonal column, and a C-retainer. The hexagonal column of the adjustment assembly is received in the hexagonal hole of the engagement assembly so that the engagement assembly is connected on the hexagonal column, the C-retainer is engaged in the notch of the hexagonal column, and the adjustment assembly and the engagement assembly are accommodated in the receiving tube, hence the toothed portion of the fixing portion is engaged in the groove of the coupling portion, and the fitting portion is fixed in the trench.

Exemplary embodiments are disclosed of socket adaptors for retaining impact sockets to impact tools.
