An improved multi-bolt and nut torque wrench for installing and removing bolts or nuts from flanged joints or the like which includes a plurality of torque stations having a plurality of high torque wrenches for engaging the heads of the bolts or nuts during a high torque phase of removal or installation; a plurality of low-torque motors operatively engaged with the wrenches for rotating the bolts or nuts during the low torque phase of removal or installation; a source of hydraulic fluid for driving the low-torque motors during the low-torque phase, and driving the high-torque wrenches during the high torque phase; and a mechanism for switching between the two phases depending on the torque needed.

A screwing/unscrewing tool for screwing/unscrewing a screw or a bolt includes a first part including a lever secured to a screwing/unscrewing bit provided with at least one screwing/unscrewing recess centered on a main axis, a second part including a support arm equipped with a tapped hole and on which the screwing/unscrewing bit is rotatably mounted around the main axis, and an adjustment screw screwed into the tapped hole and having a coupling head configured for a coupling with a screw-gun or a wrench, and extended by a threaded rod having a free end suitable for abutment on the lever in order to apply a pivoting force to it. The screwing/unscrewing tool may be used with a screw or bolt that is difficult to access in a crane mast or crane jib.

An apparatus providing a platform for installing screws can include a cart with wheels, an assembly rail system mounted to the cart, and a screw assembly mounted to the assembly rail system. The screw assembly can include a screw feeding device, a screw guide tube, and a screwing device such as a drill that rotates a drive shaft that engages a screw received from the screw guide tube. The screw feeding device can include a screw rack that holds screws, and a magnetic grip that moves a screw from the screw rack to a screw feeding tube that is connected to the screw guide tube. The screw guide tube can include bristles for centering a screw received from the screw feeding tube. The apparatus can include a computer control system that operates the screwing device and the screw feeding device.

The present invention relates to a vehicle's spare tire tool used for lowering down a spare tire stowed underneath of a vehicle, such as pick-up truck, SUV or any other off-road vehicle. The tool can also be used for stowing the tire back to the bottom of the vehicle. The tool kit features a 13″ tubular rod, that is designed to fit into a cordless drill, using an integrated male connector for rotating the rod. The rod also accommodates a connecting tip for hooking into a winch system of the vehicle. The rod with the attached connecting tip is inserted into an access hole at the rear of the vehicle and is rotated by the cordless drill. The tool kit enables users of all ages to easily dismount spares without overexertion or strain.

The present invention relates generally to the field of accessories for use with impact drivers that are useful for removing a valve seat from a fitting. The device has a first end, a second end and a central body portion. The first end has a shaft that allows the device to be attached to the chuck of an impact driver or drill. The second end has a head that can be placed within a valve seat. Once inserted into the valve seat, the impact driver or drill can be used to spin the device to remove the valve seat from the surrounding fixture.

Handheld device for manually actuating by a user, wherein the handheld device comprises a processing unit which is configured for processing an underground, and a sensor unit which is configured for detecting sensor data which are indicative for a condition of the underground before, during, and/or after processing the underground.

An inline ratcheting mechanism for motorized hand tools that includes a drive body, a ratchet shaft, ratchet pawls, a reversing collar, and a reversing switch adapted to cause the reversing collar to engage or disengage the ratchet pawls with ratchet teeth of the ratchet shaft.

A structure for replacing shear wrench head comprises a body having an inner sleeve portion, a ring groove is disposed around the inner sleeve portion and a first assembly portion is disposed on the inner sleeve portion; a chuck unit having a second assembly portion assembled with the first assembly portion; a central sleeve portion having at least one through hole with a locking member provided therein, a stop portion protruding inwardly is provided on the central sleeve portion, when the stop portion wedges with the first and second assembly portions, a position of the through hole approximately overlaps with the ring groove of the inner sleeve portion, so that the locking member can be disposed between the ring groove and the through hole; and an outer sleeve portion slidably disposed on the central sleeve portion, and capable of optionally restricting the locking member from moving outwardly.

A system for aiding the process of installing screw post earrings. The device is comprised of a portable, handheld, battery-operated, earring screw tool having the following parts: an interchangeable head that turns the decorative portion of an earring magnetically and a slotted head that turns an earring backing to secure an earring to the ear. The tool also has a sliding switch that allows the user to screw an earring on and off by turning the head forward or backward using only the finger tips. An object of the invention is to make the process of donning and doffing screw post earrings more manageable.
