The working ball joint is inserted into the second receiving room and movable relative to the second receiving room to be in a first working position or a second working position.

A method and apparatus for installing or uninstalling supply lines or retaining nuts. A wrench includes a body having first and second sections rotatably coupled to each other. The body includes a first portion having a plurality of castellations, wherein a plurality of radial slots are formed between lateral surfaces of adjacent castellations, each radial slot being engageable to a wing of a retaining nut, wherein the first portion includes a plurality of first inner surfaces engageable to a first pipe fitting in the closed position. The body includes a second portion spaced away from the first portion, the second portion including a hinge for rotating the first and second sections relative to each other. The body includes a third portion located between the first and second portions, the third portion including a plurality of second inner surfaces engageable to a second pipe fitting in the closed position.

A light bulb remover extracts a broken light bulb from a socket of a high-hat light fixture. The light bulb remover has an extension pole and an extractor head attached to the extension pole. The extractor head has a guide which defines an outer circumference of the extractor head and a bulb extractor configured for engaging in a base of the broken light bulb and creating a friction connection with the base of the light bulb. The bulb extractor is surrounded by the guide, and the guide has a diameter being less than a diameter of the high-hat light fixture and dimensioned so that when the light bulb remover is disposed within the high-hat light fixture the bulb extractor is self-aligned with a middle area of the base of the broken light bulb.

A reciprocating pump includes a fluid end having a body defining a plunger bore that engages a plunger sleeve with a threaded interface, where the plunger sleeve defines throughbore configured to receive a plunger operatively reciprocating within the plunger bore during operation of the reciprocating pump. A packing assembly including a plurality of stacked annular seals is disposed between the plunger sleeve and the plunger. A packing nut having a threaded profile for engagement with a threaded surface of the plunger bore asserts a load against the packing assembly to ensure a positive engagement with the plunger.

The spindle area tube removal and installation tool includes an outer tube assembly; an inner tube assembly disposed within the outer tube assembly, the inner tube assembly having a first end and a second end; a handle assembly attached to the first end of inner tube assembly such that when the handle assembly is rotated the inner tube assembly rotates; a head assembly for gripping clamps within the spindle area; a gear assembly communicating with the head assembly, the gear assembly attached to the second end of the inner tube assembly such that when the inner tube assembly rotates the gear assembly provides a ninety degree power transfer to the head assembly, such that the head assembly rotates the clamps within the spindle area 360 degrees, allowing removal of the spindle area tube.

A method of preparing a shoulder to receive a glenoid component includes accessing a glenoid of a shoulder, positioning a distal portion and a proximal portion of a combination power extension/anti-rotation device on a guide wire positioned in the shoulder and reaming a hole in the shoulder using the combination power extension/anti-rotation device with the distal portion and the proximal portion positioned on the guide wire. The proximal portion is removed from the guide wire and pivoted with respect to the distal portion while the distal portion is still positioned on the guide wire. The picoted proximal portion is used to rotate an instrument to a first position and a bore is formed in the glenoid through the instrument with the instrument at the first position.

A ratchet wrench comprising a housing, at least one gear supported within the housing, one of the at least one gear comprising a drive hole, a stationary handle extending from the housing, a dynamic handle hingedly extending from the housing such that, the dynamic handle is rotatable between at least one handle open position and a handle closed position, and at least one pawl, each of the at least one pawl adapted to slide between a pawl open position and a pawl closed position, one of the at least one pawl adapted to be in engagement with one of the at least one gear at a time. The dynamic handle disposed in operative communication with the at least one pawl such that, rotating the dynamic handle towards the handle closed position causes the at least one gear rotate in one direction and releasing the dynamic handle causes pawl to return to the pawl open position without causing the at least one gear to rotate in the opposite direction.

A torque wrench assembly comprises a torque wrench and a reaction arm and locking means for locking together the torque wrench and the reaction arm. The locking means comprises a connection member located on the torque wrench; an opening on the reaction arm for receipt of the connection member of the torque wrench; a locking member slidably mounted in a channel on the reaction arm, the locking member including an aperture sized to allow the connection member to pass therethrough; and biasing means arranged to bias the locking member into a position wherein the aperture is partially aligned with the opening. The connection member has an insertion end for insertion into the opening of the reaction arm, and immediately adjacent the insertion end is a recess. The recess is shaped to receive a part of the locking member.

Various implementations include a surgical screwdriver that comprises a first rotating shaft configured to be rotated about a respective longitudinal axis, a second rotating shaft extending along a respective development axis transverse to the longitudinal axis of the first shaft and having a shaped end tip that can be inserted into the head of a screw, and a transmission member interposed between respective first ends of the shafts to transfer the rotation from the first shaft to the second shaft. The transmission member comprises a pair of hemispherical elements, hinged together about a respective junction axis that is perpendicular to the longitudinal axis of the first shaft, and each hemispherical element is in turn hinged to a first end of one of said shafts.
