Apparatus and method are disclosed for engaging a guide pin for installation or removal. The tool has a housing with a plunger positioned within the housing. A support tube has at least two extensions that protrude from the housing when an engagement mechanism is depressed and grips the guide pin when the engagement mechanism is released.

An apparatus, system and method comprising an improved wrench designed and configured for usage as a hand tool used to tighten or loosen a hexagonal bolt and/or nut is provided. More specifically, the present disclosure relates to an apparatus and method comprising an improved wrench configured to be used without any need to disengage and/or reengage the tool in order to execute its intended function. In addition, the present disclosure can also be categorized as a novel and improved ratcheting wrench having a series of pawls configured to slip past a gear in one direction and yet capture when rotated in the opposite direction.

A socket assembly for rotating a nut, the nut having an annular body with a radially inner edge defining a torque transferring surface, the socket assembly has: an intermediate socket extending axially relative to a central axis between a proximal end and a distal end, the proximal end of the intermediate socket engageable by a tool for rotating the intermediate socket about the central axis; and socket segments detachably connected to the intermediate socket in a circumferential array about the central axis, a socket segment of the socket segments having a nut-engaging end projecting radially outwardly relative to the distal end of the intermediate socket and engageable with the torque transferring surface of the nut to transfer a torque from the intermediate socket to the nut via the socket segments.

A tool head. The tool head includes an inner core and a plurality of nested shells fitted over the inner core. Each shell is engaged with the inner core at a proximal end. Each shell is independently biased towards the distal end of the inner core and independently compressible away from the distal end. Each shell is independently slidable relative to the inner core and relative to each other. A handle may be used to provide additional leverage and to fold over the tool head when the tool head is not in use.

A socket structure contains: a body, a fitting element, a first spring, a drive shaft, and a second spring. The body includes a first accommodation groove, a connection slot, a first trough, and a second trough. The fitting element includes a front section and a rear section, wherein the rear section of the fitting element has a notch, and the body includes at least one positioning element. The first spring is housed in the first trough and its first end abuts against the first trough and the second trough, and a second end of the first spring is biased against the rear section. The drive shaft includes a polygonal extension and a peripheral rib. A first end of the second spring abuts against the second trough, and a second end of the second spring pushes the polygonal extension to extend out of the second accommodation groove.

An impact socket includes a socket body having a first end and an opposing second end, the socket body defining a first fastener driving structure at the second end. The impact socket includes a collar assembly carried by the socket body, the collar assembly defining a second fastener driving structure. The collar assembly includes a support sleeve and a base sleeve that define a chamber configured to constrain movement of a securing mechanism relative to the socket body, the securing mechanism configured to selectively secure the collar assembly to the socket body when the collar assembly is disposed in at least one of a first position relative to the second end of socket body and a second position relative to the second end of socket body.

A socket assembly includes an outer socket and a first movable socket mounted in the outer socket. The outer socket is provided with a receiving chamber having a peripheral wall provided with a plurality of drive blocks and a plurality of retaining grooves. The first movable socket is movably mounted in the receiving chamber and includes a base and a plurality of driving pieces provided on the base. An elastic member is biased between the base and the outer socket. Each of the driving pieces has a first side provided with a restriction portion slidably mounted in one of the retaining grooves and a second side provided with a driving portion which has a pressing face.

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.

Disclosed are various embodiments for a universal aerator removal and installation tool, which may include a tool for rotationally engaging and turning an aerator coupled to a faucet spout. The tool may include a tool body having a first end and a second end and various keys positioned at the first end of the tool body. Each of the keys may include projections configured to rotationally engage and turn a different type of aerator. One or more aerator wrenches may be positioned at the second end of the tool body, where the aerator wrenches may project from the tool body and be configured to rotationally engage and turn different types of aerators.
