The present invention relates to a three-piece wrench comprising: a wrench body with a working head and a shaft, the working head is located at a front end of the shaft, the shaft has a length; a first extension rod with a length; and a second extension rod with a length; the lengths of the first extension rod and the second extension rod are greater than the length of the shaft; combination of the wrench body, the first extension rod and the second extension rod provides various usage lengths of the wrench, so that different connection types can be used to form required lengths according to requirements.

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.

A wrench and a method for manufacturing the same are provided. The wrench includes a main body and a covering member. The main body includes a head portion and a handle. The head portion has a receiving groove. The covering member covers the receiving groove. One of the main body and the covering member has a first washer and a second washer integrally disposed thereon. The first washer and the second washer are abutted against and between the main body and the covering member. Therefore, shapes of the first washer and the second washer are designable and can be directly formed on any position of the wrench.

A fastener removal apparatus is configured for removing a nut from a threaded shank and includes a gearbox assembly, an outer socket, and a tubular sleeve member. The gearbox assembly has an input member, a first output member, a second output member, and a plurality of gears. The first output member and the second output member rotation in opposite directions about a longitudinal axis in response to rotation imparted to the input member. The outer socket extends between a first end defining a female polygonal opening and a second end engaged for concurrent rotation with the first output member. The tubular sleeve member extends between a first end defining a threaded opening for receiving threads defined by the threaded shank and a second end engaged for concurrent rotation with the second output member.

Torque adapter for a cable connector that expands to fit connector nuts of different sizes. The adapter fits around the cable connector and engages three of the corners of a hex nut with matching recessed regions in its inner surface. It has three slots that receive the other three corners of the connector nut. The adapter is flexible so that the slots may widen to accommodate connector nuts of larger widths. The outer surface may be hexagonal so that a wrench or similar tool may be used to turn the torque adapter.

A socket assembly includes an outer socket, an inner socket mounted in the outer socket, and an intermediate socket mounted in the outer socket. The outer socket has a plurality of drive blocks and a plurality of retaining grooves. The inner socket includes a first base, a plurality of first driving sections, and a plurality of first openings. The intermediate socket includes a second base, a plurality of second driving sections, and a plurality of second openings. Thus, the inner diameter defined between the first driving sections is smaller than that defined between the second driving sections by 2 mm, and the inner diameter defined between the second driving sections is smaller than that defined between the drive blocks by 2 mm, so that the inner socket, the intermediate socket and the outer socket co-operate to operate three successive sizes of nuts.

A universal tool which can be a screwdriver, wrench, pliers, or any other tool. The tool can operate on an object (e.g., a screw, bolt, etc.) of any shape because of a set of pins that can mold to match a shape of the object. For example, a same universal screwdriver has pegs which mold themselves to match a shape of a slotted screw head or mold themselves to match a shape of a philips screw head. A user of the universal screwdriver can then turn such screw by turning the universal screwdriver in a standard fashion. When the universal screwdriver is removed from the object, then the pegs automatically revert themselves to a default position so a different shaped screw head can then be operated on.

A socket includes a first and a second sleeve members. The first sleeve member has a first end for connecting to a driving tool and a second end having a first connecting portion for sleeving onto a first fastener, and has an internal space and an internal circumferential wall. The second sleeve member is movably inserted into the internal space and has an external circumferential wall and a second connecting portion connected together. The second connecting portion is for sleeving onto a second fastener whose size is different from a size of the first fastener. One of the external and the internal circumferential walls is tapered from the first end toward the second end to form a gap. The other one of the external and the internal circumferential walls has a restriction unit extending into the gap.
