Abstract: A telescopic tool includes a positioning device mounted between first and second rods. The first rod includes a first positioning hole, and a first gripping portion. The second rod includes a plurality of second positioning holes, and is movable relative to the first rod to align the first positioning hole with one of the second positioning holes. A switch controller is movable relative to the first rod and is movably coupled to a positioning member. The positioning member movably extends through the first positioning hole and is releasably engaged in one of the second positioning holes in response to movement of the switch controller relative to the first rod. A fixing member includes a second gripping portion mounted around the first rod. A resilient biasing member is pivotally connected to the first rod and pressing against the positioning member.
Abstract: Circlip pliers comprise a first plier and a second plier. The first plier is provided with an external connection portion, an internal connection portion, and a pivot portion located between the external connection portion and the internal connection portion. The second plier is provided with an external connection portion, an internal connection portion, and a second pivot portion located between the second external connection portion and the second internal connection portion. The external connection portions are adapted to insert into grip holes in an external circlip. The internal connection portions are adapted to insert into grip holes in an internal circlip. The first and second pivot portions are pivotally connected with each other.
Abstract: A wrench has a first segment and a second segment pivotally coupled together. The second segment is selectively positionable at various fixed pivotal positions relative to the first segment. The first and the second segments engage with a locking device. The first segment has a first joining end forming a first positioning surface and a second positioning surface. The locking device includes a catch selectively engagable and disengagable from the first and the second positioning surfaces. The catch has a body section abutting against the first positioning surface in a direction radial to the axis of rotation when the first segment is at a first fixed pivotal position relative to the second segment. The first body section is abutted against the second positioning surface in a direction radial to the axis of rotation when the first segment is at a second fixed pivotal position relative to the second segment.
Abstract: A rotary cutter for cutting damaged threads of a bolt includes a body rotatable about a rotating axis. The body includes an inner periphery delimiting a conic cutting space. The body further includes at least one cutting blade, an evasive groove, an evasive portion, a scrap discharge groove, a scrap guide groove and a scrap discharge orifice on the inner periphery delimiting the cutting space. The at least one cutting blade forms a ridge. The evasive groove and the scrap discharge groove are respectively located on a rear side and a front side of the at least one cutting blade along a circumferential direction of the inner periphery of the body. The scrap guide groove extends between the evasive groove and the scrap discharge orifice.
