Abstract: An adjustable dismantling tool for annular member is provided. A handle has opposing first end and second end and an axial direction passing through the first and second ends. A first main body is disposed at the second end and radially unmovable relative to the axial direction. A second main body is rotatably assembled with the first main body, radially unmovable relative to the axial direction and radially formed with a plurality of guiding troughs relative to the axial direction. Each of movable members has a guiding block slidably disposed in corresponding guiding trough. Each of connecting arms is disposed between the first and second main bodies, pivoted to the first main body and one of the guiding block to respectively form a first pivoting portion and a second pivoting portion, and swingable about the axial direction with the first pivoting portion as the center.

Abstract: A hub removal tool is provided, including a base, a first working member and a threaded rod. The base has at least one positioning hole and an assembling hole penetrating therethrough in a first direction. The assembling hole defines a central axis extending in the first direction. The first working member is disposed on the base. The first working member has a first screw hole. An opening direction of the first screw hole is identical to the first direction. As viewed in the first direction, the first screw hole is located in a distribution area of the assembling hole and a first axis of the first screw hole is misaligned with the central axis. The threaded rod is screwed with the first screw hole and is movable in the first direction.
