An adjustable interior bicycle stand for storing a bicycle in the interior of a vehicle during transportation. The adjustable interior bicycle stand comprises a base and vertical supports. The base further comprises a first set of holes and a second set of holes for housing the vertical supports. The vertical supports further comprise an anchor end and a support end. The anchor end of the vertical supports being seated in the combination of the first and second set of holes of the base. The support end of the vertical supports further comprises an adjustment means and a cradle. The vertical supports further comprising an elevating means for adjusting the location of the cradle in distal relation to the base.

The present invention provides an adjustable bar clamp leveling device operable to receive a plurality of conventional woodworking bar clamps and provide space above and below a workpiece for positioning cauls and clamps to the workpiece a glue-up. A plurality of bar clamp leveling devices may be incorporated into a workbench with or without T-slots for securing a workpiece at various positions while maintaining planar alignment of the workpiece components during a glue-up.

A power tool assembly includes a base having a work surface, which is configured to receive a workpiece. A workpiece clamp assembly is moveably mountable on the work surface. The workpiece clamp assembly has a moveable clamp mount configured to fix the workpiece claim assembly in a plurality of different positions on the work surface, a clamp arm being operatively engageable with the moveable clamp mount and configured to move in a direction towards the fence, and at least one locking pin moveable between a first position and a second with respect to the moveable clamp mount wherein in the first position the at least one locking pin is configured to fix the workpiece clamp assembly to the base and in the second position the at least one locking pin is configured to release the workpiece clamp assembly from the base.

A positioning structure of a clamper of a threading machine for a racket contains: a rack, an engagement protrusion, an operation member, and two springs. A fixing holder is erected on a support plate of the threading machine, and the rack includes multiple first teeth, the fixing holder includes an accommodation chamber with an opening. The engagement protrusion is received in the accommodation chamber and includes a toothed extension on which multiple second teeth are formed. The engagement protrusion further includes a recess and an abutting fence. The operation member includes a drive portion and a push portion. The two springs are mounted on a top of the engagement protrusion, and two ends of each spring abut against the engagement protrusion and the fixing holder respectively so that each spring forces the engagement protrusion to engage with the rack.

Embodiments of a multi-purpose utility clamp may include a component engagement member having a clamp head and a handle. A guide arm is operatively connected to the component engagement member at a first end of the guide arm. A first post is operatively connected to a second end of the guide arm to move linearly relative to the guide arm. A second post at an end of the support post is disposed generally perpendicular to the first post and has a first end connected to the first post and a second end, distal the first end, and the second end is disposed opposite the clamping head. The second post has a generally trapezoidal cross-sectional shape along a length thereof between the first end and the second end, and the second post is configured to be inserted into a channel having a corresponding trapezoidal shape and formed in an auxiliary component to be clamped to another component.

A twin clamp, comprising two receptacles (61, 62), each of which has two movable clamping jaws (611, 612, 621, 622) and by means of each of which an elongate profile segment (71, 72) having a circular cross-section can be clamped in the contact section, each elongate profile segment having a centre axis (D71, D72) and an outside diameter, wherein two clamping jaws (611, 612, 621, 622) of different receptacles (61, 62) are coupled to one another via a respective differential gearing (41, 42) and two clamping jaws (611, 612, 621, 622) of the same receptacle (61, 62) are coupled to one another via a synchronous gearing (51, 52) and the position of the centre axes (D71, D72) of the clamped elongate profile segments (71, 72) is independent of the size of the outside diameters of the elongate profile segments (71, 72).

A clamp mount and workpiece alignment apparatus is provided. Clamp including a workpiece alignment apparatus is provided. A method of clamping is provided. The clamp mount and workpiece alignment apparatus is used to mount to a support surface of a workpiece support and for positioning at least one workpiece relative to the clamp while the workpiece is supported on the support surface is provided. The apparatus includes a base, a base mount, a workpiece alignment guide, a clamp mount and an adjustable interface between the base and workpiece alignment guide.

An electron block frame pouring fixture, and a method of using the fixture, the fixture including a base member having a recessed portion surrounded on each side, the recessed portion configured to receive an electron block frame therein, and a plurality of clamp members connected to the base member proximate each of the respective sides of the recessed portion, the clamp members being configured to be selectively actuated to press a received electron block frame downward into the recessed portion, wherein the recessed portion is configured to prevent lateral movement of the received electron block frame.

The present invention provides an adjustable bar clamp leveling device operable to receive a plurality of conventional woodworking bar clamps and provide space above and below a workpiece for positioning cauls and clamps to the workpiece a glue-up. A plurality of bar clamp leveling devices may be incorporated into a workbench with or without T-slots for securing a workpiece at various positions while maintaining planar alignment of the workpiece components during a glue-up.
