Abstract: A mop includes a mop handle with a grip end and a mopping end. A locking cup is disposed on the mopping end. The locking cup includes a cup portion with interior threads and a locking tooth. A mop head is disposed at the mopping end. The mop head connects to a locking cap. The locking cap includes a locking tab configured to engage with the interior threads of the locking cup to allow for selective removal of the mop head from the mop handle and to engage and be retained by the locking tooth when the locking cap is threaded into the locking cup. A biasing element is disposed in the cup portion and contacts the locking cap and generate a bias between the locking cap and the locking cup and urge the locking tab against the locking tooth when the locking cap is threaded into the cup portion.

Abstract: A workpiece gripping device includes a base body and a pair of finger units configured to grip a workpiece. A first finger unit of the pair of finger units includes a scoop member configured to reciprocate in the direction of the arrow Z relative to the base body and rotate on a plane perpendicular to the direction of the arrow Z. A second finger unit of the pair of finger units includes a pressing member configured to reciprocate in the direction of the arrow X and rotate on a plane perpendicular to the direction of the arrow Z.

Abstract: An arrangement for working a tube end includes: an operating cylinder with a piston displaceable along an longitudinal axis; and a tube mounting, a tool holder being provided at an end of the piston facing the tube mounting. The operating cylinder is provided as a tandem cylinder. At least two cylinder stages are offset along the longitudinal axis. The piston includes connected piston segments, each piston segment being allocated to a cylinder stage.

Abstract: A pressure adjusting device of a quick fixture includes a main member, a fixed member fixed to the main member, a movable member movably connected to the main member, and an elastic member received in the main member and having opposite end connected to the fixed member and the movable member to urge the movable member. With the pressure adjusting device the quick fixture can fix various workpieces with different thicknesses.

Abstract: A substrate is arranged above a base body such that the substrate comes into contact with an upper end of a support member. Subsequently, vacuum suction is performed on an internal space of the support member through an auxiliary vacuum suction path so that the upper end of the support member is displaced to a height position equal to the height positions of upper ends of multiple protruding portions. Then, vacuum suction is performed, through a vacuum suction path, on a space of which the top and the bottom are defined by the base body and the substrate so that the substrate is brought into contact with the upper ends of the multiple protruding portions.

Abstract: The pallet changing system comprises a pallet deposition and pick-up station and a pallet loading and unloading station, horizontally spaced from one another along a first horizontal direction (A-A), as well as a pallet handling unit.
