Abstract: A dusting tool having a flexible skeletal element including a base, from which four elongated arms extend. The elongated arms have a base end and a distal end. The base ends extend from the base and being spaced apart from one another at the base. The arms being flexible and resilient. A plurality of cross-members extend between the elongated arms, a plurality of living hinges being disposed between the plurality of cross-members and the elongated arms. A force applied to at least one of the elongated arms is transmitted to the other of the elongated arm by the plurality of cross-members and the plurality of living hinges.

Abstract: A lowering mechanism for a hand held jacking tool comprises a caulking gun jacking mechanism. The lowering mechanism comprises a lowering plate on top of the holding plate, a pushing lever connected with a hinge attachment to the lowering plate at a rear end, wherein the pushing lever is pivoting around a pivot structure connected to the lever or holding plate a distance backward from the hinge attachment, causing the lowering plate to grip the jacking shaft when the lever is pushed downwards and then, in turn, pushing the holding plate downwards and loosening it from the jacking shaft and moving it down along the jacking shaft a distance determined by the pivoting action of the lever. The lowering plate is held in place by a spring biasing the lowering plate towards the holding plate.
