A quick attachment feature for a filter includes i) a pair of radially-outward projecting pivots on opposite sides of the filter canister toward a lower end thereof; and ii) a pair of flexible retaining clips also located on opposite side of the canister toward the upper end thereof, each clip in substantial axial alignment along the canister with a respective pivot. The filter can be supported in a bracket including a pair of side walls, each of the side walls including i) a hook-shaped opening dimensioned to receive a respective pivot on the filter, and allow the filter to pivot from an orientation at an angle to the longitudinal axis of the bracket, to an orientation where the filter is substantially axially-aligned with the bracket; and ii) a catch dimensioned to engage and retain a respective retaining clip, when the filter is substantially aligned with the bracket.

A replacement bus system having one or more conductive shafts supporting wire attachment lugs and spacers that ride along the conductive shaft; the spacers are conductive and separate the attachment lugs. The lugs and spacers may be secured onto the shaft by a locking mechanism. By providing a shaft on which the lugs may ride, the wires are configured transversely to conventional approaches, enabling a greater number of wires to be connected over a given length and a wider variety of relative orientation of wires. This configuration also enables much of the structure to be manufactured from stainless steel or other non cuprous metal, except for the spacers, which may be manufactured from tinned copper.

The working component has the following beneficial effects: the working component can be fit with shaft ends in various shapes; and meanwhile, an adapter is directly arranged on the connection portion of the working component, thus reducing the accessories of multifunction tools and ensuring the multifunction tools to have portability.

An outboard engine with a cover for allowing for an improved outward appearance is disclosed. The engine includes a leg case that houses a drive shaft for transmitting the output from the engine to a propeller. The cover covers the leg case. The cover is formed integrally, and a front part is designed to be opened. The front part is opened and is made to encase and cover a periphery of the leg case.

The invention discloses a combined type stair formwork. The combined type stair formwork is a mold assembly defined by six main form boards and provided with two steps. Each main form board is formed by vertically welding reinforcing battens to the periphery of a flat plate. Bolt holes for mounting of the side face main form boards are machined in the front battens and the rear battens of the upper step and the lower step, and a tubular sleeve for drawing is welded to the crossed position of the middle batten of the main form board of the upper step. A bolt through hole for fixing the upper main form board is machined in the left side of the middle batten of the lower step. A porous square plate is fixed to the side face of the through hole through a bolt. The left end of the square plate and the battens of the upper main form board are welded. An inclined guide pipe is welded to the right end of the middle batten of the lower step. The combined type stair formwork has the advantages of being simple in structure, easy to mount, convenient to operate, small in size, small in number of accessories, low in machining cost, low in labor intensity, wide in application range, safe, reliable and the like.
