Abstract: A pneumatic pressure pulse cleaning machine includes a container body, which has a rear side to which a container cover is rotatably mounted and also has an interior space in which a pipe assembly that includes pipes connected together to form a grating configuration is received. The pipe assembly has a plurality of through holes formed therein and facing upwards. A support board is received in the interior space and arranged above the pipe assembly so that an article disposition zone is provided in the container body above the support board. The pipe assembly includes a joint, which is connectable with a tube for connection with a pneumatic pressure source. Articles to be washed are positioned on the support board. The pneumatic pressure source is activated to generate pneumatic pressure pulses that are ejected through the through holes to impinge and thus clean the articles.

Abstract: A trigger-boosting pulling device includes an elongate shank, which receives a backward ram to slidably fit thereon, a suction cup, which is fixed to a rear end of the elongate shank, a hand-operating pump structure, which is fixed to a front end of the elongate shank and includes a T-shaped pull grip that is connected by a connection bar to a piston assembly. The connection bar includes a spring fit thereon for position restoration of the pull grip. The pump cylinder includes a handle mounted thereto. The handle has a trigger that is arranged to drive, via a connection lever, the connection bar. As such, the T-shaped pull grip can be first pulled to induce a suction force to reach an initial level and then the handle is held by a hand and the trigger is pulled to drive the connection lever for doubling the force so as to induce enhanced vacuum suction force in the suction cup.

Abstract: A suction device adapted to reliably support a force created by a person pulling on or otherwise using the device. Engaging an activating element allows a user to increase or reduce the vacuum generated by the device, the amount of which is visibly determinable using an indicator. Once in place, the activating element may be locked so as to prevent a user from inadvertently raising the activating element, and thereby reducing the suction generated by the device.

Abstract: A pump includes a cap that is fit into an opening of a pump body. The pump body has an external thread formed on an outer circumference close to a top face thereof for engagement with and coupling to a rotatable fixing ring having an internal thread so as to retain a cap from top side thereof. The threading engagement along the circumference fixes the cap and the pump body together. The cap has an underside from which a projecting ring extends downward. The projecting ring has a thread. A piston cylinder has an end forming a thread engageable with the thread of the projecting ring to complete the assembling of the piston cylinder.

Abstract: An oil filling device includes an oil filling funnel, an extendable tube assembly, a direction adjustment assembly, and a coupling assembly. The oil filling funnel is mounted to a first end of the extendable tube assembly. The extendable tube assembly has a second end mounted to the direction adjustment assembly. The direction adjustment assembly is mounted to the coupling assembly that is attachable to an oil filling hole of an engine. The direction adjustment assembly enables adjustment of the direction of the extendable tube assembly and the oil filling funnel with respect to the engine, while the extendable tube assembly allows the oil filling funnel to be selectively moved toward or away from the oil filling hole. Thus, the oil filling device may accommodate various heights and angles of oil filling hole of engine and allows filling of oil into the engine to be conducted in a smoother manner.
