摘要： 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.
摘要翻译： 一种充油装置包括一个充油漏斗，一个可延伸管组件，一个方向调节组件和一个联接组件。 加油漏斗安装到可延伸管组件的第一端。 可延伸管组件具有安装到方向调节组件的第二端。 方向调节组件安装到可连接到发动机的注油孔的联接组件上。 方向调节组件能够相对于发动机调节可延伸管组件和充油漏斗的方向，同时可延伸管组件允许选择性地向油或填充孔移动加油漏斗。 因此，充油装置可以容纳发动机的充油孔的各种高度和角度，并允许以更平滑的方式将油填充到发动机中。

摘要： A dismounting device is provided for efficiently and effectively dismounting an environment-friendly oil filter from an engine. The device includes an oil storage container that forms an oil discharge mouth and includes an oil guide tube extending into an internal oil storage space thereof. The oil guide tube has an exposed upper end carrying a pusher in which a central bore is defined and communicating the internal oil storage space of the container. The pusher has an upper portion forming a threaded section that is engageable with an internal thread of an oil discharge opening of the oil filter and a push tube extendable into the oil filter to open an internal valve of the oil filter so that oil remaining in the filter is allowed to flow into the central bore of the pusher and is conducted by the oil guide tube into the oil storage space of the container.

摘要： A stepwise powerful suction device includes suction holders, suction elements, resilient elements, a support frame, and rotary knobs. The support frame and the three suction holders are integrally formed together. A portion of the support frame forms a handle. Each suction element forms an upright post extending through the respective resilient element and suction holder. Each suction holder forms a multi-step stepwise recess, and each rotary knob has a handgrip that forms a multi-step stepwise projection overlappingly engaging the multi-step stepwise recess and including a safety button, a spacer ring, and a bolt extending through the handgrip of the rotary knob to engage an inner-threaded hole defined in the respective suction element. Each suction holder forms a stop, and the handgrip of the respective rotary knob forms a counterpart raised portion.
