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.

1. An oil filling device, comprising: an oil filling funnel, which has a lower end to which an insertion connector is connected, the insertion connector having a lower end to which an angled fitting is mounted in such a way that a funnel hole of the oil filling funnel, a connector hole of the insertion connector, and an angled fitting hole of the angled fitting are in communication with each other;an extendable tube assembly, which comprises a first tubular member having a first end to which an end of the angled fitting is fit so that the angled fitting hole is in communication with a first bore defined through the first tubular member, the first tubular member having an opposite end to which an end connector is mounted, the end connector forming therein a tapered bore that comprises at least a tapering section that receives and retains therein a conical wedge block that has a C-shaped cross-section, a second tubular member being telescopically received through the conical wedge block and into the first tubular member, a fastening element having an internally threaded hole that is set in engagement with an external thread of the end connector, whereby with the second tubular member being telescopically moved with respect to the first tubular member to assume a desired length, the fastening element is rotated to drive the conical wedge block further into the tapered bore to get compressed and simultaneously fix the first tubular member and the second tubular member to each other, the first bore being in communication with a second bore defined through the second tubular member;a direction adjustment assembly, comprising a rotary adjustment knob, a fastening knob, and a T-shaped fitting, the T-shaped fitting having a top portion forming a lateral passage to receive the rotary adjustment knob to extend therethrough in such a way that the rotary adjustment knob is rotatable with respect to the T-shaped fitting, the T-shaped fitting comprising a vertical passage formed therein to extend downward from and in communication with the lateral passage, the rotary adjustment knob having a first end forming an internally threaded hole that engages an external thread formed at a free end of the second tubular member and an opposite second end forming a hole in communication with the internally threaded hole, the rotary adjustment knob having a circumferential wall in which a plurality of through holes is formed to correspond to the vertical passage to communicate with the vertical passage, the rotary adjustment knob comprising an external thread formed at the second end thereof to engage an internal thread formed in the fastening knob, whereby when the rotary adjustment knob is rotated and set at a desired angular position, the fastening knob is rotated to abut against the T-shaped fitting and thus secure the rotary adjustment knob in position; anda coupling assembly, which comprises a locking cap, the locking cap forming an insertion bore to receive and retain the T-shaped fitting in such a way that the vertical passage is in communication with the insertion bore, the locking cap having a lower end forming an external thread adapted to engage an internal thread of an oil filling opening of an engine in such a way that the insertion bore is in communication with the engine, the external thread of the lower end of the locking cap being selectively provided with a gasket set around an outer circumference thereof. 2. The oil filling device as claimed in claim 1, wherein the locking cap has a side portion forming an inverted T-shaped vent hole in such a way that the inverted T-shaped vent hole has a first opening that is in communication with the engine, a second opening that is formed in a side surface of the locking cap to communicate with the outside atmosphere, and a third opening that is formed in the top of the locking cap to communicate with the outside atmosphere.
