Zusammenfassung:	The utility model relates to a reel oiling structure which comprises an oil gun (1). The utility model is characterized in that the gun head of the oil gun (1) is an fine steel pipe (2) with an external thread (21), and the oiling port (42) in an oiling channel (4) is provided with an internal thread (41) which can be screwed with the external thread (21) of the fine steel pipe (2) during charging. When oil is not charged, the oiling port (42) is provided with a choke plug (3) which is screwed with the internal thread (41) on the oiling port (42) via an external thread (31). The utility model of the novel oiling structure only employs a common internal hexagonal wrench to disassemble the choke plug and then to screw the choke plug on the fine steel pipe of the oil gun, thus the oiling operation is very convenient. And what's more, the gun head of an original oil gun is improved into the fine steel pipe with the external thread at the head, and the external thread on the fine steel pipe is screwed and engaged
