Abstract: The present invention provides a fishing rod and spinning reel holding device equipped to signal a fisherman of a striking fish. The signaling mechanism has a axially mounted crank shaft which directly contacts onto a fishing line on one side of the crank shaft. The other side of the crank shaft is fitted with a hooked retainer for retaining a flagging unit such as a springed flag staff in a non-signaling position. When a striking fish tugs upon the fishing line, the fishing line forces the crank shaft to pivotally move about its axial mount and cause the hooked retainer to release the flagging unit to a flagging position and thus give the signal of the striking fish.
