Rapid take-up and pay-off device for detection line

The utility model relates to the field of lightning protection detection devices, in particular to a detection line rapid take-up and pay-off device which comprises a take-up and pay-off wheel used for winding a detection line, the end face of the take-up and pay-off wheel is rotationally connected with a line storage bin, and the line storage bin is slidably connected with a positioning ejector pin used for driving the detection line to be wound on the take-up and pay-off wheel. The positioning ejector pin slides in the direction perpendicular to the rotating axis of the wire storage bin, and when one end of the positioning ejector pin extends out of the wire storage bin, the detection wire abuts against the side face of the positioning ejector pin. The take-up and pay-off wheel is provided with a pushing face used for pushing the detection line to move in the direction away from the line storage bin. The take-up and pay-off device has the effects that winding of the detection wire on the wire coil during ta
