The utility model relates to the field of acupuncture needle detection devices, in particular to an acupuncture needle spring winding pay-off detection device which comprises a detection table and an acupuncture needle body. A first groove and a second groove are formed in the upper end of the detection table. The spring on the side wall of the acupuncture needle body is pulled through the two test ropes, when pulling of the first test rope and the second test rope is released, the spring can rebound, if the spring can completely rebound after being pulled by a certain distance, the quality is intact, and if the spring cannot completely rebound, the tension and the stability of the spring are insufficient, so that the acupuncture needle is safe and reliable. Besides, a testing block can be attached to a spring of the acupuncture needle body, a third electric cylinder is started to enable an output shaft of the third electric cylinder to abut against a supporting block, the testing block is positioned, and therefore during tension testing, the spring pulled by a first testing rope can only be compressed in a small range, and tension testing in another form can be achieved.
