The electric knock needle disclosed in this patent is typical, however, it suffers from the following disadvantages: because the handle positioning layer is a conductive handle positioning layer, the requirements of the combination reliability and conductivity of the handle and the medical adhesive tape are required to be met at the same time, and the specification only mentions that the conductive handle positioning layer is made of plastic materials, the conductive handle positioning layer of the pressing needle is difficult to combine with the requirements of the combination reliability and good conductivity of the medical adhesive tape. Along with the development of electric acupuncture technology and the improvement of the use requirements of user groups, on one hand, an electric pressing needle is required to accurately match the current output of electric acupuncture equipment, so that the matching of the desired electric acupuncture effect and the actual effect is realized; on the other hand, the small change of the current is required to respond timely and effectively so as to meet the requirements of different stimulus intensities. This places higher demands on the electrical conductivity of the electrical knock pins, which is clearly not met by the above-mentioned prior patents.

Therefore, how to solve the above-mentioned drawbacks of the prior art is a subject to be studied and solved by the present utility model.
