Disclosed are a snap-fit structure of an electrode. The structure comprises: an upper cover, a conductive sheet, a spring, a button, and a lower cover. A button groove is provided on an upper end surface of the lower cover, and is provided with the button. The spring is provided at an inner side of the button groove. The button groove is further provided with the conductive sheet. The upper cover is covered above the button groove. A second fixed hole is provided on the conductive sheet, the second fixed hole is formed by connecting two hole positions having inconsistent diameter, a third fixed hole is provided on the button, and the spring is provided in the button groove, so that when an electrode plate is fixed, the third fixed hole on the button is moved by pressing the button so as to drive the electrode plate inserted into the third fixed hole to move, and when the button is released, the electrode plate is driven by the third fixed hole to a through hole and a small hole position of the second fixed hole so as to fixedly fasten the electrode plate by means of the second fixed hole and the third fixed hole, thereby avoiding the situation that the electrode plate is easy to detach in the traditional pressing mode.La présente invention concerne une structure d'encliquetage d'une électrode. La structure comprend : un couvercle supérieur, une feuille conductrice, un ressort, un bouton, et un couvercle inférieur. Une rainure de bouton est disposée sur une surface d'extrémité supérieure du couvercle inférieur, et est munie du bouton. Le ressort est disposé au niveau d'un côté interne de la rainure de bouton. La rainure de bouton est en outre munie de la feuille conductrice. Le couvercle supérieur est recouvert au-dessus de la rainure de bouton. Un second trou fixe est disposé sur la feuille conductrice, le second trou fixe est formé par connexion de deux positions de trou ayant un diamètre incohérent, un troisième trou fixe est disposé sur le bouton, et le ressort e
