A strap type electric stimulator includes: a body, a buckle module and a control module； wherein an electrode portion is disposed at one end of the front surface of the body, and the body is provided with a flexible surface on a back surface of the electrode portion a plurality of first coupling members on the back surface, the back surface being extensible at a free end opposite to the other end of the flexible portion, and a second coupling member is disposed on the end of the free end； the buckle module Provided on the end of the flexible portion of the back surface； the control module is disposed between the first bonding component of the back surface and the buckle module； thereby, the body is wrapped on the bound object In this case, it is only necessary to adjust the second bonding component to be coupled to the first bonding component at different positions to adjust the tightness of the body coating, and can be applied to the bundled components of different sizes.一種綁帶式電刺激器，包括：一本體、一扣環模組及一控制模組；其中，該本體正面之一端上設一電極部，該本體相對該電極部之背面上設一可撓部，該背面上設數個第一結合元件，該背面在相對該可撓部之另一端的自由端係具有可延伸性，該自由端的末端上設一第二結合元件；該扣環模組設於該背面之可撓部的末端上；該控制模組設於該背面之該等第一結合元件與該扣環模組之間；藉此，將該本體包覆於被綁縛物上時，僅需調整該第二結合元件結合於不同位置之第一結合元件上，即可調整該本體包覆之鬆緊，而能適用於各種不同尺寸大小之被綁縛物上。
