The present invention relates to a multipurpose stimulation massager having a variable assembly and use function. The objective of the present invention is to provide the multipurpose stimulation massager having the variable assembly and use function, in which multiple combined stimulation members are formed that achieve selective skin stimulation effects such as friction, acupressure, thermotherapy, low-frequency vibration, and ultrasonic wave generation and antimicrobial effects along with each other and a set configuration is realized by means of application-specific variable installation members where the combined stimulation members are selectively combined and mounted, examples of which include a toothbrush-type member, a massage-type member, and a mat-type member, so that a user can install the combined stimulation members in the variable installation members in a replaceable and detachable manner depending on the purpose of use that is required and use them and the use can cover a wide range of applications at any body parts such as gum stimulation, scalp stimulation, face massage, and body skin stimulation. As specific means according to the present invention for achieving the objective described above, the combined stimulation member in which a contact guiding tool, a fixed support, and a fastening guiding tool are integrated with one another is prepared. The prepared combined stimulation member is fastened to and mounted on the variable installation member that is made up of any one configuration among the toothbrush-type member having a toothbrush head, the massage-type member having a friction head, and the mat-type member having an upper plate for installation.본 발명은 가변조립 사용기능을 갖는 다용도 자극 마사지기에 관한 것으로;그 기술구현의 목적은, 마찰, 지압, 온열, 저주파진동, 초음파 등의 선택적인 피부자극 작용과, 항 미생 작용을 병행하는 다수개의 조합자극 부재를 형성하고, 상기 조합자극 부재가 선택적으로 조합 장착되는 용도별 가변설치 부재, 예컨대, 칫솔형 부재, 마사지형 부재, 그리고, 매트형 부재 등으로 세트화 구성하여, 사용자가 필요로 하는 사용목적에 따라 그들 가변설치 부재에, 조합자극 부재를 탈,부착 교환구조로 설치사용 가능하게 함으로서, 어느 특정된 신체부
