The present invention comprises a wheelchair body (100), a 3 step angle adjustment type bed transforming module (200), a rotary arm rest (300), a sliding guide rail part (400), a hydraulic lifting and dropping drive part (500) and driving wheels (600), in order to improve a problem whereby a movement is inconvenient due to a structure where a height of an existing wheelchair body is different from that of a specific object composed of a bed, a table and a chair, a patient that can only stand up towards a front side and a problem where a movement is difficult in a case where the body size of a guardian is smaller than that of a patient, a movement to other position is difficult by himself or herself without a helper in a case where a paralyzed patient or a patient whose behavior is inconvenient, and a patient may sustain a secondary injury when the patient is wrongly moved because a method to move the patient is different according to the patient&prime；s symptom. The present invention can safely move the patient when an emergency occurs and adjust the height according to the height of a specific object； minimize a body contact between the guardian and the patient by sliding in a left and right direction； prevent secondary injury because a patient&prime；s posture is not changed； enhance stability by minimizing difficulty in going to the guardian； reduce, above all, the accidents occurring when moved from the wheelchair to the specific object under 80% as compared with a conventional wheelchair； have a simple structure and better transformability； and widely be put to practical use in a hospital or a sanatorium because the price is low.본 발명에서는 기존 휠체어몸체의 높이가 침대, 식탁, 의자로 이루어진 특정객체의 높이와 서로 다르고, 전면으로밖에 일어날 수 없는 구조로 되어 있기 때문에 이동이 불편한 문제점과, 보호자가 환자보다 체형이 작을 경우에 이동이 힘들고, 마비환자나 거동이 불편한 환자의 경우에는 도우미의 도움없이 혼자서 다른 위치로 이동시키는 것이 어렵고, 환자의 증상에 따라 환자를 이동시키는 방법이 다르기 때문에, 잘못 이동시, 환자에게 2차적인 부상을 일으키는 문제점을 개선하고자, 휠체어본체(100), 3단각도조절형 침대가변모듈(200), 회전형팔거치대(300), 슬라이딩안내레일부(400), 유압승하강구동부(500),
