The tunnel emergency rescue apparatus according to claim 2, wherein: the lower extreme of shank support frame (4) still is equipped with connection supporting seat (10), the upper end of supporting foot (6) is equipped with bottom sprag seat (9), the internally mounted of connection supporting seat (10) has quadrilateral support inner frame (11), quadrilateral support inner frame (11) are used for rotating connection supporting seat (10) and bottom sprag seat (9).

4. The method of using a tunnel emergency rescue device according to claim 1, wherein: comprises the following steps of the method,

s1, wearing the device: attaching the supporting framework (1) to the hip position of the rescue personnel, enabling the hip joint of the rescue personnel to be located at the joint of the thigh supporting frame (3) and the supporting framework (1), attaching the spine attaching frame (2) to the back of the rescue personnel, and attaching the armpit bracket (21) to the armpit position of the rescue personnel;

s2, stretcher connection: the patient is laid on the upper end of the simple stretcher (20), before the stretcher is lifted by a rescuer, one end of the return hook (34) is clamped in the bottom clamping hook frame (33) to form a fixed state, the patient is supported by the shoulder straps (22), and meanwhile, downward acting force is applied to the shoulder buffering cotton block (23) and acts on the shoulder position of the rescuer, and labor-saving operation is provided for the lifting of the stretcher;

s3, supporting: the supporting spring (30) is used for generating outward spring-opening acting force, driving the supporting movable column (27) and the fixed sleeve (28) to be unfolded, simultaneously, driving the connecting sleeve (29) to be pushed downwards through the fixed sleeve (28) and driving the connecting shaft rod (32) to be pushed downwards, enabling the semicircular supporting frame (31) to rotate and driving the supporting rod (15) to be lifted upwards, supporting the positioning bracket (16), driving the driving threaded column (26) to rotate through rotating the inner hexagonal shaft pin (25), enabling the driving threaded column (26) and the inner wall of the supporting movable column (27) to form a threaded engagement connection state, driving the supporting movable column (27) to realize lifting operation, and providing a function of adjusting expansion and contraction pressure for the supporting rod (15) and the positioning bracket (16);

s4, structure cooperation installation: after a plurality of backbone laminating frames (2) are installed in a combined mode, a backbone-shaped structure is formed, the bending state of the backbone laminating frames (2) can be automatically adjusted according to the back of a rescue worker, the back of the rescue worker can be tightly laminated, the height of a supporting top frame (38) can be adjusted through rotating a threaded column (37), the gap between two backbone laminating frames (2) is changed, the bending structure of the backbone laminating frames (2) is adjusted, and the bending degree is improved, so that the backbone laminating frames (2) are tightly laminated with the back of the rescue worker.
