[0034] Specifically, refer to Figure 1 The labor-saving stretcher suitable for field rescue also includes several straps 5 and buckles 6. The fixed ends of the straps 5 are installed on the stretcher poles 11 and are arranged in pairs on two stretcher poles 11. The free ends of the straps 5 are fixed to the paired straps 5 through the buckles 6 to fix the patient and avoid problems such as shaking of the patient's body during movement.

[0035] This labor-saving stretcher suitable for field rescue is further explained with a specific usage process:

[0036] When in use, the rescuer wears the harness body 3, so that the two shoulder straps 31 pass over the rescuer's shoulders and cross on the back of the human body, and the two shoulder straps 31 are fixedly connected to the waist belt 32. The lengths of the shoulder straps 31 and waist belt 32 can be adjusted according to the rescuer's needs through the adjustment buckles 34 on the shoulder straps 31 and waist belt 32. The first connecting section 321 and the third connecting section 323 of the waist belt 32 are respectively located on the front and back of the rescuer, and the second connecting section 322 and the fourth connecting section 324 are respectively located on both sides of the rescuer's body. The harness body 3 is installed on the ring installation section 111 through the connecting ring 2, and the lengths of the shoulder straps 31 and waist belt 32 can be adjusted according to the rescuer's needs. Figure 1 and Figure 6 , insert the second ring body 22 of the connecting ring 2 into the stretcher pole 11 and make it located at the ring mounting section 111, and make the inner side of the engaging portion 23 located at the plane where the two planar portions 1112 are located; Figure 7 and Figure 8 The engaging portion 23 engages the two planar portions 1112 and moves along the two planar portions 1112 until the inner side of the first ring body 21 is in contact with the arc-shaped portion 1111; Figure 9 , rotate the connecting ring 2 so that the engaging portion 23 cannot move along the plane portion 1112, refer to Figure 1 and Figure 4 The arcuate portion 1111 is a curved surface that bends toward the axis of the stretcher pole 11. After installation, the connecting ring 2 can only rotate along the circumference of the arcuate portion 1111 and cannot move forward and backward along the length of the stretcher pole 11. Rescuers adjust the lifting straps 33 to properly distribute the pressure on their hands and shoulders when lifting the stretcher. When transporting patients in the field and encountering rough roads, rescuers can adjust the main body of the shoulder strap 31. The provision of the rotating ring 4 and the rotatable structural design of the connecting ring 2 after installation also allow for fine-tuning of the relative position of the rescuer and the stretcher body 1, preventing the rescuer from being strangled by the shoulder strap body 3 and facilitating posture adjustment.

[0037] In the embodiment of the present application, the shoulder strap 31 body is detachably mounted on the stretcher body 1 through the connecting ring 2. The connecting ring 2 is easy to install, firmly installed and not easy to fall off, and can be rotated and fine-tuned during use. The structure is ingenious, which is not only labor-saving and practical, but also improves the safety of the stretcher. The stretcher is lifted alternately or in combination by the shoulders and hands, which reduces the physical exertion of rescuers.

[0038] The above embodiments are only used to further illustrate the technical solutions of the present invention, but the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention fall within the scope of protection of the technical solutions of the present invention.
