[0002] Stretchers are emergency rescue equipment, usually used to transport patients. Stretchers can be classified into the following categories according to different fields: medical field, such as hospital stretchers, which are used for daily emergency and patient transportation; military field: such as ship stretchers, and stretchers used in land combat and other scenarios; fire fighting field, stretchers used in firefighting and rescue, used to rescue the wounded in accidents such as fires; outdoor sports field, used for the transportation of injured people in outdoor adventures, mountaineering and other activities; disaster rescue field: special stretchers used in major disasters such as earthquakes and floods.

[0003] Ship stretcher products are mainly used for transporting wounded in a narrow space inside the ship or transferring wounded and sick patients lying between ships. They need to be able to be used in a narrow space and adapt to the possible shaking of the ship during navigation. They need to better fix the patient to prevent the patient from suffering additional injuries due to shaking. They need better portability, fixation and stability. After searching, the applicant found the closest prior art as follows:

[0004] Application number CN201920307248.0 is a folding stretcher, which discloses a technical solution, including a stretcher bar A and a stretcher bar B.
