Along with the integration of world economy, ocean trade of various countries frequently goes on and off, offshore operation is more and more, and in addition, limited space operation such as underground is often difficult, high in labor intensity and long in time. It should be appreciated that while both economic and social developments are underway, humans are also faced with a range of hazards and challenges that threaten human safety and physical health. However, the economic development always takes the people as a basis, and after emergency injury occurs, the problem that whether an injured person can be timely cured and transported is increasingly obvious, and the requirements of rapider, accuracy, high efficiency and the like are provided for a related medical curing system in a narrow space. After primary treatment, the wounded person is transported to a rear medical institution by transport equipment such as a related vehicle and the like to receive further treatment, and in the process, the wounded person is transported mainly by virtue of the stretcher, so that whether the stretcher is applicable to a special narrow environment or not has great influence on timely treatment of the wounded person. However, due to the fact that the narrow space is narrow, the channel is steep, the turning radius is small, the channel is blocked and the like, wounded transportation is limited, the existing stretcher cannot be well adapted to the narrow environment due to the fact that the length of the existing stretcher is too long, the number of people is large, the upward and downward slopes are difficult, the turning radius is large and the like, and the rapid rescue transportation requirement of the existing stretcher in the wounded narrow space cannot be well met.

The waist mechanism 31, the adjustable long leg 34, the elastic stretching-assisting shank 35 and the foot plate 36 are respectively provided with a waist strap, a thigh strap 341, a shank strap 352 and a foot strap 362 for fixing an exoskeleton assembly wearer (i.e. a rescuer) so that the exoskeleton assembly 3 is integrated with the rescuer to better relieve the joint load of the rescuer and transmit the force applied by the angle-changing stretcher 4 to the ground through the exoskeleton assembly 3.
As shown in fig. 3,6, 7 and 8, the exoskeleton assembly 3 and the impact-type connection base 2 are connected by a first connection assembly. The first connection assembly includes a gourd hole 222 and a hook 312. The hoist hole 222 is arranged on the impact type connecting seat 2, and the hook 312 is arranged on the waist mechanism 31. In an embodiment of the present application, the hook 312 may be, for example, T-shaped, and may pass through the cavity in the gourd hole 222 and extend out, and be fastened to the upper end of the gourd hole 222, so that the impact-type connection seat 2 is connected to the lumbar mechanism 31.
As shown in fig. 8, the impact-type connector 2 includes a guide seat 22 and guide plates 227 disposed on both sides of the guide seat 22. The impact type connecting seat 2 takes the guide seat 22 as an axis to be in a symmetrical structure. The impact type connecting seat 2 is used for quickly combining and connecting the angle-changing stretcher 4 and the exoskeleton assembly 3, so that the invention is suitable for single person carrying and rescue, liberates both hands of a rescuer, and does not limit the movement of the rescuer in running and jumping.

The thorns 273 extend away from the guide sleeve 271 and form an inclined angle with the base plate 272. The extending direction of the thorn 273 is opposite to the opening direction of the backup plate hole 412, so that the thorn 273 can be connected with the backup plate hole 412 on the backup plate 41 in a one-way locking manner. In an embodiment of the present application, the backup plate hole 412 may be, for example, an arc-shaped hemisphere, and when the spine 273 contacts with the backup plate hole, the spine 273 may abut against the inner surface of the arc-shaped hemisphere, so that the angle stretcher 4 is stably connected with the impact-type connecting seat 2 under the gravity condition, thereby facilitating the rescuer to adjust the height of the angle stretcher 4 on the back of the rescuer, and further changing the height of the angle stretcher 4 relative to the ground. The second connecting component can insert the thorns 273 into the backup plate holes 412 with different heights according to the environmental conditions such as the ground, so as to facilitate the adjustment of the height of the lifting stretcher, thereby adjusting the different back height requirements of the stretcher relative to the rescuer. As shown in fig. 7, the guide plate 227 is laterally symmetrical and is outwardly opened to guide the direction of the backup plate 41 toward the floating ratchet plate 27 of the striking-type connection base 2, so as to reduce the alignment difficulty and allow the angle-variable stretcher 4 to be quickly connected to the striking-type connection base 2.
