The first arm brace 22 and the second arm brace 23 are located on one side of the front surface of the base 1. The central axes of the first arm brace 22 and the second arm brace 23 are located on the same straight line, and the two can rotate around the hinge joint in the directions approaching to or separating from each other. The hinged ends of the first arm brace 22 and the second arm brace 23 are close to each other, the ends of the first arm brace 22 and the second arm brace 23 far away from each other respectively penetrate out from the two ends of the sleeve 7, and the first arm brace 22 and the second arm brace 23 penetrating out from the side wall of the sleeve 7 are inserted and fastened on the side wall of the opposite pull rod 8.

As shown in fig. 5 and 8, a large number of mounting holes 11 are formed in the pull rod 8 and the sleeve 7 at uniform intervals, the back of the base 1 is provided with a canvas 12 for transporting the wounded through the mounting holes 11, a circumferentially surrounding hook is mounted on the canvas 12, and the canvas 12 can be fixedly mounted on the back of the base 1 by clamping the hook into the corresponding mounting hole 11, so that the wounded can be transported.

The specific effects of the embodiment are as follows:

when the search and rescue is carried out to the rescue personnel at dark night, pull out crane 2 from base 1, adjust the emergency light 4 at 3 both ends of crossbearer to suitable position again, realized the illumination function to the road through emergency light 4 to make things convenient for the search and rescue personnel to carry out the rescue work at night. The alarm signal lamp 26 is turned out from the back of the emergency lamp 4, so that the person waiting for rescue can clearly observe the rescue signal through the alarm signal lamp 26 and can be in contact with the rescue person in time, and the efficiency of search and rescue can be improved. When a wounded person with inconvenient actions is met, the sleeves 7 on the two sides of the sliding seat 5 are pulled out in the direction of mutual separation, and the sleeves 7 drive the two ends of the telescopic rod 6 to respectively slide out of the sliding seat 5. With the distance between the sleeves 7, the second connecting rod 10 will gradually slide out from the first connecting rod 9, so that the whole length of the pull rod 8 is stretched along with the telescopic rod 6. The pull rod 8 is then pulled out of the sleeve 7 in the direction of the length of the sleeve 7, the extension of the entire length of the sleeve 7 being achieved by the pull rod 8. After the positions of the stretched draw bar 8 and the telescopic bar 6 are fixed, the canvas 12 is finally tensioned and fixed on the back of the base 1 through the mounting hole 11, thereby forming the stretcher for transporting the wounded. When the wounded lies on the stretcher, because base 1 is located the central point of stretcher, can support wounded's back through base 1 to can improve wounded's holistic comfort level. Through in pushing into sleeve pipe 7 with pull rod 8, remove sleeve pipe 7 to the direction that is close to gradually again to just can accomodate the stretcher, the whole convenience of accomodating the process ten minutes can reduce the holistic area of base 1 after accomodating the stretcher, has realized the effect that conveniently carries.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the design concept of the present invention should be included in the scope of the present invention.
