[0038] A winding mechanism 5 is installed in the internal rotation of the second connecting rod 2. One end of the supporting cloth 3 is fixedly connected to the side wall of the first connecting rod 1, and the other end of the supporting cloth 3 is connected to the winding mechanism 5. A locking mechanism for limiting the rotation of the winding mechanism 5 is provided between the second connecting rod 2 and the winding mechanism 5. By arranging the supporting cloth 3, the telescopic frame 4, the winding mechanism 5 and the telescopic support plate 6, the width between the first connecting rod 1 and the second connecting rod 2 is adjusted according to the body shape of the wounded through the telescopic frame 4 during use. During the movement of the first connecting rod 1 and the second connecting rod 2, the locking mechanism is released from the winding mechanism 5, thereby pulling out the supporting cloth 3 wounded on the winding mechanism 5, which can realize the adjustment of the width of the stretcher and make the stretcher adaptable to the use of wounded people of different body shapes.

A sleeve 403 is provided between the first and second connecting blocks 401 and 402 for connecting the first and second threaded rods 404 and 405. It should be noted that when the sleeve 403 is rotated during use, the first and second connecting blocks 401 and 402 will extend from the interior of the sleeve 403, thereby cooperating with the first and second connecting blocks 401 and 402 to adjust the width between the first and second connecting rods 1 and 2.

[0047] like Figure 1 、 Figure 2 and Figure 3As shown, as a preferred embodiment, based on the above-mentioned method, the first threaded rod 404 and the second threaded rod 405 have opposite rotation directions, the sleeve 403 is provided with two sections of threads that respectively cooperate with the first threaded rod 404 and the second threaded rod 405, and the first connecting block 401 and the second connecting block 402 are fixedly connected to a handle 7. It should be noted that there are four handles 7, so that when the stretcher is in use, it can be carried by two people or four people working together. When the sleeve 403 is rotated, the first threaded rod 404 and the second threaded rod 405 fixedly connected to the first connecting block 401 and the second connecting block 402 will extend or retract into the sleeve 403, thereby cooperating with the first connecting block 401 and the second connecting block 402 to adjust the width between the first connecting rod 1 and the second connecting rod 2.

[0048] Specifically, the working principle of the adjustable wounded transfer stretcher is as follows: when choosing to use the telescopic support plate 6 to transport the wounded, the telescopic support plate 6 is movably installed on the top of the first connecting rod 1 and the second connecting rod 2 through the clamping block 803 and the clamping slot 804 during use, and then the width between the first connecting rod 1 and the second connecting rod 2 is adjusted through the telescopic frame 4. When the auxiliary support plate 802 is adjusted to the maximum distance extending from the inside of the main support plate 801, the telescopic support plate 6 will be stuck between the tops of the first connecting rod 1 and the second connecting rod 2, thereby completing the fixation of the three. At this time, the first connecting rod 1, the second connecting rod 2 and the telescopic support plate can be used. The plate 6 is used to transfer the wounded. When the stretcher is not in use, the telescopic support plate 6 can be removed from the first connecting rod 1 and the second connecting rod 2, and then the multiple telescopic rods 8 can be folded or rolled up. The elastic rope 9 can prevent the multiple telescopic rods 8 from spreading out. After the telescopic support plate 6 is rolled up, the winding rod 501 can be rotated by the turntable 502 to roll up the supporting cloth 3 onto the winding rod 501, so that the first connecting rod 1 and the second connecting rod 2 are attached together. After the supporting cloth 3 is rolled up, the limiting rod 503 threadedly connected to the turntable 502 is rotated to insert it into the limiting hole 11 to fix the winding rod 501, thereby completing the folding and storage operation of the stretcher.

[0049] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
