[0022] Refer to​Figures 1-5 The utility model provides a telescopic shovel stretcher with adjusting function, including stretcher main rod 1, stretcher vice rod 11 and split buckle 2, stretcher main rod 1 and stretcher vice rod 11 are all provided with two, the inside of two stretcher main rod 1 is slidably connected with main connecting rod 14, the inside of two stretcher vice rod 11 is slidably connected with vice connecting rod 12, the circumference of two main connecting rod 14 and two vice connecting rod 12 is all installed with split buckle 2, two main connecting rod 14 and two vice connecting rod 12 are connected through two split buckles 2 respectively, the circumference of two stretcher main rod 1 and two stretcher vice rod 11 is all set up sliding hole 19, the circumference of two stretcher vice rod 11 is all fixedly connected with vice support plate 10, the circumference of two stretcher main rod 1 is all fixedly connected with first main support plate 5, vice support plate 10 is located the left end of first main support plate 5, the inside of two first main support plate 5 is slidably connected with second main support plate 6, the left and right two end surfaces of two first main support plate 5 are all set up second through hole 15, the inside of two second main support plate 6 is slidably connected with second connecting rod 13, two second connecting rod 13 are all through second through hole 15 and sliding hole 19 towards left end, pass through first main support plate 5, stretcher vice rod 11 and vice connecting rod 12, and are fixedly connected with vice connecting rod 12, the right end of two second main support plate 6 is all fixedly connected with first connecting rod 7, two first connecting rod 7 pass through second through hole 15 and sliding hole 19 towards right, pass through first main support plate 5, stretcher main rod 1 and main connecting rod 14, and are fixedly connected with main connecting rod 14, the circumference of two first connecting rod 7 and two second connecting rod 13 is all threadedly connected with nut 16, two stretcher vice rod 11 respectively extend to two first main support plate 5, the circumference of two stretcher vice rod 11 is all set up a plurality of slot 18, the left end of two stretcher main rod 1 is all fixedly connected with fixed part, and fixed part is used in stretcher vice rod 11 with slot 18 cooperation. When working, the utility model is convenient for adjusting the width and length of shovel stretcher, so as to use the stretcher to use the patient of different volume and different height.

[0023] Further, the circumference of two first main support plate 5 is all fixedly connected with fixed plate 3, the upper end surface of a plurality of fixed plate 3 is all set up mounting hole 4. When working, after the patient lies on the shovel stretcher, the two ends of the bandage are respectively threaded through the fixed plate 3 through the two mounting holes 4, then the bandage is tied on the bottom end of the shovel stretcher, which is convenient for fixing the patient and reduces the probability of falling off the shovel stretcher.

[0024] Further, the left end face of each of the two support plates 10 is provided with a first through hole 9, and the two second connecting rods 13 pass through the two support plates 10 through the two first through holes 9 respectively; the first through hole 9 is located between the second through hole 15 and the sliding hole 19, and the width of the first through hole 9 is the same as that of the second through hole 15 and the sliding hole 19. During operation, the existence of the support plate 10 not only supports the patient, but also makes the support plate 10 not easily affect the adjustment of the position of the connecting rod 12 due to the existence of the first through hole 9.

[0025] Further, the fixing member includes a fixing block 8 and a threaded fastening rod 17, and the left end of each of the two stretcher main rods 1 is fixedly connected with the fixing block 8, the interior of each of the two fixing blocks 8 is threadedly connected with the threaded fastening rod 17, and the threaded fastening rod 17 is inserted into the corresponding slot 18. During operation, the threaded fastening rod 17 is rotated along the fixing block 8, and moves until the threaded fastening rod 17 is separated from the slot 18, and then the stretcher auxiliary rod 11 can be moved away from or close to the first main support plate 5 until the stretcher auxiliary rod 11 is moved to the appropriate position, and then the threaded fastening rod 17 is rotated again to be inserted into the corresponding slot 18, at this time, the distance between the stretcher auxiliary rod 11 and the stretcher main rod 1 changes, and the total length of the shovel stretcher is adjusted to facilitate the use of the shovel stretcher for patients of different heights.
