[0017] In order to make the purpose, technical scheme and beneficial effect of the utility model more clear, the preferred embodiment of the utility model will be explained in detail below in combination with the drawings, so as to facilitate the understanding of the technical personnel. EMBODIMENT

[0018] As Figure 1 shown, an adjustable backfill elevation control device includes a base plate 1, a threaded sleeve 2, a screw rod 3, an adjusting disc 4, a hook 5, a winding disc 6, the base plate 1 has two, the top of the two base plates 1 is provided with a threaded sleeve 2 respectively, each threaded sleeve 2 is installed by a screw rod 3 in a threaded connection manner, one of the screw rods 3 is installed with an adjusting disc 4 in a threaded connection manner, the top edge of the adjusting disc 4 is uniformly provided with a hook 5, the other screw rod 3 is installed with a winding disc 6 winding the elevation line in a threaded connection manner, the pulling end of the elevation line is provided with a coil that can be hung on the hook 5. By placing the base plate 1 on the ground, then adjusting the adjusting disc 4 and the winding disc 6 on the two screw rods 3 to the corresponding height, the elevation line wound on the winding disc 6 is pulled out and sleeved on the hook 5 of the adjusting disc 4, at this time, the position of the elevation line is the elevation of the backfill. The utility model discloses two screw rods, and the height adjustment of the adjusting disc and the winding disc on the two screw rods is realized in a threaded connection manner, so that the height adjustment of the elevation line in the winding disc can adapt to the demand of different backfill elevations, the adjustment of the elevation positioning rod is more convenient and fast, and the inconvenience caused by manual line drawing is reduced.

[0019] In the utility model, as Figure 2 shown, the winding disc 6 includes a shell 6-1, a spring reel 6-2, a screw sleeve 6-3, an elevation line locking block 6-4 and an elevation line 6-5, the shell 6-1 has a through hole in the middle, the through hole is installed with a screw sleeve 6-3 in a threaded connection manner with the screw rod 3, the outer wall of the screw sleeve 6-3 is installed with the spring reel 6-2, one end of the elevation line 6-5 is fixed on the spring reel 6-2, the elevation line 6-5 is wound on the outer wall of the spring reel 6-2, the spring reel 6-2 is provided with an elevation line 6-5 pulling outlet, and the pulling outlet is provided with the elevation line locking block 6-4. The winding principle of the elevation line 6-5 of the winding disc 6 is consistent with the structural principle of a tape measure, so that when the elevation line 6-5 is pulled out to a corresponding length to mark the elevation, the length of the pulled-out elevation line 6-5 can be locked by the elevation line locking block 6-4, the whole line keeps straight after the end of the elevation line 6-5 is hung on the hook 5, and the determination of the elevation position is avoided to be affected due to drooping.

[0020] In the utility model, as Figure 3 shown, the base plate 1 includes a left connecting block 1-1, a right connecting block 1-2, a fixed block 1-3 and a rotating shaft 1-4, the fixed block 1-3 is used for fixing the threaded sleeve 2, the front and back sides of the fixed block 1-3 are respectively installed with two rotating shafts 1-4, the left connecting block 1-1 and the right connecting block 1-2 are respectively rotatably installed on a corresponding pair of rotating shafts 1-4, and the left connecting block 1-1 and the right connecting block 1-2 are in Figure 3The distance between the middle parts in the shown expanded state is less than the diameter of the threaded sleeve 2, so when the left connecting block 1-1 and the right connecting block 1-2 are expanded, the restriction of the threaded sleeve 2 can ensure that the base plate 1 and the threaded sleeve 2 form a positive integral structure and are stably placed on the ground; after the backfill soil is filled to the elevation position, the entire base plate 1 and the threaded sleeve 2 can be pulled out from the figure by the handheld screw rod 3 to form a positive whole, at this time, due to the movement of the threaded sleeve 2 to the outside of the soil, and the left connecting block 1-1 and the right connecting block 1-2 are affected by the soil above and their own gravity, in the process of pulling out, the left connecting block 1-1 and the right connecting block 1-2 gradually become as shown in Figure 4 , so that the problem of difficult pulling out of the left connecting block 1-1 and the right connecting block 1-2 in the process of pulling out can be avoided.
