A number of independently liftable and adjustable shelves 5 are equidistantly provided between the two vertical grooves 4, and a double-output shaft motor 6 is installed in the middle of the bottom of the shelf 5, and a lifting transmission structure is installed between the two ends of the bottom of the shelf 5 and the inside of the vertical grooves 4, and the two output ends of the double-output shaft motor 6 are rotatably connected to the two lifting transmission structures at both ends of the bottom of the shelf 5 respectively.

[0018] Two vertical tooth plates 7 are symmetrically fixedly installed inside the vertical groove 4. The lifting transmission structure includes a pair of fixed blocks 8, and a pair of fixed blocks 8 are symmetrically fixedly installed at the bottom of the layer plate 5. A rotating shaft 9 is rotatably installed between each pair of fixed blocks 8. Rolling gears 10 are fixedly installed at both ends of the rotating shaft 9. The two rolling gears 10 on the rotating shaft 9 are located on the opposite side of the pair of fixed blocks 8. The rolling gears 10 are meshed and connected with the vertical tooth plates 7, so that they can be effectively lifted and lowered; a worm gear 11 is fixedly installed in the middle of the rotating shaft 9, and the two output ends of the double-output shaft motor 6 are fixedly connected with an adjusting shaft 12, which passes through and is rotatably connected to the bottom of the layer plate 5. The end of the adjusting shaft 12 is fixedly connected with a worm segment 13, which is meshed and connected with the worm wheel 11, so that it can be effectively lifted and lowered;

[0019] Workers can place building materials on top of the layer plates 5 by standing on the ground, starting from the top layer plate 5 and moving downwards in sequence, and finally placing them on the placement base 1; when the building materials are placed, the two adjusting shafts 12 are rotated by starting the double-output shaft motor 6, and the rotation of the adjusting shaft 12 will drive the worm segment 13 to rotate, and the rotation of the worm segment 13 will drive the worm wheel 11 to rotate the rotating shaft 9, and the rotation of the rotating shaft 9 will drive the two rolling gears 10 at both ends thereof to rotate, and the rotation of the rolling gear 10 will roll upward on the surface of the vertical tooth plate 7 and drive the layer plates 5 to move upward; finally, several layer plates 5 are spread out and arranged at equal distances between the two side frame plates 2.

[0020] A plurality of pairs of cannulas 14 are fixedly installed at equal distances inside the vertical groove 4.
