[0032] In some embodiments, as Figure 3 shown, an opening and closing assembly 3 is installed on the hoisting base 1. The opening and closing assembly 3 includes a bracket 31, a rotating shaft 32, a baffle 33 and a locking member 34. The bracket 31 is fixedly connected to the hoisting base 1. The rotating shaft 32 is rotatably connected to the bracket 31 through a bearing. The bottom end of the baffle 33 is fixedly connected to the rotating shaft 32. The locking member 34 is used to limit the rotation of the rotating shaft 32.

[0033] Furthermore, the bracket 31 is processed into a U shape. Both ends of the rotating shaft 32 extend out of the bracket 31. The baffle 33 rotates together with the rotating shaft 32.

After the overall mechanism is lifted to a suitable position through the lifting rings 213, rotate the positioning pin 343 in the arc-shaped plate 342. The positioning pin 343 is separated from the grooved wheel 341. Then, rotate the rotating shaft 32 in the bracket 31 to drive the baffle 33 to flip 180 degrees. Next, rotate the connecting rod 212 to separate it from the lifting base 1. Then, push the two side guard plates 211 to separate from the lifting base 1. Rotate the screw 273 through the knob. The screw 273 moves downward in the threaded cylinder 272. Furthermore, the clamping seat 274 drives the push rod 25 to move downward. The push rod 25 pulls the connecting rope 24 to move on the outer wall of the fixed pulley 23. Furthermore, the connecting rope 24 drives one end of the bottom plate 26 to tilt up. The tilted bottom plate 26 forms an inclined plane. Then, the building materials on the lifting base 1 are pushed down to complete the unloading work of the building materials.
