When it is necessary to increase the placing area, the electric push rod 41 is elongated to push the extension plate 42 to move outward, the connecting block 43 and the guard plate 44 on the upper surface of the extension plate 42 are synchronously moved, so as to expand the placing panel of the bottom plate 1. In addition, the auxiliary wheel 46 can play a role in auxiliary support after the extension plate 42 is extended, facilitating the extension of the extension plate 42 and dispersing the pressure when heavy building materials are placed. Since the interiors of the universal wheels 2 and the auxiliary wheel 46 are both provided with brake pads, the locking can be performed through the braking effect of the brake pads to prevent displacement during the placement of building materials.

[0025] The two groups of extension assemblies 4 are symmetrically arranged, and the two groups of protective plates 44 are arranged close to one side of the bottom plate 1 and are provided with anti-skid pads 5, which can increase the friction between the building materials and the extension plates 42 and prevent the building materials from sliding during transportation.

[0026] Each group of protective plates 44 is provided with a locking assembly 6 on one side, which comprises a latch rod 61 penetrating into the protective plate 44 and a plug 62 sleeved on the latch rod 61. The plug 62 is fixedly installed with a spring 63 on one side, and the spring 63 is provided with a latch head 64 at one end. The inside of the baffle 45 is provided with a latch cylinder 65, and the latch head 64 is embeddedly connected with the inside of the latch cylinder 65. The inside of the protective plate 44 is provided with a clamping groove 66, and the outer surface of the plug 62 is provided with a clamping block 67, which is embeddedly connected with the inside of the clamping groove 66. When it is necessary to prevent the building materials from falling, the two groups of protective plates 44 are rotated to one side of the building materials on the bottom plate 1, and then the latch head 64 is rotated and embedded into the latch cylinder 65 in the protective plate 44 through the latch rod 61, and at the same time, the clamping block 67 is also rotated into the clamping groove 66, so as to fix the clamping block 67. Therefore, the spring 63 on one side of the clamping block 67 always provides support force for the latch head 64, further increasing the protection of the protective plate 44. When disassembling, the latch rod 61 can be unlocked by counterclockwise rotation.

[0027] Each group of protective plates 44 is provided with a limiting column 7 on one side, and the outer surfaces of the two groups of limiting columns 7 are sleeved with elastic belts 71, which further improve the stability of transporting building materials.
