[0025] ​In the process of working, this splicing device is an L-shaped aluminum profile structure, which is formed by heating aluminum ingots to a certain temperature, using a mold designed in advance, and extruding with related equipment. The appearance is a whole, and the structure is made of full aluminum material. The aluminum profile structure device is composed of a horizontal plate 501 and a vertical plate 502, which form a right angle, and the inner and outer corners are rounded.
