The sizes of these round holes 703 and square holes 704 are much smaller than the size of the hexagonal hole 401 on the loading plate 4. When small workpieces are placed on the bottom net 701, they cannot pass through the round holes 703 and square holes 704 due to their small diameters, effectively preventing the small workpieces from falling off the bottom net. Moreover, the blocking net 705 plays a blocking role to prevent small workpieces from falling off the side of the loading plate 4, ensuring the stability and safety of small workpieces during heat treatment and hoisting.
