Since it is driven by one driving motor 5, it occupies little free space, and can also ensure the important effect of the furnace door 3, thereby ensuring the reliability of the compression and sealing of the furnace door 3. Due to the adoption of the above structure, the utility model has the advantages of simple structure, good compression effect, high compression efficiency, small space occupation, and low maintenance cost.
