Wherein the lower mould lifting seat drive assembly is the common structure on the market, belongs to prior art, also does not involve the innovation point of the application, so it will not be repeated here. The first and second single point formula transmission tooth in the application means that the two transmission teeth can only be engaged in transmission by rotating to a single adaptive angle.
