Electric case, has output cylinder whose diameter is adapted to diameter of threaded rod, where diameter of intermediate cylinder is greater than diameter of threaded rod that is provided between roller and output cylinder

摘要

The case (100) has a portion i.e. tank (102), comprising a bored barrel (112) pierced with a hole (114). Another portion i.e. lid (104), includes another hole (115) provided coaxially relative to the former hole. The latter hole comprises an input cylinder (116). Diameter of an output cylinder (120) is adapted to diameter of a threaded rod (110), where the diameter of the output cylinder is greater than diameter of a smooth rod (111). Diameter of an intermediate cylinder (118) is greater than the diameter of the threaded rod that is provided between a roller and the output cylinder.
