摘要（英）：

A supporting device includes an upper tube (10A), an inner tube (20A), a transmitting system (30A) and a shoe (40A). Said transmitting system (30A) is mounted on the top of the upper tube (10A). Said inner tube (20A) is cover-placed inside the upper tube (10A), the top of the inner tube (20A) is connected to the transmission (30A) and the bottom of that is connected to the shoe (40A). The transmitting system (30A) is mainly composed of at least one less teeth difference transmission (1A), a cone gear pair and a screw (6A). The less teeth difference transmission (1A) is connected to a cone gear (31A), and the cone gear (31A) is connected to the screw (6A).
