Circumferential lever booster and transmission means thereof

A circumferential lever booster, comprising an acting force input mechanism, a circumferential lever boosting mechanism, a boost output mechanism and a machine body shell, wherein:

• the acting force input mechanism is provided with an input transmission part that is fixedly connected to an input eccentric wheel;
• the input eccentric wheel is positioned about a central axis of a machine body, and is fixedly connected to the machine body shell by means of a first bearing;
• the circumferential lever boosting mechanism is provided with a lever arm group, and the lever arm group comprises a plurality of lever arms uniformly distributed in a circumferential direction;
• a circumferential surface formed at one end of the lever arm group is movably connected to a second bearing fixedly connected to the input eccentric wheel about an eccentric axis of the input eccentric wheel, a circumferential surface formed at another end of the lever arm group is movably supported with a circumferential support seat;
• or, the circumferential surface formed at the one end of the lever arm group is movably supported with the second bearing fixedly connected to the input eccentric wheel about the eccentric axis of the input eccentric wheel, the circumferential surface formed at the other end of the lever arm group is movably connected to the circumferential support seat;
• the circumferential support seat is positioned about the central axis of the machine body, and is fixedly connected to the machine body shell, and a circumferential surface formed at a loading force end of the lever arm group is movably connected to a third bearing fixedly connected to an output eccentric wheel about an eccentric axis of the output eccentric wheel;
• the boost output mechanism is provided with an output transmission part which is fixedly connected to the output eccentric wheel, and the output eccentric wheel is positioned about the central axis of the machine body, and is fixedly connected to the machine body shell by means of a fourth bearing.
