A reciprocating-type variable-speed pedal structure for a scooter comprises a power press bar (2) movably connected to a scooter bracket (1) and a power press bar return mechanism (A) for enabling an end of the power press bar (2) to flex upward. The upper end of the power press bar (1) is movably connected with a moving pedal (5) by a shaft (4), thus dividing the moving pedal (5) into a moving pedal limiting end and a moving pedal labor-saving end. A movable connecting member (8) for limiting the movement range of the moving pedal (5) is provided between the front part of the moving pedal limiting end and the bracket (1). The pedal structure of the present invention is used for two-wheeled to four-wheeled scooters. The stepping mode is coincident with a human standing stepping posture, so it is easy for a person to exert a force smoothly. Meanwhile, the structure has a three-position variable-speed effect of low, middle and high speeds and a large output power. |
