The utility model relates to a speed increasing and reducing mechanism for flexible axle driving rock driller transmitting dynamic force. A gear speed increasing mechanism which is composed of a big gear and a pinion gear is arranged between a gasoline engine or an output shaft of a motor and a flexible axle, and a clutch mechanism which is mainly composed of a clutch disc and a clutch block is arranged between an output shaft of the gasoline engine and the gear speed increasing mechanism. An overrunning clutch structure is arranged between the output shaft of the motor and the gear speed increasing mechanism, and a set of speed reducing mechanisms which are composed of small angular gears and big arced gears are arranged between the output of the flexible axle and the working portion of the rock drill. The utility model has the advantage of scientific and reasonable structural design.
