Said timing mechanisms making hollow shaft engage are composed of two reduction gears. Each reduction gear is fitted on hollow shaft and consists of spur gears and ratchet mechanisms. Aforesaid output shaft is arranged inside hollow shafts aligned and engaged therewith via two ratchet mechanisms arranged inside hollow shafts. One of reduction gear gears is fitted rigidly on output shaft. Another reduction gear spur gear runs free on hollow shaft to drive it via ratchet mechanism.
