PURPOSE: A gear ejection device is provided to work quickly by discharging a gear if a rotary shaft is simply pressed by rotating a spiral shaft. CONSTITUTION: A gear ejection device comprises a supporting bar(10), multiple arm members(20,30), locking members(22,32), and a spiral shaft(40). The supporting bar has a spiral hole(11) in the middle. The arm members move according to the supporting bar. The locking members are installed in the end of the arm members. Projected portions are formed in the locking member in an inward direction. The spiral shaft is coupled to the spiral hole and longitudinally moves at right angle to the support bar. |
