Specific implementation mode
Referring to Fig. 1 and Fig. 4, a kind of driving device of developing cell of the utility model, including gear mounting plate 1, installation
Driving gear 2 in gear mounting plate 1, the power sub 3 for connect with driving gear 2 and driving the driving rotation of gear 2 and
It is retractably installed at the driving head 5 of printer, the driving head 5 can engage with power sub 3 and drive power sub 3
Rotation, the gear mounting plate 1 include gear baffle 11 and the gear protecting cover 12 mounted on 11 outside of gear baffle, the driving
Gear 2 is mounted between gear baffle 11 and gear protecting cover 12, and the power sub 3 is stretched out outside gear protecting cover 12.
With further reference to Fig. 2 and Fig. 3,3 front center position of the power sub is equipped with the locating slot aligned with driving head 5
31, the internal diameter of the locating slot 31 is gradually reduced from front to back, facilitates driving head 5 and 3 locating engagement of power sub and driving
First 5 rapid disengaging power subs 3,3 front edge of the power sub is equipped with a pair of symmetrical tooth engaged 32, the occlusion
