The principle of a pair of meshed gears cutting tea is shown in Figure 3-4. The motor drives the positive and negative rotation of the gear, drives the blade to move in the opposite direction through the connecting rod, and the blade is fixed at the lower end of the connecting rod, so as to complete the action of picking tea. The advantage of this structure is that the transverse dimension is compact, and it is not easy to disturb the tea around the target fresh leaves. The disadvantage is that the gear clearance will affect the closure of the blades to a certain extent. Moreover, the opening and closing angle of the gear is small, that is, the fixed teeth are engaged for a long time, which shortens the service life of the gear.<br>
