Auto/hand shift lever, the clutch will shift up and declutch the wormgear to engage the handwheel

柄，使离合器上移脱开蜗轮而与手轮接上（这时松开手柄，手柄将恢复到初始位置）即可手动操作，传动

Ifs use finger shape milling cutter or a dish of shape piece of milling cutter adopt single tooth dispart law cutting time, cans process straight teeth, skewed tooth, a garden of stud gear and bring groove double helical gear or worm gear, this moment was processed gear's dentiform then by cutting tool become shape.

若用指形铣刀或盘形片铣刀采用单齿分度法切削时，可加工直齿、斜齿、园柱齿轮及带槽人字齿轮或蜗轮，此时被加工齿轮的齿形则由刀具成形。

The SP receptor immunoreactivity positive material mainly distributed with a high dense linear appearance in the endangium.
