Between a connecting rod move ratchet（46）Rope can be pulled out by disengaging it from hook tooth；Reclaim friction plate（6）With clamping plate（5）
During combination, drum shaft is rotated by spanner（42）Drive roller（43）Rotation makes rope be wrapped in roller（43）On, rope closing mistake
Ratchet in journey（46）In ratchet（45）The back of tooth on slip over, after rope closing, ratchet（46）Embedded ratchet（45）Tooth in prevent
Roller（43）Reverse, prevent rope from from roller（43）Upper pull-out, reach locking purpose；
The spring fastening（1）Including bearing nut（8）, support spring（9）, base-plate（10）, lead screw（11）And back-up ring
（12）Component, the back-up ring（12）Base-plate with being disposed with some through holes（10）Welding, back-up ring（12）Internal diameter is equal to bearing
Spring（9）External diameter, support spring（9）One end, which polishes, is arranged at back-up ring（12）Inscribe section, and and base-plate（10）Contact,
Support spring（9）The other end is socketed stepped bearing nut（8）, bearing nut（8）Upper outer end is to be tightened just for spanner
Hexagon, lead screw（11）Through base-plate（10）Through hole and bearing nut（8）Threaded connection, base-plate（10）Welding
In bottom of car；Work as lead screw（11）During by pulling force, support spring（9）Compressed, play buffer protection function, be unlikely to branch
Seat bottom plate（10）Draw bad.
