Threaded hole I (50) and threaded hole II (53) are respectively equipped on fixture nut (42) and clamp nut (45)；
Bend pipe (41) is fixed on via hole siding (51) with fixture nut (42), uses sealing ring between bend pipe (41) and via hole siding
(43) it seals；
There is the step (52) of a limitation pressing plate I (44) in bend pipe (41), sealing plate (46) is extruded in pressing plate I (44) and pressing plate
Between II (54), clamp nut (45) is pressed on pressing plate II (54) after being screwed into bend pipe (41), and sealing plate (46) is wrapped in bend pipe
(41) on inner cable (48), full-filling silica gel (47) is sealed between cable；Clamp nut (45) are tightened, before making clamp nut (45)
Pressing plate II (54) squeezes forward sealing plate (46)；Sealing plate (46) clogs the sky between bend pipe (41) and cable after being extruded
Gap.
