Position pin 8, lock banking stop 4, swing pawl 10 rotate clockwise, while the free end of spacing torsional spring 19 departs from handrail installing plate
1 limiting slot.After 36 ° rotationally clockwise of handrail, lock banking stop 4 turns to extreme position, the lock banking stop that lock banking stop 4 welds
The one end for the annular groove 22 that spacer pin 21 is moved on fixed pawl 3 and stop operating.
Handrail continues 94 ° rotationally clockwise, and in rotation process, the position of lock banking stop 4 is fixed, swings pawl
10 rotate with handrail, and the part for swinging the front end of pawl 10 is against slide downward on the outer edge of lock banking stop 4；
When total rotational angle is 130 °, that is, reach lowest gear, as shown in Figure 1；The front end for swinging pawl 10 departs from lock
Limited step 4, the swing pawl pockets 11 swung on pawl 10 are engaged with fixed pawl latch 5, and handrail is locked at lowest gear, this
When spacer pin 8 contacted with the first block 6 on fixed pawl 3, continue to rotate down so as to limit handrail；Axis spring is hinged at this time
12 be compressive state, and reverse push movable pendulum pawl 10 makes to engage with fixed pawl latch 5 firm.
Reach lowest gear, after as shown in Figure 1, handrail is every upward, that is, rotates counterclockwise 12 °, that is, adjust to a higher
Gear when；Pawl 10 is swung also to be rotated up with lock banking stop 4；The swing pawl pockets 11 on pawl 10 are swung just with fixing spine
Pawl latch 5 is engaged on the gear of a higher.
As shown in Fig. 2, after being rotated up 24 ° for handrail, reach armrest during highest gear.Pawl 10 is swung at this time
A front end part be still against on the outer edge of lock banking stop 4, hinged axis spring 12 is compressive state, reverse push movable pendulum pawl
10 make to engage with fixed pawl latch 5 it is firm.
Pawl 10 is swung in upward movement, while promotes lock banking stop 104 to be rotated up.Handrail is rotated up more than 24 °,
That is after more than three gears, swing pawl 10 departs from fixed pawl 3 no longer to be engaged, after handrail rotates more than 36 °, lock banking stop 4
Stop operating after moving to extreme position, the front end of swing pawl 10 contacts with each other again with 4 outer contour of lock banking stop to be propped up；
After lowest gear is rotated up more than 36 °, as shown in Figure 3, Figure 4, continue up outside rotary handle meeting lock banking stop 4
Profile make it that swinging pawl 10 tilts, and continues up rotation along the outer contour of lock banking stop 4, at this time hingedly axis spring 12 from
Power.
After lowest gear rotates up 130 °, spacer pin 8 is propped up with 7 phase of the second block on fixed pawl 3, so that nothing
Method continues up rotation, and handrail is to be back to collapsed state at this time.
Handrail could be rotated up to other gears after collapsed state turns to lowest gear from lowest gear, without
The gear of other higher positions can be pivotally lowered into collapsed state.
Above-described embodiment of the utility model is not the restriction to scope of protection of the utility model, the reality of the utility model
Mode not limited to this is applied, all this kind the above according to the present utility model, according to the ordinary technical knowledge of this area and used
With means, under the premise of the above-mentioned basic fundamental thought of the utility model is not departed from, the utility model said structure is made its
The modification, replacement or change of its diversified forms, should all fall within the scope of protection of the utility model.
