Working principle
1, the stage is tightened
Fixed pedestal 1 is in place first, and drive shaft 5-1 is sequentially inserted into outer cover 5-3, is drivingly connected in mouth 5-2, rotation
Turn drive shaft 5-1 certain angle, so that snib 5-1-2 misplaces with the jack 5-3-1 covered outside, to prevent drive shaft from driving
It falls off at connector.
Rotating clockwise drive shaft 5-1 by external force drives driving shaft 3-1 and first gear 3-2 to rotate clockwise；First
The gear 3-2 gear teeth are engaged second gear 3-4；Second gear 3-4 is rotated counterclockwise and along screw thread 3-5 to the first friction plate 3-6
Direction is mobile, and subsequent second gear 3-4 is successively by the first friction plate 3-6, ratchet 3-7, the second friction plate 3-8, third gear 3-9
It compresses, under the drive of second gear 3-4, five element coaxial rotations；Third gear 3-9 is engaged the 4th gear 2-2, third tooth
Wheel 3-9, which is rotated counterclockwise, drives the 4th gear 2-2 to rotate clockwise；Since the 4th gear 2-2 and reel 2-1 are integrated device,
Therefore reel 12-1 is rotated clockwise, and completes tightening；Since check pawl 4-1 is not at this time by L v notch v on columnar stays pedestal
The limitation of 4-2-1-1, check pawl 4-1 can be slipped over from ratchet 3-7 outer gear.
2, stop the driving stage:
Stop driving drive shaft 5-1, under the action of cable, reel 2-1 is rotated counterclockwise reel, the 4th gear 2-2
It rotates counterclockwise, then third gear 3-9 is driven to rotate clockwise；According to the self-lock mechanism of screw thread, the first friction plate 3- at this time
6, ratchet 3-7, the second friction plate 3-8, third gear 3-9 are still closely connected, therefore third gear 3-9 is rotated clockwise, and are driven
Ratchet 3-7 is rotated clockwise；Since its tail portion is scarce by L shape on columnar stays pedestal during rotating down by check pawl 4-1
The limitation of mouth 4-2-1-1 side wall, under the action of check pawl 4-1, ratchet 3-7, which is rotated clockwise, to be obstructed, to prevent reel
2-1 is rotated counterclockwise, and realizes that this electronic tightening line apparatus is self-locking.
3, the stage is discharged
When release, drive shaft 5-1 certain angle is reversely rotated, so that snib 5-1-2 and the jack 5-3-1 covered outside are wrong
Position, to prevent drive shaft from falling off from being drivingly connected mouth；Drive shaft 5-1 drives driving shaft 3-1 and first gear 3-2 counterclockwise
Rotation, the first gear 3-2 gear teeth are engaged second gear 3-4, and second gear 3-4 is rotated clockwise under first gear 3-2 drive
And moved along screw thread 3-5 to the opposite direction of the first friction plate 3-6, subsequent second gear 3-4 successively by the first friction plate 3-6,
Ratchet 3-7, the second friction plate 3-8, occurs gap between third gear 3-9, release is completed in self-locking function failure.
In addition, second gear 3-4 and first driven shaft 3-3 can be consolidated by parts such as screws if necessary to accelerated release in vitro
Get up calmly, when being driven in the reverse direction, second gear 3-4 is rotated coaxially with first driven shaft 3-3, and third gear 3-9 is driven to turn clockwise
It is dynamic, so that the 4th gear 2-2 and reel 2-1 are rotated counterclockwise, thus accelerated release in vitro.
