Pause point 10-4；The lower end 7-2 of pull rod 7 passes sequentially through the first pause point 10-1, the second pause point 10- in one-way circulation slot 10
2, third pause point 10-3 and the 4th pause point 10-4 makees rotation counterclockwise；First pause point 10-1 to the second pause point 10-2
Between be line channel 10-5, between the second pause point 10-2, third pause point 10-3 and the 4th pause point 10-4 be " ∧ " shape
Guide groove 10-6；4th pause point 10-4 between the first pause point 10-1 be arc guide groove 10-7.
By pressing handle 9 from the bottom to top, the lower end 7-2 of pull rod 7 is by the first pause point 10-1 along line channel 10-
5 to reaching the second pause point 10-2, and then extends on " ∧ " shape guide groove 10-6, lower end 7-2 pause third pause point 10-3
At position, at this point, lock tongue 8 is in targeting port 4-3, the vehicle body ironware that stretches is in an open state, can front and back adjustment chassis frame
Distance；After the distance of front and back chassis frame is adjusted, it is only necessary to which handle presses 9, and the lower end 7-2 of pull rod 7 is by third pause point
10-3 along " ∧ " shape guide groove 10-6 to reaching the 4th pause point 10-4, and then by arc guide groove 10-7 to reaching the first pause
Point 10-1, for engaging front and back chassis frame, closes the flexible ironware of its vehicle body at this point, lock tongue 8 is in outside targeting port 4-3
Shape, by a "ON" one "Off" of the lower end 7-2 of pull rod 7 in one-way circulation slot 10, so that the distance of adjustment chassis frame
It is more convenient, improve service efficiency.
The length of line channel 10-5 is consistent with the length of guide groove 4-2；Make being turned on or off for lock tongue 8 in this way
It is all more smooth, it ensure that safety in utilization.
The upper end of lock 4 is provided with the guide post 4-4 for position reset spring 6, and the length of guide post 4-4 is less than guiding
The length of slot 4-2；By the way that guide post 4-4 is arranged, it is possible to prevente effectively from 6 long-time of reset spring is using shifting later, shadow
The accuracy that the circulation is used from latch is rung, meanwhile, also extend service life.
