As shown in Figure 8 A to 8 D, under a normal condition, when foregoing second rail 30, (Fig. 8 A to Fig. 8 D only illustrate the actuating
Part 40 represents moving position of foregoing second rail 30 with respect to first rail 26) longitudinally relative first rail 26 from one fold position
In putting towards first direction D1 toward the movable displacement process of an extended position, the travelling carriage 36 is with the second rail (actuated piece 40)
Activity displacement and relative second rail (actuated piece 40) keep differentially (differentially) slide.For example, when
When second rail (actuated piece 40) is toward first direction D1 activity displacement one strokes, the travelling carriage 36 is synchronous and accurately covered
The stroke (for example, stroke of half) of the special ratios of second rail (actuated piece 40), that is, under this normal condition, the difference
The position of the dynamic correction mechanism 34 not differential displacement to the travelling carriage 36 is modified.When foregoing second rail 30 (actuated piece 40)
In from stowed position towards first direction D1 toward the movable displacement process of extended position, the actuated piece 40 can push against the actuator 44
Contact site 58 and drive the actuator 44 to be rotated toward direction counterclockwise, the teeth portion 56 of the actuator 44 is provided strength and interlock
The rack 50 of the push piece 42, the push piece 42 is movable (that is, the push piece 42 is movably connected with the actuator 44) accordingly, so as to make
The relative pedestal 46 of the push piece 42 is towards first direction D1 activities displacement (such as Fig. 8 B, Fig. 8 C), until the actuated piece 40 crosses the work
After the contact site 58 of moving part 44, the push piece 42 is discharged elastic force by the first stretch section 62 of aforementioned elastic parts 60, and the push piece 42 can
Automatic returning is to the default location (such as Fig. 8 D).

During first rail 26 is from stowed position towards first direction D1 toward the displacement process of the extended position, the actuated piece 40 can push against
The contact site 58 of the actuator 44 and drive the actuator 44 to be rotated toward direction counterclockwise, put forward the teeth portion 56 of the actuator 44
Force amount interlocks the rack 50 of the push piece 42, thus the push piece 42 be driven and the relative pedestal 46 and first rail 26 from acquiescence
Position (such as Figure 11 A) is towards first direction D1 activities displacement (such as Figure 11 B, Figure 11 C).Wherein, due to the travelling carriage 36 with respect to this
The position of the activity displacement of two rails (actuated piece 40) is wrong (or nonideal), and being during the 42 activity displacement of push piece can
Touch the travelling carriage 36, and the travelling carriage 36 drives to be moved to being capable of normally relative second rail (actuated piece 40) accordingly
An ideal position (such as Figure 11 C) (that is, the position of the differential displacement of the differential correction mechanism 34 to the travelling carriage 36 of differential displacement
Put and be modified), it can so complete to correct deviation of the travelling carriage 36 with respect to the differential displacement of the second rail (actuated piece 40),
The travelling carriage 36 is set again to keep normal differential displacement with respect to the second rail (actuated piece 40).On the other hand, until
After the actuated piece 40 crosses the contact site 58 of the actuator 44, the push piece 42 is discharged by the first stretch section 62 of aforementioned elastic parts 60
Elastic force, the push piece 42 can automatic returning to the default location (such as Figure 11 D).
