Moreover, please consult Figure 1B and Fig. 1 C simultaneously, first convergence part 1042 of first actuating component 104 comprises through hole 10420, firm banking 100 comprises the pillar 1000 by through hole 10420, through hole 10420 is connected rotationally in pillar 1000, and first actuating component 104 is connected rotationally in firm banking 100.First end 1040 of first actuating component 104 comprises teat 10400, the first ends 1040 and slides on first slide rail 1020 by teat 10400.
By said elements and between annexation as can be known lens moving apparatus 10 mode of motion that promotes camera lenses 12 be: when the relative first turning axle FR rotation of first actuating component 104, first end 1040 promotes lens bearing seat 102 and moves along the first direction FD that is different from the first bearing of trend FE, just, camera lens 12 moves along first direction FD.
In addition, lens moving apparatus 10 of the present invention also comprises the adjustment member 108 shown in Figure 1B, allows the user make first actuating component 104 produce above-mentioned motion by adjusting member 108.Adjust member 108 and comprise adjustment part 1080 and connecting portion 1082, connecting portion 1082 has through hole 10822 and pillar 10824, and adjustment part 1080 is connected in firm banking 100, and adjustment part 1080 is connected adjustably in connecting portion 1082.First actuating component 104 comprises second end 1044, has through hole 10440 on second end 1044, pillar 10824 by connecting portion 1082 passes the through hole 10440 on second end 1044 of the through hole 10822 of connecting portion 1082 and first actuating component 104, connecting portion 1082 is connected rotationally with second end 1044, rotates with respect to the first turning axle FR in order to promote first actuating component 104.What need supplementary notes is, through hole 10440 on second end 1044 of the through hole 10822 of connecting portion 1082 and first actuating component 104 can be an elliptical aperture, or the aperture is greater than the hole of the Any shape of pillar 10824 diameters, pillar 10824 can be moved in the through hole 10440 of the through hole 10822 of adjusting member 108 or first actuating component 104, so that when the connecting portion 1082 of adjusting member 108 promotes second end 1044 of first actuating component 104, second end 1044 can rotate and not can with connecting portion 1082 mutual strangulations.Wherein, first convergence part 1042 is between first end 1040 and second end 1044.Connecting portion 1082 promotes second end 1044 of first actuating component 104 along second direction SD, and second direction SD is roughly parallel to first direction FD, and is approximately perpendicular to the first bearing of trend FE.Thus, first actuating component 104 is adjusted the end that member 108 promotes first actuating component 104 just as a lever, makes the other end oppositely promote lens bearing seat 102.
