As shown in Figure 10, in the present embodiment, rotatable parts 600 (mechanical arm) are on perpendicular in rotary course, by it
600 center of gravity highest point of rotatable parts is set as base position 601 on running track, by two rotatable parts on its running track
600 center of gravity lowest points are set as first object position 602 and the second target position 603.In the present embodiment, by rotatable parts 600
The rotation angle of base position is set as 0 degree, rotation angle range be rotate clockwise 0~90 degree and rotate 0 counterclockwise~
90 degree.Judge conterclockwise direction of visual lines for the direction of the first support plate of face 501, it is seen that the present embodiment outer rotating part
600 (mechanical arms) whole rotary course.
As shown in Figure 10, when rotatable parts 600 are located at the reference position 601, the first rotating device 100 and the second rotating dress
It sets 200 all to remain stationary, scroll elastic component 300 is remained stationary.First fixture block 103, the second fixture block 104 are vertically arranged, and first
Turntable block 2032, the second turntable block 2042 are all located at 101 top of the first transmission shaft.
When the needs of rotatable parts 600 rotate counterclockwise to first object position 602 from base position 601, rotatable parts
600 center of gravity moves from high to low, and driving device 700 (motor) drives rotatable parts 600 (mechanical arm) to rotate counterclockwise,
Transmission device 400 is also driven generation rotation counterclockwise.At this point, the first turntable block 2032 of the first turntable 203 is stuck in transmission
In first arc bayonet 4011 of plate 401, therefore it will drive the second rotating device 200 and rotate counterclockwise, when rotatable parts 600 arrive
When up to first object position 602, rotational angle is 90 degree.In this course, the second turntable block 2042 is in the second arc card
Sliding in mouthfuls 5022, it is ensured that the second turntable 204 can with the first turntable 203 synchronize rotate.In this course, the first card
For block 103 not by any resistance in the first limit hole 403, the first rotating device 100 is totally stationary motionless.Due to scroll
The inner end of elastic component 300 is fixedly attached to the first rotating device 100, and outer end is fixedly attached to the second rotating device 200, because
