It is dynamic.
Please also refer to Fig. 4, when the first depressed part 71 of the first cam 70 is sticked in the second cam 80, the first cam 70 will
Cannot rotate, it is related second gear 60, first gear 50 and first rotating shaft 10 is also rotated, therefore first rotating shaft 10 is in
Lock-out state.Now, the second rotating shaft 20 can be rotated and be in unlocked state, therefore the second plate being connected with the second rotating shaft 20
Body can be pulled and be started rotation relative to the first plate body, make electronic installation become to raise by covering.
Referring again to Fig. 5, when the second rotating shaft 20 as shown in Figure 4 have rotated 180 degree, i.e., it is connected with the second rotating shaft 20
When second plate body is pulled and have rotated 180 degree relative to the first plate body and electronic installation is raised 180 degree, the band of the second rotating shaft 20
Dynamic second cam 80 also have rotated 180 degree, make the first depressed part of the second depressed part 81 of the second cam 80 and the first cam 70
71 is opposite, therefore the rotating shaft 20 of first rotating shaft 10 and second is in unlocked state.Now, the position that can design the second stopper 35 is come
The second convex portion of backstop 23 and limit the anglec of rotation of the second rotating shaft 20, though make the second rotating shaft 20 can not in unlocked state
Exceed 180 degree to continue rotation.First rotating shaft 10 is in unlocked state and can rotate, therefore is connected with first rotating shaft 10
The first plate body can be pulled and relative to the second plate body start rotation, electronic installation is further continued for further by raising 180 degree
Raise.
Referring again to Fig. 6, when first rotating shaft 10 as shown in Figure 5 starts to rotate, i.e., for being connected with first rotating shaft 10
One plate body pulled and relative to the second plate body start rotate and make electronic installation from raise 180 degree continue further raise when,
First gear 50 and second gear 60 start to rotate together with opposite clockwise, make the first cam 70 start to rotate, and cause
When second depressed part 81 of the second cam 80 is sticked in the first cam 70, and then the second rotating shaft 20 is set to rotate and be in locking
State.Now, the position that can design the first stopper 34 comes the first convex portion of backstop 13 and limits the anglec of rotation of first rotating shaft 10, makes
Untill first rotating shaft 10 may only continue rotation 180 degree, such first plate body will start rotation relative to the second plate body, make electronics
Device is further continued for raising to 360 degree by raising 180 degree.
Although the utility model is disclosed above in a preferred embodiment thereof, so it is not limited to the utility model, appoints
What those skilled in the art, not departing from spirit and scope of the present utility model, when a little change and retouching, therefore this can be made
The protection domain of utility model is defined when depending on appended as defined in claim.
