 wherein, the base-plate axis, the connection plate axis, the first axis and the second axis are parallel with one another, such that the base-plate body, the connection plate body, the first supporting plate and the second supporting plate are connected to form a ring-shaped body; 
 also, the base-plate body and the connection plate body are an inner-layer plate set, and the first supporting plate and the second supporting plate are an outer-layer plate set; a total length of the inner-layer plate set is substantially equal to a total length of the outer-layer plate set, and a length of the connection plate body is smaller than a length of the base-plate body, such that the connection plate body is able to be folded by pivoting on the connection plate axis so as to selectively be located at a corresponding position; 
 under an unfolded status, the connection plate body is located on the housing, and the outer-layer plate set is parallel to and covers the inner-layer plate set opposite to other side of the housing; and 
 under a folded status, the connection plate body is located on the base-plate body and opposite to the other side of the housing, such that the first supporting plate and the second supporting plate are tilted toward an outside to provide a supporting effect. 
 
     
     
       2. The apparatus according to  claim 1 , wherein a V-shaped right lateral side is matched by a first right side of the first supporting plate and a second right side of the second supporting plate. 
     
     
       3. The apparatus according to  claim 2 , wherein a V-shaped left lateral side which is opposite to the V-shaped right lateral side is matched by a first left side of the first supporting plate and a second left side of the second supporting plate. 
     
     
       4. The apparatus according to  claim 2 , wherein a slope of the first right side is equal to, greater than, or smaller than a slope of the first left side. 
     
     
       5. The apparatus according to  claim 1 ,  claim 2  or  claim 3 , wherein the connection plate body is selectively located at the corresponding position of the housing by a magnetic force. 
     
     
       6. The apparatus according to  claim 5 , wherein the housing is formed with an accommodating slot, and the base-plate body is disposed at the accommodating slot; under the unfolded status, the accommodating slot accommodates the base-plate body, the connection plate body, the first supporting plate and the second supporting plate. 
     
     
       7. The apparatus according to  claim 6 , wherein a length of the first supporting plate is substantially equal to a length of the second supporting plate, and the length of the connection plate body is substantially equal to 30-70% of a total length of the first supporting plate. 
     
     
       8. The apparatus according to  claim 7 , wherein the connection plate body is composed of a permanent magnet. 
     
     
       9. The apparatus according to  claim 7 , wherein the base-plate body, the first supporting plate and a second supporting plate are made of a metal, plastic or rubber material. 
     
     
       10. The apparatus according to claim 2, wherein the connection plate body is selectively located at the corresponding position of the housing by a magnetic force. 
     
     
       11. The apparatus according to claim 3, wherein the connection plate body is selectively located at the corresponding position of the housing by a magnetic force. 
     
     
       12. The apparatus according to claim 10, wherein the housing is formed with an accommodating slot, and the base-plate body is disposed at the accommodating slot; under the unfolded status, the accommodating slot accommodates the base-plate body, the connection plate body, the first supporting plate and the second supporting plate. 
     
     
       13. The apparatus according to claim 11, wherein the housing is formed with an accommodating slot, and the base-plate body is disposed at the accommodating slot; under the unfolded status, the accommodating slot accommodates the base-plate body, the connection plate body, the first supporting plate and the second supporting plate. 
     
     
       14. The apparatus according to claim 12, wherein a length of the first supporting plate is substantially equal to a length of the second supporting plate, and the length of the connection plate body is substantially equal to 30-70% of a total length of the first supporting plate.
