Circuit board with handles

1. A circuit board comprising:

a main body defining at least one through hole;

at least one handle, one end of each of the at least one handle defining a positioning portion; and

at least one connecting element;

wherein the positioning portion of each of the at least one handle extends through a corresponding one of the at least one through hole and is engaged with one of the at least one connecting elements, the positioning portion of each of the at least one handle defines an internally threaded blind hole, each of the at least connecting element is a screw that fits the blind hole, and the positioning portion extends through the corresponding through hole and the corresponding screw is screwed into the positioning portion, a supporting element extends from the positioning portion, a size of the positioning portion of each of the at least one handle is smaller than a size of the supporting element, a step is formed between the positioning portion and the supporting element, and the step abut a surface of the main body when the handle is assembled to the main body through the corresponding through hole, and, the positioning portion and the corresponding through hole are double-D shaped to prevent rotation of the handle.

2. The circuit board as recited in claim 1 , wherein a top of each of the at least one handle is curved.

3. The circuit board as recited in claim 1 , wherein the number of the at least one handle is two.

4. The circuit board as recited in claim 3 , wherein the two handles are fixed in a diagonal line of the body.

5. The circuit board as recited in claim 1 , wherein each of the at least one handle is “T” shaped.
