5. The portable electronic device as claimed in claim 1 , wherein the top cover comprises a first indentation and a first concavity, wherein the first indentation is vertical and adjacent to the first concavity.

6. The portable electronic device as claimed in claim 5 , wherein the bottom cover comprises a second indentation and a second concavity, wherein the second indentation is vertical and adjacent to the second concavity, the first concavity corresponds to the second concavity.

7. The portable electronic device as claimed in claim 6 , wherein the first concavity comprises a first hook and the second concavity comprises a second hook, the first hook is opposite the corresponding position of the second hook.

8. The portable electronic device as claimed in claim 7 , wherein the insulating portion comprises:

a third hook;

a fourth hook disposed opposite the corresponding position of the third hook; and

a protrusion disposed between the third hook and the fourth hook, wherein when the data communication plug is in the first position, the first hook is engaged with the third hook and the second hook is engaged with the fourth hook, the protrusion is engaged with the first indentation and the second indentation, and the metallic plug is received in the body.

9. The portable electronic device as claimed in claim 8 , wherein the top cover further comprises a top sliding portion and the bottom cover further comprises a bottom sliding portion, the top sliding portion is disposed in the first indentation and the bottom sliding portion is disposed in the second indentation.

10. The portable electronic device as claimed in claim 9 , wherein the top sliding portion and the bottom sliding portion comprise a plurality of correspondingly disposed sliders.

11. The portable electronic device as claimed in claim 9 , wherein the top cover further comprises a first limiting portion and the bottom cover comprises a second limiting portion, the first limiting portion corresponds to the second limiting portion.

12. The portable electronic device as claimed in claim 11 , wherein the first limiting portion and the second limiting portion are respectively connected to the top sliding portion and the bottom sliding portion.

13. The portable electronic device as claimed in claim 11 , wherein the first limiting portion and the second limiting portion further comprises a plurality of limiting elements, each limiting element is disposed corresponding to each other.

14. A portable electronic device, comprising:

a body;

a circuit board disposed in the body; and

a data communication plug comprising a metallic plug and an insulating portion connecting with the metallic plug, wherein the data communication plug is detachably disposed in the body in a manner such that the data communication plug is positioned between a first position when the plug is disposed inside the body and a second position when the metallic plug is disposed inside the body;

wherein the insulating portion comprises a first connector and the circuit board comprises a second connector, the first connector is connected to the second connector when the data communication plug is in the second position, and the first connector is not connected to the second connector when the data communication plug is in the first position.

15. A portable electronic device, comprising:

a body comprising a first hook and a second hook;

a circuit board disposed in the body; and

a data communication plug comprising a metallic plug and an insulating portion connecting with the metallic plug, wherein the data communication plug is detachably disposed in the body in a manner such that the data communication plug is positioned between a first position when the metallic plug disposed inside the body and a second position when the metallic plug is disposed outside the body;

wherein the insulating portion comprises:

a third hook;

a fourth hook disposed opposite the corresponding position of the third hook; and wherein the first hook is engaged with the third hook and the second hook is engaged with the fourth hook when the data communication plug is in the first position, and the first hook is engaged with the fourth hook and the second hook is engaged with the third hook when the data communication plug is in the second position.
