1. A portable electronic device, comprising: a torsion spring assembly having a roller and a torsion spring body, wherein the torsion spring body has a first coil part, a second coil part, a first extension part and a second extension part, the first coil part is connected to the second coil part, t
1. A portable electronic device, comprising: a torsion spring assembly having a roller and a torsion spring body, wherein the torsion spring body has a first coil part, a second coil part, a first extension part and a second extension part, the first coil part is connected to the second coil part, the first extension part is extended to one end of the first coil part, which is away from a junction of the first coil part and the second coil part, the second extension part is extended to one end of the second coil part, which is away from the connection of the first coil part and the second coil part, a winding direction of the first coil part is perpendicular to a winding direction of the second coil part, and the roller is connected to the first extension part; andan electronic device having a host unit and a display unit, wherein the first coil part and the first extension part are located at the host unit, the second coil part and the second extension part are located at the display unit, the host has a sliding groove disposed at one side of the host unit, the display unit has a fastener unit disposed corresponding to the sliding groove, the roller rolls within the host unit, and the second extension part is against the display unit;when the fastener element is connected to the sliding groove, the display unit is slidable relative to the host unit between a first position and a second position, and when the fastener element is departed from the sliding groove, the second extension part of the torsion spring body turns the display unit with an angle. 2. The portable electronic device of claim 1, wherein the torsion spring assembly further comprises a fixed base having a first fixed arm and a second fixed arm, the first coil part is wound around the first fixed arm, and the second coil part is wound around the second fixed arm. 3. The portable electronic device of claim 2, wherein an extension direction of the first fixed arm of the fixed base is perpendicular to an extension direction of the second fixed arm, the extension direction of the first fixed arm is the same as the winding direction of the first coil part, and the extension direction of the second fixed arm is the same as the winding direction of the second coil part. 4. The portable electronic device of claim 2, wherein the fixed base has a connection part, one end of the connection part is connected to the first fixed arm, and another end of the connection part is connected to the second fixed arm. 5. The portable electronic device of claim 1, wherein the first coil part is wound along a first winding axis and the second coil part is wound along a second winding axis. 6. The portable electronic device of claim 1, wherein the first extension part is extended to one end of the first coil part, which is away from a junction of the first coil part and the second coil part. 7. The portable electronic device of claim 1, wherein the second extension part is extended to one end of the second coil part, which is away from a junction of the first coil part and the second coil part. 8. The portable electronic device of claim 5, wherein the first extension part has a first restoring force and the second extension part has a second restoring force after slewed respectively by a first force and a second force, and a direction of the first restoring force is perpendicular to a direction of the second restoring force. 9. The portable electronic device of claim 8, wherein the first force makes the first extension part wound around the first winding axis, and the second force makes the second extension part wound around the second winding axis. 10. The portable electronic device of claim 8, wherein the second restoring force is released when the fastener element departs from the sliding groove, so that the second extension part turns the display unit with the angle. 11. The portable electronic device of claim 1, wherein the host unit further has a first housing and a second housing disposed opposite to each other. 12. The portable electronic device of claim 2, wherein the host unit further has a first housing and a second housing disposed opposite to each other, and the first fixed arm is disposed in the first housing. 13. The portable electronic device of claim 11, wherein the second housing further has a rectangular hole, and at least a part of the torsion spring body passes through the rectangular hole and is disposed in the display unit. 14. The portable electronic device of claim 11, wherein the first housing further has a sliding track, and the roller is slid along the sliding track. 15. The portable electronic device of claim 14, wherein a distance between a middle part of the sliding track and the side of the host unit is shorter than a distance between each end of the sliding track and the side of the host unit. 16. The portable electronic device of claim 15, wherein the first restoring force is larger when the first extension part is located at the middle part of the sliding track, and the first restoring force is smaller when the first extension part is located at the end part of the sliding track. 17. The portable electronic device of claim 1, wherein the display unit further has a third housing and a fourth housing disposed opposite to each other. 18. The portable electronic device of claim 17, wherein the fourth housing further has an opening, and the display unit further has a display panel exposed from the opening. 19. The portable electronic device of claim 1, wherein the torsion spring body further has a hook part, and the first extension part is connected to the roller by the hook part. 20. The portable electronic device of claim 1, wherein the sliding groove further has a departing part located at one end of the sliding groove.
