1. A display apparatus, comprising: a display unit; anda support device, connected to the display unit to support the display unit on a flat surface with a supporting angle, the support device comprising: a support bracket, having a pivot hole;a pivot unit, pivotally connected to the pivot hole of the support bracket and connected to the display unit; anda constant force spring, having a spring body mounted on the pivot unit and fixed to the support bracket, wherein when the supporting angle changes in a predetermined range, an end portion of the spring body is movably connected to the support bracket. 2. The display apparatus according to claim 1, wherein the support bracket has a groove, and the end portion moves along the groove while the support bracket rotates with respect to the display unit. 3. The display apparatus according to claim 1, wherein the support device further comprises a torsion spring, the support bracket further has a slot hole, the torsion spring is axially mounted on the pivot unit and adjacent to the constant force spring, one end of the torsion spring is clamped in the slot hole, the torsion spring and the constant force spring cooperatively make the support device support the display unit on the flat surface with the supporting angle and make the support bracket reciprocally rotate with respect to the display unit. 4. The display apparatus according to claim 1, wherein the support device further comprises a limiting unit disposed on the pivot unit and adjacent to the support bracket, the limiting unit limits the supporting angle to a maximum rotation angle. 5. The display apparatus according to claim 4, wherein when the supporting angle is less than the maximum rotation angle, the constant force spring forces the support bracket to return back automatically; when the supporting angle reaches to the maximum rotation angle, the support bracket is limited by the limiting unit to fix at a position and does not automatically return back. 6. The display apparatus according to claim 4, wherein the limiting unit comprises a first washer and a second washer, the first washer has a first stopper portion and the second washer has a second stopper portion, wherein when the support bracket rotates with respect to the display unit, the first washer rotates with respect to the second washer and thereby moving the first and second stopper portions either toward or away from each other. 7. The display apparatus according to claim 6, wherein when the support bracket rotates with respect to the display unit to the maximum rotation angle, the first and second stopper portions interfere with each other to limit the support bracket to further rotate with respect to the display unit. 8. The display apparatus according to claim 5, wherein the support device further comprises a case for containing the support bracket, the pivot unit and the constant force spring therein. 9. The display apparatus according to claim 8, wherein the display unit lies on the flat surface when the support bracket rotates with respect to the display unit to the maximum rotation angle. 10. The display apparatus according to claim 9, wherein the case has a handle structure, through which the case is held. 11. The display apparatus according to claim 8, wherein one end of the case has an cambered surface, through which the case and the flat surface have a line contact while the support device supports the display unit on the flat surface. 12. The display apparatus according to claim 1, wherein the support device further comprises an extension spring module connected to the end portion of the constant force spring and the support bracket. 13. A display apparatus, comprising: a display unit; anda support device, connected to the display unit to support the display unit on a flat surface with a supporting angle, the support device comprising: a support bracket, having a pivot hole, a sidewall and a groove formed on the sidewall;a pivot unit, pivotally connected to the pivot hole of the support bracket and connected to the display unit; anda constant force spring, having a spring body coupled with the pivot unit, wherein when the supporting angle changes in a predetermined range, an end portion of the spring body is movably connected to the support bracket and moves along the groove while the support bracket rotates with respect to the display unit.
