An adjusting mechanism adapted to adjust a position of a projection unit relative to a fixing object is provided. The adjusting mechanism includes a base, a sliding plate, a first screw, and an elastic element. The base is adapted to be fixed to the fixing object. The sliding plate is slidably disposed on the base along a first axis and adapted to be fixed to the projection unit. The first screw is fixed to the sliding plate and screwed to the base, wherein the first screw drives the projection unit to move relatively to the base along the first axis when the first screw is rotated. The elastic element is compressed between the base and the sliding plate along the first axis.

1. An adjusting mechanism, adapted to adjust a position of a projection unit relative to a fixing object, the adjusting mechanism comprising: a base adapted to be fixed to the fixing object;a sliding plate slidably disposed on the base along a first axis and adapted to be fixed to the projection unit;a first screw fixed to the sliding plate and screwed to the base, wherein the first screw drives the projection unit to move relatively to the base along the first axis when the first screw is rotated; andan elastic element compressed between the base and the sliding plate along the first axis. 2. The adjusting mechanism as claimed in claim 1, wherein the base comprising: a fixing plate adapted to be fixed to the fixing object; anda shell fixed to the fixing plate and covering the elastic element, wherein the elastic element is compressed between the shell and the sliding plate. 3. The adjusting mechanism as claimed in claim 2, wherein the base further comprising: a screw portion fixed to the fixing plate and having a screw hole, wherein the first screw is screwed through the screw hole. 4. The adjusting mechanism as claimed in claim 1, wherein the elastic element is a spring. 5. The adjusting mechanism as claimed in claim 1, further comprising: a rotary plate pivotally connected to the sliding plate and adapted to be ball jointed to the projection unit; anda second screw screwed to the rotary plate and adapted to be ball-jointed to the projection unit, wherein the second screw drives the projection unit to rotate relatively to the rotary plate along a second axis when the second screw is rotated. 6. The adjusting mechanism as claimed in claim 5, further comprising: a third screw screwed to the rotary plate and adapted to be ball-jointed to the projection unit, wherein the third screw drives the projection unit to rotate relatively to the rotary plate along a third axis when the third screw is rotated, and the third axis is substantially perpendicular to the second axis. 7. The adjusting mechanism as claimed in claim 6, further comprising: a fourth screw screwed to the sliding plate and connected to the rotary plate, wherein the fourth screw drives the rotary plate to rotate relatively to the sliding plate along a fourth axis when the fourth screw is rotated, and the fourth axis is substantially perpendicular to the second axis and the third axis. 8. The adjusting mechanism as claimed in claim 5, further comprising: an interface sheet adapted to be fixed on the projection unit, wherein the second screw is ball-jointed to the interface sheet, and the rotary plate is ball-jointed to the interface sheet. 9. A projector, comprising: a projection unit; andan adjusting mechanism, comprising: a base adapted to be fixed to a fixing object;a sliding plate slidably disposed on the base along an first axis and fixed to the projection unit;a first screw fixed to the sliding plate and screwed to the base, wherein the first screw drives the projection unit to move relatively to the base along the first axis when the first screw is rotated; andan elastic element compressed between the base and the sliding plate along the first axis. 10. The projector as claimed in claim 9, wherein the base comprising: a fixing plate adapted to be fixed to the fixing object; anda shell fixed to the fixing plate and covering the elastic element, wherein the elastic element is compressed between the shell and the sliding plate. 11. The projector as claimed in claim 10, wherein the base further comprising: a screw portion fixed to the fixing plate and having a screw hole, wherein the first screw is screwed through the screw hole. 12. The projector as claimed in claim 9, wherein the elastic element is a spring. 13. The projector as claimed in claim 9, wherein the adjusting mechanism further comprising: a rotary plate pivotally connected to the sliding plate and ball jointed to the projection unit; anda second screw screwed to the rotary plate and ball-jointed to the projection unit, wherein the second screw drives the projection unit to rotate relatively to the rotary plate along a second axis when the second screw is rotated. 14. The projector as claimed in claim 13, wherein the adjusting mechanism further comprising: a third screw screwed to the rotary plate and ball-jointed to the projection unit, wherein the third screw drives the projection unit to rotate relatively to the rotary plate along a third axis when the third screw is rotated, and the third axis is substantially perpendicular to the second axis. 15. The projector as claimed in claim 14, wherein the adjusting mechanism further comprising: a fourth screw screwed to the sliding plate and connected to the rotary plate, wherein the fourth screw drives the rotary plate to rotate relatively to the sliding plate along a fourth axis when the fourth screw is rotated, and the fourth axis is substantially perpendicular to the second axis and the third axis. 16. The projector as claimed in claim 13, wherein the adjusting mechanism further comprising: an interface sheet fixed on the projection unit, wherein the second screw is ball jointed to the interface sheet, and the rotary plate is ball-jointed to the interface sheet.
