4. The massage device of claim 1 , wherein the first massage part has a first free end away from the driving mechanism, and the second massage part has a second free end away from the driving mechanism, and wherein the first free end is further away from the driving mechanism than the second free end.

5. The massage device of claim 1 , wherein the first massage part is configured to perform reciprocating linear motion in a first axis, the second massage part is configured to perform reciprocating linear motion in a second axis, and the first axis is parallel to the second axis.

6. The massage device of claim 1 , wherein at least one of the first massage part and the second massage part is provided with a vibration member.

7. The massage device of claim 6 , wherein the vibration member is a vibration motor.

8. The massage device of claim 6 , wherein the first massage part is configured to perform reciprocating linear motion in a first axis, the first massage part is provided with a first vibration member at a free end thereof, and a central axis of the first vibration member is deflected at an angle relative to the first axis.

9. The massage device of claim 8 , wherein the second massage part is configured to perform reciprocating linear motion in a second axis, the second massage part is provided with a second vibration member at a free end thereof, and a central axis of the second vibration member is deflected at an angle relative to the second axis.

10. The massage device of claim 1 , wherein at least one of the first massage part and the second massage part is provided with a vibration damping member for connection with the driving mechanism.

11. The massage device of claim 10 , wherein the vibration damping member is made of a flexible material.

12. The massage device of claim 1 , wherein the driving mechanism further comprises a first sliding guide member connected to the first slider and a second sliding guide member connected to the second slider, two opposite outer surfaces of the threaded member respectively define a first helical groove and a second helical groove which are symmetrical to each other, the first sliding guide member and the second sliding guide member are slidably engaged in the first helical groove and the second helical groove respectively, and wherein when the first sliding guide member moves linearly towards the driving source, the second sliding guide member moves linearly away from the driving source; and when the first sliding guide member moves linearly away from the driving source, the second sliding guide member moves linearly towards the driving source.

13. The massage device of claim 12 , wherein one end of the first helical groove is communicated to one end of the second helical groove, an other end of the first helical groove is communicated to an other end of the second helical groove, and wherein when the first sliding guide member is engaged in the first helical groove, the second sliding guide member is engaged in the second helical groove; and when the first sliding guide member is engaged in the second helical groove, the second sliding guide member is engaged in the first helical groove.

14. The massage device of claim 1 , wherein the driving mechanism further comprises a first positioning member, a second positioning member and a plurality of guide rails positioned between the first and second positioning members, and the first slider and the second slider are each slidably engaged with one or more guide rails.

15. The massage device of claim 1 , wherein the driving mechanism further comprises a first connecting shaft for connecting the first slider and the first massage part and a second connecting shaft the second slider and the second massage part.

16. The massage device of claim 15 , wherein the first massage part is provided with a first vibration member and a first vibration damping member for connection with the first connecting shaft, and the second massage part is provided with a second vibration member and a second vibration damping member for connection with the second connecting shaft.
