3. The transmission mechanism according to claim 2, wherein the transmission assembly includes a first transmission structure, a second transmission structure and a third transmission structure which are rotatably connected in sequence, the first transmission structure is further rotatably connected to the driving assembly, the third transmission structure is further rotatably connected to the abutting member, and the driving assembly is configured to drive the first transmission structure to eccentrically rotate in a preset space, so as to drive the second transmission structure to reciprocally swing in a preset plane, and further drive the third transmission structure to reciprocally move along an axial direction of the abutting member, so as to drive the abutting member to reciprocally move along the axial direction of the abutting member relative to the elastic shaft sleeve.
4. The transmission mechanism as claimed in claim 3, wherein the driving assembly includes a power source and a fourth transmission structure connected to each other, the fourth transmission structure is further rotatably connected to the first transmission structure, and the power source is configured to drive the fourth transmission structure to rotate around an axial direction of the power source, so as to drive the first transmission structure to rotate eccentrically in the predetermined space.
5. The transmission mechanism as claimed in claim 4, wherein the fourth transmission structure comprises a connecting member and a transmission member connected with each other, wherein one end of the connecting member away from the transmission member is connected with the power source, and one end of the transmission member away from the connecting member is rotatably connected with the first transmission structure; the axial direction of the transmission part and the axial direction of the connecting part are arranged at a preset acute angle; the power source is used for driving the connecting piece to rotate around the self axial direction so as to drive the transmission piece to rotate around the axial eccentricity of the connecting piece, and further drive the first transmission structure to rotate around the axial eccentricity of the connecting piece in a preset space.
6. The transmission mechanism as claimed in claim 5, wherein the fourth transmission structure includes an intermediate member, the intermediate member being disposed between the connecting member and the transmission member; the intermediate member is including the first side and the second side of back to setting up, first side with the acute angle setting is predetermine to the second side, first side with the connecting piece is connected perpendicularly, the second side with the driving medium is connected perpendicularly, so that the axial of driving medium with the axial of connecting piece is predetermine the acute angle setting.
7. The transmission mechanism as recited in claim 4, wherein the transmission assembly further comprises a first bearing disposed within the first transmission structure, and wherein the fourth transmission structure is rotationally coupled to the first transmission structure via the first bearing.
8. The transmission mechanism according to claim 3, wherein the second transmission structure is provided with a space avoiding portion, and the space avoiding portion is used for avoiding the third transmission structure in the process of reciprocating movement along the axial direction of the pushing member.
9. The transmission mechanism as claimed in claim 1, wherein a protection member for fixing and protecting the elastic bushing is sleeved outside the elastic bushing.
10. A fascial gun, comprising:
a transmission according to any one of claims 1 to 9; and
and the massage raised head is connected with the pushing piece.
