1. A massager with four heads arranged on the ends of four elongated holders, wherein said holders with heads are arranged so that forming four working planes of the massager each of them is the tangent to the surfaces of three heads and intersects with other working surfaces forming an imaginary tetrahedral pyramid, inside each of trihedral angle of which close to its vertex one of said working heads is arranged, and inside the pyramid at some distance from each of said working planes a point of said holders' connection, characterized in that at least one of said working heads is coaxial to at least one convexity of the holder and/or to the convexity the axis of which is perpendicular to one of the massager working planes. 2. The massager according to claim 1, characterized in that all four working heads are similar in shape and size and with convexities having axes perpendicular to two of four working planes, said convexities are similar in shape and and/or size and with convexities having the axes perpendicular to the third working plane, said convexities are similar or different in shape and sizes, and three of the heads are different from each other in shape and /or sizes convexities coaxial to their holders. 3. The massager according to claim 1 or 2, characterized in that said convexity is in the form of spherical, or cylindrical or conical protrusion with a rounded end. 4. The massager according to claim 1 or 2, characterized in that said convexity is in the form of several spherical, or cylindrical or conical protrusions with a rounded ends. 5. The massager according to claim 1 or 2, characterized in that said convexity is made the form an insert embedded into the head of a material other than the head material. 6. The massager according to claim 5, characterized in that said insert is in the form of spherical, cylindrical or conical protrusion with a rounded end. 7. The massager according to claim 5 or 6, characterized in that said insert is made of metal or alloy. 8. The massager according to claim 7, characterized in that a continuous single or multi-layer coating is applied to said insert of a material other than the insert material. 9. The massager according to claim 7, characterized in that a continuous single or multi-layer coating is applied to said insert of a material other than the insert material exposing each of said coating layer on the convexity top. 10. The massager according to claim 7, characterized in that a material other than the insert material is applied on the insert top. 11. The massager according to claim 5 or 6, characterized in that the insert is wooden. 12. The massager according to claim 5 or 6, characterized in that the insert is made of a natural body in the form of a spherical, cylindrical or conical protrusion with a rounded end, or in a natural shape. 13. The massager according to claim 5 or 6, characterized in that the insert is a permanent magnet.
