A lift mechanism for a motor according to claim 2, wherein: the lifting mechanism comprises a first group, a second group, a third group and a fourth group of rhombic lifting components, wherein the first group and the third group of rhombic lifting components and the second group and the fourth group of rhombic lifting components are respectively distributed along two sides of the axis of the transmission shaft; the first group of rhombic lifting components and the second group of rhombic lifting components are respectively connected with the two cam seats on the transmission shaft through the first connecting piece, and the deflection moving directions of the two cam seats are opposite when the two cam seats rotate along with the transmission shaft; the third group and the fourth group of rhombic lifting assemblies are respectively connected with the two cam seats on the transmission shaft through the first connecting piece, and the deflection moving directions of the two cam seats are opposite when the two cam seats rotate along with the transmission shaft.
4. A lifting mechanism for a motor according to claim 2 or 3, wherein: the auxiliary structure comprises a second connecting piece and an auxiliary cam; the auxiliary cam is arranged on the transmission shaft in a rotation stopping manner; one end of the second connecting piece is hinged to the other free end of the rhombic lifting component, and the other end of the second connecting piece is sleeved on the auxiliary cam; the cam seat and the auxiliary cam which are correspondingly sleeved and connected with the first connecting piece and the second connecting piece which are hinged on the same group of rhombic lifting structures have opposite deflection displacement directions.
5. A lift mechanism for a motor according to claim 2, wherein: the driving piece is a motor.
6. The lift mechanism for a motor of claim 5, wherein: the motor drives the transmission shaft to rotate through a transmission belt.
7. The lift mechanism for a motor of claim 5, wherein: the connecting rod of the rhombic lifting component is made of a nylon material.
8. A rhythm machine comprises a shell, a fixed seat and a bearing platform; the method is characterized in that: further comprising a lifting mechanism as claimed in any one of claims 1 to 7; the shell and the lifting mechanism are integrally formed or are arranged in the shell; the fixed end of the lifting structure is hinged with the base; the bearing platform is connected with the lifting surface or integrally formed.
