Cradle movement mechanism and crib

A cradle movement mechanism, comprising a vertical movement mechanism, a horizontal rotation mechanism and a mounting base, wherein

• the vertical movement mechanism comprises a first driving member, a lead screw and a nut, the first driving member drives the lead screw to rotate forward and backward, so that the nut moves up and down along the lead screw to drive the mounting base fixed on the nut to move up and down;
• the horizontal rotation mechanism comprises a second driving member and a main rotor;
• the main rotor is fixedly connected with the vertical movement mechanism, and when the second driving member drives the main rotor to rotate, the vertical movement mechanism and the mounting base are driven to do a horizontal circular movement;
• wherein the first driving member comprises a first motor, a first driving belt pulley, a first driven belt pulley and a first reducer box;
• the first driving belt pulley and the first driven belt pulley are in transmission connection by a belt;
• the first driving belt pulley is connected with the first motor by the first reducer box;
• the first driven belt pulley is fixedly connected with the lead screw;
• the first motor drives the first reducer box to rotate the first driving belt pulley, so that the first driven belt pulley drives the lead screw to rotate.
