The invention discloses a focusing structure of a micro-projection display apparatus and the micro-projection display apparatus. The focusing structure of the micro-projection display apparatus comprises a base plate, a motor, a ray machine, a controller, a first transmission component and a second transmission component, wherein the motor, the ray machine and the controller are arranged on the base plate; and the first transmission component and the second transmission component are used for connecting the motor and the ray machine. The controller is electrically connected to the motor. A first end of the first transmission component is fixedly connected to a rotation shaft of the motor. A second end of the first transmission component is hinged to a first end of the second transmission component. A second end of the second transmission component is hinged to a focusing wheel of the ray machine. In the technical scheme, convenience of micro-projection display apparatus focusing can be increased.
