[0009] The motor drive assembly includes motor, speed reducer and chain wheel.

[0010] Further, the movable cross bar has through holes on two sides, two steel wires pass through the through holes on the movable cross bar in sequence and are fixed by a steel wire clamp.

[0011] Further, the cage has cage curtain doors on the slide rails on two sides and limiting angle irons in the predetermined positions.

[0012] The working principle of the utility model is as follows:

[0013] The motor is controlled to rotate reversely by the electrical control system, the micro winding drum is driven to rotate reversely by the transmission shaft, two steel wires wound on the micro winding drum are connected with the lowest horizontal bars of the fence type cage curtain door through two groups of guide rope wheels on two sides, the micro winding drum rotates, the steel wires are wound or loosened to drive the fence type cage curtain door to open or close in the slide rail. When the cage curtain door is in the closed state, the motor rotates to drive the winding drum to wind the steel wire, so that the cage curtain door horizontal bar is slowly moved upward, and the cage curtain door is opened. When the cage curtain door is in the opened state, the motor drives the winding drum to loosen the steel wire, and the cage curtain door slowly moves downward under the action of the self weight until the cage curtain door is closed.
