Full-automatic bulb replacement manipulator

The invention relates to an electric manipulator, in particular to a full-automatic bulb replacement manipulator. The full-automatic bulb replacement manipulator comprises an extension rod and multiple clamping rods which are mounted at the upper end of the extension rod and can relatively extend and contract. The extension rod comprises an upper rod body and a lower rod body which are coaxially inserted together and are relatively rotatable. The clamping rods are mounted at the upper end of the upper rod body through hanging lugs. The middle segments of the clamping rods are connected with pull wires. A sliding block connected to the pull wires is arranged in an inner cavity of the upper rod body. The upper end of the lower rod body is connected with the upper rod body through a gear box. The upper rod body is connected with a drive motor in a transmission manner. A handle for driving the sliding block to move in the axial direction is mounted on the lower rod body. The manipulator is compact in structure, c
