With the rapid development of the world's social economy today, the demand for special steels in all walks of life is becoming more and more extensive. Most of the electric furnaces in use so far use graphite electrodes of different specifications. As a conductive material in electric furnace smelting, the consumption of graphite electrodes is proportional to the smelting time in the electric furnace.

During the alignment, the upper electrode is adjusted by the lifting mechanism, and the electrode is repeatedly moved in a small range to align with the other electrode. The operation of the work is difficult. During the alignment process, the two electrodes may collide, causing the lower electrode to tip over due to loose fixation, thereby causing certain safety hazards, and the efficiency is low during the connection.

The rotating roller 3, the driving paddle 31, the driving motor 32 and the connecting paddle 4 form a driving structure, and the rotating roller 3 is driven to rotate by the driving motor 32. During the rotation of the rotating roller 3, the driving paddle 31 is connected to the connecting paddle 4 by transmission, thereby driving the new material limiting mechanism 13 to rotate, and the new material limiting mechanism 13 is driven to rotate. After the graphite electrode in the structure 13 is aligned with the graphite electrode below, the new material limiting mechanism 13 is driven to rotate by the driving mechanism to connect the two graphite electrodes, so that the two graphite electrodes can be positioned at the same time when the two graphite electrodes are connected, so that the connection between the two graphite electrodes can be quickly aligned, and there is no need to drive the upper graphite electrode to move back and forth through the lifting structure to align with the other graphite electrode, thereby reducing the difficulty of operation in the process of connecting the graphite electrodes, and quickly aligning during the connection, thereby improving the connection efficiency of the graphite electrodes.

[0020] Two connecting grooves 221 are symmetrically provided on the top of the base 1, and the connecting block 22 is slidably connected inside the connecting groove 221, and the connecting groove 221 is connected to the connecting cavity 231; by providing the connecting groove 221 and the connecting cavity 231, the driver 23 is installed so that the connecting block 22 can slide smoothly inside the connecting groove 221.
