Then the base 1 is reset and the driving motor 2 makes the rotating drum 3 and the rotating disk 4 rotate forty-five degrees for welding again. When it rotates forty-five degrees again, the above action is repeated to achieve the purpose of continuous automatic feeding. When the rotating disk 4 rotates, it will drive the annular block 1 23 and the annular block 24 below to rotate synchronously, so that the sliding ball 26 under the annular block 1 23 and the sliding ball 26 under the annular block 24 move in the annular groove 1 21 and the annular groove 22 respectively.
