[0074] Example 3

[0075] As Figures 11-13As shown, the electrode 10 is accumulated in the storage cavity, and the electrode 10 cannot enter the lowermost position due to the restriction of the pusher 604. When the pusher 604 rotates around the fixed shaft A 603 under the action of the push rod 601, the gap between the pusher 604 and the bottom of the storage cavity is enlarged, and one electrode 10 is just accommodated in the gap. However, if two electrodes 10 simultaneously move to the gap at this time, no electrode 10 enters the gap. At this time, the pusher 604 returns to the initial position under the action of the feeding spring 605, but due to the obstruction of the two electrodes 10, the two electrodes 10 are stuck with the pusher 604, and normal feeding is impossible. At this time, the feeding button 2 is pressed for a long time, the movable pusher motor 12 and the feeding motor 6 are started, and the feeding motor repeats the feeding process. When the gap between the pusher 604 and the bottom of the storage cavity is enlarged again, the movable pusher motor 12 drives the movable pusher 11 to move up and down, breaks the force balance of the stuck electrode 10, makes one electrode enter the gap, and makes the pusher 604 restore to normal discharge.
