When the connecting rod 8622 is transversely moved on the support plate 8621, the four blocking rods 8623 are inserted into the guide seat 862, so that the four blocking rods 8623 are inserted into the corresponding type of channels, so as to block the components of the next round of discharging, so as to separate the components of the next round of discharging (i.e. the marbles 23, the flat marbles 24, the springs 25 and the aluminum balls 26) from the components of the previous round of discharging. When the installation of the components of the previous round of discharging is completed, the connecting rod 8622 is controlled to move in the opposite direction on the support plate 8621, so that the four blocking rods 8623 are separated from the corresponding type of channels, and then the components automatically fall into the subsequent designated channels. By separating the components, continuous feeding processing is realized. The support plate 8621 is also provided with a second cylinder 8624 whose extension direction is consistent with the movement direction of the connecting rod 8622, and the connecting rod 8622 is installed on the end of the extension rod of the second cylinder 8624.
