Through the work of motor two 9, rotating cylinder 8 can be controlled to rotate, control shaft 10 is deflected, and signal transmitter one 12 transmits position signals.

When the signal can be received, the signal cannot be accepted, and the detection of the size of the hole can be realized. After the detection is completed, the bearing is pushed out and located on the supporting roller 7 to realize the transfer.
