[0023] In this embodiment, the rotating mechanism is started to drive the mounting plate 3 to intermittently rotate with the connection point of the rotating mechanism as the center, so that the multiple clamping mechanisms on the mounting plate 3 rotate one by one and transmit to the transmission mechanism, so that the bearing shafts can be placed one by one in the multiple clamping mechanisms for clamping.
