The pin shaft connected to the bottom of the tray 301 is inserted into the pin hole on the carrying base 302 to realize the connection between the tray 301 and the carrying base 302.

[0034] The bottom of the detection rod 6 is mounted on a fixed frame inside the bottom box 1 by bolts, and the installation position of the sensor 601 is on the same horizontal plane as the workpiece blank 7 placed on the top of the material carrying device 3 for detecting the material.

[0035] The reduction box 103 is mounted on the bottom of the top plate 101 by bolts, and the driving motor 102 is mounted on the reduction box 103 by bolts.
