Eight profiled grooves matched with the product are provided on the external machine, eight products are placed in the profiled grooves by hand, the mounting frame 1 is positioned on the external machine, the wireless communication board 5 realizes wireless communication with the product through RFID technology, so as to upload or download information, the uploaded or downloaded information is connected to the MAC Mini through the probe module 2 and the connector on the external machine, and the bidirectional transmission of information between the Mac mini and the product is realized.

[0018] As shown in Figure 5 and Figure 6As shown, in this embodiment, the probe module 2 includes a mounting block 7 and an adapter board 8. The adapter board 8 is disposed within the mounting block 7. A plurality of USB ports 9 are provided on the top of the adapter board 8, passing through the top of the mounting block 7 and connecting to the wireless communication board 5. A probe block 10 is provided on the bottom of the adapter board 8, passing through the bottom of the mounting block 7 and connecting to the connector of an external device. The wireless communication board 5 is connected to the USB ports 9 via a data cable. Information acquired by the wireless communication board 5 passes sequentially through the data cable, the USB ports 9, the adapter board 8, and the probe block 10, and is finally transmitted to the connector of the external device.

[0019] like Figure 5 and Figure 6 As shown, in this embodiment, the mounting block 7 is located at the center of the mounting frame 1. Equalizing screws 11 are provided at both ends of the mounting block 7, and the ends of the equalizing screws 11 have external threads.
