Then, one end of the shaft can be sequentially passed through the placing plates 301 on the two placing racks 3, and one end of the shaft enters the limiting cylinder 202 and abuts against the limiting cylinder 202. Secondly, install the second limiting plate 201, and make the limiting cylinder 202 on the rear end surface of the second limiting plate 201 abut against the other end of the transport shaft. Thus, it realizes that the positions of the placing rack 3 and the second limiting plate 201 can be flexibly changed according to the length of the transport shaft, thereby realizing the separate limiting of the two ends of multiple transport shafts, improving the flexibility of the transfer rack 1, and avoiding the problem that the transport shaft disengages from the transfer rack 1.

[0023] As a technical optimization scheme of the present invention, positioning rods 307 are fixedly connected to the left and right sides of the lower end surface of the pressing plate 302, and positioning grooves matching the positioning rods 307 are opened on the left and right sides of the upper end surface of the placing plate 301.
