[0030] In this embodiment: the seedlings to be transported are moved onto the bottom plate 1 so that the root part of the seedlings is placed in the hemispherical base 401. At this time, the first motor 404 is powered on and operated so that the output shaft of the first motor 404 in the operating state drives a rotating shaft 409 and a transmission gear 4010 to rotate. Since the transmission gear 4010 is meshed with the connecting gear 4011, the rotating transmission gear 4010 drives the connecting gear 4011 to rotate, and the rotating connecting gear 4011 drives another rotating shaft 409 to rotate. Then, the two rotating shafts 409 in the synchronously rotating state respectively drive the two limiting plates 402 to rotate close to each other. The two limiting plates 402 in the close rotating state wrap the root part of the seedling, and then the two limiting plates 402 in the closed state cooperate with the hemispherical base 401 to provide limiting support for the root part of the seedling.

[0037] In this embodiment: the second motor 408 is powered on and operated, so that the output shaft of the second motor 408 in the running state drives the bidirectional screw rod 406 to rotate, and the bidirectional screw rod 406 in the rotating state drives the two limit frames 407 to move along the outer wall trajectory of the guide rod 4012. Since the end inner cavity of one limit frame 407 is provided with an internal thread meshing with the positive thread of the bidirectional screw rod 406, and the end inner cavity of the other limit frame 407 is provided with an internal thread meshing with the reverse thread of the bidirectional screw rod 406, one limit frame 407 moves along the positive thread trajectory of the bidirectional screw rod 406, and the other limit frame 407 moves along the reverse thread trajectory of the bidirectional screw rod 406, then the two limit frames 407 move close to each other, and the two limit frames 407 in the close moving state wrap the branches and stems of the seedlings, and then the two limit frames 407 in the closed state provide limit support for the branches and stems of the seedlings.

[0038] Please refer to Figure 2 The inner cavity at the end of one limit frame 407 is provided with an internal thread that meshes with the positive thread of the bidirectional screw rod 406 , and the inner cavity at the end of the other limit frame 407 is provided with an internal thread that meshes with the reverse thread of the bidirectional screw rod 406 .

Then, the two rotating shafts 409 in the synchronous rotating state respectively drive the two limiting plates 402 to rotate close to each other. The two limiting plates 402 in the close rotating state wrap the root part of the seedling, and then the two limiting plates 402 in the closed state cooperate with the hemispherical base 401 to limit and support the root part of the seedling.

[0043] At this time, the second motor 408 is powered on and operated, so that the output shaft of the second motor 408 in the running state drives the bidirectional screw rod 406 to rotate, and the bidirectional screw rod 406 in the rotating state drives the two limit frames 407 to move along the outer wall trajectory of the guide rod 4012. Since the end inner cavity of one limit frame 407 is provided with an internal thread meshing with the positive thread of the bidirectional screw rod 406, and the end inner cavity of the other limit frame 407 is provided with an internal thread meshing with the reverse thread of the bidirectional screw rod 406, one limit frame 407 moves along the positive thread trajectory of the bidirectional screw rod 406, and the other limit frame 407 moves along the reverse thread trajectory of the bidirectional screw rod 406, then the two limit frames 407 move close to each other, and the two limit frames 407 in the close moving state wrap the branches and stems of the seedlings, and then the two limit frames 407 in the closed state provide limit support for the branches and stems of the seedlings, so that the seedlings to be transported are limited and supported through the above structure, so as to prevent the seedlings from easily tipping over during transplanting and transportation.
