[0007] Preferably, a pair of fixing holes are formed in the base.

[0008] Preferably, the avoiding grooves are annularly distributed in horizontal direction on the sleeve.

[0009] Preferably, the avoiding grooves are layered arranged in vertical direction on the sleeve.

[0010] The beneficial effects achieved by the above technical solutions are:

[0011] 1. By setting the hydraulic cylinder, slide cylinder, sleeve, brace rod and other components, the supporting plate is set as a retractable form, when the seedlings on the seedling support are used up, the supporting plate can be retracted by the hydraulic cylinder, which not only can increase the working space on the rice transplanter, improve the safety of the staff, but also can improve the stability of the rice transplanter when walking.

[0012] 2. By installing the handle on the sleeve, the sleeve can be rotated during use, the position of the supporting plate is adjusted, the staff can take the seedlings conveniently, and the convenience of the staff to take the seedlings is effectively improved. BRIEF DESCRIPTION OF DRAWINGS
