[0006] Preferably, the support plate is a recessed plate, and the support plate is arranged to fit the arm bracket.

[0007] Preferably, ear plates are fixed on both sides of the support plate.

[0008] Preferably, the sowing assembly includes a sowing sleeve fixed below the hopper, the sowing sleeve is provided with a horizontal outlet, a rotating plate is installed inside the sowing sleeve, a paddle is fixed to the edge of the rotating plate; the edge of the rotating plate points to the outlet; the rotating plate is located below the connecting hole.

[0009] Preferably, the sowing sleeve is rotatably connected to a lower shaft, and the rotating plate is fixed to the lower shaft; the lower shaft and the upper shaft are linked; and the lower shaft is connected to a driving assembly.

[0010] Preferably, the driving assembly is a rotating handle, and the rotating handle is drivingly connected to the lower shaft.

[0011] Preferably, the driving assembly includes a motor and a power source, and the output shaft of the motor is connected to the lower shaft.

[0012] Preferably, the communicating hole is provided with a sliding sealing plate, and the lifting handle is provided with a button for driving the sealing plate to open the communicating hole.

[0013] In summary, the utility model has the following beneficial effects:

[0014] (1) The rotating arm bracket allows the user to press down with his / her back arm, thereby reducing the force exerted by the planter on the user's wrist and reducing wrist wear.

[0015] (2) The support plate is designed as a recessed plate. First, the lifting support plate fits closely to the lifting handle, making it more comfortable for the user to lift the planter. Second, the arm fits more tightly in the recessed support plate, making it more comfortable. In addition, the protrusions on both sides of the support plate can prevent the arm from slipping off the support plate.

[0016] (3) The length of the support plate is greater than that of the seesaw, which acts as a lever. Secondly, the seesaw can resist the lifting handle, so that the support plate can be quickly adjusted to the folded and unfolded states by rotating;

[0017] The function of the ear plate is to make it easier for users to move the support plate. BRIEF DESCRIPTION OF THE DRAWINGS
