In accordance with another aspect of the present invention, the present invention further provides a method of operating a harvester 1000, wherein the method of operating comprises the steps of:

(a) the coupling projection 21 receiving the coupling body 20;

(b) moving the movable member 121 of the movable element 12 of the assembly body 10 in a manner of moving toward the connecting protrusion 21 of the connecting body 20, and driving the limiting member 122 to move toward the connecting body 20; and

(c) the coupling projection 21 and the coupling arm 22 of the coupling body 20 enter the fitting space 102 and the stopper groove 103 of the movable member 12, respectively, to complete the assembly of the harvester 1000.

Specifically, in the step (a), the coupling projection 21 of the coupling body 20 enters the movable space 110 of the fitting housing 11 from the fitting opening 101.

In the step (b), the movable piece 121 pulling the movable element 12 in such a manner as to rotate the driving element 31 moves within the movable space 110 of the fitting housing 11.

In the above method, the position-limiting pillar 33 moves from the first position-limiting hole 3221 to the second position-limiting hole 3222. Specifically, in the above method, further comprising the step of: the driving element 31 is moved downward, and the position-limiting post 33 is separated from the first position-limiting hole 3221. At the same time, the elastic member 36 is compressed downward. When the driving element 31 rotates from a position corresponding to the first position-limiting hole 3221 to a position corresponding to the second position-limiting hole 3222, the elastic element 36 pushes the driving element 31 to move upward, and the position-limiting pillar 33 enters the second position-limiting hole 3222.

Further, after the step (c), the connecting body 20 and the fitting body 10 are disassembled. Specifically, the movable member 121 of the movable element 12 of the assembly body 10 is moved in a manner of moving away from the connecting protrusion 21 of the connecting body 20, and the limiting member 122 is driven to move away from the connecting body 20.

In the above method, the movable member 121 of the movable element 12 is pushed in such a manner as to rotate the driving element 31.

In the above method, the position-limiting pillar 33 moves from the second position-limiting hole 3222 to the first position-limiting hole 3221. Specifically, in the above method, further comprising the step of: the driving element 31 is moved downward and the position-limiting post 33 is moved away from the second position-limiting hole 3222. At the same time, the elastic member 36 is compressed downward. When the driving element 31 rotates from the position corresponding to the second position-limiting hole 3222 to the position corresponding to the first position-limiting hole 3221, the elastic element 36 pushes the driving element 31 to move upward, and the position-limiting pillar 33 enters the first position-limiting hole 3221. At this time, the coupling projection 21 and the coupling arm 22 of the coupling body 20 are allowed to be separated from the fitting body 20.
