[0074] In the folded state, the spoon body, the second folding portion, and the first folding portion form a triple folding structure that overlaps in sequence, that is, the spoon body and the first folding portion are both rotated in the direction where the second folding portion is located;

[0075] In the unfolded state, the spoon body, the second folding portion, and the first folding portion are sequentially connected to form a spoon-shaped structure, that is, the first folding portion and the second folding portion form a straight-line spoon handle.

[0076] Preferably, both ends of the second folding portion 162b are connected to the spoon body 161 and the first folding portion 162a by a rotating connection rather than a hinged connection as used in existing folding spoons. With this arrangement, the spoon is less likely to deform and more stable when in use, thereby improving the feel of using the spoon.

[0077] In this embodiment, rotating holes are provided at corresponding positions of the connection between the spoon body, the second folding part and the first folding part, and the rotating connection is achieved by the rotating shaft passing through the rotating holes opposite to each other.
