The first panel is configured with a clamping means for clamping paper, the first panel is configured to be hinged with the second panel via a first hinged part, the second panel is configured to be hinged with the third panel via a second hinged part, and the third panel is configured to be hinged with the fourth panel via a third hinged part. The first hinged part is disposed on both side edges of the first panel and protrudes from an upper surface of the first panel. With the cooperation of the first panel, the second panel, the third panel and the fourth panel, the multi-foldable clipboard can achieve a small storage volume while ensuring a larger unfolding size, thus improving use experience.
