Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation manners, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0018] It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present utility model in a schematic manner. Therefore, only the components related to the present utility model are shown in the drawings, rather than being drawn according to the number, shape and size of the components in actual implementation. The type, quantity and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0019] All directional indications (such as up, down, left, right, front, back, horizontal, vertical...) in the embodiments of the present utility model are only used to explain the relative position relationship and movement conditions between components in a certain specific posture. If this specific posture changes, then the directional indications will also change accordingly.

[0020] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of the present utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0021] This embodiment discloses a fastening device for fixing specimens of water absorption thickness swelling rate. Among them, the specimen 3 of water absorption thickness swelling rate includes, but is not limited to, wood-based panels and veneered wood-based panels in various types of board products. Its water absorption thickness swelling rate is one of the important performance indicators of the board, so it needs to be measured. In this embodiment, the specimen 3 of water absorption thickness swelling rate has a rectangular flat structure, preferably a square flat structure.

[0022] Referring to Figure 1 , the fastening device includes a bracket and a plate body. The bracket includes a base 1 and a column 11. The base 1 is used to be placed flat on any plane. The column 11 is arranged on the upper surface of the base 1 and is fixedly connected to the base 1. And the column 11 extends vertically upward. In this embodiment, the column 11 includes four, and they are respectively arranged at the four corners of the base 1 for supporting the plate body.

[0023] The number of the plate bodies is set to two or more. The plate bodies have a flat structure and are arranged horizontally. A plurality of the plate bodies are stacked in parallel along the direction of the column 11. And the vertical distance between adjacent plate bodies is the same and is a settable distance, which is set according to the actual size of the specimen 3.

[0024] Four clamping claws 24 are arranged on the side of the plate body. There is an opening between the clamping claws 24. The four columns 11 respectively pass through the openings of the four clamping claws 24. Through the deformation of the clamping claws 24, the clamping claws 24 are in interference fit with the columns 11, so as to fix the plate body on the columns 11.
