In order to improve its shortcomings, the present invention provides a bamboo board hardness test and support positioning simulation device.

[0005] To achieve the above object, the present invention is achieved through the following technical solutions:

[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0007] As a preferred solution, abutment screws are screwed onto the frames on both sides of the support head, a rotating head is integrally provided on the outer free end of the abutment screw, and the inner free end of the abutment screw abuts against the side end surface of the bamboo wood board to be tested.

[0008] As a preferred solution, a sliding block is fixed on the back of the movable plate, a vertical sliding rail is arranged in a fixed seat directly opposite to the sliding block, and the movable plate is slidably connected to the corresponding sliding rail via the sliding block.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1) Through the cooperation of the pin shaft and the inclined groove, the spacing between the sliding seats is always kept the same during the up and down movement of the movable plate, which is convenient for the tester to obtain the best setting spacing according to the stress conditions of the bamboo board under different spacings between adjacent support heads;

[0013] 2) The setting of the abutment screws on both sides of the frame fixes the bamboo board to be tested on the side, avoiding inaccurate test parameters caused by the fluctuation of the bamboo board during the pressing process of the extrusion head.
