[0012] The adoption of such a structure can protect the quadrilateral mold of the concrete test block and prevent the quadrilateral mold of the concrete test block from being damaged by rigid collision.

[0013] As a further improvement of the utility model, flanges are provided on the upper and lower sides of the quadrilateral mold of the concrete test block, and the flanges fit the inner side surface of the first angle steel.

[0014] With such a structure, the flange is more convenient to hold.

[0016] With such a structure, it can be leveled on the inclined ground, which is convenient for subsequent demoulding.

[0017] As a further improvement of the utility model, a pad is arranged under the second buffer pad, and the pad is placed on the second angle steel.

[0018] With this structure, after leveling on the slope, the concrete test block will fall directly onto the pad.

[0019] The utility model can be used for a plurality of concrete test molds one by one, is easy to turn around, consumes less materials and is conducive to demoulding. BRIEF DESCRIPTION OF THE DRAWINGS
