Sample clamping assembly for composite laminate compression test and using method

The invention discloses a sample clamping assembly for a composite laminate compression test and a using method. The sample clamping assembly comprises an upper compression block, a lower compressionblock and two wedge-shaped clamping blocks. The upper compression block is provided with an annular clamping ring and a wedge-shaped groove, and the wedge-shaped groove is located in the middle of theannular clamping ring. An annular guide groove and a wedge-shaped groove are formed in the lower compression block, and the wedge-shaped groove is located in the middle of the annular guide groove; the annular clamping ring is matched with the annular guide groove; one wedge-shaped clamping block is matched with the wedge-shaped groove of the upper compression block, and the other wedge-shaped clamping block is matched with the wedge-shaped groove of the lower compression block; and the wedge-shaped clamping block is formed by clamping a clamping block I and a clamping block II so as to realize quick fixing or taking
