Adjustable auxiliary test device for detecting hardness of clamping piece

The invention discloses an adjustable auxiliary test device for detecting the hardness of a clamping piece, and relates to the technical field of hardness detection. The device comprises a base, a vertical supporting rod and an adjustable supporting block, the adjustable supporting block comprises a supporting block body and a semi-cylinder, one end of the supporting block body is movably connected with the base, and the other end of the supporting block body is connected with the upper end of the vertical supporting rod which is in threaded connection with the base. The inclination angle of the adjustable supporting block is adjusted through the vertical supporting rod, so that the upper surface of the clamping piece sample is kept horizontal, it is guaranteed that the detected surface ofthe clamping piece sample is perpendicular to the stress application direction, and detection of the clamping piece sample at different inclination angles is achieved; the clamping piece sample is clamped and sleeved outside
