When the device is used, a high-performance aluminum alloy sample is placed into the circular groove 12, then the high-pressure gas tank 3 is opened, so that high-pressure gas in the high-pressure gas tank 3 flows into the protective shell 21 of the clamping device 2 along the first channel 211, the air pressure in the protective shell 21 is increased, the piston plate 23 is pressed to move and drives the first pressure rod 24 to move, and the arc-shaped clamping plate 25 at the end part of the first pressure rod 24 moves along with the first pressure rod 24 and is in contact with the irregular outer surface of the high-performance aluminum alloy sample; because the surface of the arc-shaped clamping plate 25, which is in contact with the high-performance aluminum alloy sample, is bent towards the direction far away from the circular groove 12, the contact surface of the arc-shaped clamping plate 25 and the high-performance aluminum alloy sample is increased, and the outer surface of the high-performance aluminum alloy sample is uniformly stressed by the pressure pointing to the center of the circular groove 12, so that the high-performance aluminum alloy sample is tightly fixed in the circular groove 12, and the high-performance aluminum alloy sample can be stably treated by various detection equipment on a detection platform;

because the arc-shaped air bag 252 has certain elasticity, the surface of the arc-shaped air bag 252 deforms to a certain extent when contacting with the high-performance aluminum alloy test sample, so that the surface of the arc-shaped air bag 252 is contacted with the high-performance aluminum alloy test sample more tightly, and the relative friction between the arc-shaped air bag 252 and the high-performance aluminum alloy test sample is larger; therefore, under the action of the arc-shaped air bag 252, the high-performance aluminum alloy sample is fixed more tightly; when the arc-shaped air bag 252 is contacted with the irregular surface of the high-performance aluminum alloy sample, the end parts of the anti-skidding cone blocks 254 uniformly arranged on the surface of the arc-shaped air bag 252 are also contacted with the irregular surface of the high-performance aluminum alloy sample, so that the relative friction coefficient between the arc-shaped air bag 252 and the high-performance aluminum alloy sample is increased, and the high-performance aluminum alloy sample is further fixed; in addition, because the end part of the anti-skid cone block 254 is inclined downwards, when the high-performance aluminum alloy sample moves upwards under the action of the detection equipment, the friction force of the end part of the anti-skid cone block 254 on the high-performance aluminum alloy sample is larger, so that the stability of the high-performance aluminum alloy sample in detection is ensured, and the detection data is more accurate; the cotton cloth 121 arranged on the inner surface of the circular groove 12 has a buffering effect on the high-performance aluminum alloy sample, so that the high-performance aluminum alloy sample is prevented from being in direct contact with the inner surface of the circular groove 12, and the abrasion of the inner surface of the circular groove 12 is reduced; in addition, the wet cotton cloth 121 is beneficial to adsorbing the generated aluminum alloy scraps, and the aluminum alloy scraps are prevented from flying around to enter parts, which are difficult to clean, on the clamping device 2; after the detection is finished, the cotton cloth 121 can be detached for cleaning, and the aluminum alloy scraps on the cotton cloth 121 are completely removed and then installed again, so that the normal function of the cotton cloth 121 is ensured; when cleaning cloth or a scrap removing taper pipe 4 is used for removing aluminum alloy scraps on the upper surface of the supporting platform 1, because the joint part between the blocking block 11 and the upper surface of the supporting platform 1 belongs to a dead angle which is not easy to clean, the aluminum alloy scraps in the middle part of the upper surface of the supporting platform 1 are easy to concentrate under the cleaning action; at the moment, the cleaning cloth or the scrap removing taper pipe 4 can be used for extruding the aluminum alloy scraps at the joint part between the blocking block 11 and the upper surface of the supporting platform 1, so that the aluminum alloy scraps are pressed to enter the scrap removing groove 131 and fall into the first cavity 13 along the scrap removing groove 131, the aluminum alloy scraps at the dead angle which are difficult to clean on the supporting platform 1 are effectively removed, and the cleanness of the detection platform is further ensured;
