[0002] Metal material testing is an important task, which aims to ensure that the quality and performance of metal materials meet specific standards or requirements. Metal materials are widely used in machinery manufacturing, aerospace, construction engineering, automobile manufacturing and other fields, so the detection of their quality and performance is particularly important. Through testing, defects and problems in materials can be discovered in time to avoid production accidents and safety hazards caused by material quality problems. At the same time, with the continuous advancement of science and technology, metal material testing technology is also constantly innovating and improving.

[0003] The right fixture can help people obtain more accurate data, improve the efficiency and accuracy of detection, and it can also reduce interference from adverse external factors and avoid affecting the test results.

[0004] For example, the Chinese utility model patent document, with the announcement number CN212193040U, discloses a metal material detection fixture, including a rotating fixed protective shell, a rotating load-bearing plate, a metal material detection fixture support frame, a metal material fixing fixture, a fixture telescopic member, a fixture driving rotating member, a height adjustment device, and a load-bearing plate driving device. The utility model belongs to the technical field of metal material detection fixtures, specifically a metal material detection fixture, which can clamp the metal material to be detected, and can flexibly adjust the height and angle according to the size and shape of the metal material, making the clamping more convenient and efficient, and effectively solving the problems of the metal detection fixtures currently on the market being inconvenient to use, unstable clamping, non-adjustable, complex in structure, and inconvenient to maintain.

[0005] However, the existing inspection fixtures are mostly simple in structure. When in use, the overall structure is fixed on the test bench, and most of the overall structures are immovable. In order to provide a better fixing effect, the overall structure is designed to be bulky, and its main function is only to fix metal materials. This is not convenient to use and is quite limited when the operator performs assembly and adjustment.

[0006] In view of this, the present utility model is proposed. Utility Model Content

[0011] Furthermore, in order to increase the stability of the fixation effect, the movable component includes a fixed block and a movable block mounted on the bidirectional screw, the clamping vertical rod is fixed on the movable block, and the fixed block and the movable block are connected by a movable spring. The movable spring is used to press the movable block onto the metal material sample when clamping the metal material, thereby preventing the metal material from falling off.

After the bidirectional screw is clamped on the chuck part, the moving part can be located between the chuck parts on both sides, and then the hydraulic push rod can be started to clamp the metal material, thereby providing a stronger fixing clamping force.
