Problems solved by technology
[0002] For the tensile test of metal materials with small diameters, it is necessary to clamp both ends of the material during the test, but the material at the fixed end cannot be pinched or clamped, especially for gold wires with a diameter of less than 1 mm. In terms of the clamping test, the requirements are very strict, which requires that there should be no unevenness or gaps after the clamp is closed.
Because the diameter of the gold wire is very small, when the clamp is closed, if there is a gap in the clamp, the gold wire will slip during the test and affect the accuracy and reliability of the test results

Embodiment Construction
[0016] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0017] It should be noted that when a component is referred to as being "mounted on," "fixed to," or "disposed on" another component, it can be directly on the other component or an intervening component may also be present. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
[0018] It should also be noted that the azimuth terms such as left, right, upper and lower in the embodiments of the present invention are only relative concepts to each other or refer to the normal use...

The invention discloses a detection device and an automatic adjustment closing clip. The automatic adjustment closing clip includes two clamping devices, the two clamping devices are hinged on one side and can be opened and closed relative to each other, and the clamping device includes a clip holder and a clip , one end of the clip holder has a spherical hole, one side of the clip has a spherical part adapted to the spherical hole, the spherical part is located in the spherical hole, one side of the clip is connected with one end of the clip holder through a spring, the two clips The other side is opposite to each other, and there is a gap between them for holding the object to be tested. Through the cooperation of the spherical hole and the spherical part, the spherical part can be rotated 360°, so that no matter which point of the clip has uneven contact, the clip can be automatically adjusted in multiple directions such as up, down, left and right, so that the two clips It can be completely closed to clamp the small metal wire, which effectively solves the reliable clamping of the fine metal material, thereby ensuring the accuracy and reliability of the test results.
Description
technical field [0001] The invention relates to the technical field of tensile testing of precious metal materials, in particular to a testing device and an automatic adjustment closing clip thereof. Background technique [0002] For the tensile test of metal materials with small diameters, both ends of the material need to be clamped during the test, but the material at the fixed end cannot be pinched or unable to be clamped, especially for gold wires with a diameter of less than 1 mm The clamping test requirements are very strict, which requires that there should be no uneven clamping and gaps after the clamp is closed. Because the diameter of the gold wire is very small, when the clip is closed, if the clip is not flat and there are gaps, the gold wire will slide during the test process and affect the accuracy and reliability of the test results. [0003] Therefore, the existing technology still needs to be improved and improved. SUMMARY OF THE INVENTION [0004] In v...
