[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 object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0017] It should be noted that, when an element is referred to as being “mounted on”, “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. 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 orientation terms such as left, right, up, and down in the embodiments of the present invention are only relative concepts or refer to the normal use state of the produ...

The invention discloses a detection device and an automatic adjustment closing clip thereof. The automatic adjusting closing clip comprises two clamping devices. Two clamping devices are hinged on oneside and can be opened and closed relatively. Each clamping device comprises a clip holder and a clip piece. One end of each clip holder is provided with a spherical hole. A spherical part which matches a spherical hole is arranged in one side of each clip piece, and the spherical part is located in the spherical hole. One side of each clip piece is coupled to one end of a clip holder through a spring. A gap which is used for clamping an article to be tested is arranged oppositely on the other ends of two clip pieces. Through the cooperation of the spherical holes and the spherical parts, thespherical parts can be rotated 360 degrees, and the clip pieces can automatically adjust the directions of upper, lower, left, right and the like no matter which point of the clip pieces is unevenlycontacted. Two clip pieces can be completely closed to clamp a fine wire. A fine metal material is reliably and effectively clamped, and test results are accurate and reliable.
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, 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. [0003] Thereby prior art still needs to improve and improve. Contents of the invention [0004] In view of the deficiencies of the prior...
