Description

Technical Field

[0001] The utility model relates to the technical field of flag-shaped sample holders, in particular to a square flag-shaped sample holder clamp. Background Art

[0002] Flag-type sample holders are widely used in the field of surface analysis. The basic design of flag-type sample holders usually includes a load-bearing end and a grabbing part. The load-bearing end is used to support and fix the sample to be analyzed, while the grabbing part is used to install the sample holder in the analysis equipment.

[0003] At present, when processing square flag-shaped sample holders, they need to be clamped and fixed with a clamp. The existing clamp can only clamp and fix one sample holder, which is time-consuming and labor-intensive. The clamp structure is relatively simple and it is not easy to control the strength. If the clamp is too tight, the sample holder may be easily damaged. If the clamp is too loose, the square flag-shaped sample holder may easily fall due to shaking during the mobile processing, causing damage. Therefore, it is necessary to provide a square flag-shaped sample holder clamp to solve the above problems. Utility Model Content
