Description

Technical Field

[0001] This utility model relates to the field of biological sample clamping devices, and in particular to a fixing base that facilitates clamping biological samples. Background Technology

[0002] Currently, traditional biological sample holders have many problems that need to be solved in practical applications. For example, in terms of sample clamping, traditional holders often have difficulty in providing stable fixation of samples from all directions.

[0003] For securing the sample above the sample, traditional structures often lack effective abutment and fixation methods, resulting in unstable fixation and easy shaking. This not only affects the stability of the sample during the detection process but may also lead to inaccurate detection data due to sample shaking. For fixing the sample on both sides, the positioning structure of traditional fixtures is not precise enough to achieve accurate clamping and fixation of the sample, thus affecting the accuracy of sample positioning. For fixing the sample at the bottom, traditional methods often use simple support structures, which are prone to instability and sample displacement during experimental operations. Furthermore, in terms of adjusting the position of the fixture, the movement of traditional fixtures in the X and Y axes is often not smooth enough, and the movement accuracy is insufficient to meet the needs of modern biological experiments. This makes precise adjustment of the sample position difficult, reducing the flexibility and precision of experimental operations. At the same time, traditional fixtures have poor adaptability to tabletops of varying flatness, making it difficult to place stably on uneven surfaces, affecting the usage scenarios of the fixture and the smooth progress of experiments. Therefore, improvements are needed to address these issues. Utility Model Content

[0023] In this invention, the lower end of the base 1 has multiple longitudinally spaced replacement slots 11, which facilitate the installation and replacement of the telescopic block 13. The upper end of the base 1 has a transverse first sliding groove 12, through which the bottom end of the first sliding platform 2 is slidably connected to the base 1, facilitating smooth sliding between the first sliding platform 2 and the base 1. Furthermore, the first sliding platform 2 and the base 1 are connected via the first sliding groove 12 to mount a first screw 19, which engages with both the first sliding platform 2 and the base 1 for transmission.
