both ends of the longitudinal beam shall be composed of at least five parallel connectors and adjacent longitudinal beams. The sample clamp of the pressure equalizing device has simple structure, uniform pressure and uniform splint pressure. The standardized belt is set in proportion, and the operation is simple. Just tie the belts on both sides of the splint and keep the engraved degree on the same horizontal plane to ensure uniform pressure. One person can complete the sample pressing work.
The splint is composed of cross beam and longitudinal beam, transverse connector and longitudinal connector. The strap fastens the splint by connecting horizontal and longitudinal connectors, which has little impact on the structure of the splint, reduces the pressure of the splint and prevents the deformation of the splint.
