Bonding power vertical tensile test fixture

According to the binding force vertical tensile test fixture, a through groove is formed in the middle of the upper surface of a base, a first pressing piece and a second pressing piece are arranged on the upper surface of the base on the two sides of the through groove, and the distance between the first pressing piece and the second pressing piece is adjustable. The device can be used for vertically pulling up cross samples, and is particularly suitable for fragile samples such as glass which are not beneficial to lap joint shearing stretching or stripping stretching; the device is suitable for testing samples in a larger size range, and the repeated testing and sample changing operation of similar samples is simple.
