1. A bending test device, comprising:
a base; and
at least two carrier components disposed on the base, wherein each carrier component comprises:
a horizontal fixed portion having a first predetermined set of dimensions and fixed in place to the base and
two moving portions having a second predetermined set of dimensions and rotatably connected to two sides of the horizontal fixed portion respectively, each of the two moving portions is configured to rotate freely relative to the horizontal fixed portion, the two sides of the horizontal fixed portion of each carrier component are both supported by a support plate, a flexible sample is fixed on each carrier component, each flexible sample comprises a non-bent portion and bent portions rotatably connected to two sides of the non-bent portion, the non-bent portion of each flexible sample is fixed to the horizontal fixed portion of each carrier component by a first body adhesive fixing member, and the bent portions of the flexible sample are fixed respectively on the two moving portions of each carrier component by both a second body adhesive fixing member and an edge adhesive fixing member;
a support component vertically disposed on the base, wherein one end of the support component is connected to the horizontal fixed portion of each carrier component, the other end of the support component is connected to the base, each of the two moving portions of each carrier component is rotatable around a respective rotation shaft connected between the horizontal fixed portion and each of the two moving portions, and each of the two moving portions is configured to rotate on the respective rotation shaft to a side adjacent to the support component;
a sample fixing member disposed on each carrier component, wherein the sample fixing member comprises a magnetic fixing member; and
wherein the magnetic fixing member is separately disposed on surfaces of the horizontal fixed portion and the moving portions of each carrier component facing towards the support component and surfaces of the non-bent portion and the bent portions of the flexible sample facing away from each carrier component.
