A hold-down mechanism includes a bearing member, at least two hold-down structures arranged on the bearing member, and a locking structure. The hold-down structures are configured to be movable on the bearing member. During testing, each of the hold-down structures is pressed against a unit under test. If the unit under test has an irregular or uneven surface, a distance D between each hold-down face and the bearing member is changed by moving each of the hold-down structures, such that each hold-down face can abut on the surface of the unit under test. Once in abutting, each of the hold-down structures is locked by the locking structure, such that a curved surface formed by joining the various hold-down faces well fits the surface of the unit under test, achieving effective profiling and ensuring that the entire surface of the unit under test is effectively held down.
