摘要：
A pair of wedgelike elements are mounted one above the other between a horizontal surface and a rail, with their inclined surfaces abutting each other. One of the wedgelike elements is moved laterally to raise or lower the rail, whereas both elements are moved laterally to cause the rail to move sideways.
