When the position of the frame body 3 needs to be fixed, the bolts 11 are tightened to increase the friction, so that the frame body 3 is stable and immovable; when the frame body 3 needs to be moved, the bolts 11 are loosened to reduce the friction, so that the frame body 3 is conveniently pushed along the sliding rail by a tester.
