Regulate the position of said bearing fixed seat on holder for ease; Said holder is L-shaped; The one of which end has adjustment hole, and a side of said bearing fixed seat has first threaded hole, and said bearing fixed seat is fixed on the said adjustment hole through regulating the bolt and first threaded hole.
Further improve technique scheme, be provided with pad between said rotation nut and the spring.
Stability when clamping the notebook computer liquid crystal screen in order to increase said intermediate plate; These anchor clamps comprise two screw rods and two linear bearings; Said two screw rods are parallel to each other; Be respectively arranged with a linear bearing on the smooth end of said two screw rods, said two linear bearings vertically are fixed on the bearing fixed seat, and the termination of said smooth end has second threaded hole; One end of said intermediate plate has two circular holes, and said intermediate plate is fixed on the termination of said smooth end through set bolt, circular hole and second threaded hole.
Be clamped between said intermediate plate and the external part for the liquid crystal display that makes notebook computer is stressed moderately; Be provided with link stopper between said intermediate plate and the bearing fixed seat; Have on the said link stopper and the corresponding through hole of circular hole, said intermediate plate and block are fixed on the termination of said smooth end through set bolt, circular hole, through hole and second threaded hole.
Further, the other end of said holder is fixed on the swinging mounting of rotating shaft torsion durability-testing machines through screw.
The present invention compared with prior art; Its beneficial effect is: the anchor clamps that are used for the rotating shaft testing fatigue of the present invention, and simple in structure, easy to use; It can close screen when the test rotating shaft fully; Promptly can the screen zero degree of notebook etc. is closed, and can clamp screen, the clamping dynamics of simulation staff.
