The support (1) has a push-pull mechanism (3), and the push-pull mechanism (3) has an outer cover (4) around its outer perimeter. The outer cover (4) has a rectangular through hole (5), and the outer cover (4) has a lower clamping seat (6) fixed to its side wall. The push-pull mechanism (3) has an upper clamping seat (7) through the rectangular through hole (5). The outer cover (4) has a protective cover (9) mounted on it via a hinge (8). The push-pull mechanism (3) includes components fixed to the support (1). The bracket (31) on the bracket (31) has a geared motor (32) fixed on one side wall and a support block (33) fixed on the other side wall. The support block (33) has a guide hole (34). The output shaft of the geared motor (32) passes through the bracket (31) and is fixed with a crank (35). The guide rod (36) that slides up and down is provided inside the guide hole (34). The guide rod (36) and the crank (35) are movably connected by a connecting rod (37). The top of the guide rod (36) is fixedly connected to the upper clamping seat (7) by a mounting seat (38). 2.The flexible OLED screen push-pull test mechanical structure of claim 1, wherein: The upper clamping seat (7) and the lower clamping seat (6) are provided with elastic buffer pads on their respective clamping surfaces. The elastic buffer pads are made of silicone material and have anti-slip textures on their surfaces. 3.The flexible OLED screen push-pull test mechanical structure of claim 1, wherein: The geared motor (32) is a servo geared motor, and the geared motor (32) is electrically connected to the control panel (2) through a driver. The control panel (2) is provided with an adjustment knob for setting the push-pull frequency.

4. The flexible OLED screen push-pull test mechanical structure according to claim 1, characterized in that: A linear bearing is embedded in the inner wall of the guide hole (34), and the guide rod (36) forms a sliding fit with the guide hole (34) through the linear bearing, and the inner ring of the linear bearing is interference-fitted with the guide rod (36).

5. The flexible OLED screen push-pull test mechanical structure according to claim 1, wherein: Both ends of the connecting rod (37) are movably connected to the end of the crank (35) and the middle of the guide rod (36) respectively through spherical bearings, and the outer ring of the spherical bearing is welded and fixed to the connecting rod (37). 6.The flexible OLED screen push-pull test mechanical structure of claim 1, wherein: The outer cover (4) is made of aluminum alloy, and the inner wall of the outer cover (4) is provided with a sound-absorbing cotton layer, which is fixed to the inner wall of the outer cover (4) by adhesive.
