[0022] As Figures 1-4 The utility model discloses a test tool of foldable display screen, including the base frame 1, and the base frame 1 is fixedly connected with the supporting plate 2, and the base frame 1 is rotatably provided with two groups of pivot 3, and the pivot 3 and the base frame 1 are provided with folding device 4, and the folding device 4 is provided with auxiliary fixing device 5 to assist fixing folding screen in the process of folding, and the top of base frame 1 is provided with compression device 6 to press folding screen and prevent folding from warping upwards, folding device 4 includes gear 9, gear 9 is fixedly connected on pivot 3 and is engaged with each other, and the bottom of base frame 1 is fixedly connected with electric push rod two 8, and the output end of electric push rod two 8 is connected with rack 10 and is engaged with one of gear 9, and the lower end surface of supporting plate 2 is fixedly connected with guide plate 11, and guide plate 11 is downwardly arranged in rack 10, and the end of pivot 3 is fixedly connected with folding groove 7, by placing folding screen in folding groove 7, rack 10 engages gear 9 and rotates, and the gear 9 on both sides can drive folding groove 7 to fold inwards synchronously, so that the folding test of folding screen can be realized.

[0023] As Figure 1 And 3 Auxiliary fixing device 5 includes support 12, and support 12 is across the upper end of folding groove 7, and the top wall of support 12 is fixedly connected with electric push rod three 13 downward, and the output end of electric push rod three 13 is connected with frame 14, and the upper end surface of frame 14 is fixedly connected with two groups of guide rod two 19, and guide rod two 19 is symmetrically arranged with electric push rod three 13, and compression roller 15 is rotatably arranged in frame 14 and located in folding groove 7, when folding screen is placed in folding groove 7, frame 14 is pushed by electric push rod three 13, and compression roller 15 can assist pressing folding screen, so that it can be guaranteed that folding screen does not deviate and fall off in the folding process, and the test continuity is maintained.

[0024] As Figure 1The pressing device 6 includes an electric push rod 16, which is fixed to the top of the base frame 1. The output end of the electric push rod 16 is connected to a pressing plate 17. The upper end of the pressing plate 17 is symmetrically provided with two sets of guide rods 18 on the electric push rod 16, and the guide rods 18 extend upward through the base frame 1. By pressing the pressing plate 17 onto the folding screen, the folding screen can be folded smoothly.

[0025] like Figure 1 The pallet 2 is equipped with a control center 20, which is connected to the electric push rod 16, the electric push rod 28 and the electric push rod 313 via electrical control signals.

[0026] In practical use, the screen to be folded is first placed in the folding groove 7, which is in a horizontal state. Then, the frame 14 is pushed down by the electric push rod 13, so that the pressure roller 15 presses on the folding screen.
