Since the second gear 13 is respectively meshed with the first gear 12 and the third gear 14 to rotate, the first gear 12 drives the second gear 13 and the third gear 14 to rotate during the rotation. Since the screw rod 17 and the slider 19 are threadedly connected, the slider 19 is driven to move downward outside the guide column 18 during the rotation of the third gear 14. During the movement of the slider 19, the extrusion plate 11 0 moves downward with it. When the extrusion plate 110 moves downward until it is in contact with the surface of the touch screen placed on the mounting block 111, the touch screen is clamped and fixed on the mounting block 111, thereby reducing the possibility of the touch screen being easily displaced when the touch screen is placed inside the card slot for the bending test, thereby improving the accuracy of the touch screen during the bending test. At this time, the electric push rod 112 can push the pressing block 113 to move downward.

At this time, most of the broken glass fragments of the touch screen will directly fall into the storage block 31. By pulling the second handle 32 to move the storage block 31 to the outside, the staff can quickly clean up the broken glass fragments, thereby improving the overall work efficiency of the staff when cleaning up the broken glass fragments.

When the extrusion plate 110 moves downward until it fits with the surface of the touch screen placed on the mounting block 111, the touch screen is clamped and fixed on the mounting block 111. , thereby reducing the situation that the touch screen position is easily offset when the touch screen is placed inside the card slot for bending test, thereby improving the accuracy of the touch screen during bending test; at this time, the electric push rod 112 can push the pressing block 113 to move downward, and during the downward movement of the pressing block 113, the surface of one end of the fixed touch screen can be bent and pressed; because the transparent protective cover 21 is connected to the first handle 22, at this time, the first handle 22 is pulled to make the transparent protective cover 21 move downward inside the first slide slot 2, and when one end of the transparent protective cover 21 moves downward to the inside of the card slot 24, it stops moving, and a pair of fixing frames 23 can support the transparent protective cover 21 in operation; by setting a fixing frame 23 on the outside of the fixed base 1 The transparent protective cover 21 can reduce the risk of the touch screen glass being broken when the pressing block 113 is bent at one end of the touch screen and the bending angle of the touch screen is large, causing the broken glass fragments to splash out of the test area, thereby avoiding the possible injury to the staff caused by the splashed glass fragments, thereby improving the safety of the staff when performing the touch screen bending test; because the second handle 32 is connected to the placement block 31, at this time, the second handle 32 is pushed to move the placement block 31 through the second slide groove 3 to the bottom of the pressing block 113, at this time, most of the broken glass fragments of the touch screen will directly fall into the placement block 31, and the placement block 31 is moved to the outside by pulling the second handle 32, so as to facilitate the staff The effect of quickly cleaning broken glass debris is improved, thereby improving the overall work efficiency of the staff when cleaning broken glass debris; during the operation of the transparent protective cover 21, the limiting column 42 is inserted into the second limiting hole 41 through the first limiting hole 4, thereby reducing the shaking of the transparent protective cover 21 during operation, thereby improving the overall stability of the transparent protective cover 21 during operation; during the meshing and rotation of the first gear 12 and the second gear 13, the multiple sets of fitting rotating columns 51 follow the rotation, and the multiple sets of fitting rotating columns 51 reduce the long-term rotational friction between the inner side wall of the first gear 12 and the inner side wall of the second gear 13, resulting in a more serious wear on the surface of the first gear 12, thereby improving the working life of the first gear 12;The elastic plate 6 is made of elastic material. When the extrusion plate 110 is used to squeeze and fix the touch screen, the elastic plate 6 first contacts the surface of the touch screen, thereby reducing the situation where the extrusion plate 110 squeezes and fixes the touch screen for a long time, which easily leads to serious wear on the surface of the touch screen; when the slider 19 moves up and down on the outer wall of the guide column 18, the cleaning brush 7 can clean the dust and impurities on the surface of the screw rod 17, thereby improving the cleanliness of the surface of the screw rod 17. ;
