Description

Technical Field

[0002] In order to solve the problem of "it is inconvenient to stably press and limit the touch screen during the detection process", the Chinese patent with publication number CN221685477U discloses a deformation detection device for anti-deviating touch screen production, including a detection table, a base groove is opened in the detection table, and two limit plates that abut the touch screen are symmetrically installed on the top of the detection table. The adjacent sides of the two limit plates are equidistantly rotatably installed with multiple limit cylinders embedded in the limit plates. One end of the two limit plates is slidably connected to a long rod, and the other ends of the two long rods are threadedly connected to a screw rod. Although the existing technical problems have been solved, the following problems still exist:

[0003] When the touch screen is compressed and deformed again, it will gradually form a V shape, that is, the middle part of the touch screen bends downward, and the two end parts are tilted upward, so that the two end parts will also approach each other. Therefore, the touch screen is dynamic in this process, and the receiving device and the sliding device that play a fixing role in the technical solution cannot approach each other, so it will cause relative sliding between the touch screen and the sliding device, thereby causing wear to the touch screen. Therefore, corresponding improvements are made to address this problem. Summary of the invention
