A rubber pad 208 is fixedly connected to the side of the L-shaped plate 203 near the vertical plate 201, and a rubber pad 209 is fixedly connected to the side of the vertical plate 201 near the L-shaped plate 203. A support wheel 207 is provided on the inner top wall of the L-shaped plate 203, located at the top of the base 1. A support shaft 2016 is rotatably connected to the top of the base 1. A top plate 206 is fixedly connected to the top of shaft 2016. An L-shaped plate 203 is located between the vertical plate 201 and the top plate 206. A movable rod 204 is rotatably connected to the top of the top plate 206. The end of the movable rod 204 away from the top plate 206 is rotatably connected to the top of the L-shaped plate 203. A U-shaped plate 205 is fixedly connected to the end of the connecting column 202 away from the vertical plate 201. The U-shaped plate 205 is fixed to the top of the base 1.

The support ring 2020 is sleeved on the outside of the support shaft 2016 but does not contact the support shaft 2016. Multiple bottom posts 2019 are fixedly connected at equal angles to the bottom of the top plate 206. Each bottom post 2019 has a ball bearing 2018 installed at its bottom end, located on top of the support ring 2020. A guide post 2021 is fixedly connected to the inner side of the U-shaped plate 205. A guide plate 2013 is movably sleeved on the outer side of the guide post 2021. A toothed plate 2014 is fixedly connected to the side of the guide plate 2013 near the support shaft 2016.

When the electric slide rail 302 is energized, it drives the slide block 303 to slide along the electric slide rail 302. Finally, the pressure tester 305 moves horizontally to perform a comprehensive strength test on the display module.
