[0030] Reference Figure 2 and Figure 4 The top surface of the connecting plate 6 is also equipped with a sleeve 8 for being sleeved on the push rod 5. The outer wall of the sleeve 8 is also provided with two avoidance grooves 24 for the limit pin 11 to pass through. The sleeve 8 is made of metal material. When used, it can further increase the stability of the connecting plate 6 in actual use, so that it is not easy to shake.

[0031] Reference Figure 1 and Figure 3 A pair of moving rods 25 are fixed on one side of the two clamps 22, and the moving rods 25 pass through the U-shaped moving frame 20; this can increase the stability of the clamps 22 when moving, making it difficult to shake easily.

[0033] Reference Figure 1 One side of the two clamping plates 22 is glued with a rubber pad to avoid wear and scratches that may occur when clamping the mobile phone screen.

[0034] The implementation principle of a mobile phone screen pressure testing mechanism in the embodiment of the present application is as follows: when in use, first, when it is necessary to install the connecting plate 6, the pull rod 13 can be pulled outward and flipped, and then the pull rod 13 can be hung on the limit rod 14. At the same time, the reset spring 17 will be squeezed by the fixing plate 16 to shrink it, and then one end of the limit pin 11 is aligned with the position of the positioning groove 9, and the pull rod 13 is pulled and flipped again to make it detach from the limit rod 14. At this time, the reset spring 17 will quickly restore its deformation and push the fixing plate 16 to reset, thereby driving the pull rod 13 to reset. When the connecting plate 6 is removed, the limit pin 11 is inserted into the positioning groove 9, so that the connecting plate 6 can be fixed on the pushing rod 5. At the same time, there is a limiting effect between the limit pin 11 and the positioning groove 9, thereby preventing the connecting plate 6 from shaking. Through the above steps, the connecting plate 6 can be stably installed on the pushing rod 5, which is convenient to operate and easy to use. When the connecting plate 6 needs to be removed, it is only necessary to pull the pull rod 13 outward and flip it, and the pull rod 13 can be hung on the limit rod 14, so that the two limit pins 11 can be disengaged from the inside of the positioning groove 9. At this time, the connecting plate 6 can be removed.

[0035] When testing the collection screen, the mobile phone screen can be placed on the U-shaped moving frame 20, and then the cylinder 4 is started. The output end of the cylinder 4 pushes the push rod 5 to move downward, and the push rod 5 drives the connecting plate 6 and a plurality of pressing rods 7 to move downward together. When the bottom end of the pressing rod 7 contacts the mobile phone screen to be tested on the working plate 1, the push rod 5 is continuously pushed so that the pressing rod 7 applies a certain pressure to the mobile phone screen to test the pressure resistance of the mobile phone screen. During the test, the positions of the two moving blocks 21 on the guide rod 19 can be adjusted as needed to change the positions of the U-shaped moving frame 20 and the pressing rod 7, so as to adapt to mobile phone screens of different sizes.

[0036] During testing, the connecting plate 6 can be removed from the push rod 5 through the quick-release assembly, which not only facilitates the replacement or repair of the pressing rod 7, but also allows the connecting plate 6 with different numbers of pressing rods 7 to be easily replaced. This design not only improves the flexibility and compatibility of the equipment, but also improves the test efficiency and accuracy.
