[0028] Furthermore, in other preferred embodiments of the present invention, the negative pressure mechanism 20 includes a vacuum machine 210 , and the elastic plate 10 is provided with a first through hole 102 , and the first through hole 102 is connected to the air suction hole 2101 of the vacuum machine 210 .

[0040] Furthermore, a second elastic member 1102 is provided in the first cavity 101 .

[0041] Specifically, a plurality of second elastic members 1102 are arranged at intervals in the first cavity 101, so that when the elastic plate 10 is adsorbed on the display module, a certain distance can be maintained between the middle of the elastic plate 10 and the display module to prevent the elastic plate 10 from hitting the lamp beads of the display module and damaging the lamp beads, thereby improving the safety of the display screen maintenance tool.

[0044] Furthermore, an elastic ring 402 is provided between the elastic plate 10 and the mounting plate 40, wherein the size of the elastic ring 402 is larger than the size of the first through hole 102 and the second through hole 401, that is, the elastic ring 402 is arranged outside the first through hole 102 and the second through hole 401. The provision of the elastic ring 402 can improve the sealing performance between the vacuum machine 210, the exhaust hole 2101, the second through hole 402, the first through hole 102 and the first cavity 101, and helps to quickly evacuate the first cavity 101 so that the elastic plate 10 can be quickly and firmly adsorbed on the display module.
