FRONT MAINTENANCE TOOL FOR DISPLAY SCREEN

摘要

A front maintenance tool for a display screen, comprising a mounting housing (10), an air suction assembly (20), a suction cup (30), several compressing blocks (41), and several driving members (50); a mounting cavity (11) having an opening is provided on the mounting housing (10), the suction cup (30) is mounted in the mounting cavity (11) and seals the opening, the air suction assembly (20) is mounted in the mounting housing (10) and is connected to the suction cup (30) in a sealed manner, and several grooves (31) extending out of the sides of the suction cup (30) are provided on the suction surface of the suction cup (30); the compressing blocks (41) are mounted in the mounting cavity (11), abut against the back surface of the suction cup (30), and directly face the grooves (31); and the driving members (50) are mounted on the mounting housing (10), directly face the compressing blocks (41), and are used for pushing the compressing blocks (41) to press the back surfaces of the grooves (31). Pressing the grooves adjusts a vacuum suction force, thereby satisfying the front maintenance requirements of display screens having different pitches.
