[0017] See Figures 1 to 5 This utility model relates to an online display screen replacement instrument, a 96-function instrument, which includes a housing composed of a panel 1, a base 3, a frame 6, and a rear shell 7. A push rod 4 is installed in the base 3, allowing rotation from the side to the vertical. The panel 1 is fastened to the front of the base 3 via the frame 6, and the rear shell 7 is fastened to the back of the base 3. The frame 6 and the rear shell 7 are assembled using sliding fasteners. The display screen 2 is placed in the base 3, which has a clamping device inside to hold the pins of the display screen 2 in place. When the push rod 4 is moved to the side position, it can limit the movement of the display screen 2 inside the base 3. The 96-function instrument is installed on the door panel of an electrical cabinet. A 91*91 square hole is opened in the electrical cabinet door, allowing the instrument to be pushed in from the front of the door. The outer side of the rear shell 7 is fixed to the back of the cabinet door via a fixing bracket 5.

[0018] The process of replacing the display screen online is as follows: pry the upside-down position of panel 1 and frame 6 with a flathead screwdriver to remove panel 1. At this time, open the push rod 4 to the vertical position, take out the display screen 2 for replacement, install the new display screen, press the push rod 4 down, clamp the pins of display screen 2 inside the base 3, and then cover panel 1. This completes the online replacement of the display screen instrument.

[0019] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
