[0040] During assembly, the protruding portion 204 is inserted into the limiting groove 812, and then the damping bracket 002 is connected to the screen housing 801 by bolts.

[0041] Furthermore, a decorative cover 803 is connected to the screen housing 801, and the decorative cover 803 shields the damping bracket 002, the gasket 004 and the fastener 005. Preferably, the decorative cover 803 is provided with a plurality of buckle portions, and the plurality of buckle portions are respectively clamped to corresponding positions on the screen housing 801.
