As illustrated in FIG. 2, the connector 4 is a flat corner brace and configured to fixedly connect the two adjacent frame borders A1 through screws.

[0040] For convenience of description, as illustrated in FIGS. 3-5, a butt-joint assembly 3 is disposed between the main frame 1 and the auxiliary frame 2, and when the butt-joint assembly 3 is arranged, the elastic member 31 and the adjusting screw 33 are part of the butt-joint assembly 3.

[0041] Specifically, as illustrated in FIGS. 4 and 5, an upper opening of the installation channel 21 is provided with an anti-detachment flange 22, and the anti-detachment flange 22 is configured to prevent the elastic member 31 from completely detaching from the installation channel 21; and the elastic member 31 is a U-shaped elastic sheet provided with a narrow upper half portion and a wide lower half portion, where the upper half portion thereof may disengage from the opening formed by the anti-detachment flange 22, and the lower half portion thereof is confined within the opening formed by the anti-detachment flange 22. The purpose is to prevent the elastic member 31 from detaching from the installation channel 21 when the elastic member 31 is contracted for adjustment.

[0042] Additionally, the U-shaped elastic sheet 31 is provided with a thickened piece 32, the thickened piece 32 is threadedly connected to the adjusting screw 33, and the thickened piece 32 is configured to ensure the reliability of connection between the U-shaped elastic sheet 31 and the adjusting screw 33; and during assembly, one end of the adjusting screw 33 is fixedly connected to or abuts against the lower half portion of the U-shaped elastic sheet 31 (to expand or contract the U-shaped elastic sheet 31), the other end thereof is threadedly connected to the U-shaped elastic sheet 31 and the thickened piece 32, and an opening amplitude of the U-shaped elastic sheet 31 is adjusted by rotating the adjusting screw 33, which enables to further adjust the tightness of press-fit.
