Furthermore, a first connection hole 3121 is respectively provided on the two side plates 312, and the two first connection holes 3121 are arranged opposite to each other. In this way, the two first connection holes 3121 are arranged opposite to each other, so that the adjustment screw 32 can pass through the two first connection holes 3121; further, the adjustment screw 32 passes through the two first connection holes 3121 and is connected between the two side plates 312, and the portion of the adjustment screw 32 passing through the two first connection holes 3121 is fixed by a nut, thereby ensuring that the adjustment screw 32 and the adjustment seat 31 are firmly connected. Furthermore, the portion of the adjusting screw 32 located between the two side plates is screwed to the adjusting shaft 33, and the connecting end of the adjusting shaft 33 passes through the adjusting hole 3111 and is connected to the rotating bracket 34; in this way, when the adjusting shaft 33 slides along the adjusting screw 32, the position of the rotating bracket 34 on the adjusting seat 31 can be adjusted. By adjusting the position of the rotating bracket 34, the extending lengths of both sides of the telescopic panel 1 can be made consistent when the telescopic panel 1 moves in the telescopic inner cavity a, thereby preventing the telescopic panel 1 from being skewed in the telescopic inner cavity a, which affects the extension or retraction of the telescopic panel 1 into the telescopic inner cavity a.

Further, the output end of the driving component 4 is connected to the second end of the rotating bracket 34, which is used to drive the rotating bracket 34 to swing, so that the rotating bracket 34 drives the telescopic panel 1 to extend and retract in the telescopic inner cavity a. Specifically, when the telescopic panel 1 is extended or retracted and becomes stuck, the adjusting shaft 33 slides along the adjusting screw 32 to adjust the position of the rotating bracket 34 on the adjusting seat 31. By adjusting the position of the rotating bracket 34, the extension lengths of both sides of the telescopic panel 1 can be made consistent when moving in the telescopic inner cavity a, thereby avoiding the telescopic panel 1 from being skewed in the telescopic inner cavity a, which affects the extension or retraction of the telescopic panel 1 into the telescopic inner cavity a.

[0053] In the description of the present invention, a first feature being “above” or “below” a second feature may include that the first and second features are directly in contact with each other, or may include that the first and second features are not in direct contact but are in contact with each other via another feature therebetween.

In this way, the second end of the rotating bracket 34 is connected to the other end of the second connecting rod 44, and the position of the rotating bracket 34 on the adjusting seat 31 is adjusted by sliding the adjusting shaft 33 along the adjusting screw 32. The position of the second connecting rod 44 can be adjusted by adjusting the position of the rotating bracket 34, so that the extension length of both sides of the telescopic panel 1 can be consistent when moving in the telescopic inner cavity a, thereby avoiding the telescopic panel 1 from being skewed in the telescopic inner cavity a, affecting the extension or retraction of the telescopic panel 1 into the telescopic inner cavity a. Furthermore, the driving member 41 is arranged in the telescopic inner cavity a, and its driving end is connected to the first end of the first connecting rod 42, and the second end of the first connecting rod 42 is connected to the synchronization shaft 43. Through the synchronization shaft 43, the synchronization of the two sides of the telescopic panel 1 when extending or retracting the telescopic inner cavity a can be achieved.
