[0028] It comprises a frame 1 and a panel 2, wherein the panel 2 is fixedly mounted on the frame 1; characterized in that it further comprises:

[0029] Slide rail 3, wherein there are two slide rails 3 which are fixedly installed on the rear side wall of panel 2 in a symmetrical manner;

[0030] The movable seat 4 is disposed between the upper and lower slide rails 3, and the upper and lower ends of the movable seat 4 are respectively slidably mounted on the upper and lower slide rails 3.

[0031] Support shaft 5, which is spun onto movable seat 4 via bearings;

[0032] The transmission unit 9 is fixedly mounted on the movable seat 4, and the support shaft 5 is connected to the output end of the transmission unit 9 via a spline.

[0033] A spur gear 10 is fixedly mounted on the input shaft of the transmission unit 9;

[0034] A rack 11 is fixedly mounted on the rear side wall of the panel 2, and a spur gear 10 meshes with the rack 11.

[0035] Support arm 6, which is fixedly mounted on support shaft 5;

[0036] Support pin 16, there are two support pins 16 respectively placed on both sides of the straight rack 11, and the support pins 16 are fixedly set on the rear side wall of the panel 2.

[0037] The drive shaft 7 is spun onto the support arm 6 at the end away from the support shaft 5 via a bearing;

[0038] Indicator sign 8, which is fixedly mounted on the drive shaft 7;

[0039] A shielding cover 15 is fixedly arranged on the supporting arm 6 at the end where the signboard 8 is arranged, and the side edge of the signboard 8 is arranged in the shielding cover 15;
