[0026] The rotating rod 22 is rotatably connected to the support rod 21 , and the top of the rotating rod 22 is higher than the top of the support rod 21 .

[0027] Specifically, the rotating rod 22 is made to raise the support height of the support rod 21 , and the rotating rod 22 is made to rotate independently inside the support rod 21 .

[0028] A connecting plate 3 is provided between the telescopic seat 4 and the rotating rod 22 . The rotating rod 22 passes through the connecting plate 3 . The top surface of the rotating rod 22 is flush with the top surface of the connecting plate 3 . A bearing 35 is provided at the connection between the connecting plate 3 and the rotating rod 22 .

[0029] Specifically, the connecting plate 3 is fixed to the bottom surface of the telescopic seat 4 , and the rotating rod 22 can rotate independently of the connecting plate 3 through the bearing 35 .

[0030] One end of the connecting plate 3 is provided with a placement slot 31 , and the placement slot 31 is located below the telescopic rod 41 .

[0031] Specifically, the scroll plate is placed through the placement groove 31 , and the placement groove 31 is fixed below the telescopic rod 41 through the connecting plate 3 , so that the center of the placement groove 31 coincides with the center of the workbench 2 .
