[0025] A pulley 606 is rotatably connected to both sides of the outer wall of one end of the mounting plate 1 . The two pulleys 606 are coaxially fixed to one end of the two bidirectional screw rods 602 , respectively. The two pulleys 606 are sleeved with the same connecting belt 607 .

[0026] A pulley 606 is driven to rotate by the handle, and this pulley 606 can drive another pulley 606 to rotate in the same direction through the connecting belt 607, and then the two bidirectional screw rods 602 are driven by the two pulleys 606 to rotate at the same time, and the two supporting assemblies 6 will also operate at the same time. The two moving blocks 603 restricted by the mounting plate 1 can be driven by the bidirectional screw rods 602 to move away from each other, and one end of the two connecting rods 604 will move synchronously with the moving blocks 603, and then the support plate 605 will be farther and farther away from the mounting plate 1, and the supporting area of ​​the device will also increase accordingly.

[0027] like Figure 1 and Figure 2 As shown, vertical plates 3 are fixedly connected on both sides of the top outer wall of the mounting plate 1, multiple slide rods 4 are slidably inserted into the top outer walls of the two vertical plates 3, and one end of the top of the multiple slide rods 4 on one side is fixedly connected to the same mounting block 5, and fixing components 7 are installed inside the two mounting blocks 5.
