[0028] Furthermore, two groups of extension rods 2 are provided, and the two groups of extension rods 2 are installed on both sides of the platform 11, and the number of extension rods 2 in each group is two. The two ends of the connecting rod 21 are fixedly connected to the surface of the extension rod 2, and the connecting rod 21 is movably connected to the surface of the movable groove 22. Under the connection of the connecting rod 21, pulling the connecting rod 21 can simultaneously drive the extension rods 2 on both sides to move together inside the base frame 1.

[0029] Furthermore, the surface of the sleeve 23 is a regular hexagon, and two groups of through holes 24 and sockets 25 are provided. The two groups of through holes 24 are opened on both sides of the base frame 1, and the two groups of sockets 25 are opened on both sides of the extension rod 2. The diameter of the socket 25 is the same as the diameter of the through hole 24. Under the action of the sleeve 23, the bolt 26 can be limited to avoid the bolt 26 being driven to rotate together when the nut 27 is installed, causing inconvenience in tightening, and the through holes 24 are distributed in a linear array on the surface of the base frame 1.

[0030] Furthermore, the bolt 26 is inserted and connected to the surface of the through hole 24 and the socket 25, the bolt 26 is snap-connected to the inner surface of the sleeve 23, one end of the bolt 26 is abutted and connected to the surface of the base frame 1, and the other end of the bolt 26 is threadedly connected to the surface of the nut 27, and the nut 27 is abutted and connected to the surface of the base frame 1.

The magnetic properties of the contact surfaces of the first magnet 36 and the second magnet 37 are different. When they are close together, they are attracted by opposite charges and then adsorbed together.

[0034] Working principle: When adjusting the height of the clean workbench, first remove the bolt 26 and the nut 27 from the base frame 1 through the thread, then pull the connecting rod 21 to drive the extension rods 2 on both sides to slide along the inner surface of the base frame 1, and the connecting rod 21 slides on the surface of the movable groove 22, and aligns the hole 25 with the through hole 24 at the corresponding position according to the height of the staff. At this time, insert the bolt 26 from the side of the sleeve 23 into the through hole 24 and the socket 25, and make the bolt 26 engage with the inner side of the sleeve 23, and then connect the nut 27 to the bolt 26 through the thread and press it against the surface of the base frame 1 after tightening to complete the height adjustment of the clean workbench.

[0035] When the clean bench is not used, first move the two groups of movable plates 3, and make the movable plates 3 pass through the rotating groove 32 and rotate to the inner side of the rack 11 with the rotating rod 34 as the center, when the second magnet 37 and the first magnet 36 approach each other, they are adsorbed together due to the principle of attracting each other of different magnets, and then the two groups of movable plates 3 can be attached to the surface of the rack 11, so as to cover the opening of the rack 11 and achieve the dustproof effect.
