[0018] Preferably, both ends of the movable plate 5 are slidably connected to two first slide grooves 41, wherein a first screw 42 is rotatably arranged in one of the first slide grooves 41, the first screw 42 penetrates the movable plate 5 and is screwed to the movable plate 5, and a first motor 43 for driving the first screw 42 to rotate is installed on the support plate 4. A second screw 52 is rotatably arranged in the second slide groove 51, the second screw 52 penetrates the fixed end of the telescopic machine 6 and is screwed to the fixed end, and a second motor 53 for driving the second screw 52 to rotate is installed on the movable plate 5.
[0019] The cross bar 21 is provided with a side sliding groove 22 that runs through the front and rear of the cross bar 21 and a limiting groove 25 that runs through the top and bottom of the cross bar 21. The adsorption column 3 is slidably connected to the limiting groove 25. The front and rear sides of the adsorption column 3 are fixedly connected with sliders 31. One end of the slider 31 is connected to the adsorption column 3, and the other end is provided with a threaded column, and a fixing piece 32 is screwed on the threaded column.
