A plurality of sliders 40 are all located on the slide rail, so can increase the area of contact of support column 22 and base 10 for the atress is even between support column 22 and the base 10, can improve portal frame 20's stationarity. In this embodiment, only one limiting member 30 may be provided, or a plurality of limiting members 30 may be provided. It can be understood that, since the slide block 40 is first installed on the slide rail, and then the slide seat 222 is installed on the slide block 40, when the position-limiting member 30 is adjusted, the slide seat 222 actually moves relative to the slide block 40, so that the position-limiting surface 2222 abuts against the slide block 40. When one stopper 30 is provided, the sliding seat 222 moves to make the stopper surface 2222 abut against the side surface of the slider 40 at the same time.

Certainly, in order to ensure that the plurality of sliders 40 can be well abutted against the limiting surface 2222, in this embodiment, two limiting members 30 are disposed on the supporting column 22, and the two limiting members 30 are respectively disposed corresponding to the sliders 40 located at two outer sides of the plurality of sliders 40. Specifically, the two limiting members 30 are distributed along the arrangement direction of the plurality of sliders 40, and the two limiting members 30 are respectively disposed corresponding to the two outer sliders 40. Because a plurality of sliders 40 on the same support column 22 all locate a slide rail on, so fix the back with the slider 40 in two outsides through locating part 30, also can the slider 40 between the slider 40 in two outsides and spacing face 2222 butt, so can guarantee that a plurality of sliders 40 all better with spacing face 2222 butt, can reduce the quantity of locating part 30, reduce installation time and cost.
