The two plates extend horizontally to the bottom in the direction of approaching each other, but the ends are not in contact (i.e. forming a gap). So arranged, a receiving space is defined between the first plate 2 and the second plate 3 so that the pulley of the column can be mounted therein. The horizontally extending sections of the bottoms of the two plates may provide support for the pulleys so that the pulleys may move in this space. In this way, a rail-like structure is formed by the first and second plate-like structures extending from the body 1, so that the sliding uprights can be mounted on the profiles without additional guide members. Of course, the distance between the first plate 2 and the second plate 3 is designed according to the practical use of the column pulley, and if the width of the pulley is larger than that of the main body 1, an extension section can be formed by horizontally extending the left side of the bottom of the main body 1 to the left as shown in fig. 1, and the first plate 2 is connected to the bottom of the extension section. Thus, the transverse size of the main body 1 does not need to be too large, and the installation requirement of the sliding upright post can be met. As shown in fig. 2, the pulley 101 of the sliding column 102 is a longitudinal wheel, which is located in the space between the first plate 2 and the second plate 3.
