Outer flange parts protrude outward from both sides of the outer flange relative to both sides of the middle convex part. A second T-shaped track groove perpendicular to the vertical plate is provided on the middle outer side of the middle convex part of the first T-shaped slider part of the third pen holder assembly. A second limiting part is provided at the outer end of the second T-shaped track groove. The second T-shaped track groove includes a front section area and a rear section area. The front section area of the second T-shaped track groove is directly a T-shaped groove hollowed out in the middle of the middle convex part, and the rear section area of the second T-shaped track groove is formed by removing the outer flange plate on the basis of the hollowed-out T-shaped groove. As Figure 10 shown, a second inner sliding groove for movably sleeving the first telescopic section is provided in the second telescopic section.
