The first support rod is sleeved outside the second support rod, an overlapping part is arranged between the first support rod and the second support rod, and when the first support rod is in sliding connection with the second support rod, the length of the overlapping part between the first support rod and the second support rod is changed: the longer the overlap length, the shorter the overall length of the brace. Thus, the whole length of the supporting rod can be adjusted by adjusting the relative positions of the first supporting rod and the second supporting rod. When the length of the supporting rod is adjusted to the ideal length, the first supporting rod and the second supporting rod are fixed, so that the first supporting rod and the second supporting rod form a whole.

As shown in fig. 9 and 10, the through hole 101 on the support rod includes a first through hole 1011 on the first support rod 103 and a second through hole 1012 on the second support rod 104, and the first through hole 1011 and the second through hole 1012 are respectively plural. When the first supporting rod 103 and the second supporting rod 104 are fixed relatively, the first supporting rod 103 and the second supporting rod 104 have an overlapping portion, and the first through hole 1011 and the second through hole 1012 of the overlapping portion are aligned. Thus, the plug pin can be inserted into the support rod through hole at the overlapping part of the first support rod and the second support rod, and the plug pin needs to pass through the first through hole and the second through hole at the same time.

In some embodiments, for example, as shown in fig. 9, the first supporting rod 103 includes a first bottom plate 1031, the first through holes 1011 are disposed on the first bottom plate 1031, and the first limiting plates 1032 are disposed on the left and right sides of the first bottom plate 1031, respectively, and when the first supporting rod 103 is sleeved outside the second supporting rod 104, the second supporting rod 104 is located between the two first limiting plates 1032. The first strut is shaped like a through slot. If the first supporting rod is only formed by the first bottom plate, when the first supporting rod and the second supporting rod are connected through bolts, the first supporting rod and the second supporting rod are easy to rotate relatively around the bolts, so that the whole supporting rod is bent. When the first support rod is sleeved outside the second support rod, the first support rod and the second support rod rotate relatively around the bolt, so that the support rod can maintain good verticality in the use process. In some embodiments, the first stopper plate 1032 is perpendicular to the first bottom plate 1031.

In some embodiments, for example, as shown in fig. 9, a first screw hole 1033 is provided on the first limiting plate 1031. The central connecting line of the first screw holes 1033 on the two first limiting plates is perpendicular to the axis of the first bottom plate 1031. As shown in fig. 10, the second strut 104 includes a second bottom plate 1041, and the second through holes 1012 are disposed on the second bottom plate 1041; the second limiting plates 1042 are disposed on opposite sides of the second bottom plate 1041. The second limiting plate 1042 is provided with a second screw hole 1043 aligned with the first screw hole 1033, as shown in fig. 11, for example. Two or more second screw holes 1043 are formed in each second limiting plate 1042. The second limiting plate 1042 is perpendicular to the second bottom plate 1041. The second support rod is similar to a through groove in shape. When the first support rod is sleeved outside the second support rod, the first bottom plate is parallel to the second bottom plate, and the first limiting plate is parallel to the second limiting plate.

When the length of the support rod is adjusted, the first support rod is sleeved outside the second support rod, so that the second screw hole is aligned with the first screw hole, and then a bolt is sequentially inserted into the first screw hole on the left side of the first support rod, the second screw hole on the left side of the second support rod, the second screw hole on the right side of the second support rod and the first screw hole on the right side of the first support rod; the bolt is exposed from one end of the first screw hole on the right side of the first supporting rod, and a nut is sleeved on the exposed end of the bolt and screwed down to realize the relative fixation of the first supporting rod and the second supporting rod. The second screw holes with different heights are aligned with the first screw holes, so that the length of the support rod is adjusted.
