Specifically, the pin 135 is simultaneously inserted into the first connection hole, the second connection hole, and the mounting hole 1313, and the pin 135 is not located in the via 1315, i.e., the via 1315 functions to provide a passage for the pin 135 to pass through.

One of the bosses 1352 is close to the second connection hole to prevent the pin 135 from falling off from the first connection hole when the pin 135 continues to move toward the second connection hole, i.e., inward.

The above design of the connecting member 13 can prevent the pin 135 from falling off, and the installation of the column 1 is simple.

The folding method of the pillar 1 in this embodiment is as follows:

when the upright post 1 is erected, the positioning block 122 is engaged with the corresponding positioning slot 1314, and the pin 135 is located at the bottom of the mounting hole 1313.

When it is desired to fold the upper upright 12 relative to the lower upright 11, the upper upright 12 is lifted upward to disengage the positioning block 122 from the positioning slot 1314, and then the upper upright 12 is rotated downward toward the notch 133 to make the upper upright 12 perpendicular to the lower upright 11, thereby achieving the folding of the upright.

In other embodiments, the connecting member 13 is provided with mounting holes 1313 on two opposite sides, the pin 135 is inserted into the mounting holes 1313 and the connecting hole 125, and the two ends of the pin 135 are provided with stop blocks. When the upright post 1 is erected, the size of the stop block in the horizontal direction is larger than that of the mounting hole 1313, and then the stop pin shaft 135 falls off. The stop block may be threaded with the pin 135. The pin 135 also enables the upper column 12 to move up and down and rotate with respect to the lower column 11.
