[0026] When in use, in the initial state, the two mounting plates 202 are both in contact with the U-shaped plate 203. At this time, the two guardrails 3 are parallel to each other and are in an unfolded state, which is convenient for protecting the construction site and equipment. When the entire protection frame needs to be transported and transferred, the two guardrails 3 are first rotated to drive the two support columns 201 to rotate, and drive the two mounting plates 202 to rotate until the two mounting plates 202 are in contact with the positioning columns 4. At this time, the two guardrails 3 are perpendicular to each other, and the two guardrails 3 are folded, so as to facilitate the transportation and transfer of the entire protection frame.

[0028] In the use state, in the initial state, the limit rod 2020 is inserted into the limit groove 2015 to support the lifting plate 2012, and the two springs 2011 are in a stretched state. When the lifting plate 2012 moves upward along the U-shaped round rod 2017, the side block 2013 is driven to rise until the limit rod 2020 is disengaged from the limit groove 2015. At this time, the limit rod 2020 rotates 180° under the action of gravity, and then the control of the lifting plate 2012 is released. At this time, the two springs 2011 are reset to drive the lifting plate 2012 to move upward. The plate 2012 moves downward along the U-shaped round rod 2017 and drives the two side plates 2016 to move downward. When the two plug rods 2018 are respectively inserted into the two second holes 206, the two guardrails 3 are unfolded and fixed. When the two plug rods 2018 are respectively inserted into the two first holes 205, the two guardrails 3 are folded and fixed. Then the nuts 2014 are tightened to limit the side blocks 2013 and the two plug rods 2018. Finally, the two mounting plates 202 are firmly fixed.
