[0002] Building construction refers to production activities during the implementation phase of engineering construction, and is the process of building various types of buildings. During the construction process, protective nets are needed to protect the safety of construction workers. However, the current construction engineering construction protective devices are more difficult to adjust when adjusting the height of the protective net according to different construction requirements. It is necessary to manually slide back and forth to adjust the length of the two support columns, and then fix them with fixing bolts. The adjustment and installation are more troublesome, which reduces the efficiency of the installation work. Therefore, an adjustable protective device is needed.

[0003] The Chinese utility model patent with publication number CN214330231U discloses an adjustable construction engineering protection device.

By setting a main buckle and a secondary buckle, by pressing a button, the button drives the pressing rod to move, and the pressing rod drives the transmission rod to move. When the transmission rod moves to the appropriate position, the insertion rod can freely enter and exit the groove, so as to achieve the purpose of quickly installing or replacing the protection net.

[0004] However, in the above patent, after the positions of the telescopic column and the support column are adjusted by placing round holes, screw holes and threaded rods, the round holes and screw holes are overlapped, and the threaded rods are aligned with the screw holes and inserted. It is necessary to manually slide back and forth to adjust the length of the two support columns, and then fix them with fixing bolts. The adjustment and installation are more troublesome, which reduces the efficiency of the installation work. Utility Model Content
