[0002] Edge protection is a device used to prevent construction workers from falling from the edge during construction. It is generally installed in the form of fences and steel pipe suspension. When fences are used for edge protection, the installation process of the fence is complicated and slow. Generally, only the bottom of the fence is anchored inside the floor slab, and the strength is low and the safety of protection is not high. If steel pipe suspension is used, it is necessary to install hangers for hanging steel pipes at both ends of the wall of the edge protection, which consumes manpower and slows down the construction. Existing edge protection devices generally use a screw structure. This type of edge protection device is heavy and requires several people to lift the device to a certain height during installation; several people are also required to cooperate during disassembly. Each high-rise building will be installed with a large number of edge protection devices. If manual disassembly is used, it will not only be labor-intensive and delay the construction period, but also more likely to cause safety problems.

[0003] Therefore, a kind of edge protection device that can be installed and disassembled by oneself is needed. Summary of the invention

Telescopic rod A and telescopic rod B can be rotated to the left and right sides respectively, so as to fold or unfold the device.

[0008] Furthermore, the motor is divided into motor A and motor B, motor A drives telescopic rod A and telescopic rod B through gears, and motor B drives telescopic rod C through gears. Telescopic rod A and telescopic rod B can rotate synchronously through gears, which can simplify the device and make the structure more stable; at the same time, telescopic rod C can be controlled separately, which has a wider range of usage scenarios.

[0011] Furthermore, the top pressure end plate is a square nail plate. The square nail plate can pierce the tip into the wall to prevent the device from slipping and causing unstable protection, which may cause safety hazards.

[0012] Furthermore, a ratchet and a limiter are provided at the connection between the driving motor and the screw rod; the limiter includes a housing, a wedge-shaped stopper and a spring provided inside the housing; the ratchet and the limiter are used to lock the stud to prevent the stud from rotating due to the compression of the telescopic rod, thereby causing the pre-tightening force to be unable to be applied.
