[0039] The second frame portion (210) may be formed in the shape of a rod or bar having a set length. The second frame portion (210) may be formed in a curved shape having a set curvature. The second frame portion (210) may be formed with a cross-section that is approximately semicircular.

[0040] The second frame part (210) may be manufactured using a plastic material that has excellent strength, is lightweight, and is capable of elastic deformation. The second frame part (210) may be positioned on the outside of the utility pole (10) without contacting the utility pole (10), spaced apart from the utility pole (10), and positioned opposite the first frame part (110).

[0041] At each free end of the second frame part (210) facing the first frame part (110), a second protrusion (211) that contacts the first protrusion (111) may be provided. The second protrusion (211) may be formed to protrude in the longitudinal direction of the second frame part (210). The thickness of the second protrusion (211) may be formed to be thinner than the thickness of the second frame part (210).

[0042] A second magnet (211a) may be provided on the inner surface of the second protrusion (211) that contacts the inner surface of the first protrusion (111). The second magnet (211a) may be provided on the inner surface of the second protrusion (211) in a non-protruding state.

[0044] The second magnet (211a) may have a polarity of the N pole opposite to that of the first magnet (111a). Of course, if the polarity of the first magnet (111a) is the N pole, the second magnet (211a) may have a polarity of the S pole.

[0045] The second net (220) is a member upon which falling objects land and can be formed to have a breathable mesh structure. The second net (220) can be made of a fabric or plastic material.

The second connecting member (221) may be formed to have a Velcro structure. In addition to the Velcro structure, the second connecting member (221) may be formed to have a structure such as a snap button or a zipper.

[0048] The second band portion (230) is located on the lower side of the second frame portion (210). The second band portion (230) may be spaced apart from the second frame portion (210). The second band portion (230) is connected to the other side of the second net (220), wraps around the remaining part of the outer surface of the utility pole (10), and can be detachably connected to the first band portion (130). Here, the other side of the second net (220) refers to the lower edge of the second net (220).

[0049] The length of the second band portion (230) may be formed to be shorter than the length of the second frame portion (210). Accordingly, the second net (220) is arranged in an inclined shape, so that the second fall prevention portion (200) can be formed in the shape of an inverted trapezoid.

[0050] The pole-mounted falling object prevention device (1) of the present invention can be formed to have a slanted structure that is wider at the top and narrower at the bottom, with the diameter gradually decreasing from the top to the bottom.

[0051] The second band portion (230) may be manufactured including an elastically deformable material. Additionally, the second band portion (230) may be formed in a stretchable shape. The second band portion (230) may be formed to have a Velcro structure.
