In one of the embodiments, the secondary hoop body 210 includes two second hoop pieces, and at least one second fracture 213 is formed between the two second hoop pieces. In this embodiment, the secondary hoop body 210 includes two second fractures 213, one of the second fractures 213 is used to engage with the protrusion 121, and the other second fracture 213 has two opposite ends. The walls respectively extend outward to form two opposite second fixing pieces 214. The two second fixing pieces 214 are respectively provided with second connecting holes (not shown), and the second connecting pieces 215 pass through the two in turn. The second connecting hole of the second fixing piece 214 is used to connect the second fixing piece 214 together. When each second fracture 213 is opened, it is convenient to sleeve the secondary hoop body 210 on the pole 30, and then the two second hoop pieces can be locked together by the fastener 220 and the second connecting member 215. The second connecting member 215 is, for example, a bolt, so that the distance between the two second fixing pieces 214 can be conveniently adjusted, so that the width of the second fracture 213 can be adjusted. By adjusting the distance between the two second fixing pieces 214 to be smaller, the secondary hoop body 210 can tighten the pole 30.

In this embodiment, the width of the second fracture 213 corresponding to the second connecting member 215 is greater than or equal to zero. When the width of the second fracture 213 is equal to zero, the gap between the two second fixing pieces 214 is zero. In this embodiment, the width of the second fracture 213 corresponding to the second connecting member 215 is adjustable, and the width can be changed according to the size of the cross section of the pole 30 sheathed by the secondary hoop body 210.

In order to make it easier for the secondary hoop body 210 to be sleeved on the pole 30, in one of the embodiments, the secondary hoop body 210 includes a plurality of second hoop pieces, and the number of the second fractures 213 is at least two. The second fractures 213 are distributed on the secondary hoop body 210 at intervals. Except for the second fractures 213 for mounting the protrusions 121, the side walls of the two opposite ends of the other second fractures 213 respectively extend outward to obtain two opposite second fixing pieces 214, each The two opposite second fixing pieces 214 are respectively connected by a second connecting member 215. In this way, when the secondary hoop body 210 is to be sleeved on the pole 30, each second hoop piece can be separated first, and then the two second hoop pieces are connected to the protrusion 121, and then the second connecting piece 215 All the second hoop pieces are installed on the pole 30, so that each second hoop piece is connected to the auxiliary hoop body 210 that is surrounded by a ring. In one of the embodiments, the secondary hoop body 210 includes a plurality of second hoop pieces, the number of the second fractures 213 is two, one second fracture 213 is used to accommodate the protrusion 121, and one second fracture 213 is correspondingly provided with The second connecting member 215 may be hingedly connected between two adjacent second hoop pieces that are not used to form the second fracture 213.
