The utility model relates to a steadily connected steel structure fastener, which comprises a steel beam, a connecting piece and a fastener, through the cooperation of a bolt mounting column and an elastic structure, a person presses a pressing handle to make the lower end of the elastic structure penetrate into a clamping opening, and then the person loosens the pressing of the pressing handle to make a ball move upwards, so that the steel beam is firmly connected. The fastening piece is arranged on the connecting piece and is gradually embedded and pressed to the cambered surface of the inner wall of the clamping opening, so that the lower end of the elastic structure and the clamping opening form a clamping effect, the fastening piece is stably positioned on the connecting piece, the fastening acting force generated by the auxiliary connecting piece on the steel beams is better, the steel beams can be stably connected, and disassembly and assembly are easy.

The utility model discloses a signboard for arbor, including the shell of placing, the both ends fixedly connected with elastic rope of shell of placing, the terminal of elastic rope all fixedly connected with the adjusting band, and a plurality of limit blocks are fixedly arranged on one adjusting band, and the other adjusting band is equipped with at least one snap ring matched with limit block, one end of snap ring is fixedly connected with adjusting band, and the other end is equipped with the clamping block, and the clamping block is detachably connected with adjusting band after passing through snap ring. The utility model discloses signboard need not to be nailed into or rigidly bound, effectively prevent damaging bark and forming layer, and the shell of placing is installed and will not swing with the wind after good, can reduce friction and ring peeling risk, and the convenient dismounting and assembly, convenient maintenance replacement or recycling, realize the non - destructive dynamic identification to the growth of arbor.
