The bracket 100 includes a main rod 10, a key 11, an elastic portion 12 and a plurality of legs 13. The plurality of legs 13 is arranged around an outer circumference of the main rod 10 and rotatably connected to the main rod 10. In this way, when it needs the plurality of legs 13 to be supported, the plurality of legs 13 can be rotated along a forward direction to be unfolded for forming a support structure. After the plurality of legs 13 is completely used, the plurality of legs 13 can be rotated along a reverse direction to be gathered up. The key 11 is arranged on a bottom of the main rod 10 and a first clamping member 131 is formed at a side of each of the plurality of legs 13 that faces the main rod 10. A second clamping member 111 is formed at a portion of the key 11 facing each of the plurality of legs 13 and is engaged with the first clamping member 131 to lock the plurality of legs 13. The key 11 is movably connected to the main rod 10 along an axial direction (a Z direction shown in FIG. 2) of the main rod 10, and is pressed to drive the second clamping member 111 to move, to cause the first clamping member 131 being detachable from the second clamping member 111. The elastic portion 12 is arranged on the main rod 10 and is elastically pressed against a side of each of the plurality of legs 13 that faces the main rod 10 when the plurality of legs 13 is gathered up together.

Specifically, the elastic portion 12 can be elastically pressed against the side of plurality of legs 13 facing the main rod 10 when the plurality of legs 13 is gathered up. The first clamping member 131 and the second clamping member 111 being in an engaged state when the plurality of legs 13 is gathered up, so that the elastic portion 12 can't release its energy. When the key 11 is pressed, thereby causing the first clamping member 131 to disengage from the second clamping member 111, so that the elastic portion 12 is no longer constrained by the first clamping member 131 and the second clamping member 111. Therefore, the elastic portion 12 will release its energy to unfold the plurality of legs 13. That is, it is only to press the key 11, the plurality of legs 13 is automatically pop open, which is very conveniently used, rather than requiring one hand to press the key 11 and the other hand to remove the legs 13 in the related art.

Referring to FIG. 7 and FIG. 8, in a specific embodiment of the present disclosure, the elastic portion 12 includes a base 121 and a plurality of elastic arms 122. The base 121 is arranged on a bottom 101 of the main rod 10, and the plurality of elastic arms 122 is uniformly distributed on the base 121 along a circumferential direction of the main rod 10. One end 12201 of each of the plurality of elastic arms 122 is connected to the base 121, and the other end 12202 of each of the plurality of elastic arms 122 is pressed against the side 1301 of each of the plurality of legs 13 that faces the main rod 10. The plurality of elastic arms 122 is configured to press against the side 1301 of each of the plurality of legs 13 that faces the main rod 10, and the base 121 is integrated with the plurality of elastic arms 122.

Specifically, the base 121 and the plurality of elastic arms 122 integrated with each other can effectively reduce the number of components, which not only reduces complexity of the elastic portion 12, but also lowers assembly and production costs.

Referring to FIG. 7, in a specific embodiment of the present disclosure, each of the plurality of elastic arms 122 includes a connecting portion 1221, a deformation portion 1222 and a crimping portion 1223. One end 12211 of the connecting portion 1221 is connected to the base 121, and the other end 12212 of the connecting portion 1221 extends along a direction away from a top 102 of the main rod 10. The crimping portion 1223 is spaced apart from the connecting section 1221 along a radial direction of the main rod 10, one end 12232 of the crimping portion 1223 connected to the other end 12222 of the deformation portion 1222 and the other end 12233 of the crimping portion 1223 extending towards the top 102 of the main rod 10, wherein the crimping portion 1223 is configured to elastically press against the side 1301 of each of the plurality of legs 13 that faces the main rod 10 when the plurality of legs 13 is gathered up together.

Specifically, because the crimping portion 1223 is spaced apart from the connecting portion 1221 along the radial direction of the main rod 10, so that a deformation space is formed between the crimping portion 1223 and the connecting portion 1221. Therefore, when the plurality of legs 13 is rotated along the reverse direction to be gathered up, the side 1301 of each of the plurality of legs 13 that faces the main rod 10 can press against the crimping portion 1223 to drive the crimping portion 1223 to move close to the connecting portion 1221. At this time, the deformation portion 1222 will undergo elastic deformation, causing the elastic arm 122 to store energy. When the key 11 is pressed, the deformation portion 1222 releases its energy, thereby causing the crimping portion 1223 to move away from the connection portion 1221. Furthermore, because the crimping portion 1223 abuts against the side 1301 of each of the plurality of legs 13 facing the main rod 10, the plurality of legs 13 will pop open when the crimping section 1223 moves, in this way, it does not need to press the key 11 by one hand and remove the plurality of legs 13 by the other hand in the related art, which is very conveniently used.
