Specifically, in this embodiment, as shown in fig. 1, the first fixed side arm 113, the second fixed side arm 114 and the connecting arm 15 enclose a U-shaped structure, and the fixed support portion 11 of the torsion spring 1 can be conveniently fastened and fixed on a fixed component of the apparatus, such as a barrel body of a garbage can, through the U-shaped structure. In some embodiments, as shown in fig. 1, the first fixing side arm 113 and the second fixing side arm 114 may be disposed parallel to each other for facilitating the locking and fixing of the fixing support portion 11, and of course, in some embodiments, the first fixing side arm 113 and the second fixing side arm 114 may be formed to extend away from each other from one end connected to the connecting arm 15 to the other end.
In addition, it should be noted that, in order to facilitate the formation of the first torsion spring body 12 and the second torsion spring body 13, as shown in fig. 1, in the present embodiment, the first torsion spring body 12 is formed by bending an end of the first fixed side arm 113 away from the connecting arm 15 in a spiral shape, and similarly, the second torsion spring body 13 is formed by bending an end of the second fixed side arm 114 away from the connecting arm 15 in a spiral shape, so that the first torsion spring body 12, the second torsion spring body 13 and the fixed supporting portion 11 are integrally formed, thereby improving the rigidity of the torsion spring 1 and enabling the torsion spring 1 of the present embodiment to have a larger rebound performance.
In some embodiments, in order to further improve the resilience of the torsion spring 1, as shown in fig. 1, the first force-applying-side arm 141 is formed by extending an end of the first torsion spring body 12 away from the first force-applying-side arm 141 in a direction away from the connection arm 115. Similarly, the second force applying side arm 142 is formed by extending one end of the second torsion spring body 13 away from the second force applying side arm 142 in a direction away from the connecting arm 15, so that the first force applying side arm 141 and the second force applying side arm 142 can be integrated with the first torsion spring body 12 and the second torsion spring body 13 of the torsion spring 1 respectively, thereby further improving the rigidity of the whole torsion spring 1 and enabling the torsion spring 1 to have better rebound performance.

Example two
A second embodiment of the present utility model is directed to a hinge assembly, as shown in fig. 2, comprising: torsion spring 1, connecting axle 2 as described in the first embodiment.
