In one embodiment, the outer surfaces of the two resilient arms 32 facing away from each other are recessed and the inner surfaces of the resilient arms 32 are correspondingly raised to form the reinforcement 34. Specifically, the reinforcing portion 34 is integrally press-formed from the outer surface toward the inner surface of the elastic arm 32, so that the molding is facilitated, the number of processing steps can be reduced, and the structural stability of the reinforcing portion 34 on the elastic arm 32 can be ensured. Of course, in other embodiments, the reinforcement 34 may be welded or 3D printed to the resilient arm 32.

In one embodiment, each of the elastic arms 32 further has a first section 321 and a second section 322 connected to each other, the first section 321 is connected to the connecting portion 31, the second section 322 is disposed adjacent to the necking portion 33, a distance between the two second sections 322 is tapered in a direction away from the connecting portion 31, and the reinforcing portion 34 is disposed on the first section 321 and extends to the second section 322. Specifically, the two first segments 321 are disposed substantially in parallel, and the two second segments 322 are disposed gradually closer from the first segments 321 toward the direction away from the connecting portion 31, so that when the elastic arm 32 is deformed by a force, the joint of the first segments 321 and the second segments 322 is the main deformation portion, and the deformation is the largest. The reinforcement 34 extends from the first segment 321 to the second segment 322 along the length direction of the elastic arm 32, which is equivalent to the reinforcement 34 extending from the connection between the first segment 321 and the second segment 322 to the first segment 321 and the second segment 322, respectively, so that the reinforcement 34 can be utilized to a greater extent. In addition, the external dimension of the elastic arm 32 in the arrangement direction of the two second sections 322 can be reduced, so that the gap between the second sections 322 and the hole wall of the mounting hole 13 is increased, and a larger space is provided for the second sections 322 and the necking part 33 to expand and deform outwards.

In another embodiment, the distance between the two elastic arms 32 is tapered in a direction away from the connecting portion 31, and the reinforced portion 34 extends along the length direction of the elastic arms 32. It is also possible to extend the reinforcement portion 34 to the connection portion 31. Of course, in other embodiments, the two elastic arms 32 may be disposed substantially in parallel.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
