Further, the tip portion of the free end 5 exceeds the projecting portion of the first engaging member 7, and the end face of the slot 6 on the side of the insertion end 3 is flush with the end face of the first engaging member 7. Specifically, since the notch 6 is provided between the first engaging member 7 and the second engaging member 8 on the elastic sheet 2, in order to protect the first engaging member 7 and the second engaging member 8, so that the engaging members are not easily broken, the middle notch portion is set to be laterally longer than the length of the engaging members as shown in fig. 1, and according to the cylindrical notch 6 extending laterally from the notch 6, the end face of the inserting end 3 of the notch 6 is set to be flush with the end face of the first engaging member 7, so that the elastic sheet 2 covered by the first engaging member 7 and the second engaging member 8 is of a solid structure, and the solidity of the engaging members can be increased.

Further, the thickness of the end face of the "U" shaped notch 6 is larger than that of the insertion end 3, increasing the thickness of the end face of the "U" shaped notch 6 can increase the solidity of the "U" shaped notch 6, and decreasing the thickness of the "U" shaped notch 6 on the side of the insertion end 3 can increase the elastic space of the spring 2.

Further, at least one step 11 is arranged on the fixed end surface of the elastic sheet 2 and the insertion end 3 along the direction of the free end 5, each step 11 is parallel to the fixed end surface, and as shown in fig. 1, a certain number of steps 11 are arranged to increase the elastic space of the elastic sheet 2.
