[0046] Furthermore, the spring component 1 is configured as a straight spring; the aperture of the through hole 211 is greater than or equal to the outer diameter of the spring component 1; one end of the spring component 1 passes through both ends of the through hole 211 in sequence to be connected to the riveted component 21; the locking portion 212 is located in the middle of the riveted component 21, and one end of the riveted ejector pin 521 can be adapted to be inserted into the middle of the spring component 1 to abut against the outer side wall of the locking portion 212; after the riveted ejector pin 521 cooperates with the riveted base 511 to clamp the locking portion 212, the two ends of the spring component 1 and the locking portion 212 are connected at the same time, making the connection between the spring component 1 and the stamping sheet 2 more secure and preventing the two from shaking or shifting relative to each other.

[0047] Furthermore, the size of the end of the riveting pin 521 away from the working position 33 is increased to form a pressing auxiliary portion 522; when the riveting pin 521 clamps the locking portion 212, the pressing auxiliary portion 522 abuts against the spring member 1 to elastically contract the spring member 1. The elastic contraction of the spring member 1 can be used to assist the riveting pin 521 in clamping the locking portion 212, so that the deformation shape of the locking portion 212 is flatter.

[0048] Furthermore, the fixing position 512 is configured as a limiting groove recessed in the outer wall of the riveted base 511; the inner wall of the limiting groove can be close to the outer wall of the stamping sheet 2 to limit the stamping sheet 2, so that the stamping sheet 2 is not easily displaced or detached and falls off, and facilitates the angle fixing of the riveted component 21 to connect with the spring component 1.

[0049] The rest of this embodiment is the same as that of the first embodiment. The features not explained in this embodiment are all based on the explanations of the first embodiment and will not be described in detail here.
