[0019] The two ends of the button spring 2 are respectively connected with a deformation part 7, and the two deformation parts 7 extend into the through opening 3 respectively, and the two deformation parts 7 correspond to the two inner walls one by one, each deformation part 7 is placed on the support part 4 of the corresponding inner wall, and each deformation part 7 is connected with a clamping part 8 that is clamped with the clamping groove 6 of the corresponding inner wall. In the above scheme, by fixing the fixing seat 1 on the mobile phone circuit board 100, when installing the key spring piece 2, the clamping part 8 of the key spring piece 2 is placed in the through opening 3, the clamping part 8 will contact the extrusion inclined surface 5, and shrink inward under the action of the extrusion inclined surface 5 to cause the deformation part 7 to undergo elastic deformation, until the clamping part 8 corresponds to the card slot 6, the clamping part 8 will be clamped into the card slot 6 under the elastic force of the deformation part 7, thereby completing the installation operation of the key spring piece 2; when removing the key spring piece 2, force is applied to press the deformation part 7 so that the deformation part 7 drives the clamping part 8 to disengage from the card slot 6, and then the key spring piece 2 can be removed from the fixing seat 1, thereby completing the removal operation of the key spring piece 2.

[0020] Furthermore, the mobile phone circuit board 100 is provided with a positioning hole 101, and the bottom of the fixing seat 1 is provided with a positioning column 9 plugged into the positioning hole 101. By adopting the above scheme, the relative positions of the fixing seat 1 and the mobile phone circuit board 100 are positioned, and then the relative positions of the key spring 2 and the mobile phone circuit board 100 are positioned.
