A rotating shaft 8 is fixedly installed on the back of the spring body 1. A connecting rope 9 is wound around the front surface of the rotating shaft 8. A fixing plate 7 is fixedly installed on one side of the connecting rope 9. A support plate 6 is fixedly installed on one side of the fixing plate 7. Teeth 4 are fixedly installed on one side of the support plate 6. A limit groove 10 is opened on the top of the support plate 6. Limit blocks 5 are fixedly installed on all four sides of the top of the spring body 1.

[0020] This technical solution addresses the complex and ever-changing environments faced by mobile communication devices during actual use. Vibrations and drops during daily use, or operation of the device in varying temperature and humidity environments, all affect the stability of the contact spring. Existing contact spring designs have numerous shortcomings, resulting in unsatisfactory limiting effects. Example 2:

[0021] Based on Embodiment 1, this utility model is as follows: Figure 3 and Figure 4 As shown, the front surface of the spring body 1 is provided with three snap-fit ​​holes 2.
