The guide rail 21 is axially slidably coupled to the guide rail 21, and the boss 311 is radially and interference-coupled with the guide rail 21.

The combined button structure provided by this embodiment is different from the ordinary button. The elastic arm 31 of the button 20 is not on the body of the button 20 but on the lamp mirror 30. The elastic arm 31 is provided with a boss 311, and the position corresponding to the boss 311 on the button 20 The guide rail 21 is disposed to axially slide the boss 311 in the guide rail 21 to ensure the elasticity of the elastic arm 31, and also prevent the button 20 from being inside the lamp mirror 30. Do the axial rotation. The radial direction of the boss is interference-fitted with the guide rail 21 on the button 20, so that the elastic arm 31 has a certain amount of preload, preventing the button 20 from shaking abnormal noise, and simultaneously utilizing the elastic arm 31. The resilience of the button ensures the reset state of the button 20.
