Specifically, the limiting portion 311 and the lever portion 312 are integrally formed, and both the limiting portion 311 and the lever portion 312 are cylindrical. The limiting portion 311 is cylindrical, which facilitates the rotation of the limiting portion 311. The lever portion 312 is cylindrical, which can prevent the sharp edges on the lever portion 312 from causing damage to the user's hand.

[0045] In this embodiment, the lever portion 312 is located at one end of the limiting portion 311 close to the elastic member 32, and the distance between the lever portion 312 and the L-shaped groove 111 is greater than or equal to the distance between the top of the limiting portion 311 and the bottom of the installation slide groove 40 when in the locked position. Specifically, the distance between the lever portion 312 and the L-shaped groove 111 is greater than or equal to the distance between the top of the limiting portion 311 and the bottom of the installation slide groove 40 when in the locked position, so as to ensure that when the lever portion 312 moves down from the locked position to the bottom of the L-shaped groove 111, the limiting portion 311 will not extend out of the installation slide groove 40 to interfere with the removal or installation of the sliding switch plate 20.
