The base includes: a horizontal plate 1 and a vertical plate 2. The vertical plate 2 is arranged at the top of the horizontal plate 1 and is fixedly connected to the horizontal plate 1. A first threaded hole is provided at the top of the vertical plate 2. A recess is provided on one side of the horizontal plate 1. The first thread is connected to the recess. The recess is used to load the electric switch 6. The meter bracket 5 is arranged at the top of the horizontal plate 1 and is connected to the top of the horizontal plate 1. A second threaded hole is provided on the meter bracket 5. The first threaded hole and the second threaded hole are opposite to each other, and the central axes coincide. The adjusting screw 3 is arranged at the top of the meter bracket 5, and is used to compress the electric switch 6 to switch the state of the electric switch 6. The adjusting screw 3 can penetrate the first threaded hole and the second threaded hole to compress the switching button 9 on the electric switch 6 to achieve the state switching of the electric switch 6.

[0040] In some specific embodiments, a center line of the first threaded hole coincides with a center line of the second threaded hole.

[0041] In some specific embodiments, the adjusting screw is provided with a thread 4. Here, the thread 4 matches the center line of the first threaded hole and the second threaded hole. The top of the adjusting screw 3 is also provided with a knurling to facilitate the rotation of the adjusting screw 3.

[0042] In some specific embodiments, a fixing pin 10 is further included. The fixing pin 10 is arranged in the notch and fixedly connected to the horizontal plate 1. Two fixing pins 10 are provided. It should be noted that one end of the fixing pin 10 is fixedly arranged on the inner wall of the notch of the horizontal plate 1.

[0043] In some specific embodiments, the axis of the fixing pin 10 is perpendicular to the axis of the transverse plate 1 .
