Referring to fig. 3, in a specific implementation manner, the lens 213 and the tubular push rod 21 may be integrally formed, so as to reduce the assembly difficulty, and prevent a gap between the lens 213 and the tubular push rod 21 from causing water leakage and damage to the light source 11 connected to the support 1.
In a specific implementation manner, the lens 213 may be a Fresnel lens structure, so that the point light of the light source 11 can be refracted to form parallel light parallel to the axis of the tubular push rod 21 and then emitted from the light guide portion 31 of the operation structure 3, so that the light loss of the light source 11 is less, the light transmittance is better, the light emission is more uniform, and the light emission effect of the emergency stop button is better.
The operation structure 3 includes a light guide portion 31, and the operation structure 3 is used for an operator to perform an operation of the emergency stop button, such as pressing, pulling or rotating operation.
