[0025] The touch panel 5 and the elastic support mechanism 6 are also included. The touch panel 5 is connected to the instrument body 4 through a data line. The elastic support mechanism 6 is arranged between the touch panel 5 and the instrument body 4. Under the support of the elastic support mechanism 6, the top surface of the touch panel 5 is closely attached to the lower surface of the explosion-proof glass 3. The touch panel 5 is provided with a functional touch key 51 for touch operation outside the explosion-proof glass 3. The elastic support mechanism 6 includes a telescopic rod 61 and a spring 62. One end of the telescopic rod 61 is fixedly arranged on the instrument body 4, and the other end is fixedly arranged on the touch panel 5. The spring 62 is arranged on the telescopic rod 61.
