First, through the action of the surrounding frame 3, the surrounding frame 3 and the baffle 4, the connection holes 2 and the display part on the front of the detection device body 1 are provided with a preliminary dustproof effect, and then the electric push rods 8 on the two horizontal plates 7 are started. Since the connection plates 10 installed on both sides of the T-shaped plug plate 9 are installed at the output ends of the two electric push rods 8, and the T-shaped plug plate 9 is movably inserted in the strip groove 6, the T-shaped plug plate 9 is slowly moved upward, wherein the T-shaped plug plate 9 will not move out of the strip groove 6, and the plurality of connection holes 2 on the detection device are exposed, so that the measuring device is correctly connected to the connection hole 2 and the voltage is measured. When it is not needed, the two electric push rods 8 are started again, so that they drive the T-shaped plug plate 9 to be completely inserted in the strip groove 6, thereby preventing external dust from being adsorbed on the plurality of connection holes 2, thereby improving the accuracy of the voltage detection of the device when the device is used next time, thereby improving the use effect of the voltage detection device.

[0026] Embodiment 2, as Figure 2-Figure 4 As shown, two connecting plates 10 are fixedly installed on the outer wall of the T-shaped plug plate 9, and the output ends of the two electric push rods 8 are fixedly connected to the bottoms of the two connecting plates 10, an observation port 11 is opened on one side of the outer wall of the baffle 4, and a visual window 12 is fixedly installed on the inner wall of the observation port 11, two plug blocks 13 are fixedly installed on the outer wall of the baffle 4, and two concave blocks 14 are fixedly installed on the outer wall of the frame 3, and the outer walls of the two plug blocks 13 are movably inserted into the inside of the two concave blocks 14, the inner walls of the two plug blocks 13 are threadedly connected with bolts 15, and the outer walls of the two bolts 15 are movably inserted into the inside of the two concave blocks 14.
