Preferably, the first color is green, and the second color is red. The color of the color block 4 may also be other colors. One end of the elastic band 3 is connected to the color block 4 to apply a downward pulling force to the color block 4; one end of the rebound band 2 is connected to the color block 4 to apply an upward pulling force to the color block 4. In another embodiment, the rebound band 2 can apply a downward pulling force to the color block 4, and the elastic band 3 applies an upward pulling force to the color block 4. The structure can be changed according to actual conditions.

[0034] The mounting housing 1 is provided with a display window, and the color of the color block 4 can be observed through the display window. When the elastic band 3 is not damaged, the elastic band 3 and the rebound band 2 apply tension to the color block 4 from the upper and lower directions respectively, and the first color of the color block 4 is observed through the display window; when the elastic band 3 is damaged, the color block 4 moves under the pull of the rebound band 2, and the second color of the color block 4 is observed through the display window.
