The structural strength between 21B1 further increases the elastic restoring force of the elastic structure 21B under pressure to ensure that the elastic structure 21B can press the main body 210 to the back plate 11, so that the back plate 11 can surely cover the main body 210. The opening 21F is abutted and the receiving groove 215 is sealed. It is worth mentioning that the base 21 may further comprise a skirt structure 21C extending around the surrounding wall 211, and the skirt structure 21C and the elastic structure 21B are located on opposite sides of the body 210. When the elastic structure 21B presses the main body 210 against the back plate 11, the petticoat structure 21C can be superposed on the area around the light-transmitting opening 110 of the back plate 11 to further block the ambient light from entering the receiving groove from the abutting opening 21F. The shed structure 21C can be used to seal the light-transmissive opening 110 and the light-sensing module 20 in the accommodating groove 215.

In addition, an abutting protrusion 21B4 may be formed on the abutting wing portion 21B1 of the elastic structure 21B, which may be used to abut the carrier 12. When the carrier 12 and the sensing device 2 are mounted on the backboard 11, the abutting protrusion 21B4 can increase the pressing stroke of the carrier 12 against the abutting wing 21B1 to ensure that the elastic arm portion 21B0 can generate sufficient deformation. The main body 210 is pressed down on the backboard 11.
