Further, the receiving cavity is formed by at least two support plates 26 arranged at intervals and matched with the side wall profile of the mirror body 1. The setting of bearing plate 26 plays the bearing effect to the side wall of mirror body 1, avoids mirror body 1 level to rock, improves the installation stability of mirror body 1, fixes a position mirror body 1, makes things convenient for the dismouting. In addition, the wall thickness of the supporting plate 26 is 1.2mm, a certain deformation effect can be achieved, when the lens is installed, in the process that the lens moves downwards in the accommodating cavity, the supporting plate 26 is pressed by the side face of the lens to enable the supporting plate 26 to deform and spread until the clamping block 23 is clamped in the clamping groove 24, so that the side face of the lens and the large end where the clamping groove 24 is located are both stressed, and the installation stability of the lens is improved.
Further, the accommodating cavity comprises a first cavity 21 and a second cavity 22, the first cavity 21 is arranged at two ends of the frame body 2 and matched with the step-shaped notch 16, and the second cavity 22 is arranged in the middle of the frame body 2. The first accommodation cavity is provided with the mirror body 1 with the step-shaped notch 16, is positioned at two ends of the mirror body 1 fixing frame 2, and can be used for observing light rays emitted by the mirror body 1 from two sides of the mirror body 1 fixing frame 2, so that the illumination range of 180 degrees is reached, and the warning effect is good.
The frame body 2 is made of ABS material, has strong elastic deformation capability, and the bearing plate 26, the clamping block 23 and the mirror body 1 fixing frame 2 are integrally formed and manufactured, so that the manufacturing is convenient and the cost is low.
