In this embodiment, as shown in fig. 1, two flanges 32 are disposed in parallel, and a gap is formed between the two flanges 32, where the gap is used to provide a moving space for tightening and expanding the anchor ear 3. The two wing plates 32 are respectively provided with a first through hole 321 and a first threaded hole, threads are arranged on the inner side of the first threaded hole, and the first fastener 7 penetrates through the first through hole 321 and then is in threaded connection with the first threaded hole and is connected with the two wing plates 32. By adjusting the position of the first fastening piece 7 and adjusting the distance between the two wing plates 32, the hoop 3 is tightened and expanded, so that the first bulge 41 and the first connecting portion 22 are in close contact with the lens 1, the tightness of the lens module 10 is ensured, and the position of the lens 1 is adjusted.

In some embodiments, as shown in fig. 1 and 4, the first fastener 7 comprises a bolt; the first accommodating groove 42 comprises an accommodating groove body and an avoidance groove body, the accommodating groove body accommodates the hoop plate 31, the avoidance groove body accommodates the two wing plates 32 and the first fastening piece 7, a second through hole 421 is formed in the side wall of the avoidance groove body along the axis direction of the first fastening piece 7, and the second through hole 421 is used for exposing the head of the bolt.

In this embodiment, as shown in fig. 1 and fig. 4, the second through hole 421 is formed in the side wall of the avoidance groove body, and the second through hole 421 is used for exposing the head of the bolt, so that the hoop 3 can be loosened under the condition that the first sealing element 4 is not detached, the lens 1 is adjusted, and the sealing can be realized through the first sealing element 4 when the lens 1 is adjusted, so that the sealing performance of the lens module 10 is ensured. Specifically, in the use process of the camera, if the lens 1 needs to be adjusted, only the second fastening piece 531 needs to be removed, the sealing cover 5 is lifted, and the screwdriver penetrates through the second through hole 421 on the side wall of the avoidance groove body to loosen the first fastening piece 7, so that the anchor ear 3 is expanded, and the position of the lens 1 is adjusted. In this process, the sealing structure formed by the sealing cover 5 and the side wall of the lens 1 and the upper surface of the first main body portion 21 fails, but the sealing structure formed among the first sealing member 4, the front cover 2 and the lens 1 can still seal the joint between the lens 1 and the front cover 2, so that the tightness of the camera lens module 10 in the process of adjusting the lens 1 can be effectively ensured.

In some embodiments, as shown in fig. 1 and 3, the first body 21 is provided with a positioning post 211, and the orthographic projection of the positioning post 211 is located between the orthographic projections of the two wings 32 along the direction perpendicular to the first body 21.

In this embodiment, as shown in fig. 1 and 3, the positioning column 211 can position the anchor ear 3, so as to install the anchor ear 3. And the positioning column 211 is arranged between the two wing plates 32, so that the tightening degree of protection can be limited, the probability of the hoop 3 collapsing due to the overlarge tightening degree and the probability of breakage of the surfaces of the first connecting part 22 and the lens 1 due to overlarge extrusion force generated when the hoop 3 is tightened are reduced, and the structures such as the first connecting part 22 and the lens 1 are adversely affected.
