Ensure the coaxiality and concentricity of the lens module. However, this method is only applicable to the fixed lens group (ie, the fixed focus module). If there is a movable lens group in the lens module, during the use of the lens module, the zoom of the lens module will be realized by the movement of the movable lens group. After the movable lens group is moved, there are eccentricity problems between multiple movable lens groups and between the movable lens group and the fixed lens group (that is, the coaxiality and concentricity are reduced), so how to solve the movable lens group and the fixed lens group, Or the eccentricity problem between the movable lens group and the movable lens group is a technical problem currently faced.

In other words, the lens module mainly includes a lens barrel 1 , a lens group 2 and an adjustment member 3 . The lens barrel 1 is used to carry the lens group 2 . On the one hand, the adjusting member 3 plays the role of connecting the lens barrel 1 and the lens group 2, and on the other hand, is used to adjust the eccentricity of the lens group 2 to ensure the coaxiality and concentricity of the lens module.

Specifically, the lens barrel 1 has an accommodating space and a cylindrical body enclosing the accommodating space. The lens group 2 is arranged in the accommodating space. The installation groove 10 is opened in the cylindrical body, and the installation groove 10 penetrates the outer wall and the inner wall of the cylindrical body.

In a specific implementation, when it is necessary to adjust the eccentricity of a lens group 2 in the lens module, a set of installation grooves 10 are opened on the lens barrel 1, wherein the installation position of the installation groove 10 is the same as the installation position of the lens group 2. Correspondingly; when the eccentricity of multiple lens groups 2 in the lens module needs to be adjusted, multiple sets of installation grooves 10 are opened on the lens barrel 1 , wherein the installation grooves 10 are respectively set corresponding to the lens groups 2 one by one.

The lens group 2 includes at least one lens 22 and a fixing frame 21 , wherein the lens 22 is fixed on the fixing frame 21 .
