By screwing the focusing screw 41, the display bracket 32 and the display 31 can be driven to move up and down, so as to adjust the focal length.

[0027] There are two sets of lens modules 2, which are respectively arranged at the lower sides of both ends of the lens frame 1 and correspond to the receiving grooves.

[0028] The lens module 2 includes a lens bracket 21, a first optical lens 22, a second optical lens 23 and a third optical lens 24. The lens bracket 21 is a frame structure with a thick upper end and a thin lower end, and the upper end, the front end and the rear end are all open structures. The upper end of the lens bracket 21 is connected to the lens frame 1. The first optical lens 22 is supported on the display bracket 32 and is located below the display 31.
