As Figure 1-5, this utility model embodiment provides a kind of adjustable projector of projection angle, bag
Including projector main body 1, the front end of described projector main body 1 is provided with projection lens 2, described projection lens
2 are provided with projection angle regulating device 3, and described projection angle regulating device 3 is installed by buckle structure
In described projection lens 2 front end, described projection angle regulating device 3 includes a housing main body 31, institute
Stating housing main body 31 two ends and be equipped with light hole, described housing main body 31 is internal to be provided with for regulating throwing
First optics 32 of shadow angle, described first optics is additionally provided with the first adjusting knob 41,
Described first optics 32 is arranged in the exit direction of projection ray, described first optics 32
For plane mirror or corner cube prism.
It is preferred that described housing main body 31 is internal is additionally provided with the second optics device for regulating projection angle
Part 33, described second optics 33 is additionally provided with the second adjusting knob 42, described second optics device
Part 33 is plane mirror or corner cube prism.
The adjustable projection of a kind of projection angle this utility model provided below in conjunction with specific embodiment
How instrument carries out the regulation of projection angle is further detailed: in the present embodiment, described shell
Main body 31 is respectively arranged at two ends with the first light hole and the second light hole, and the first light hole passes through buckle structure
Being arranged on described projection lens 2 front end, the light that projection lens is sent by the second light hole is flat through first
Face reflecting mirror 32 or the second plane mirror 33 project on perspective plane after regulating projection angle；Please
With reference to Fig. 1-2, the projection lens 2 of the adjustable projector of this projection angle is provided with the first plane mirror
32, the light that projector straight line projects can be reflected by the first plane mirror 32, changes light
The transmission direction of line, thus adjust the position of the projected picture of projector；Refer to Fig. 3-4, it is preferable that
