Description of the invention [Technical field to which the invention belongs] The present invention relates to a physical projector, particularly to a physical projector with a fine-tunable lens module. [Prior art] The most common presentation auxiliary equipment known to be used is a projector for using a slide. With the advancement of technology, the available presentation aids now include coffee projectors, notebook computers, and physical projectors. The physical projector ′ can display the object on the projection screen without making the target object (such as a document or object) to be presented into an electronic image file or document file. The physical projector will directly display the captured image on the projection screen by placing the subject of the presentation: placed in the range of the digital lens. As a result, physical projectors can reduce the time required for briefing staff to prepare presentation materials. Most of the lens modules of conventional physical projectors cannot be used to fine-tune the level. If the physical projector is placed on an uneven table top, the image projected by the physical projector often appears blurred. Therefore, in order to project in kind and project a high-quality image, an innovative and adjustable lens module is necessary. 1235877 [Summary of the Invention] The purpose of the present invention is to provide a physical projector with a fine-tunable lens module to improve the quality of the projected image. According to the above object of the present invention, a through-object projector having a fine-tunable lens module is proposed. This physical projector unit includes a stand with a telescopic function, which is fixed to the side of the base. The cantilever adjustment module is connected via the first shaft and telescopic bracket. The cantilever adjustment module includes a cantilever, a first rotating shaft, and a knob with a thread, and the cantilever f leans to the first turn; there is a hole at the place. The lens module is fixed on the cantilever. The above-mentioned threaded knob can be screwed into the screw hole on the cantilever, and one end of the cantilever can be moved up and down by rotating the knob, so that the knob controls the lens module with the second rotation axis as a fulcrum. From the above, it can be known that applying a physical projector with a fine-tunable lens module of the present invention can project a high-quality image. The present invention provides a lens module with an adjustment function of up to three degrees of freedom through a retractable bracket, a rotating shaft, and a fine adjustment mechanism, so that the lens module can capture high-quality images very quickly. [Embodiment] In order to project a high-quality image from a physical projector, the present invention provides a physical projector with a fine-tunable lens module. The fine-tuning mechanism on the cantilever and the detection of the spirit level enable the lens module to be held in a horizontal position to capture high-quality images. Referring to FIG. 1, a schematic diagram of a 1235877 physical projector according to a preferred embodiment of the present invention is shown. The physical projector 20 of the present invention has a lens module 22 for capturing a projected object (not-drawn image) placed on the base 34, and then passing this image through a liquid crystal projector (not shown) ) Projected on the screen. = Any shortcomings in image capture will be reflected in the projected image. In this embodiment, the lens module 22 is fixed on a cantilever adjustment module 23, and the lens group 22 is added to A leveler 24 is installed to detect the adjusted level of the lens module η. The cantilever adjustment module 23 is connected to the upper bracket 30 through the rotation shaft 28. The lens module 22) is rotated by the rotation shaft 28 and the cantilever adjustment module 23. Adjust the level level and check the adjustment result with the spirit level 24. The dog exit of the upper bracket 30 is inserted into the hollow cavity of the lower bracket, making it a retractable bracket. The lower bracket 32 is fixed to the side of the base 34. January / ",, Figure 2, It is a schematic diagram of a lens module of an object projector according to a preferred embodiment of the present invention. The cantilever adjustment module 23 may be another one: the cantilever 26 and the fine adjustment mechanism 33. The cantilever 26 has a screw hole 35 for screwing the threaded part of the button 25 and is connected to the fine adjustment mechanism 33 by a rotating shaft 31. The fine adjustment mechanism 33 uses the rotating shaft 31 as a fulcrum and rotates the knob U to reach the position of the & cantilever 26. The fine adjustment of the level 4 of the lens module 22 is further advanced. The person turned the beta button with a flathead screwdriver. However, the present invention does not limit the shape or use of the knob 25: it can be turned in various ways. A level meter 24 is also designed on the lens module 22, which can be used to detect whether it is level after adjustment. ^ As can be seen from the description of the preferred embodiment of the present invention, a physical projector with a U_ group can be used to project a high-quality image. The present invention can provide a lens module with an adjustment function of 1235877 and three degrees of freedom through a bracket, a rotating shaft and a fine-tuning mechanism from μ + β, so that the lens module can capture high-quality images very quickly. Although, ',,', this description has been disclosed as a preferred embodiment, but it is not intended to limit the present invention. Anyone skilled in this art will not depart from the essence of the present invention. 'Equipments can be modified and retouched. Therefore, the scope of protection of the present invention shall be determined by the scope of patents attached to the attached towel.
