[0028] The optical lens 164 is a transparent glass. Preferably, the optical lens is made of ΒΚ7 optical glass. The optical lens 164 is fixed to the concave surface 1616 of the recess 1614 by the colloid layer 162. [0029] In the embodiment, the pressing member 165 includes two pressing pieces 1651. The second pressure 096142420 table 箪 珑Α 0101 page 10 / total 20 pages 0993370103-0 1337293 October 14th, 999, the nuclear replacement page splicing piece 1651 corresponding to the second connecting hole 1618 on the holding member 161 is provided with a third Connection hole 1 652. The third connecting hole 1 652 of the holding member 165 cooperates with the first connecting hole 161 3 of the holding member 161 and holds the holding member 161 and the pressing member 165 by the bolt 166. together. At the same time, the pressing piece 1651 is pressed against the edge position of the optical lens 164. In practical applications, the number of the pressing pieces 1651 may be one or more, which are respectively pressed to the edge positions of the optical lens 164. [0030] In practical applications, the holding member 161 and the receiving frame 179 may be fixed together by gluing or binding; the vibrating member 163 may also be fixed by gluing or tying. The number of the vibrating members 163 may be one or more than one of the frames 1611 of the holding member 161. The automatic dust removing device 16 may not be provided with the pressing member 165, and is not limited to the embodiment. [0031] The projector is provided with an automatic dust removing device, and the vibration component in the automatic dust removing device can work before the projection lens of the projector is projected, and the vibration is shaken off and the optical lens for protecting the liquid crystal film is adsorbed and adsorbed in the automatic dust removing device. Air dust on it. In this way, it is possible to avoid staining problems when the projector is projected. [0032] In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
