DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to an optical machine of a projection system, and more particularly to an improvement of a lens fixing device for an optical machine. [Prior Art] In the optical machine used in the projection system, 'it usually includes a lower case, and various lens elements are miscellaneous in the lower case during the initial assembly process in the initial stage of manufacture, and then the initial cover is applied after the initial adjustment. Hehe. The optical path system of a optomechanical machine usually consists of a plurality of lens elements. In order to achieve a better projection effect, it is often necessary to adjust the illuminance or distance of each lens element of the optical machine to form a suitable optical path. Each of the lens elements of the optomechanical machine typically employs a sheet of lens on a mirror mount device to "change the angle of the lens and the distance between each other" by adjusting the lens holder to form a suitable optical path system. As shown in the first figure, the conventional lens mosquito device includes a fixing frame lm, and the sheet lens holding device 102 is vertically mounted on the top end of the fixing frame 1〇1 by screws, and the front end of the lens holding device 102 The elastically deformable clamping groove 1〇3 is formed, and the top end of the lens 1〇4 is clamped in the missing holding groove, and the bottom end of the lens abuts against the base 1〇5 of the fixing frame 101. However, in the lens device, the lens is held only by the clamping device 1〇2 at the top end, and the clamping device is fixed to the fixing frame 101 by screws, so that the lens is not firmly clamped and easily falls off. And the lens positioning accuracy is poor. SUMMARY OF THE INVENTION An object of the present invention is to provide a optomechanical lens fixing device with high clamping reliability. Another object of the present invention is to provide an optical machine having an improved lens securing device which has high lens clamping reliability. 5 200819811 For the purpose of reaching the cylinder, the lens of the hair supply-county machine is fixed. The lens fixing device includes a frame-shaped zone, and the middle part of the miscellaneous (four) position is perpendicular to the fixed zone_pressure part. Two elastic clamping portions are formed on both sides of the connecting portion connecting the pressing portion and the fixing portion, so that a lens can be lost and attached to the fixing region. The invention also provides a seeding machine comprising a body of the optical machine and a lens disposed in the body of the optical machine, the lens being fixed by a lens fixing device. The lens fixing device comprises a frame-shaped fixing region, and a pressing portion perpendicular to the fixing portion is disposed at a middle portion of the top edge of the frame-shaped fixing portion to extend two elastic clamping portions on both sides of the connecting portion between the waste portion and the fixing portion胄, it can be used to hold the lens while it is attached and fixed to the fixed area. Compared with the prior art, the optomechanical lens fixing device of the present invention has a clamping elastic piece on the top and a fixed structure of the body, and can set the lens age@ on the fixed area, so only the pressing of the lens is required. Move the top of the pressing part, after the installation of the loose part, the clamping piece automatically recovers the lens, the lens scale is highly reliable, and the positioning is accurate. In addition, the opening of the base can facilitate the adjustment of the lens, and the operation is simple and convenient. [Embodiment] The main improvement of the present invention is the fixing device of the lens 5 of the optical machine used in the projection system. The other structure of the optical machine is substantially the same as that of the conventional optical machine. Therefore, the other structures of the optical machine are not described in detail. Let me explain it first.凊 Referring to the second embodiment of the invention, the optical machine of the present invention comprises a light machine body composed of an upper cover 1 and a lower case 2, and the lens 5 is mounted on the lower part of the optical machine body by the lens fixing device 3 Inside. Referring to the third figure and in conjunction with the fourth figure, the lens fixing device 3 includes a hollow four 200819811 box. The positioning area 3 extends upward from the middle of the top edge 32 of the fixing area 31 to form a connecting portion 33. The sheet-like dust-receiving portion 34 extends from the connecting portion 33 and is approximately vertical. A clamping spring 35 is formed to extend from the two sides of the connecting portion. The holding elastic piece 35 includes a v-shaped elastic portion 351 connected to the connecting portion % and an l-shaped holding portion connected to the elastic portion 351. The v-shaped elastic portion is protruded rearwardly and the holding portion 352 extends to the front side surface of the fixed area m plane. The gripping portion 352 can hold the top edge of the lens 5 together with the surface of the fixing portion 31. The connecting portion 3-7 is formed by projecting from the middle of the left and right side edges 36 of the fixing portion 31 to the two sides, and extends outward from the connecting portion 37 to form an elongated blocking portion %. The tip end portion of the blocking portion is slightly bent forward, at an angle to the plane of the fixing portion 31, so as to prevent the bottom end of the left and right sliding portion of the lens 5 from being bent toward the fixing portion 31 to form the buckle portion 38. It is buckled between the buckle portion and the zone 31. In the middle of the bottom edge 39 of the fixing portion 31, it extends forward in the direction opposite to the vertical fixing portion to form a base 40, and the base 4 has two opposite semicircular openings formed therebetween. On the left and right sides of the base 仞, the bottom edges 39 of the self-determining zone 31 extend in a direction perpendicular to the plane of the comparative zone 31 to form two support legs 41 for further positioning of the lens 5. As shown in the fourth figure, when the lens 5 is assembled, the bottom edge of the lens 5 is first inserted into the space formed between the bottom edge 39 of the humanoid region and the buckle portion 381 of the side stopper portion 38, and The bottom edge of the lens $ abuts against the base 40 and the support leg 41. Pressing the reduction portion % on the top edge of the fixing portion 31 can drive the clamping elastic piece 35 of the top edge to open the clamping portion 352 of the clamping elastic piece 35 and the lens fixing area - the larger limb, the cake The top edge of the age of 5 will be set to 31. After the section 34, the unloaded elastic piece 35 is elastically restored to cause the clamping portion to loosen the top edge of the lens 5 to hold the joint. 7 200819811 Between the fixed portion 31 and the holding elastic piece 35. The bent top end of the left and right side stop portions can block the left and right sides of the lens 5, thereby preventing the lens 5 from sliding left and right. After the lens fixing device 3 is installed in the optical machine body, the base 4 has a semicircular opening
