Description of the Invention: [Technical Field] The present invention relates to a projector, and more particularly to a projector having a support mechanism. [Prior Art] With the advancement of society and the development of electronic technology, projectors have become indispensable auxiliary equipment for people's life, work, and study, such as offices, classrooms, conference rooms, home theaters, and so on. The projector is for displaying an image represented by the input image signal on the projected screen in an enlarged manner. Generally, when using the projector, it is necessary to adjust the projection angle of the projector first. The industry usually sets 70% by rotating the screw at the bottom of the projector. That is, when the angle of the projector needs to be adjusted, the generator is raised, then the height of the screw is adjusted, and then the projector is lowered. =: Is the angle correct? If it is not suitable, the projector should be lifted again. ◎ 2 Newly adjust the 'repeated' to the appropriate angle until the adjustment is made at the angle of the projection camera, which not only makes it difficult to adjust to a suitable projection angle. The method of setting the screw at the bottom of the instrument is cumbersome for the adjustment of the projection, and the user, thereby affecting the display effect of the projected image. [Inventive content] There is a need for a projector that is convenient for the user to adjust the projection angle 200928560. . The apparatus includes a fuselage and a support mechanism for supporting the fuselage. The branch mechanism includes a bracket that can be rotated (4) mounted on the fuselage, and a fixing member that is fixed at different positions on the guide member to adjust the angle of the fuselage. When adjusting the projection angle of the projector, it is only necessary to apply a force to one end of the fuselage to lock the bracket to the guide member when the body is deflected to the required projection angle, that is, by fixing the bracket at Different positions on the guides enable angular adjustment of the projector. Therefore, it is more convenient for the user to adjust the projection angle. [Embodiment] As shown in Figs. 1 and 2, a perspective view of a projector 1〇〇 and an exploded view of a projector 1〇〇 are shown in a preferred embodiment. The projector 1 includes a body and two mechanisms 20 symmetrically disposed on opposite sides of the body 10 for supporting the body 1 . The body 10 has a substantially rectangular parallelepiped shape with a lens 13 at its front end, and light inside the body 1 can be projected through the lens 13. The body 1 includes a first side s u and a second side & 12 on both sides of the lens 13, wherein the first side 11 is opposite the second side 12. Screw holes 15 are formed in each of the first side u and the second side. The two supporting mechanisms 20 include a rotating shaft 2 disposed on the body 1 , a bracket 23 rotatably mounted on the rotating shaft 21 , a guiding member 25 fixed to the body 10 , and a fixing member for fixing the bracket 23 to the guiding member Fixing member 27 on 25. 200928560 The two rotating shafts 21 can be separate components that are fixed to one of the fuselage or the support frame 23 and rotatably mounted to the other of the fuselage 1 or the bracket 23; On one of the body cymbal or the bracket, it is rotatably fitted to the other of the body 10 or the bracket 23. In the present embodiment, the two rotating shafts 21 respectively protrude from the central portion of the first side 11 and the second side 丨2 of the body 1 , which are integrally formed with the body 1 . The guide member 25 may be integrally formed with the body 10 or may be a separate member. In the present embodiment, the guide member 25 is a separate component. A guiding groove 251 ′ is formed in the guiding member 25, and the guiding groove 251 has an arc shape. A positioning hole 253 is defined in the guiding member h. The guide member 25 further includes a screw 255 which is threaded through the positioning hole 253 and screwed into the screw hole 15 of the body 1b to fix the guide member 25 to the body. The bracket 23 is sleeved on the rotating shaft 21 for supporting the body 10 such that at least one end of the body 10 is suspended. The bracket 23 can be an integrally formed component or composed of a plurality of components. In the present embodiment, the bracket 23 is composed of a plurality of components, and the bracket 23 includes a first leg 23a and a second leg 23b, and the first leg 23a and the second leg 23b are symmetrically disposed. The first leg 23a and the second leg 23b respectively include mounting ends 231a and 231b rotatably sleeved on the rotating shaft 21, and supporting ends 233& and 233b for contacting the table top or other objects. Each of the fitting ends 231a and 231b defines a through hole 235a and 235b through which the rotary shaft 21 can pass. The fitting ends 23la and 23ib are also convexly provided with stoppers 237a and 237b. When the second leg 23b is rotated to a predetermined angle with respect to the first leg 23a, the stopper portion 237a and the stopper portion 23 are in phase 8. 200928560 'Resist, thereby preventing the second leg 23b from continuing to move relative to the first leg 23a. A fixing hole 239b is further defined in the second leg 23b, and the fixing hole 239b is located opposite to the guiding groove 251 on the guiding member 25. When assembling: firstly, the positioning hole 253 of the guiding member 25 is opposed to the screw hole 15 of the body 1 ' 'move the screw 255 through the positioning hole 253 and screw into the screw hole 15' to fix the guiding member 25 at Second, the second leg 23b and the first leg 23a are sequentially sleeved on the rotating shaft 21, and the second leg 23b and the first leg 23a and the first leg 23a and the first leg The two leg legs 23b and the rotating shaft 21 are relatively rotatable; finally, the fixing member 27 is placed in the fixing hole 239b. As shown in FIG. 3, the second leg 23b is rotated. When the second leg 2 is rotated to a predetermined angle, the stopping portion 237a and the stopping portion 237b are in contact with each other, and the second leg 23b stops rotating. The body 1 is supported by the support mechanism 2〇 and placed again. Then, a force is applied to one end of the body 1 , so that the body 10 is provided with one end of the lens 13 tilted or lowered, so that the projection angle of the camera 100 can be adjusted, when adjusted to a desired angle, A force is applied to the fixing = 27, and the fixing member 27 is passed through the second leg 2 and then fixed in the guide groove 251. Thus, the adjustment of the projection angle of the projector 100 is completed. Because, in adjusting the projection angle of the projector 100 = the end applied - the force, the W to the factory X, 'the second branch 23b is locked in the guide groove of the guide 25 ' _ ' The second leg 23b 0 is positioned at a different position in the guide groove 251 to achieve an angular adjustment of the projector. $以,投影 9 200928560 ' The instrument 100 is more convenient for the user to adjust its projection angle.
