Next, the deformed shaft portion of the rotating shaft 282 of the pivoting mechanism 28 sequentially passes through the spacer 284, the friction plate 286, the through hole 2880 of the rotating bracket 288, the through hole 2902 of the active spacer 290, and the follower pad 292. The hole, the pivot hole of the base portion 2942 of the connecting frame 294 and the elastic piece 296, and then the nut 298 is locked to the end of the rotating shaft 282. The tabs 2862 of the friction plate 286 and the tabs of the active spacer 290 are respectively inserted into the latching holes 2884 of the rotating bracket 288, and the tabs 2924 of the follower pad 292 are inserted into the buckles of the base 2942 of the connecting frame 294. In the hole. The spacer 284, the follower pad 292, the connecting frame 294 and the elastic piece 296 are non-rotatable with respect to the rotating shaft 282, and the friction plate 286, the rotating bracket 288, and the active spacer 290 are rotatable relative to the rotating shaft 282. Then, the limiting member 2882 is screwed onto the rotating bracket 288, and the smooth surface of the end portion of the limiting member 2882 is abutted against the circular arc surface 2946 of the base portion 2942 of the connecting frame 294, so that the rotation angle of the connecting frame 294 can be defined. Then, the rotating bracket 288 is fixedly coupled to the display screen 10 of the liquid crystal display device 100. This completes the assembly of the pivoting mechanism 28. Then, the deformed shaft portion of the rotating shaft 302 of the pitching mechanism 30 sequentially passes through the pivoting hole of the pivoting portion 2944 of the connecting frame 2010, the fitting hole 3046 of the fitting 304, and the other pivoting of the connecting frame 294. The pivoting hole of the portion 2944 is then engaged with the snap ring 3026 of the rotating shaft 302. The connecting portion 3042 of the fitting 304 is fixedly coupled to the bracket 242, thereby completing the assembly of the pitching mechanism '30. Finally, the first, second, and third sets of shells 244, 246, and 248 are respectively fitted over the holder 242, and the liquid crystal display device 100 is assembled. Referring to Fig. 2 together, the axes a, b, and c shown in Fig. 2 refer to the axis of rotation 264 of the rotating mechanism 26, the axis of rotation 282 of the pivoting mechanism 28, and the axis of the axis of rotation 302 of the pitching mechanism 30, respectively. In use, the display screen 10 is rotated to rotate the bracket 242 about the axis a. One end of the bracket 242 is gradually away from the base 22, and the torsion spring 276 is also rotated to release the preset torque, thereby reducing the pulling force until the bracket 242 The abutting surface 2428 abuts against the limiting surface 2784 of the connecting frame 270. At this time, the angle between the bracket 242 and the base 22 is 90 degrees. The friction generated between the components of the pivoting mechanism 28 causes the display screen 10 to be positioned at a set angle. The angle between the bracket 242 and the base 22 ranges from 0 to 90 degrees. Of course, it can be arbitrarily set according to actual conditions. The display screen 10 is rotated to rotate the rotating bracket 288 of the pivoting mechanism 28 about the axis b, the active spacer 290 and the follower washer 292 are relatively rotated, and the positioning protrusion 2904 of the active spacer 290 and the follower spacer 292 are The positioning holes 2922 cooperate with each other to improve the positioning feel of the rotating bracket 288 when rotated. The limiting member 2882 slides smoothly along the circular arc surface 2946 of the connecting frame 294 with the rotating bracket 288, and abuts against the circular arc surface 2946, and the pressing degree of the limiting member 2882 and the circular arc surface 2946 and the rotation of the rotating bracket 288 The angle is in a linear equation relationship such that the external force required to rotate the rotating bracket 288 remains substantially unchanged. The two ends of the circular arc surface 2946 are concave surfaces, and the limiting member 2882 slides 13 201014354 to stop sliding when moving to the concave surface, and realizes the rotation limit of the rotating bracket 288. In the present embodiment, the display screen has a rotation range of 〇 to 90 degrees around the axis b.
