Please refer to FIG. 5 and FIG. 6 . FIG. 5 is a schematic diagram of adjusting the range in which the first stop element 46 rotates the positioning plate 42 relative to the first fixing member 38 according to the present invention, and FIG. 6 is an adjustment in FIG. The first stop element 46 is followed by a schematic view showing that the screen 32 is adjusted. When the positioning plate 42 rotates relative to the first fixing member 38 to slide the first positioning post 44 in the first arc groove 40 to the vicinity of the first channel end point P1, the screw 48 of the first stop member 46 can be stopped. The first positioning post 44 is used to limit the range in which the positioning plate 42 rotates relative to the first fixing member 38. Therefore, by rotating the screw 48 of the first stop member 46 to change its protrusion and shielding the length of the first arc groove 40, as shown in FIG. 5, when the screw 48 is screwed into the first arc groove 40, a stroke is made. In the case of D, the sliding limit point of the first positioning post 44 near the end point P1 of the first channel of the first arc groove 40 is changed, so that the limitation range of the rotation of the first positioning post 44 relative to the axis is smooth. The hour hand direction is adjusted by an angle ΔΘ. As shown in FIG. 6, if the positioning plate 42 is rotated relative to the first fixing member 38 to bring the display screen 32 into the horizontal mode, and at this time, the first positioning post 44 slides into the first slot in the first arc slot 40. Near the end point P1 of the track, and the screw 48 of the first stop element 46 abuts the first positioning post 44, in the direction in which the user views the display screen 32 (as viewed from the front of the display screen 32), the display screen 32 is displayed in the clockwise direction. When the angle ΔΘ is tilted and the level is not reached, the screw 48 can be screwed into the first arc groove 40 by the 1305814 as shown in FIG. 5, so that the first positioning post 44 is opposite to the axis. The rotation limit is adjusted in the clockwise direction (as viewed from the rear of the display screen 32) by the angle ΔΘ. At this time, in the direction in which the user views the display screen 32 (as viewed from the front of the display screen 32), the display screen 32 can be reversed. When the angle of the hand is rotated by the angle ΛΘ, the state of reaching the full level is achieved, that is, the correction of the horizontal angle of the display screen 32 is completed. In contrast, when the user views the display screen 32 (as viewed from the front of the display screen 32), the display screen 32 is tilted by an angle ΔΘ in the counterclockwise direction to rotate the screw 48 away from the first arc slot 40. The adjustment range of the first positioning post 44 relative to the pivot of the shaft is adjusted in a counterclockwise direction (as viewed from the rear of the display screen 32), and will not be described in detail herein. Please refer to FIG. 7 and FIG. 8 . FIG. 7 is a schematic diagram of adjusting the range in which the second stopper element 50 rotates the positioning plate 42 relative to the first fixing member 38 according to the present invention. FIG. 8 is a diagram of FIG. After the second stop element 50 is adjusted, the screen 32 is adjusted. When the positioning plate 42 rotates relative to the first fixing member 38 to slide the first positioning post 44 in the first arc groove 40 to the vicinity of the second channel end point P2, the screw 52 of the second stopping member 50 can be stopped. The first positioning post 44 is used to limit the range in which the positioning plate 42 rotates relative to the first fixing member 38. Therefore, by rotating the screw 52 of the second stopper member 50 to change its protrusion and shielding the length of the first arc groove 40, as shown in FIG. 7, when the screw 50 is screwed into the first arc groove 40, a stroke is made. At D', the first fixed-position post 44 is changed at the sliding limit 11 1305814 near the second channel end point P2 of the first arc slot 40, so that the first positioning post 44 is rotated relative to the axis 0. The limit is adjusted by an angle ΔΘ' in a counterclockwise direction. As shown in FIG. 8, if the positioning plate 42 is rotated relative to the first fixing member 38 to bring the display screen 32 into the vertical mode, and at this time, the first positioning post 44 slides into the second slot in the first arc slot 40. When the track end point Ρ2 is near, and the screw 52 of the second stop element 50 is stopped against the first positioning post 44, when the user views the display screen 32 (as viewed from the front of the display screen 32), the display screen 32 is reversed. When the needle direction is inclined by the angle ΛΘ', and the state is not completely vertical, the screw 52 can be screwed into the first arc groove 40 into the stroke D' as shown in FIG. 7 so that the first positioning post 44 is opposite to the first positioning post 44. The limitation of the rotation of the pivot is adjusted in the counterclockwise direction (as viewed from the rear of the display screen 32) by the angle ΛΘ', and the screen 32 is displayed in the direction in which the user views the display screen 32 (as viewed from the front of the display screen 32). The angle ΔΘ' can be rotated in a clockwise direction to reach a completely vertical state, that is, the calibration of the vertical angle of the display screen 32 is completed. In contrast, when the user views the display screen 32 (as viewed from the front of the display screen 32), the display screen 32 is tilted by an angle ΔΘ' in the clockwise direction, and the screw 52 can be unscrewed away from the first arc slot 40. The adjustment range of the first positioning post 44 relative to the pivot of the shaft is adjusted in a clockwise direction (as viewed from the rear of the display screen 32), and will not be described in detail herein. Similarly, if the range of rotation of the display screen 32 relative to the X axis is to be adjusted, the length of the second arc groove 58 can be protruded by adjusting the screw 62 of the third stop element 60 and the screw 66 of the fourth stop element 64. In order to limit the range in which the second positioning post 12 / 1305814 54 slides in the second arc groove 58, thereby adjusting the limitation range of the rotation of the second positioning post 54 relative to the axis O', thereby changing the second fixing member 56 relative to the base The limitation range of the rotation of the seat 34 is the same as the principle of adjusting the first stop element 46 and the second stop element 50, and therefore will not be described in detail herein. Compared with the conventional display device, the display device of the present invention uses the stop mechanism to fine-tune the rotation range of the display screen, so that the display screen can not be maintained due to assembly tolerances during mass production of the display device. A consistent horizontal or vertical angle problem can also solve the problem of increasing the cost of the mold in order to achieve the assembly tolerance. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the patent application of the present invention should fall within the scope of the present invention.
