Description of the Invention: [Technical Field] The present invention relates to a pivoting positioning device for a display screen, and more particularly to a pivoting display of a display screen that can be positioned after pivoting on a base Device. [Prior Art] As shown in FIG. 6, a pivoting device 9 for a display screen has a base 9 1 and a plurality of limit bars 9 1 1 are disposed on the base 9 1 . The base 9 1 is provided with a turntable 9 2 having a plurality of arcuate holes 9 2 1 corresponding to the limit bars 9 1 1 , and the display screen is fixed at a central position of the turntable 92. Thereby, the display screen is fixed on the turntable 92 and can be rotated within the limit range of the arc hole 9 2 1 of the turntable 9 2 and the limit rod 9 1 1 on the base 9 1 and displayed The curtain only falls on the turntable 9 2 according to its own weight, so that the display screen can be separated from the original position only by a slight force, which is easy for the viewer to easily observe when the display screen is subjected to external force when watching the program. Rotating, causing the viewer's viewing angle to be affected. Therefore, in order to solve the above problem, it is necessary to provide a display screen pivoting device 9 that can be positioned after being rotated to an appropriate position without being easily affected by external forces to affect viewing. The viewing angle of the person. SUMMARY OF THE INVENTION The main object of the present invention is to solve the above problems and provide a pivoting and positioning device for a display screen. When the display screen is positioned at an appropriate angle when each of the locking portions is engaged with each positioning portion, The positioning effect can be achieved, and it is not easy to cause displacement due to improper force. A secondary object of the present invention is to provide an adjustable resistance adjusting unit between the display and the base during pivoting, thereby preventing the display screen from being separated from each other during the rotation of the display screen. Not too much rotation. For the purpose of the foregoing, the present invention includes: a base; a pivoting member is coupled to the base, and at least one positioning portion is disposed around the pivoting member; a pivoting member The pivoting member is connected to the display screen and sleeved on the pivoting member, and the pivoting member has at least one locking portion corresponding to the pivoting member positioning portion. In addition, the present invention further includes: the base has a screw protruding from a central position, and the screw is threaded with a turntable, the turntable is pivotable on the base, and the pivoting member is located above the turntable The wear setting is located at the screw, and the pivoting wire is disposed at the bottom of the pivoting member to be coupled with the turn-on _,: ° accommodating portion, and a resistance adjusting unit TT is provided for the above-mentioned Other purposes and advantages are not difficult to understand from the detailed description of the embodiment and the drawings. Of course, the present invention differs in some of the components, or the arrangement of the components, but the selected embodiment is described in the specification and its construction is shown in the drawings. W. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [Embodiment] 200902898: The drawings shown in Figs. 1 to 5 are the limitations of the structure of the present invention. Ningyue does not provide a pivotal positioning device for the display screen, as shown in Fig. 1, which includes: 2, two 'on the base 1 - combined with The pivoting member embodiment Γ ring is provided with at least a positioning portion 21, and the opposite center positioning ring 2 is provided with two opposite positioning portions 21 in the surrounding ring. The pivoting member 3' is connected to the display screen and sleeved on the pivoting member 2 = pivotable, and the member 3 has at least a locking portion 31 for engaging the habitat member ^=卩21 In this embodiment, the locking member 3 of the pivoting member 3 is positioned to be positioned with the positioning portion of the pivoting member 2, and each of the locking portions 31 is limited by - In the ί = 1 an elastic element 3 1 1 pushes against the top member 3 1 : in the present embodiment, the elastic member 3 1 1 is a magazine, and the abutting member 3 1 2 is A steel ball. It can be seen from the above that the display screen is connected to each positioning portion 2 by the pivoting member 3 and the pivoting member 2 to be positioned at a certain angle. Thereby, the effect of positioning is achieved and it is not easy to be displaced by a slight force application. Of course, 'there are still many examples of the present invention', and only the details change. 第 Refer to FIG. 3 and FIG. 4, which is the In the second embodiment, the display screen has a suitable torsion force during the rotation process, so that when the display screen is rotated, the locking portions and the positioning portions are prevented from rotating excessively at the moment of 200902898, wherein the The pivoting member 2A is provided with twelve positioning portions 2丄 at equal intervals around the circumference of the pivoting member 2A, and the spacing angle of each of the positioning portions 2 i is thirty degrees (the angle of the spacing here is only one embodiment, and is designed The locking portion 31 of the pivoting member 3 is the same as the structure of the first embodiment. In addition, the base 1 has a screw 凸 at a central position. , the system is coupled with the base 1 , and in the embodiment of the towel, the tool There are two opposite sections 1 ii, and the screw is threaded through a turntable 4, and the turntable 4 is pivotable on the base 1. The pivoting member 2A is located above the turntable 1 and is disposed therethrough. In the screw machine 1, and in the embodiment, the pivoting member 2A has a perforation 2 2 which can cooperate with the screw 1 1 1 ι 1] 1 1 1 , so that the pivoting member 2 can be The pivoting member 2a has a receiving portion 23 for providing a resistance adjusting unit 5. The resistance adjusting unit 5 includes a plurality of elastic pieces 5 1 and a nut 5 2 , each of which 2 The elastic piece 51 is threaded through the screw 2 and placed in the receiving portion 2 of the pivoting member 2a, and the screw 5 is screwed on the screw 1 i to tighten each The elastic piece 5 i, and the _ piece 3 wire is disposed on the pivoting member 2 A, and the bottom of the pivoting member 3 is coupled with the turntable 4 to be cooperating. 曰 From the above, as shown in FIG. 4, Each of the elastic pieces 5丄 can be compressed by adjusting the nut 5 2 provided on the screw 11 to increase the rotational resistance of the turntable 4 between the pivoting member 2A and the base 1 while rotating The pivoting member 3 must be linked The turntable 4' can be adjusted by adjusting the nut 5 200902898 2 to prevent the display screen from generating resistance when rotating. The display screen is prevented from being separated from each other during the rotation process. 2 seconds; 2 lt 々 亦可 亦可 亦可 亦可 亦可 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 The shape of the arc hole 4 i, the position of each of the arcuate holes 41 corresponding to the turntable 4A has a number ===, and each of the limit rods 12 is opposite to the library, and the χ女赭 has no dry 1 2 holes 41, _Yu:;:Wing: Disk =: The structure in which the resistance can be increased in the embodiment can be adjusted to a more appropriate rotation within the range of rotation == The problem of excessive rotation of the display screen caused by the force applied.
