Description of the Invention: [Technical Field of the Invention] The present invention relates to a rotary device, a rotary positioning device for rotational positioning. Two-way technology is available. [Prior Art] Many products require rotational positioning to provide different material requirements, changes, and functions. 'This is either a digital video disc player (DVE), a 1U camera, a toy, a mobile phone, a stepper, a laptop, a liquid crystal display, a personal digital assistant (PDA), a digital camera or a mobile phone. Product or non-electronic products are widely used as technical solutions for rotating positioning devices or rotating mechanisms. For electronic products, such as notebook computers, LCD monitors, PDAs, digital cameras or mobile phones, rotary positioning is often used. The device allows the screen to be rotated in the plane of its main body. Please refer to Figure 9, Taiwan Patent Publication No. 49513, "Flat Display Device and Rotating Mechanism", which discloses a flat display state of a notebook computer i 〇 The computer host 120 is pivotally connected to a rotating structure 13 〇 to rotate the flat display 110 relative to the computer host 120. Referring to FIG. 10, the rotating mechanism 130 is fixed to the computer main body 120 by a fixing base 131 (please refer to FIG. 9), and is pivotally connected to the flat display 11 by a rotating base 132. The holder 13 1 has a cylindrical body 139 having a through hole 133 defined in the radial direction of the inner wall surface of the cylindrical body 139. The rotator 132 has a cylindrical body 135 disposed in the through hole 133 of the fixing base 131. The ribs 136 are recessed inwardly of the cylindrical body 135. Elastic members 137 are embedded in each of the slots BA, and each of the elastic members 137 has a flange 138. The flanges 138 of the two-component members 137 are respectively inserted into the corresponding recesses 136, so that the flat-panel display 11 is rotated and positioned. However, since the flange 138 and the groove 136 are in a concave-convex engagement position, the flange 138 and the groove 136 are often not closely matched due to the manufacturing process, thereby making the protrusion The edge 138 is loosely engaged in the concave lift 136, so that the flat display will swing up and down or left and right, and the position cannot be stably fixed. At the same time, if the two flanges 138 are to be snapped into the respective grooves, the relative positions of the slots 134, the flanges 138, and the grooves must be accurately calculated at the time of manufacture. If the position of one of the two is deviated, only one flange 138 is caught in the groove 136, and the other flange 138' is located outside the other groove 136, so that the flat display cannot be cut. Accurate positioning, as shown in Figure 11. Referring to Fig. 12, Taiwan Patent Publication No. 551787 "Electronic device with rotating positioning I" discloses another rotary positioning device. The rotary clamping device 200 includes a rotating base 220, a positioning member 230, two elastic pieces 4, a bearing seat 250, and a plurality of washers. The rotating seat 22 〇 extends downwardly from a cylindrical sleeve 222. The positioning member 230 is mounted downward on one side of the movable seat 220. A through hole 252 is defined in the middle of the bearing seat 25 以 to respectively seat the sleeve 222 of the rotating base 220 so that the rotating seat 22 旋转 can rotate around the bearing seat 250. Each of the two sides of the bearing seat 25 extends outwardly from a shoulder 254, and each shoulder 254 defines an opening 256. Each shoulder 254 18025 (Revised) 6 1268983 has a slot 258 at the end of its opening 256 for inserting the spring 24 therein. After the positioning member 23 is mounted on the rotating base 22, and the sleeve 222 of the rotating base 220 is installed in the through hole 252 of the bearing seat 25, the rotating base 220 can surround the bearing The seat 250 is rotated, and the positioning member 23 is respectively engaged in the elastic piece 24 装 mounted on both sides of the bearing seat 250, so that the rotating seat 220 is stably fixed. However, the rotating base 22 of the above-described rotary positioning device 200 can only be rotated at most 18 degrees around the bearing 1 250, and can only be rotated by 18 degrees in one direction. Therefore, when the rotating seat 220 is required to rotate about 18 degrees around the bearing seat 25, or the rotating seat 220 is required to rotate bidirectionally around the bearing seat 25, the rotary positioning device 200 is powerless, so that The scope of application is greatly limited. It is known from the above that the above-mentioned prior art has a problem that it can only rotate in one direction, the angle is limited, and the degree of squatting is poor. Therefore, in the above-mentioned problems, how to provide a rotary positioning device that can be bi-directionally rotated, has an elastic rotation angle, and can be surely positioned has become an issue that the industry is currently trying to solve. [Summary of the Invention] In addition, the above-mentioned conventional technology forms a positioning mechanism by using a positioning device to form a positioning mechanism by using a positioning post on a spring piece or a spring plus a ball to generate an interference mechanism, thereby repeating the positioning. The components are made of zinc alloy, and the structure of the rotating seat and the bearing seat is mostly soft and easy to wear. Therefore, the members of the prior art are prone to increase the wear due to frequent sigma friction, resulting in poor positioning mechanism. The main object of the present invention is in view of the above-mentioned disadvantages of the prior art. 18025 (Revised) 7 1268983 provides a rotationally positionable device that is rotatable in both directions.

The third collar 50 is attached to the second collar 4 as shown in Fig. 3. As described above, before the second lug 54 of the third collar 50 abuts against the convex portion 44 of the second collar 40, it may have been rotated clockwise or counterclockwise (β-θ54)/2 angle. The third collar 50 can be rotated clockwise or counterclockwise (point - θ 54) / 2+ (180 - (α + θ 42) / 2) degrees. Therefore, when the second (5〇+054) degrees, α=(9〇·θα degrees, and the second lug 54 and the positioning portion 42 are at the initial positions, the third collar 5〇 can achieve a two-way rotation of 18 degrees. However, when the third collar 50 is rotated 180 degrees in either direction, it can be rotated 360 degrees in the opposite direction of the reverse 18025 (corrected) 14 1268983.

In the present embodiment, the protrusion 54b extending downward from the rotating member is used as the toggle portion, but the protrusion 5 may be other protruding structures that can respectively abut the side edges of the protrusion, instead of In other embodiments, the protruding post may also be selected as the protruding knot extending downward from the third collar as the second wearing portion, which is 17 18025 (Revised) 1268983. To move the convex portion 44. The assembly steps and the rotation of the rotary positioning device 1 Ob of the preferred embodiment are the same as those of the first preferred embodiment, and are not described herein again. The fourth preferred embodiment is shown in FIG. 7. The rotary positioning device i〇c of the preferred embodiment is substantially the same as the rotary positioning device 1 of the first preferred embodiment. The preferred embodiment and the first The preferred embodiment differs in that the number of positioning collars is increased. As shown in Fig. 7, a fourth collar 40c is added between the second collar 4〇 and the third collar. The fourth loop tearing is used as a positioning collar, and the structure of the fourth loop 40c is the same as that of the second loop 4〇. In this embodiment, the fourth set of loops is supported by the upper end surface of the first collar 16 and the outer surface of the outer surface of the first collar 30 is respectively disposed with a convex portion 44c and outwardly at an appropriate position. A positioning portion 42c extends downward. The upper end surface of each convex portion 44c is flush with the upper and lower end faces of the second collar.
