The above objects and advantages of the present invention will be readily understood from the following detailed description of the embodiments of the invention. The following examples will be described in detail with reference to the drawings: [Embodiment] Referring to the second and second B drawings, the present invention provides a card rotation shaft, which comprises: a central sleeve portion 10, A hollow cylindrical shape, the central sleeve portion 1 has at least an inner surface 11, an outer surface 12, a locking portion 13, an angle stop portion 14 and a set of section grooves 15; The portion 14 has a first stop edge i4i — and a second stop edge 142 . The first shaft portion 20 has a first outer portion 21 , a wall portion 22 , a first extension portion 23 , and a first sulcus 24; a shackle fixing portion 221 for securing the locking portion 13 is provided on the wall portion 22, and the central sleeve portion 10 is connected to the first shaft portion 20 In one piece, the first extending portion 23 has a first extending outer surface 231 and a first extending inner surface 232, and the first extending outer surface 231 substantially corresponds to the inner surface of the central sleeve portion 10; The second rotating shaft portion 30 has a second outer connecting portion 31, a sliding limiting portion 32 and a second extending portion 33; the sliding limiting portion 32 has at least a first limiting edge 321 and a second limiting edge 322. The angle stopping portion 14 is rotatable between the first limiting edge 321 and the second limiting edge 322 by a first predetermined angle 01. The second extension 7 M334615 4 33 is insertable into the first extended inner surface 1 of the first extension portion 23, such as the first extension portion 23, and is relatively rotatable (such as the third and fourth A diagrams). The operation of the angle stop portion 14 is located between the third limiting edge 321 and the second limiting edge 322, and can be rotated on the sliding limiting portion 32. (may be respectively toward the first-limit edge 321 and the second limit edge 322 - single ^ (four) degrees ΘΑ), the range of rotation is the first-predetermined angle <9 1, Tian Ran, can also change the angle The stop portion 14 is sized to change the angle of rotation of the fan (as shown in the fourth and fourth B drawings, the size of the angle stop portion 14 is changed from a first size D1 to a second size D2, The range of the rotatable angle is also changed from the first rotation angle Θ1 to a second predetermined angle 02). The fourth C diagram of the wheat is the second action of the angle stop portion 14, which is in contact with one of the second limit edge 321 or the second limit edge and the edge 322, so that the angle is 4 4 /, The unidirectional rotation of the sliding limit portion 32 is performed within a range of a third predetermined angle (the angle urging portion 14 is thinner than the first limiting edge 321 after installation, so that the The first limiting edge M1 makes a one-way direction toward the second limiting edge 322: rotation), which is commonly used in mobile phones or notebook computers, and the rotation angle is about 〇 degrees to 180 degrees. ). In practice, the locking fixing portion and the locking fixing engagement portion are a concave-convex fitting structure. In summary, the advantages and effects of this creation can be summarized as follows: m is easy to adjust the tightness of the shaft. As shown in the second and second B drawings, the sleeve section and the first section of the creation are both It has the effect of fine-tuning the size, making the whole structure more assembled after assembly, and the shirt transforms the tightness of any part, that is, the whole shaft. 8 M334615 W can be used for a large external force. As shown in the third and fourth A diagrams, the present invention directly achieves the angle limit stop portion 14 on the central sleeve 410 by the first limit edge 321 and the second limit edge 322 on the hinge portion 30. The one-degree limit is integrated with the body, instead of installing a foreign object to define the angle, so that it can withstand external forces. 'Visit P' is easy to assemble. The design adopts a three-piece combination design, which firstly fits the central sleeve portion into the body, and then mounts the second shaft portion, and the assembly process can be matched with the sleeve portion and the The first step is to adjust the fit size, and it is quite convenient to assemble. The above is only a detailed description of the present invention by way of a preferred embodiment, and any simple modifications and changes made to the embodiment are not deviated from the spirit and scope of the present invention. / / The company's detailed _ 'Know, knowing the skill of the artist, the Japanese can be achieved in the creation of the month can be reached."
