New description: [New technical field] This creation is a simplified structure of the hinge, which is a kind of installation between the upper cover and the base of the cover type electronic device to enable the upper cover to open and close relative to the base. [Prior Art] In the prior art splicer, there is an element which can produce a positioning effect, and an element which can generate a torsion effect by rubbing against each other. For example, as shown in the publication No. 2005/0039301, the positioning effect is provided by the cooperation of the concave positioning block and the convex positioning block which generate relative rotation, and the two positioning blocks are pushed by a plurality of elastic laminations to keep the two positioning blocks. Tightly fitting, and thus providing a torsional effect, a similar structure is also applied in U.S. Patent No. 7,171,247, U.S. Patent No. 2,6/35,353, U.S. Patent Publication No. 2005/0155183, U.S. Patent No. 6,862,779 Patent case, U.S. Patent No. 7,082,642, and U.S. Patent No. 7,219,393. For example, as shown in U.S. Patent No. 5,269,047, the use of a plurality of disc-shaped shrapnel stacks and then tightens the remaining members so that the remaining members rub against each other when pressed against each other to provide a torsion force, similar structure. It is also used in the U.S. Patent No. 5,269,047, U.S. Patent No. 5,772,351, U.S. Patent No. 5,913,351, U.S. Patent No. 5,597, file, U.S. Patent No. 5,940,936, U.S. Patent No. 6,163,928. In terms of the functions that the hinge should provide, positioning effect and torsion are two important functions that are indispensable. However, as far as the prior art 3 M395993 structure is concerned, the positioning effect and the torsion effect are different. The structure of the two systems is bound to increase the volume of the prior art hubs. In today's portable electronic devices, the requirements of light and thin, often only allow the hinge to occupy a length within a few centimeters. Space, too many components of the hub will not meet the needs of today's portable electronic devices, and only a single function can not meet the needs of users. Therefore, the prior art hub does have its need for improvement. [New content] • In view of the above-mentioned shortcomings of the prior art, the author has improved the hub to achieve the most complete function with the most simplified structure. In order to achieve the above-mentioned creative purpose, the technical means adopted by the present invention is to design a hinge with a simplified structure, which comprises: a pivot shaft having a crown portion and a set of posts extending from the crown; a positioning elastic piece The locating elastic piece is rotatably sleeved on the outer side of the pivoting rod, and one end of the positioning elastic piece extends to form a connecting piece body, and the other end has an elastic portion formed by bulging to the side surface thereof, and the elastic portion has both end portions, and The elastic portion of the ridge is formed with a positioning convex portion on the side of the bulge, and the positioning convex portion is formed between the two end portions; and a positioning gasket is rotatably slidably sleeved on the pivoting socket of the pivot rod. The sheet has a first side surface and a positioning concave portion, and the first side surface of the positioning gusset abuts against the positioning convex portion of the positioning elastic piece, and the positioning concave portion is concavely formed on the first side surface of the positioning gasket and the positioning convex portion of the positioning elastic piece Corresponding; and a fixing member which is sleeved and fixed outside the pivoting sleeve to close the above components. 4 Furthermore, the present invention may also adopt another technical solution, which includes: a pivot shaft having a crown and a set of posts extending from the crown; a positioning elastic piece rotatably sleeved on the pivot Outside the sleeve of the shaft, the positioning elastic piece ends to form a connecting piece body, and the other end has an elastic portion formed by bulging toward one side of the basin. The bulging direction of the elastic portion faces the crown portion; The sleeve that is non-rotatably slidably sleeved on the pivot

It should be noted that in the present embodiment, the portable electronic device is more stable during the process of opening and closing the cover 60 by the arrangement of the additional connecting piece 4A. This is because when the positioning elastic piece 20 is rotated, the two end portions 22 of the elastic portion are rubbed against the first side surface 111 of the pivot, but in the present embodiment, one side and the pivot of the additional connecting piece 4 (10) A are used. The first side is rubbed, so the cover is more stable than the first embodiment. • Therefore, this creation can effectively simplify the overall structure by positioning the shrapnel 20, 20A itself to provide both torque and positioning. In addition, those skilled in the art can implement various contours of the concave cam surface in the prior art on the positioning elastic piece and the positioning pad of the present invention to achieve various torque changes. That is to say, the positioning pad positioning recessed portion of the present invention and the positioning convex portion of the positioning elastic piece can have other unevenness changes, which are not deviated from the spirit of the present creation. In addition, those skilled in the art can also make other changes after referring to this creation. As shown in FIG. 12, the positioning convex portion 23b of the positioning elastic piece 20B faces the first side surface U1B of the crown portion 11B of the pivot 10B, and the positioning spacer 3〇b is also reversely disposed to position the positioning spacer 30B. The convex portion 35B corresponds to the opposite side of the positioning convex portion 23B of the elastic piece 20B, and the effect of the creation can also be achieved, that is, the positioning elastic piece itself can provide the dual functions of torsion and positioning. However, as described above, the positioning elastic piece 2〇B in the present embodiment is capable of providing positioning and friction with the first side surface U1B of the crown portion 11B of the pivot 10B to easily detract from the life of the positioning elastic piece 20B. Thus, the modified embodiment of Fig. 13 is also an example of an extension that is readily available to those skilled in the art after reference to this creation. Referring to the circle 13, the additional connecting piece 4〇〇c is disposed as a friction plate between the first side mc of the crown 11C of the pivot ioc and the positioning elastic piece 20C, wherein the positioning elastic piece 2〇c The positioning protrusions are oriented toward the first side surface luc of the crown 2 nc, and the positioning spacers 3〇c are also disposed oppositely to position the positioning protrusions 35C of the positioning tabs 3GC corresponding to the positioning protrusions 23C of the spring pieces 2()c. On the reverse side, in this way, the additional attachment piece _c drives the positioning elastic piece 20C to rotate when the frame is pulled 1〇c, and the positioning convex part 23C of the positioning elastic piece 2〇c is not directly connected to the crown of the frame axis 1〇c. The first side is self-friction, so that the life of the positioning elastic piece 20C can be effectively extended.
