INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a pivotal structure, and is particularly concerned with a pole-joined structure that is thinner than an electronic device. [Prior Art] With the demand for information technology and development, the traditional bulky desktop computer has gradually been replaced by a thin and portable computer. At present, the most common portable brain on the market is a notebook computer. Fantasy, its - has the advantages of small size and heavy I fresh and easy to carry, and the operation of some aspects of the month is not comparable to the desktop computer, but still has a good computing performance. - In terms of the overall structure of the notebooks currently on the market, most of them have a main unit for the motherboard, an output device and a main electronic component, and a mounting device = a liquid crystal display and other accessories. The top cover is typically pivoted to the top-side of the notebook computer and can optionally be clipped to the appropriate viewing angle or overlaid on the mainframe's keyboard. Therefore, the corresponding hinge assembly must be disposed between the upper cover and the main unit. The rotary shaft assembly transmits the upper cover of the shaft and the shaft hole and gives it the ability to turn it. There is also a tight fit between the shaft holes, such as loading and pressing parts such as cymbals, which prevent the upper cover from rotating by the friction between the paste members, so that the upper cover can be kept in the user without external force. Adjust the angle. In addition, in order to avoid collision of the LCD monitor due to the ± cover relative to the main body swing or other factors when carrying the notebook computer, the notebook computer is also provided to maintain the upper cover in the domain. The recording and transfer mechanism is roughly classified into ugly, that is, a hook-type switch assembly mounted on the front cover or the front end of the main unit, and the other is a clamp mounted on the rotating shaft group. The hook-type switch assembly can firmly fix the upper cover to the main body by the buckle function. However, the upper cover or the main body must be set to _ to accommodate the hook member=the private movement slot, which is quite an internal space. Moreover, the opening of the hook for the hook will make the appearance of the upper cover or the domain incomplete, which is quite disadvantageous for the notebook computer which pays attention to (4) short and beautiful appearance. As a result, more and more notebook computers have abandoned the hook switch assembly. The above-mentioned positioning members are integrated in the inner side of the rotating shaft assembly, which can relatively save the installation space of the mechanical parts and improve the aesthetics of the simple appearance, so that more and more small-sized pen Z-type computers adopt this design. . Related patents and patent cases have been quite f'for example, using torsion springs, blocking blocks, shrapnels, etc., and the user has to apply a large amount of force in a specific direction to open the top cover of the notebook computer. The upper cover is prevented from being opened by an external force. However, this type of positioning member is fixed: straight, formed inside the shaft assembly, and has no movable mechanism, and the support is provided by the effect of tight friction, so the two valleys are used under long-term use. Easy to wear 'causes the original positioning Wei loss 1 is not easy to repair during maintenance even 'can not be replaced or need to replace the entire casing. [Summary of the Invention] In the previous technique, it was recorded that the locating parts on the brain were not covered, and the valley was easy to wear and repaired or costly. In view of this, the main feature of the present invention is to provide a lion-connected structure for adding structure to make money and to facilitate the maintenance of a body and a cover and a limit block. The cover body is a pivotal structure according to the present invention, wherein the pivotal structure includes a sleeve, == configured on the body, and optionally covers the body or splits the electrons. The pivotal connection of the present invention is applied to an electronic device, and the second is a portable electronic device having a main body and a top cover of the sturdy display 11, and the main body is a portable electronic device. The upper cover of the cover body and the display cover of the portable electronic device. The sleeve has a position hole connected to one of the shafts, and the inner wall of the positioning hole is provided with a limit groove and a corresponding limit groove setting 邛. The supporting shaft is inserted into the shaft hole of the sleeve, and is slidably disposed on the reading shaft relative to the rotating 1-bit block in the shaft hole, wherein the t-cover body is in harmony with the main body 2 = the cam portion is misaligned The limit block 'slides the snap block and snaps into the limit groove' to provide resistance against the cover opening. The invention of the invention, the test _ in the cover body (domain) cover the main body (the display on the display time card from the limit of hunger shot, the seam can still maintain the cover σ in the field under the force to protect the display cover And the limiting block can slide on the support shaft, can reduce the mechanical parts under the provision of appropriate resistance, thereby improving the durability of the machine and the convenience of maintenance and replacement. ~ The following details of the present invention are described in detail in the embodiment. Features and advantages, which are sufficient for any skilled person to understand the technical content of the present invention and to implement 'and according to the contents disclosed in the specification, the patent system and the drawings, any familiar art The above-mentioned objects and advantages of the present invention are to be understood as a description of the present invention and the following description of the embodiments of the present invention. [Embodiment] ί S] 7 I335389 For the purpose of the present invention, _, is applied to an electronic device having a cover of a sturdy display, and a portable electronic device such as a mobile phone However, in the following embodiments, only the type of computer is a specific example. Only when applied to the eye, refer to "1st picture" to "drum 7 gang _ first phase 丨 θ", which is the pivot structure of the present invention. The first-real butterfly comprises a sleeve 2G, a support shaft 3g, a limit 34. The simple hair ride provides a German connection, the Wei is disposed on the electric device 10, and the electronic device 10 has a main body U and A cover body ^, the structure is used to connect the main body u with the cover body 12 /, the middle pile joint 11 骽 2 by the pivotal structure of the present invention ΖΓηη(4)# stealing the lion U, tender opening and main clamp-angle. The electronic device 1G is The aforementioned portable η is essentially the host of the portable electronic device, and the main clock $=cap is required to be charged::: the piece '_2 is substantially _= '', and the cover is used to carry the portable electronic Display of the device. See "i", "2", "3" and "5". The taotao 20 has a joint portion 2, a shaft hole 22 and a positioning hole ^, The shot joint portion 21 projects outwardly from the outer circumferential surface of the sleeve 20, and the shaft hole 22 communicates with the positioning hole 3. In the embodiment, the joint portion 21 is used for assembly (such as screw locking). The cover 12 of the electronic device 1 is fixed, and the sleeve 2 is fixed by the joint portion 21 to expose the cover 12 to the opening of the shaft hole 22. The shaft hole 22 is inserted through the sleeve = 20 ' and the shaft The hole 22 is substantially a circular hole perforation. A hole is formed between the shaft hole 22 and the positioning hole. The hole diameter of the shaft hole 22 is larger than the hole diameter of the positioning hole 23, and the level surface 24 faces the shaft hole 22. Λ and a cam ❹, wherein the cam portion 27#f is provided with a limiting groove 25 portion 27 that is slightly offset with respect to the limiting groove 25^, which is disposed in the limiting groove 25, that is, the cam product aa < The opening of the cam portion 27 is substantially the same as that of the flat Wei-he block 50 (10) Lai% of the rotating movement to the side of the Wei lion. The age groove ^ is provided on the side - the push top 26 ' wherein the push top % is disposed on the side of the opening of the limit groove 25 near the cam portion 27. Please refer to "Figure 1," "Figure 2" and "(4)". The support has a - joint portion 31, an end surface 32 and a guide groove %, wherein the joint portion Μ is supported by the support shaft 30; the outer circumferential surface is extended and extended, and the guide groove is supported by the end surface phantom direction (4) In the additional example, the joint portion 31 is used for assembly (such as screw locking) on the main body n of the electronic device 10, and the support shaft 30 is disposed on the main body γ' by the joint portion 31 and makes the branch 3G- The cover 12 is partially exposed. The portion of the cover body 12 that is exposed to the cover body 12 is used for inserting the shaft hole 22 of the sleeve 2, wherein the outer diameter of the portion of the support shaft 10 that exposes the cover body 12 is smaller than the inner diameter of the shaft hole 22, so that The outer peripheral surface of the shaft can be interfered with the inner wall of the shaft hole 22, and the branch shaft 3 can also rotate relative to the sleeve 20 in the shaft hole 22. The spacers 34 are stacked in the shaft holes 22 of the sleeves 2 and are in close contact with each other. When the support shafts 30 are inserted into the sleeves 2, the spacers 34 at the ends of the jaws 34 are in urgent contact. The end face 32 of the support shaft 30 and the level face 24 of the sleeve 20 are supported. Therefore, when the sleeve 20 of the support shaft 30 is pivoted relative to the support shaft 3G, the aforementioned contact domains generate a frictional force. Please refer to "Figure 1," "Figure 2" and "Figure 3". The limiting block 5 is slidably disposed on the support shaft 3〇, and the limiting block 5〇 has a guiding portion 9 1 S1 52 and a retreating portion 53. The guide portion 51 is placed in the guide groove 33 of the support (4) to slide in the groove 33, and the edge of the guide groove 33 projects into the guide portion 51. When the limit 5 is pushed by the external force, the guiding portion 51 can guide the limiting block 50 along the guiding groove. In this side, 'Nan 3Q's guide groove is too large, so that the limit block is 5° roughly butterfly (four) is parallel to the main body η. 5 (4) is torn to the positioning hole Μ人筒 2 shaft hole 22 when the limit The block 5〇 protrudes into the cam portion 27 of the sleeve 20 and the π and the Wei part% are divided into the mosquito bit hole 23. Please refer to "1", "3", "5", "6th" Figure "and Figure 7". In the pivotal structure, the spacers 34 are in close contact with each other and are in urgent contact with the end surface 32 of the support shaft 3〇 and the level surface 24 of the sleeve 20, plus the peripheral surface and the perforation 22 of the support (4) portion. The inner walls interfere with each other, and the static frictional resistance generated on the contact surfaces can resist the gravity received by the cover 12 itself. Therefore, after the user opens the cover 12 to the angle, the button 12 itself can be twice. When the cover body 12 is subjected to the above-mentioned static frictional resistance, the cover body 12 is pushed to be rotated relative to the main body 11, so as to facilitate the user to adjust the display when the user pushes the cover body 12 toward the cover main assembly. With respect to the support 3〇_, the cam portion 27 and the sleeve 2G are pushed against the insertion portion 52' of the limit block 50 to slide the limit fabric 50 and snap into the limit groove 25 of the positioning hole 23 (refer to "Fig. 7" ")) so that the cover 12 is kept closed to the main body u. At the same time, the edges of the limiting block 50 and the limiting groove 25 interfere with each other, i.e., the top and bottom portions 53 interfere with each other to resist the opening of the cover 12. Therefore, when the cover body 12 is completely covered by the main body 10, the pusher top 26 and the cam block 27 respectively abut against the two of the limit blocks ^, so that the cover body 12 is not affected by the electronic device 1 () The vibration is opened to provide protection. When the user wants to open the cover 12 to pivot the cover 12 from the cover body toward the main body U, it is necessary to use the force to overcome the static friction resistance of the limit block to "cover the cover 12". Open it. When the user pulls the cover 12 away from the main body 11 after the force is applied, the sleeve 20 will push against the top of the pusher to push the top part _ 2 〇 to rotate and cover (4) the silk surface ^ Μ face dislocation groove 25 , Basin I refer to Figure 8 "Lion" is the second embodiment of the purchase structure, minus '^ structure and surface - the actual relationship _, the rest of the two embodiments of the Wei will not be described. Referring to FIG. 8 again, in conjunction with the electric diagram, in the present embodiment, the sleeve 2 is fixed to the sub-piercing raft 11' by its joint portion 21 and the branch shaft 30 is joined by its joint portion 31. The body 12 is fixed to the electric=Η). When the user pushes the cover 12 toward the cover body n, the %='^_G will rotate relative to the sleeve 20, and the top portion j of the limit block j supports the shaft 30 to be rotated and the push top 26 of the positioning hole 23 Pushing, the limit block 2; the limit groove 25 of the clamp hole 23. At the same time, the edge of the limiting block 5〇 and the limiting groove interfere with each other, that is, the top retreating portion 53 and the pushing top portion interfere with each other to prevent the cover 12 from being closed to the main body u. Therefore, when the cover member is fully coupled to the main body 11, the raft is as. The joint structure can also be provided to make the appropriate side. § When the user hardly pivots the cover body 12 and pivots the cover body 12 from the position of the cover body η toward the main body u, the branch will be phased by the sleeve 1335389. The tube 2 turns, and the limit block The top of the 50 (4) will be pushed by the ejector 26 of the positioning hole 23 as the shaft 30 rotates, so that the limiting block 5 slid and exits the limiting groove ^, and the cover 12 can be opened. Please refer to FIG. 9 and FIG. 1 for the third embodiment of the frame connection structure of the present invention. The specific structure of the frame connection structure is substantially the same as that of the first embodiment described above, and only the differences between the two embodiments are as follows. Explain it, and the rest will not go into details. In this embodiment, the guide groove 33 of the support shaft 30 is substantially perpendicular to the main body u, and the limiting groove 25 of the inner wall of the positioning hole of the sleeve 2 and the cam portion 27 are also arranged corresponding to the sliding manner of the limiting block 5〇. , the limiting block 50 is slid substantially perpendicular to the main body u on the support shaft 3〇.
