The position bumps 124 cooperate to limit the upper two sides of the insertion shaft 2〇: the condensing frame 3〇 is sleeved and fixed on the pivot 20, and the two Sr of the rotating frame shape: the perforation I is worn... Referring to Fig. 2 ς π - W and solid: the second side of the connecting wing 12 is fixed, the concave positioning piece 40 is adjacent to the sleeve side surface 42 and a second, the concave positioning piece 4° has a center hole 41, - oriented The sleeve wing 12: the surface 43 'the first side surface 42 of the concave positioning piece 40 — the top surface 1 23, the fixing pin 44 is formed in the concave position piece 4 - (2), the concave positioning: 42 And the fixing hole first-positioning groove 45 fixed to the sleeve wing 12, the second side 43 is formed with a pair of symmetrical pairs of the second positioning groove 46, and the pair of 6 »^ The first positioning protrusion 47 is disposed between the first and second positioning grooves 45, 46, and the two sides of the first positioning protrusion 47 have inclined surfaces respectively. A first axis 451, a second axis 461, and a third axis 471 are defined on the second side 43 respectively. The first axis 451 extends through the center of the first positioning groove 45, and the second axis 471. Pui line through the central recess 46 of the first positioning 'a third suction line 471 through the first - the center of the positioning projections 47, in the preferred embodiment, the 45 degree arc occupied by the first positioning groove 20 degrees. Φ, as shown in FIG. 2, FIG. 3, FIG. 4, FIG. 6 and FIG. 7, the convex positioning piece 50 is slidably engaged on the pivot shaft 2, and the convex positioning piece 5 has a central hole 51. a first side surface 52 and a second side surface 53. The central hole 51 of the protruding positioning piece 50 can be a non-circular hole for engaging and slidably disposed outside the non-circular rod portion 21 of the pivot 20. The first side surface 52 of the convex positioning piece 5 is abutted against the second side surface 43 of the concave positioning piece 40. The first side surface 52 of the convex positioning piece 5 is formed with a pair of symmetrical second positioning protrusions "and a pair The second positioning protrusion 54 corresponds to the first positioning groove 45 of the concave positioning piece 4〇, so the second positioning protrusion 54 preferably has a curvature of 2 degrees. The two side edges of the first and third positioning protrusions 54 and 55 respectively have inclined surfaces, and the second side surface 53 of the convex positioning piece 50 is formed with a block 56, and a silencing pad 57 is fixed to the convex positioning piece 5〇. The second side of the self-locking pad 57 can have a notch 571 to be engaged with the block 56. The muffler 57 is made of stamping, so that it can have higher precision; The sheet and the convex positioning piece 50 are generally made of coffee, so the accuracy of the center hole 51 is poor; therefore, the concave positioning piece correction and the convex positioning piece 50 with poor precision during the rotation of the frame member are likely to be different from the rod portion 21. After the 7 M400739 is pressed and snapped with high precision, the missing slot 571 on the muffler pad 57 is used to avoid the generation of the abnormal sound, and the convex positioning piece 5〇 can also be protected. The above-mentioned elastic cymbals 60 are stacked on the shank of the pivot wheel (10), and the second side of the elastic cymbal cymbal ejector locating piece 5G or the muffler cymbal is used to position the slab 50. The opposite sides 52, ^ of the concave piece 4q are in close contact with each other. The fixing piece 7G is placed at the end of the rod portion of the material 2q to clamp the fixing member 7 of the fixing member 7 to be screwed. In the preferred embodiment, the nut is frictionally worn by the nut portion of the shaft 2, which is disposed on the shaft of the pivot shaft 2, and is disposed in the socket. The wing 12 and the concave positioning "the first side 42" are dissipated: The spacer 80 is disposed between the elastic cymbal 60 and the fixing member 7A.

請參閱圖9至圖12所示，當上蓋90相對於底座91閉 合時，凸定位片50之第二定位凸塊54與凹定位片4〇之第 一疋位凹槽45相嵌合（如圖11所示），此時，凸定位片 之第—疋位凸塊55則洛在相對於凹定位片4〇之第二定位凹 槽46的位置（如圖12所示），由於前述的關係， 即第—定位凸塊54落入第—定位凹槽45中的高度扣除第二 與第三定位凸塊54、55的高度差後，小於第二定位凹槽46 的深度，故第二定位凹槽46的深度足以容許第三定位凸塊 乃相對落入其中，以讓第二定位凸塊54可與第一定位凹槽 45相嵌合’當開始打開上蓋9〇時，產生第—峰值扭力以使 第二定位凸塊54可脫離第一定位凹槽45。 請參閱圖9及圖13至15所示，當繼續開啟上蓋9〇時， 凸定位片50之第二定位凸塊54於凹定位片40之第二側面Referring to FIG. 9 to FIG. 12, when the upper cover 90 is closed relative to the base 91, the second positioning protrusion 54 of the convex positioning piece 50 is engaged with the first positioning groove 45 of the concave positioning piece 4 (eg Figure 11), at this time, the first positioning projection 55 of the convex positioning piece is at a position relative to the second positioning groove 46 of the concave positioning piece 4 (as shown in Fig. 12), due to the foregoing The relationship, that is, the height of the first positioning protrusion 54 falling into the first positioning groove 45 minus the height difference between the second and third positioning protrusions 54, 55 is smaller than the depth of the second positioning groove 46, so the second The depth of the positioning groove 46 is sufficient to allow the third positioning protrusion to fall relatively therein, so that the second positioning protrusion 54 can be engaged with the first positioning groove 45. When the upper cover 9 is opened, the first portion is generated. The peak torque is such that the second positioning projection 54 can be disengaged from the first positioning groove 45. Referring to FIG. 9 and FIG. 13 to FIG. 15, when the upper cover 9 is continuously opened, the second positioning protrusion 54 of the convex positioning piece 50 is on the second side of the concave positioning piece 40.
43上滑動，以產生轉動時的一般扭力，此時由於H2>H3，即 第一疋位凸塊54的高度大於第三定位凸塊55的高度，故第 三定位凸塊55遠離凹定位片40之第二側面43,亦無法與第 二定位凹槽46相嵌合。 請參閱圖9及圖丨6至圖18所示，當持續開啟上蓋9〇 至開啟角度為45度時，凸定位片50之第三定位凸塊55恰 與凹定位片40之第一定位凸塊47相頂抵，則使凸定位片/〇 相對被推頂遠離凹定位片 於Η|+Η3>Η2，即第—與第 40，以產生第二♦值扭力，此時由 三定位凸塊47、55的高度和大於 9 M400739 91底座The third positioning protrusion 55 is away from the concave positioning piece because the height of the first clamping protrusion 54 is greater than the height of the third positioning protrusion 55. The second side 43 of the 40 is also incapable of being engaged with the second positioning recess 46. Referring to FIG. 9 and FIG. 6 to FIG. 18 , when the upper cover 9 is continuously opened to an opening angle of 45 degrees, the third positioning protrusion 55 of the convex positioning piece 50 is just opposite to the first positioning convex of the concave positioning piece 40 . When the block 47 is abutted, the convex positioning piece/〇 is relatively pushed away from the concave positioning piece at Η|+Η3>Η2, that is, the first and the 40th, to generate the second ♦ value torsion, and at this time, the three positioning convex Height of blocks 47, 55 and greater than 9 M400739 91 base
