The clamping groove 13 is used to define the driving machine to increase the first and second wear resistance effects. -, / holes 11, 12 and the interlocking mechanism 2 adjacent to the younger brother shaft holes 11, 12 and the first and second 201249309 shafts 21, 22 adjacent to the adjacent faces are fixed with a wear ring 14, respectively The periphery of the ring 14 protrudes from the latch 14i so as to be inserted around the first and second lower shaft holes 12, 12, and the groove 15 is 'in the pair of wear rings 14 disposed around the lower positioning groove 13 An upper arm and a lower end of the lower positioning groove 13 respectively extend with an arm Μ with a blocking piece 143 to avoid the upper and lower ends of the groove 13 and the lower end of the slab 2, and the casting 211 repeatedly impacts the white 4: solid direction Extending a bottom plate 16 , the bottom plate 16 has a rear end longitudinally, and the bottom plate 16 has a plurality of holes (due to the projection: angle relationship is not included) so as to screw the base to the bottom wall of the back cover 52 II;: 3 === at least one side. Each of the first and second lower shaft pins 231 and 232 are respectively pivoted to the base, and the first earth end two and the second upper shaft pins 233 and 234 are respectively pivoted on the first end of the 24-axis end. The second rod holes 241, 2 are similar to the shaft holes 31 above the shaft socket 3, so that the shaft rods 21, 22, 2^ are added = 1 'the base 1 is opposite to the left and right sides of the linkage pin 231 The free end of ~234 is barely f. Each of the shafts 231 to 234 does not cause the axial direction = 36 ‘column to make the respective shaft pin holes 241 and 242. The first-lower shaft holes 11, 12 and the first and second limitations 2 "axis = lengths 21, 22 have different lengths, for example, but not a shaft 21, a second shaft 22, and a base jj. Thus, the first non-parallel four-bar linkage mechanism. In this case, the shaft-shaft 24 essentially forms a rear-loading shaft 3 that moves upward; when the outer chain structure is opened, it can be 201249309. In addition, the lower-aligning shaft 21 extends toward the lower positioning groove 13 The axis ^ is, for example, but not touched by the first _ 13 β 榫 211 ', the lower positioning 榫 211 疋 position groove 34, and the upper positioning 榫 244 is accommodated 疋 = 244 and - the axis ^ 3 relative to the The angle of rotation of the triaxial rod 24. (3) The inside is used to define the second one. The linkage mechanism 2 and the temple are spring-loaded so that the rear guiding mechanism 4^丨丨#1 has a different component %, for example, the longitudinal displacement of the elastic wall 421. = ^ 弹 引 引 ^ can be along the guiding member 42 to guide the two between the two lugs 17: pin 171: j on the pedestal 1 front section of the top surface of the 24th rod hole 241 帛 the other end is connected The first upper shaft pin 233 of the two third shafts; wherein 哕坌, 233 is sleeved between the two third shafts 24, and the second shaft is further sleeved with one end of the connecting piece 27, and the first The shaft core 26 moves to form an energy storage or release energy. The rotation of the connecting piece 27 is the second rod hole of the two third shafts 24: the f-pin 234 is sleeved - the second collar 28 is equal to the base 1 and is now The width of the second shaft 28 is equal to the total width of the two first collar brackets plus the connecting piece 27. The second shaft-shaft socket 3 is coupled to the bottom surface of the top wall of a front cover 51, which in turn is the upper shaft hole 31. In addition, the third upper shaft pin 23 has a hole secret and is disposed on the upper shaft hole 31 so as to pass the shaft joint 3 (4) to the second structure. Wherein, in order to increase the aforementioned upper shaft hole 31 and the linkage motor = the movement 3 i, the upper shaft hole 31 and the abutment surface of the third shaft 24 are fixed - the wear ring 3 ^ the wear ring 32 peripherally protrudes - the card 321 so as to be inserted into the upper sleeve hole ^. In addition, the axial periphery of the shaft socket 3 defines a groove circumference = and the positioning groove 244 of the third storage tube rear end is accommodated in the upper positioning groove=34. Further, the top surface of the shaft base 3 extends laterally by a top plate %, and the top plate 35 is longitudinally disposed downwardly from the guide member 41. Wherein, the top surface of the top plate 35 is plucked by a plurality of holes, so that the shaft socket 3 is locked to the bottom surface of the top wall of the front cover 51 by screws. The guiding mechanism 4 is composed of a guiding member 41 and a fixing member 42. The guiding member 41 is disposed parallel to and adjacent to the guiding wall 421 of the fixing member 42. For example, the member 41 can be body-mounted or separately disposed on the shaft. a side of the top plate 35 of the socket 3, and fixed to the side of the bottom plate 16 of the base, and the fixing member 4 is adjacent to the guiding member 41, so that the guiding The piece 41 and the fixture are formed in an adjacent arrangement. In order to reduce the holding of the guiding member 41 and the guiding wall 421, the bottom edge of the guiding member 41 has a raised end surface 411 surface 411 or the roller 412 can be rotated along with the guiding member. The guiding wall 421 is longitudinally displaced, and the guiding member μ is moved outwardly to the second side, and the shaft connecting seat 3 also drives the non-parallel four-bar linkage mechanism formed by the first kilogram to generate linkage. . For example, A丨Ξ installs the Hi-key structure on an electronic product, and the front cover 51 and the back cover computer have a casing 5'. The casing is composed of a motherboard, a hard disk drive, and a crystal display module. The pedestal 1 and the shaft pedestal 3 are respectively skirted; and in the present case, the pair of hinge structures and the top surface of the bottom wall are such that the bottom surface of the top wall of the rear ends of the front and back covers 51, 52 is as shown in FIG. .
