'" Gekou 圃 (the diagram of =0, the upper cover 3 2 relative to the body 3 i self-closing to _, state, the operation of a plot of a moment A and a weight of 6, using 牯, is The two-consolidation plate 43 of the base 40 is fixed to the body 31, and the net cover, and the upper cover 32 is assembled to the two sets of the base plates 83 of the connecting seat 8〇. At this time, the second secret member 60 is applied to the inner sliding plate. The elastic thrust of the seat 5 形成 forms the counterclockwise elastic moment A with respect to the first insertion 〇 1 , and the clockwise heavy moment B is formed by the upper cover ( 2 ) of the upper cover ( 2 ) The:: moment A and the heavy moment β will be different according to the position of the above-mentioned components, and the inner chamber of the base 4 is detailed as follows: , = the upper cover 32 is in a twist state relative to the body 31, and the moment B is greater than the elastic moment A, so the knife is very close to the upper/lower W position in the closed position, and at this time " 2 is in contact with the The bottom portion (10) of the track 541, 1289110, the two elastic members 60 are in a compressed state. As shown in Figures 3, 8, and 12, when the operator applies the force to open the upper cover 32, the driver The pedestal 80, the pedestal 7 〇 , the third pivot 1 〇 3 , the second pivot 102 , and the outer slider 90 are pivoted by the first pivot 1 〇 1 and the outer slide is slid The contact surface 92 of the block 90 moves from the bottom portion 542 of the trace surface 541 toward the projection 543. When the upper cover is increased from 0 degrees to about 17 degrees with respect to the body 31, the elastic moment A and The weight moment 6 will produce an intersection point, that is, the two are equal such that the upper cover 32 can automatically obtain a position for balanced positioning. As the angle of the upper cover 32 relative to the body 31 gradually increases, the elastic moment A continues to be slightly The state greater than the heavy moment b is offset by the friction between the obstruction surface 541 and the contact surface 92, so that the upper cover 32 can be positioned at any position without going up. As shown in FIGS. 9 and 12, when the upper cover 32 is continuously opened to be about 60 degrees with respect to the body 31, the contact surface 92 is moved to the projection 543 of the obstruction surface 541, and at the same time The inner slide 50 is moved in the opposite direction of the abutting plate 442 by the elastic force of the two elastic members 60 so that the obstructing surface 541 and the contact surface 92 are indeed in contact with each other. During the moving process, the inner sliding seat 5〇 can be smoothly moved by the combination of the two guiding grooves 511 and the first pivot shaft 1〇1, at which time the spring moment A is slightly larger than the weight. The state of the moment B, but because the torque difference between the two can be offset by the aforementioned frictional force, the upper cover can still obtain balanced positioning, and does not suddenly fall down when interfered by external force. As shown in Fig. 10 and 12. When the upper cover 32 is continuously opened to increase relative to the body 31 to 9 degrees, the contact surface 92 is moved from the protruding portion 543 of the track surface 12 1289110 1 to the top portion 544 when the upper cover is When the opening is 32 to the position of 9 degrees, the top plate 41 of the base 4G can be prevented by the second connecting plate 82 of the connecting seat 80 to prevent the upper cover 32 from being turned backwards. In the state of FIG. The elastic member 6〇 has the smallest amount of extrusion and is also at an angle. ^ Also, it should be noted that the second pivot 1〇3 is located at the second hole end 752 of the arcuate hole 75 when the upper cover 32 is closed to the open state.
