The displacement cam member forms a second cam surface toward the surface of the first cam surface 513. The first cam surface 513 corresponds to the second cam surface 522, the first cam surface 513 and the second cam. The surface 522 can be matched and can be relatively misaligned. When the rotating cam member 51 rotates relative to the displacement cam member 52, the cam-cam surface 513 and the second cam surface 522 are misaligned to push the rotating cam member 52 relative to the rotation. The cam member 51 is laterally displaced. The second elastic device (9) is sleeved between the shaft member 1 and the fixing member 15 of the shaft member 10. The shackle can switch between the first hunger and the second hunger. When the first body and the second body (not shown) are relatively closed, the pivot_ is located at the first position, and the first elastic means 31 is contracted. The second elastic means 6G is elastically released. At this time, the positioning portion 412 of the positioning member 41 does not protrude into the limiting slot of the base body 2, and the protruding portion of the pushing member 40 is like the rotating member 43. The member 42 forms a misalignment with the rotating member 43, and the pushing of the first elastic device & 9 201238449 J / linkage 42 forms a refraction. The rotating cam member 51 forms an anastomosis corresponding to the displacement cam member 52, so that the second elastic means 60 can be elastically released. Referring to Figures 8 through 13, a schematic diagram of the pivoting of the hinge of the present invention to the second position is shown. When the hinge is rotated to be in the second position, the seat body 2 is rotated by a predetermined angle of about 26G to 27G degrees with respect to the shaft member 1G, and the rotating cam member 51 is rotated by the rotation of the seat body 2〇. The rotating cam member η is rotated relative to the displacement cam member 52. The first cam of the rotating cam member 51 and the second cam surface 522 of the displacement cam member 52 are dislocated, and the first elastic device 60 is pressed to form an elastic force. Compressed, the hinge forms a positioning stop. The positioning portion 412 extends into the limiting slot 224. When the limiting slot 224 of the base 2G rotates, the limiting slot 224 rotates the positioning portion of the positioning member 41, and the positioning portion 412 simultaneously pushes the second limiting position. The portion 423 is rotated to enable the linking member 42 to rotate relative to the rotating member 43. The convex portion 424 of the linking member 42 forms an anastomosis corresponding to the concave portion 432 of the rotating member 43. At this time, the first elastic means 31 is elastically released to press the positioning member 41, the linking member 42, and the rotating member 43. The hinge is formed by the first cam surface 513 corresponding to the second cam surface 2, and the convex portion 424 of the linking member 42 forms an anastomosis with the concave portion 432 of the rotating member 43. After the seat body 2 is positioned with the shaft member 10 and cannot rotate relative to each other, and the convex portion 424 is matched with the y portion 432, the convex portion 424 cannot be directly reversed from the concave portion 432 because the convex portion 424 is When the concave portion 432 is directly reversed, the convex portion 201238449 portion 424 is blocked by the concave portion 432 by a right angle surface. At this time, the first body coupled to the shaft member 10 and the second body coupled to the base body 2G can stand on the table top to form a triangle, and the first body and the second body with the opening facing downward can be directly placed on the table top. Provides user operations at opposite ends. FIG. 14 to FIG. 10 are schematic diagrams showing that the hinge of the present invention is changed from the second position to the third position. The hinge is located at the third position, and the seat body 20 is continuously rotated forward by about 25 degrees to 35 degrees, so that the linkage member is continuously rotated forward by the inclined surface 4241, so that the linkage member is detached from the rotating member 43. The locking position, at this time, the linking member 42 can be driven by the seat body 20=the limiting slot 224 to drive the positioning portion 412 of the positioning member 41, and the linking member 42 is quickly rotated from the third position to the first position relative to the rotating member 43. The positioner forms an automatic reset. The concave portion 432 of the third portion 43 of the linking member 42 is dislocated, and the cam surface 513 of the rotating cam member 51 is dislocated with the second cam surface 522 of the displacement cam member 52. The elastic dream device 60 is also subject to elasticity.

The hinge is defined by the second body of the electronic product 1 and the main body 1G1.
