In this embodiment, the specific angular position is the first angular position, and the first locating structure 26 and the second locating structure 521a which are concave and convex with each other are used to enable the shaft member 3 to be positioned at the first angular position. Additional positioning torque is obtained, thereby making the cover body 300 less likely to be opened due to misoperation or other external forces when the cover body 300 is closed relative to the main body 200, and can also improve the operating feel during the cover closing process. It should be noted that, in other implementation aspects, the specific angular position may also be the second angular position or other angular positions between the first angular position and the second angular position, and the specific angular position The number can also be more than two. In terms of practical application, the number of the specific angular positions and their actual angular positions can be determined according to the positions and numbers of the positioning bumps 521b and the positioning grooves 261. Therefore, this embodiment is not limited.

It is worth mentioning that, because the torsion unit 5 used to provide the positioning torque is uniaxially arranged only on the shaft member 3, not on other components (such as the co-moving gear) at the same time. above), so it is easier and more precise to design or adjust the positioning torque.

In summary, the present invention utilizes the sliding seat 2 of the shaft member 3 slidably disposed on the base 1 and rotatably passed through it, the rack 41 and the driving gear of the linkage unit 4 . 42 and the driven gear 43, when the shaft member 3 is rotated from the first angular position to the second angular position, the cover body 300 disposed on the shaft member 3 can slide from the first position to the The sliding seat 2 in the second position slides along the front-rear direction D1 (the first direction), so the hinge 100 can meet the special design requirements of synchronous sliding when the electronic product is rotated.
