[0029] The first lock block 41 and the second lock block 42 are respectively provided with independent first lock block supporting elastic components 61 and second lock block supporting elastic components 62, which can be springs. The supporting elastic components 61 and 62 of the first lock block 41 and the second lock block 42 are respectively used to keep the first lock block 41 and the second lock block 42 in a locking state, that is, after being rotated to an angle of locking cooperation with the cooperation part, the state is kept without being reversed and loosened. The independent first lock block supporting elastic components 61 and the second lock block supporting elastic components 62 can independently reset the rotation and keep the locking of the first lock block 41 and the second lock block 42, and can make the locking parts 410 and 420 on the first lock block and the second lock block adopt an eccentric circle relative to the rotation axis, so that the locking effect is good and the precision requirement for locking cooperation is low.
[0030] The button is provided with an unlocking part 30 for controlling the state of the first lock block 41 and the second lock block 42. The sliding hinge is further provided with a reset elastic component of the unlocking part 30, which can be a spring 63.
[0031] The first lock block 41 and the second lock block 42 are oppositely arranged, and the unlocking part 30 is located between the first lock block 41 and the second lock block 42. The movement direction of the unlocking part 30 is perpendicular to the sliding direction, and the unlocking part 30 is in the shape of a conical frustum. Cam surfaces 43 cooperating with the unlocking part 30 are also arranged on the first lock block 41 and the second lock block 42, so as to improve the smoothness of pressing operation and the sensitivity adjustment of unlocking action.
[0032] The lower back surfaces of the first lock block 41 and the second lock block 42 cooperate with the supporting elastic components 61 and 62, and the unlocking part 30 is located between the front surfaces of the lower parts of the first lock block 41 and the second lock block 42.
[0033] The first lock block 41 is arranged at both ends of the rotation axis 411, the second lock block 42 is arranged at both ends of the rotation axis 421, and the button 3 is arranged at the left and right sides of the second connecting body 2.

[0035] The sliding hinge also includes a connecting block 5. A sliding guide groove 11 for the connecting block 5 is provided on the first connecting body 1. The second connecting body 2 is located on the front side 10 of the first connecting body 1. The sliding guide groove 11 has a T-shaped cross-section. The connecting block 5 is located within the sliding guide groove 11 and is connected to the second connecting body 2, for example, by screws. A stop block 7 is provided at the opening of the sliding guide groove 11.
[0036] When button 3 is pressed, and the unlocking component 30 pushes the two locking blocks away from the mating part (the front side 10), the second connecting body can be moved back and forth as needed. Figure 6 (in the left and right directions), after releasing button 3, under the action of springs 61 and 62, the first locking block 41 and the second locking block 42 rotate to engage with the mating part (front 10) and are in a locked state. At this time, Figure 5 For example, in the leftward movement direction, the first locking block 41 on the left side tends to rotate counterclockwise, and is locked by the cooperation of the eccentric circular locking part 410 and the mating part (which has a self-tightening function). In the rightward movement direction, the second locking block 42 on the right side tends to rotate clockwise, and is locked by the cooperation of the eccentric circular locking part 420 and the mating part (which has a self-tightening function).
[0037] The operating component can also be a sliding operating block that drives the unlocking component to move back and forth, thereby acting on the first locking block 41 and the second locking block 42 respectively.
