wherein the press lock catch comprises a lock case, which comprises an assembly cavity in which the snap tab is rotatably assembled, wherein when the snap tab is rotated in the assembly cavity to a first position in a first direction, the hook is snapped into the snap tab; when the snap tab is rotated in the assembly cavity to a second position in a second direction, the hook is disengaged from the snap tab; and the first direction and the second direction are opposite;
wherein the press lock catch further comprises a fixed seat, a compression torsional spring, and a lock knob, both ends of the compression torsional spring are respectively fixed to the fixed seat and the lock knob, and the fixed seat, the compression torsional spring, and the lock knob are respectively accommodated in an accommodation cavity of the snap tab; and wherein the compression torsional spring is capable of driving the lock knob and the snap tab to rotate together relative to the fixed seat between the first position and the second position;
wherein at the first position, the lock knob and the lock case are locked with each other, the snap tab cannot rotate; and wherein the lock knob is configured to be released from interlocking thereof with the lock case by an axial inward sliding of the lock knob so that the released lock knob further rotates the snap tab to the second position.
