The driving mechanism is provided with a locking mechanism that responds to external triggering to lock the driving mechanism at the first extreme position or unlock the driving mechanism at the second extreme position. The elastic retaining mechanism includes a drive member (6) that is slidably disposed in the cup lid body (1) and connected to the latch (5), an abutment member (7) disposed at the end of the drive member (6) away from the latch (5), an abutment member (8) disposed on the cup lid body (1), and an elastic member (9) disposed between the abutment member (7) and the abutment member (8) to drive the drive member (6) to drive the latch (5) to engage with the latch tongue (4); The driving mechanism is a pressing part (13) connected to the side of the abutment (7) away from the driving part (6) and exposed on the outside of the cup lid body (1); The side wall of the cup lid body (1) is provided with a sliding hole (14) for the pressing member (13) to slide along the direction of movement of the driving member (6); The locking mechanism includes a sliding component for the pressing member (13) to slide longitudinally on the abutment member (7) and a stepped surface (15) opened at the bottom of the sliding hole (14) for the pressing member (13) to abut against the side of the abutment member (7); when the pressing member (13) slides down to the kick surface (16) abutting against the stepped surface (15), the locking mechanism is in the first extreme position; when the pressing member (13) slides up to the kick surface (16) disengaging from the stepped surface (15), the locking mechanism is in the second extreme position.

2. A spring-loaded cup lid with a rear button locking function according to claim 1, characterized in that: The elastic element (9) is a compression spring, with its two ends pressing against the opposite surfaces of the abutting element (7) and the abutting element (8).

3. A spring-loaded cup lid with a rear button locking function according to claim 1, characterized in that: The cup lid body (1) has a cavity (10) for the movement of the driving component (6). Guide blocks (11) are provided on the upper and lower sides of the cavity (10). Guide grooves (12) that slide and engage with the guide blocks (11) are provided on the upper and lower sides of the driving component (6).

4. A spring-loaded cup lid with a rear button locking function according to claim 1, characterized in that: The sliding assembly includes two sliding grooves (17) formed on the abutment (7) and two sliders (18) disposed on the pressing member (13) and respectively longitudinally sliding and connected in the two sliding grooves (17).

5. A spring-loaded cup lid with a rear button locking function according to claim 4, characterized in that: The slider (18) is provided with positioning protrusions (19), and the side wall of the sliding groove (17) is provided with an upper positioning groove (20) and a lower positioning groove (21) from top to bottom so that the positioning protrusions (19) can be elastically engaged in the second limit position and the first limit position respectively.

6. A spring-loaded cup lid with a rear button locking function according to claim 4, characterized in that: The pressing part (13) is provided with two positioning rods (22) that are respectively movably inserted into two sliding grooves (17). The positioning rods (22) are provided with positioning buckles (23) that are fastened to the side of the abutment (7) away from the pressing part (13) to prevent the positioning rods (22) from disengaging from the sliding grooves (17).
