when pushing the key (411), the push rod (414) pushes the connecting rod (413) to rotate around the support (421), the connecting rod (413) pushes the locking block (412) to press the pressing elastic piece (415) until the locking block (412) is separated from the watch charging seat (5), and the locking assembly (41) is undefined;

when the key (411) is released, the elastic deformation of the pressing elastic piece (415) is recovered, the locking piece (412) drives the connecting rod (413) to reset, the locking piece (412) is recovered to be propped against the watch charging seat (5), and the locking assembly (41) is locked.

4. A combined charger according to claim 3, characterized in that the inner side of the integrated adapter box (4) is provided with a chute (422) for guiding the sliding of the locking block (412).

5. The combined charger according to claim 2, wherein a fixed pressing block (45) is fixedly arranged in the integrated switching box (4), a rotating shaft (51) hinged with the fixed pressing block (45) is integrally and fixedly arranged on the watch charging seat (5), and a torsion elastic piece (52) for assisting the turnover of the watch charging seat (5) relative to the mounting groove (40) is arranged at the end part of the rotating shaft (51).

6. The combined charger according to claim 2, characterized in that the integrated adapter box (4) is fixedly provided with a limit pressing block (47), one side of the limit pressing block (47) is fixedly provided with an elastic limit plate (48) and the other side is hinged with a charging adapter (6), and a limit protrusion (61) and a limit groove (481) are arranged between the elastic limit plate (48) and the charging adapter (6); when the charging adapter (6) rotates to be perpendicular to the elastic limiting plate (48), the limiting protrusion (61) is in concave-convex fit with the limiting groove (481).

7. The combined charger according to any one of claims 1 to 6, wherein at least one power output interface (492) is provided in the integrated adapter box (4), and the magnetic charging seat (3) is provided with an external power line (31) connected with one of the power output interfaces (492) in a plugging manner.

8. The combined charger according to claim 7, wherein a wire clamping groove (111) for fixing the external power wire (31) is formed in one side of the first mounting plate (1) close to the second mounting plate (2).

9. The combined charger according to any one of claims 1 to 6, wherein the magnetic charging stand (3) comprises a magnetic group (35) which is annularly distributed and provided with a limiting convex ring (351), a circular circuit board (33) which is fixedly provided with a coil and coaxially arranged on the limiting convex ring (351), and a flexible heat dissipation piece (34) which is arranged between the magnetic group (35) and the coil.

10. The combined charger according to claim 9, characterized in that the magnetic charging stand (3) further comprises a metal heat-dissipating shell (36) in contact with the flexible heat-dissipating member (34) and coaxially covering the outside of the magnetic group (35) and the circular circuit board (33).
