In this embodiment, the outer diameter of the actuator 1 is slightly larger than the outer diameter of the coupler 2, and a groove 10 for accommodating the coupler 2 is provided at the lower end of the actuator 1, and at least a portion of the coupler 2 is operably accommodated inside the groove 10.

[0064] In a preferred embodiment, the actuator 1 is a hanging steamer, which includes a shell 50 with a steam outlet, a water tank 51 arranged inside the shell 50, a water pump 52 connected to the water tank 51, a heater 53 arranged between the water tank 51 and the steam outlet, and a steam switch 54 for controlling the water pump 52 and the heater 53.

[0065] Further, as a preferred embodiment, the actuator 1 has at least one conductive column 11, the coupling device 2 has at least one spring 21, and the conductive column 11 matches the spring 21. Preferably, the conductive column 11 protrudes from the groove 10.

[0067] Further, as a preferred embodiment, at least one spring sheet 21 includes an L spring sheet, a ground spring sheet and an N spring sheet; at least one conductive column 11 includes an L column, a ground column and an N column.

[0068] Further, as a preferred embodiment, the locking device includes: a first locking device for locking or separating the actuator 1 and the coupler 2 , and a second locking device for locking or separating the coupler 2 and the base 3 .

[0071] Specifically, the coupler lock 42 has a first inclined surface 61 set upward and a second plane 62 set downward. The setting of the first inclined surface 61 enables the coupler lock 42 to automatically retract when the actuator 1 moves downward due to the action of the inner wall of the groove 10, and when the actuator buckle hole 41 passes through the coupler lock 42, the coupler lock 42 can automatically extend to be inserted into the actuator buckle hole 41; the setting of the second plane 62 prevents the actuator 1 from moving directly upward without other external force to cause the coupler lock 42 to retract.

[0072] Further, as a preferred embodiment, the first locking device includes: a first elastic member 43, the first elastic member 43 is arranged in the coupler 2, and the first elastic member 43 constantly provides a force acting on the coupler lock buckle 42 and along the first direction toward the actuator buckle hole 41. Preferably, the first elastic member 43 is a spring.

[0075] Further, as a preferred embodiment, the first locking device further comprises: a coupler lock bar 44, the coupler lock bar 44 being movable in a second direction intersecting the first direction;

[0076] In this embodiment, the second direction is Fig. 9 , Fig.10 The first direction is substantially vertical, that is, a direction perpendicular to the axial direction of the first elastic member 43. In other embodiments, the first direction and the second direction may not be perpendicular.

[0078] Specifically, the coupler lock 42 has a third inclined surface 63, and the upper end of the coupler lock rod 44 has a fourth inclined surface 64. The third inclined surface 63 and the fourth inclined surface 64 are offset from each other, so that the movement of the coupler lock rod 44 in the second direction forms a component force in the first direction, thereby driving the coupler lock 42 to move along the first direction.

[0079] Further, as a preferred embodiment, the coupler lock rod 44 is operable to provide a force acting on the coupler lock 42 and away from the actuator buckle hole 41 along a first direction.

In other embodiments, the third direction and the first direction can be in the same vertical plane and the third direction and the first direction are not parallel, or the third direction and the first line of defense are in different vertical planes and the third direction and the first direction are parallel. In another embodiment, the third direction and the first direction can be in different vertical planes and the third direction and the first direction are not parallel. In other words, the third direction and the first direction are determined by the specific shape of the coupler lock rod 44 and the inclination of the upper end face and the lower end face.

[0083] Further, as a preferred embodiment, the second locking device includes: a second elastic member 47, the second elastic member 47 is arranged on the base 3, and the second elastic member 47 constantly provides a force acting on the base lock 46 and away from the coupler buckle hole 45 along the third direction. Preferably, the second elastic member 47 is a spring.

[0084] Specifically, the second elastic member 47 provides Fig. 9 The force from left to right in the middle makes the base lock 46 keep the trend of being separated from the coupler buckle hole 45. And the force that keeps the base lock 46 to insert the coupler buckle hole 46 is provided by the following lock button 48.

[0085] Further, as a preferred embodiment, the lower end of the coupler locking rod 44 cooperates with the base locking rod 46 through an inclined surface so that the movement of the coupler locking rod 44 in the opposite direction of the second direction (i.e., the downward direction) is converted into the movement of the base locking rod 46 in the third direction.

The fifth inclined surface 65 and the sixth inclined surface 66 are offset from each other, so that the movement of the coupler lock rod 44 in the second direction forms a component force in the third direction, or the movement of the base lock 46 in the third direction forms a separation in the second direction, so that the coupler lock rod 44 drives the base lock 46 to move along the third direction, or the base lock 46 causes the coupler lock rod 44 to move along the second direction.

[0087] Further, as a preferred embodiment, the coupler lock lever 44 is operable to provide a force acting on the base lock 46 and away from the coupler lock hole 45 along the third direction.

[0088] Further, as a preferred embodiment, the second locking device also includes: a lock button 48, which is arranged on the base 3, and the lock button 48 drives the base lock 46 to move along the third direction.
