Example 2:

the difference from the embodiment 1 is that:

as shown in fig. 5, the charging interface 704 may be a charging contact plate made of ferromagnetic material (e.g. metal iron), the charging head 202 includes a conductive spring 9, one end of the conductive spring 9 contacts with the charging contact plate, and the other end of the conductive spring may be electrically connected to an external power supply or an internal lithium battery 92, so as to charge the sub-table 7.

Further, the charging head 202 further includes a permanent magnetic tube 91 coaxially disposed with the conductive spring 9, and the permanent magnetic tube 91 can provide a stable electromagnetic field, so that the charging contact plate is abutted against one end of the conductive spring 9 under the action of the electromagnetic field to maintain an electrical connection state during charging.

When the auxiliary worktable 7 needs to be moved outwards, force is applied only through the hand of a human body so as to overcome the suction force of the permanent magnet tube 91 on the charging contact plate and move outwards.

Further, a lithium battery 92 is disposed inside the permanent magnet tube 91, and a solenoid 93 is disposed between the lithium battery 92 and the permanent magnet tube 91. One side of the charging contact plate facing the permanent magnetic tube 91 is provided with a movable contact 94, one end of the permanent magnetic tube 91 facing the movable contact 94 is provided with a static contact 95 capable of being matched with the movable contact 94, and the static contact 95 is electrically connected with the anode of the lithium battery 92. One side of the moving contact 94 is electrically connected to the solenoid 93 through the conductive spring 9, and one end of the solenoid 93 is electrically connected to the battery cathode of the lithium battery 92. When the charging contact plate is in contact with the conductive spring 9, the moving contact 94 is still spaced from the stationary contact 95.

In the above, the conductive spring 9 has two cases:

when the conductive spring 9 is connected with an external power supply, the conductive spring 9 plays a role as a charging medium of the secondary workbench 7 to realize the charging of the secondary workbench 7.

Secondly, when the conductive spring 9 is not connected with an external power supply, the battery in the lithium battery 92 does not work because the moving contact 94 and the static contact 95 still have an interval. Only under the action of external pressure, the auxiliary worktable 7 is driven to move towards the direction extruded by the conductive spring 9 by applying force through the hand of a human body, after the conductive spring 9 is compressed for a certain distance, the static contact 95 is connected with the movable contact 94, and at the moment, an electric loop is formed by the battery, the solenoid 93, the supporting spring, the movable contact 94 and the static contact 95. Causing the solenoid 93 to energize and generate an electromagnetic field that cancels with the permanent magnet tube 91. At this time, after the hands are released again, the conductive spring 9 gives a reverse elastic force to the sub-table 7, so that the sub-table 7 is removed from the cover 2 by the reverse elastic force.
