In this embodiment, as shown in fig. 5, the charging plug is connected to the sensor, the sensor is connected to the cable, two second electrical contacts 115 are disposed on the bottom surface of the charging plug, two first electrical contacts 15 are disposed at corresponding positions on the base 4, the bottom surface of the charging plug is placed on the base 4, and the first electrical contacts 15 and the second electrical contacts 115 are conducted to form a loop for supplying power to the commodity.

In the present embodiment, as shown in fig. 12, the rotary shaft 1 is vertically installed in the base 4. The connected mode of pivot 1 and base 4 can be the joint or through screwed connection or adopt other detachable modes, the utility model discloses do not improve the mounting means of pivot 1.

Other embodiments in this example are the same as example 1.

It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall belong to the protection scope of the present invention.
