The invention discloses auxiliary shoe wearing equipment. When the auxiliary shoe wearing equipment is used, a knob rotates, by changing relative positions of a middle point of a pedal and a shoe hookcontact point, the shoe wearing equipment can be adjusted when the age of a user is increased or the footwear size of the user is changed due to other factors, and thus, the shoe wearing equipment can be always suitable for the user. By a spring arranged on the lower portion of the pedal, the front and the rear of the pedal can swing at an angle of 30 degrees, when the auxiliary shoe wearing equipment is used, feedback and springback to the user are implemented, and thus, the user can control force generated during shoe wearing and shoe taking-off well.

The invention relates to an electrode and a molten salt electrolysis device. The electrode comprises a rod-shaped part and a supporting part, wherein one end of the rod-shaped part is fixedly connected with the supporting part; the rod-shaped part is positioned in an electrolytic bath while the supporting part is positioned at the outer side of the electrolytic bath and used for sealing an opening of the electrolytic bath during an electrolytic process; and the supporting part is electrically connected with an additional power supply. The electrode is very short, the electrode does not need to pass through the top end of an upper cavity to come into contact with the air in the process that the electrode enters or exits from the electrolytic bath, so that the lifting of the electrode in the upper cavity is realized. Thus, the electrode cannot be corroded, namely, the service life of the electrode is prolonged. The invention provides the molten salt electrolysis device which comprises the electrode and a wiring part. The supporting part is connected with the additional power supply through the wiring part, so that the effects of easy separation and proper movements between the additional power supply and the electrode are realized. According to the molten salt electrolysis device, the lifting of the electrode is realized through a sling structure arranged in a sealing cavity, so that the hidden danger that the air is led in due to the vacuum damage possibly caused by an electrode moving channel is eliminated.

The invention discloses a smart electricity meter and an electricity theft prevention system. In the smart electricity meter, an electricity collection module is directly connected to the power supply output end of the electricity meter, and is used to collect the electricity consumption of all household appliances. The judgment module judges whether the electricity consumption measured by the watt-hour meter is consistent with the electricity consumption collected by the electricity consumption acquisition module. When the control module sends a control command to the power supply network center, the power supply network center cuts off the power supply to the watt-hour meter, thereby making the watt-hour meter stop supplying power to the household appliances. In the above manner, the present invention can effectively prevent the behavior of stealing electricity and reduce the hidden danger of electricity consumption.
