The invention discloses an intelligent switch testing device and method. The intelligent switch testing device and method can improve the safety of testing operation and optimize the testing efficiency. The intelligent switch testing device comprises a case and a panel covering one side of the case. The panel comprises at least one test position for accommodating an intelligent switch. A probe isarranged in each test position, and the probe comprises a power supply probe corresponding to a power supply wiring end of the intelligent switch and an on-off key probe corresponding to an on-off keywiring end of the intelligent switch. A circuit module is arranged in the case. Each power supply probe is connected with an external power supply through the circuit module, and each on-off key probe is connected with the external power supply through the circuit module after the on-off key probe is in series connection with a state indicating lamp. Therefore the intelligent switch is powered onwhen placed in the test position, the state indicating lamp is lightened or extinguished according to the state of the on-off key of the intelligent switch, and the state indicating lamp is displayedon the panel.

The invention provides an automatic power-on and power-off electric hair drier bracket, which comprises an electric hair drier, a wall hanging plate, an electric hair drier bracket, a bracket groove,a first reset spring, a spring fixing shell, a first push rod, a first positioning piece, a plug board base, a static contact set, a conducting sheet set, a plug clamping sheet, a wiring terminal, a second positioning rod, a second push rod, a second reset spring, a moving contact set and a plug board shell. According to the invention, by arranging a wall hanging plate and an electric hair drier bracket arranged on a wall surface, when an electric hair drier is taken up from the electric hair drier bracket, the electric hair drier bracket can be automatically bounced, and a moving contact setand a static contact set are driven by a linkage mechanism to be automatically connected, so that a plug is electrified; and when the electric hair drier is placed on the electric hair drier bracket,the electric hair drier bracket descends and resets under the gravity action of the electric hair drier, and the moving contact set and the static contact set are automatically separated through the linkage mechanism, so that the plug is automatically powered off, the plug can be automatically powered on and off without plugging and unplugging the plug, and the safety is improved while the electric hair drier is convenient to use.

The invention discloses a multi-insert smart socket, comprising a socket cover, a conductive sheet and a socket base; the socket cover and the socket base are detachably connected, and the conductive sheet is arranged between the socket cover and the socket base; the socket cover is provided with crosses distributed in a nine-square grid Through holes; nine cross holes are arranged on the conductive sheet corresponding to the cross holes. The conductive sheet includes two one-hole conducting sheets, two two-hole conducting sheets and three-hole conducting sheets. The three-hole conducting sheets are along the opposite corners of the socket cover. The wires are arranged obliquely under the socket cover, and two one-hole conducting sheets, two two-hole conducting sheets and three-hole conducting sheets are arranged in parallel; two one-hole conducting sheets, two two-hole conducting sheets and three-hole conducting sheets are respectively fixed by The column is fixedly connected on the socket base; two one-hole conducting sheets and three-hole conducting sheets are connected in series, and two two-hole conducting sheets are connected in series. Since the cross jacks correspond to the cross holes, the distribution and connection of the conductive sheets can be simultaneously connected to a plurality of electrical equipment, and the use is convenient.

The invention discloses an electric actuator. The electric actuator comprises a shell (1), an upper box plate (2), a support (3) , a direct-current brushless motor (4), an upper cover (5), a wiring cover (6), a circuit plate (7), a gear train (8), a main shaft (9), a valve rod connecting part (10), an electromagnetic coil (11), a manual clutch (12) and a manual wrench (13). According to the electric actuator, a secondary gear in the gear train is used as a driving gear and a manual gear as well, so that structure design of the electric actuator is greatly simplified, and operation is simple; the electromagnetic coil sleeves the outer edge of a boss hole, so that automatic power-off during manual operation and automatic power-on after the manual operation is finished are achieved, and the manual operation is simplified; overload protection of the secondary gear and other components in the electric actuator can be realized through design of the manual clutch; and the electric actuator has the advantages of being simple in structure, reasonable in design, convenient to use, low in manufacturing cost and the like.
