[0024] As attached Figure 1 To Attachment Figure 4 As shown:

[0025] Embodiment 1: An automatic power-off device for power production and operation failures, comprising a power-off body 1, the front and back of the power-off body 1 are both provided with power connection ports 2, the top of the power-off body 1 is respectively provided with a through port 5 and an adjustment slot 10, the inner side of the through port 5 is threadedly connected with a crimping assembly, the inner side of the adjustment slot 10 is movably connected with a switch frame 11, the top of the switch frame 11 is fixedly connected with a switch board 12, the bottom of the switch frame 11 is fixedly connected with a power connection board 1101, and the top of the power-off body 1 is respectively fixedly connected with a power socket 8 and a power switch 13 on both sides away from the adjustment slot 10;

[0026] The top of the power socket 8 is fixedly connected with a power fuse seat 9 , the bottom of the power fuse seat 9 is fixedly connected with a fuse plug plate 901 , and the inner side of the fuse plug plate 901 is fixedly connected with a fuse 902 .

[0027] As can be seen from the above, when a fault occurs in the power operation, the power switch 13 will be opened due to voltage overload, thereby closing the power board 1101. When the generated voltage exceeds the rated voltage, the fuse 902 on the power fuse holder 9 will melt, thereby disconnecting the power supply. At the same time, when the power switch 13 or the fuse 902 fails, only one of the power-off devices needs to be used to cut off the power.

[0028] Embodiment 2: The front of the power-off body 1 is fixedly connected to a power input socket 3 via the power port 2, the back of the power-off body 1 is fixedly connected to a power output socket 14 via the power port 2, the backs of the power input socket 3 and the power output socket 14 are both fixedly connected to a power-on piece 301, and the power input socket 3 is fixedly connected to the power-on socket 8 via the power-on piece 301.

[0029] As can be seen from the above, the power cord can be installed by inserting the power cord into the power inlet socket 3 and the power outlet socket 14 of the power port 2 respectively, and then rotating the adjusting screw 6, so that the adjusting screw 6 drives the pressing plate 4 to press the power cord.

[0030] Embodiment 3: The wire pressing assembly includes an adjusting screw 6 and a pressing plate 4. The adjusting screw 6 is threadedly connected to the inner side of the through opening 5, and the bottom end of the adjusting screw 6 is movably connected to the pressing plate 4.

[0031] As can be seen from the above, the power cord is respectively inserted into the power inlet socket 3 and the power outlet socket 14 of the power port 2, and then the adjusting screw 6 is rotated, and the adjusting screw 6 drives the pressing plate 4 to press the power cord to complete the installation.

[0032] Embodiment 4: A power transmission board 801 is fixedly connected to the bottom of the power socket 8, and the power transmission board 801 is made of copper material.

[0033] As can be seen from the above, the power transmission board 801 made of copper material can better transmit power, making the power-off device less likely to be corroded and damaged.

[0034] Embodiment 5: The fuse 902 is made of silver-copper alloy material, and the fuse 902 is a solid structure.

[0035] As can be seen from the above, the fuse 902 made of the silver-copper alloy material has a larger resistivity and a lower melting point, so that the fuse 902 can be melted more easily.

[0037] As can be seen from the above, the installation slot 7 makes it convenient for workers to install the power disconnecting device in the distribution box.

[0038] Working principle: When using the automatic power-off device for power production and operation failure, the staff inserts the power cord into the power inlet socket 3 and the power outlet socket 14 of the power connection port 2 respectively, and then rotates the adjusting screw 6, and the adjusting screw 6 drives the pressing plate 4 to press the power cord to install it. At this time, the power acts on the power socket 8 through the power-on piece 301 on the power inlet socket 3, and then acts on the power transmission board 801 through the power-on fuse seat 9, and the power will be transmitted to the power connection board 1101, and then the power is transmitted through the power-on piece 301 on the power outlet socket 14. The power is transmitted out. When the power operation fails, the power switch 13 will be opened due to voltage overload, thereby closing the power board 1101. When the generated voltage exceeds the rated voltage, the fuse 902 on the power fuse holder 9 will melt, thereby disconnecting the power supply. At the same time, when the power switch 13 or the fuse 902 fails, only one of the power-off devices needs to be used to cut off the power. In this way, the use process of the utility model is completed. The utility model has a simple structure and is safe and convenient to use.
