[0026] In this embodiment, the outer wall of the mounting plate 1 is fixedly connected to the base 15, one side of the mounting plate 1 is fixedly connected to the support plate 25, the top of the support plate 25 is fixedly connected to the motor 26, the output shaft of the motor 26 rotates through the support plate 25 and is fixedly connected to the first bevel gear 27, the first bevel gear 27 is meshedly connected to the second bevel gear 28, the second bevel gear 28 is fixedly connected to the bidirectional screw 3, and the base 15 is provided with a mounting groove 24 at the position of the second bevel gear 28.

[0029] Working principle: When using the device, the high-voltage DC line voltage divider can be placed on the mounting plate 1, between the two rubber pads 11, and then the motor 26 is started, the output shaft of the motor 26 will drive the first bevel gear 27 to rotate, the first bevel gear 27 will drive the second bevel gear 28 to rotate, the second bevel gear 28 will drive the bidirectional screw rod 3 to rotate, the bidirectional screw rod 3 will drive the two threaded sleeves 4 to move away from each other, the movement of the threaded sleeve 4 will drive the first square plate 5 to move, the first square plate 5 will drive the sleeve plate 6 to move, the sleeve plate 6 will drive the sliding rod 7 to move along the guide groove 13, and the sliding rod 7 will also drive the sliding When the block 8 moves, the slider 8 will drive the second slide rail 9 to move. When the sliding rod 7 moves in the inclined groove of the guide groove 13, the two second slide rails 9 will approach each other, and the two 9 will drive the two clamping plates 10 to approach each other. The two clamping plates 10 will drive the two rubber pads 11 to approach each other until they touch the high-voltage DC line divider. After the sliding rod 7 enters the straight groove of the guide groove 13, the high-voltage DC line divider can be clamped and fixed. When the high-voltage DC line divider is used outdoors, if the wind force is too strong, the motor 26 can continue to work to make the two threaded sleeves 4 continue to move away from each other. The movement of the threaded sleeve 4 will drive When the extrusion plate 14 moves, the extrusion plate 14 will drive the second square plate 16 to move, and the second square plate 16 will drive the second support plate 17 to move, and the two second support plates 17 will move away from each other. At the same time, when the two extrusion plates 14 move away from each other and contact the trapezoidal plate 18, the extrusion plate 14 will squeeze the trapezoidal plate 18, so that the trapezoidal plate 18 moves away from the second square plate 16. The movement of the trapezoidal plate 18 will drive the first support plate 12 to move, so that the first support plate 12 and the second support plate 17 move to increase the support range, thereby improving stability. When the first support plate 12 moves, it will also drive the limit rod 19 to move along the circular groove 22 to ensure that the first support plate 12 and the second support plate 17 are supported. One support plate 12 will not deviate when moving, and at the same time, the first support plate 12 will also pull the tension spring 20 to stretch the tension spring 20. After the wind force becomes smaller, the output shaft of the motor 26 is reversed, so that the two threaded sleeves 4 can be brought closer to each other, and the two second support plates 17 can be brought closer to each other, and the first support plate 12 can be moved closer to the base 15 to reduce the area occupied by the device. When the high-voltage DC line voltage divider needs to be removed, the sliding rod 7 is slid into the inclined groove of the guide groove 13 again and continues to move to move the two clamping plates 10 away from each other, and the rubber pads 11 will move away from each other, so that the clamping of the high-voltage DC line voltage divider can be released.
