By setting the U-shaped block 23, when the composite switch device is installed inside a distribution box or other equipment, the circuit is connected to the top of the body 1 After the connection of the terminal block 4 is completed, the sliding rod 22 can be pushed to slide up and down on the inner wall of the groove rod 21 to adjust the height position of the sliding rod 22, and then the threaded ring 28 is rotated to make the threaded ring 28 move on the outer surface of the screw rod 27 to press one side against the side of the groove rod 21 to fix the position of the sliding rod 22, and then the elastic metal sheet 24 inside the U-shaped block 23 is broken open, and the line is clamped between the elastic metal sheet 24 and the inner wall of the U-shaped block 23, and the elastic metal sheet 24 is loosened and pressed against the surface of the line to arrange and fix the line, and then the bolt 25 is rotated to make the bolt 25 move downward and press on the top of the elastic metal sheet 24, so as to further fix the position of the line inside the U-shaped block 23. When the line needs to be repaired, the bolt 25 is rotated away from the elastic metal sheet 24 and then the elastic metal sheet 24 is broken open to take out the line, thereby improving the convenience and flexibility when using the composite switch device.

[0029] Reference Figures 2-4As shown, in this embodiment: Two inclined rods 26 are fixedly connected to the bottom end of the U-shaped block 23. One end of the two inclined rods 26 away from the U-shaped block 23 is fixedly connected to one side of the sliding rod 22.

The two springs 34 will return to their original state and push the two card blocks 35 to move outward and insert them into the slot 32 respectively. Install the positioning device 2 at the top of the device body 1, and then push the sliding rod 22 to slide up and down on the inner wall of the slot rod 21 to adjust the height position of the sliding rod 22, and rotate the threaded ring 28 to move the threaded ring 28 on the outer surface of the screw rod 27 to press one side tightly against the slot rod. The position of the sliding rod 22 is fixed on one side of 21, and then the elastic metal sheet 24 inside the U-shaped block 23 is pried apart, and the line is clamped between the elastic metal sheet 24 and the inner wall of the U-shaped block 23, and the elastic metal sheet 24 is loosened and pressed against the surface of the line to arrange and fix the line, and then the bolt 25 is turned to move the bolt 25 downward and press on the top of the elastic metal sheet 24, so as to further fix the position of the line inside the U-shaped block 23. When the composite switch device is working, the temperature of the circuit or equipment is monitored in real time through the temperature sensor built into the body 1, and the temperature signal is transmitted to the control system. When the temperature reaches or exceeds the preset threshold, the control system will take corresponding protection measures, cut off the power supply inside the body 1 or send an alarm signal. When the line needs to be repaired, the bolt 25 is turned away from the elastic metal sheet 24 and then the elastic metal sheet 24 is pried apart to take out the line.
