[0021] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, when installing the circuit breaker, the fixing base 1 can be permanently installed inside the meter box, and then the circuit breaker body 11 can be installed on one side of the fixing base 1. Since a double-threaded worm 2 is installed inside the fixing base 1, and a slider 15 is respectively sleeved on the outer sides of both ends of the double-threaded worm 2, and one end of the slider 15 extends out of the fixing base 1 and a fixing block 13 is installed inside, and one end of the fixing block 13 is equidistantly installed with a plurality of limit plug rods 5, therefore, by rotating the double-threaded worm 2, the two sliders 15 can be driven to slide relatively along the installation direction of the double-threaded worm 2, and at the same time, the two fixing blocks 13 can be driven to move relatively on one side of the fixing base 1, so as to adjust the distance between the two fixing blocks 13. Since one side of the circuit breaker body 11 is installed A base 10 is installed, and a support plate 6 is installed on one side of the base 10, and a limit hole 7 is opened inside the support plate 6. Therefore, when installing the circuit breaker body 11, the bottom ends of the two support plates 6 can be leaned against one side of the fixed base 1, and then the two fixed blocks 13 are controlled to move relative to each other, so that the limit plug rod 5 installed at one end of the fixed block 13 is inserted into the inside of the limit hole 7, so that the circuit breaker body 11 is fixed to one side of the fixed base 1. Since a knob 14 is installed on one side of the fixed base 1, and the output end of the knob 14 extends into the inside of the fixed base 1 and is connected to one end of the double-thread worm 2, the double-thread worm 2 can be driven to rotate by rotating the knob 14, so that it is convenient for the operator to disassemble and assemble the circuit breaker body 11.

[0022] Embodiment 2: A fixing plate 4 is respectively installed at both ends of the fixing seat 1, and a fixing hole 3 is opened inside the fixing plate 4, a slider 15 is slidably sleeved on the outer side of the supporting slide rod 16, and the slider 15 is connected to the double-thread worm 2 by threaded engagement, a connecting wire 8 is installed on the top of the base 10, and a lever 12 is installed on one side of the circuit breaker body 11, the connecting wire 8 and the lever 12 are used together, a plurality of line interfaces 9 are equidistantly opened on the top of the circuit breaker body 11, a slide groove 17 is opened on one side of the fixing seat 1, and one end of the two sliders 15 are slidably installed inside the slide groove 17 respectively.

[0023] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, since a fixing plate 4 is respectively installed on both sides of the fixing seat 1, and a fixing hole 3 is provided inside the fixing plate 4, the entire fixing seat 1 can be installed inside the meter box through the fixing plate 4 and the fixing hole 3. Since a connecting wire 8 is installed on the top of the base 10, the circuit breaker body 11 can be electrically connected to the electric meter through the connecting wire 8. Since a line interface 9 is provided at the top of the circuit breaker body 11, the circuit breaker body 11 can be connected to the circuit through the line interface 9. The opening and closing state of the circuit breaker body 11 can be controlled by the lever 12. Since a slide groove 17 is provided on one side of the fixing seat 1, the slide groove 17 can ensure that the two sliders 15 can slide normally. Since the slider 15 is connected to the double-thread worm 2 through threaded engagement, when the double-thread worm 2 rotates, the two sliders 15 can slide along the installation direction of the double-thread worm 2. At the same time, the slider 15 is slidably sleeved on the outer side of the supporting slide rod 16, and the stability of the movement of the slider 15 can be ensured by the supporting slide rod 16.

[0024] Working principle: When in use, since a fixing plate 4 is installed on both sides of the fixing seat 1, and a fixing hole 3 is opened inside the fixing plate 4, the entire fixing seat 1 can be installed inside the meter box through the fixing plate 4 and the fixing hole 3, and then the circuit breaker body 11 can be installed on one side of the fixing seat 1, and the bottom ends of the two support plates 6 are placed against one side of the fixing seat 1. By rotating the knob 14, the double-grained worm 2 can be driven to rotate, and the two sliders 15 can be driven to slide relatively along the installation direction of the double-grained worm 2, and at the same time, the two fixing blocks 13 can be driven to move relatively on one side of the fixing seat 1, so as to adjust the two fixings. The spacing between the blocks 13 is adjusted so that the limiting plug rod 5 installed at one end of the fixing block 13 is inserted into the inside of the limiting hole 7, so that the circuit breaker body 11 is fixed to one side of the fixing seat 1 to complete the installation of the circuit breaker body 11, and then the circuit breaker body 11 is connected to the circuit, and the circuit breaker body 11 can be electrically connected to the electric meter through the connecting line 8, so as to realize the functions of opening the circuit breaker for arrears and closing the circuit breaker for payment. When removing the circuit breaker body 11, it is only necessary to rotate the knob 14 in the reverse direction to make the limiting plug rod 5 slide out of the limiting hole 7 to remove the circuit breaker body 11 from one side of the fixing seat 1, which is very convenient.
