The power meter body 1 has a cover plate 2 at the front end, which can cover the terminal block 3. A push rod 6 is fixedly connected to the front end of the cover plate 2, which can easily remove the cover plate 2. The lower end of the cover plate 2 has a wiring notch 4, the number of which is the same as the number of terminal blocks 3, to facilitate the connection of wires.

[0021] A spring 8 is fixedly connected to the lower inner wall of the cover plate 2, and a moving rod 7 is fixedly connected to the upper end of the spring 8. The upper end of the moving rod 7 extends through the outside of the cover plate 2. A rotating rod 9 is rotatably connected to the upper inner wall of the cover plate 2. The rotating rod 9 is sleeved on the moving rod 7. A slider is fixedly connected to the outer wall of the moving rod 7. A spiral groove adapted to the slider is opened on the inner wall of the rotating rod 9. When the moving rod 7 moves up and down, the rotating rod 9 is driven to rotate under the action of the slider and the spiral groove. Four fixed plates 13 are slidably connected inside the cover plate 2. One end of the four fixed plates 13 can extend through the inside of the wiring notch 4. Four fixing plates 13 are fixedly connected to one end of the cover plate 2, and a toothed strip 11 is fixedly connected to the connecting rod 12. A gear 10 is fixedly connected to the outer wall of the rotating rod 9. The gear 10 and the toothed strip 11 are in a meshing state. When the rotating rod 9 rotates, the toothed strip 11 can be moved under the action of the gear 10, and then the fixing plates 13 are moved through the connecting rod 12. A fixing groove 14 is opened at the front end of the energy meter body 1. By moving part of the fixing plate 13 into the fixing groove 14, the wire can be fixed to prevent the wire from loosening due to vibration.

[0022] The side of the fixing plate 13 that contacts the wire is designed with an arc surface, which makes it easy to fix wires of different thicknesses. A fixing sponge 15 is fixedly connected to this arc surface.

[0023] A limiting strip 16 is fixedly connected to the front end of the main body 1 of the electricity meter. A limiting groove 18 adapted to the limiting strip 16 is provided on the cover plate 2. By aligning the limiting groove 18 with the limiting strip 16, the installation position of the cover plate 2 can be accurately found. A locking block 17 is also connected to the side wall of the limiting strip 16 by a spring post. A locking groove 19 adapted to the locking block 17 is provided on the inner wall of the limiting groove 18. By inserting the locking block 17 into the locking groove 19, the installation of the cover plate 2 can be completed. When removing it, simply push it downward with force using the push rod 6.

[0024] The working principle of this utility model is as follows: When the device is needed, simply install the main body 1 of the electricity meter in a suitable position, then remove the cover plate 2 from the main body 1 of the electricity meter, and install the wire onto the terminal block 3. Next, align the limiting groove 18 with the limiting strip 16 and push the cover plate 2 upwards. When the cover plate 2 moves to the top, the locking block 17 engages with the slot 19, thus completing the installation of the cover plate 2. To remove it, simply move it downwards in the opposite direction. This facilitates disassembly and assembly, and makes it convenient to use. When the cover plate 2 moves to the top, at this time... When the main body 1 of the electricity meter is in a limited position, the moving rod 7 moves into the inside of the cover plate 2 and squeezes the spring 8. At this time, under the action of the slider and the spiral groove, the rotating rod 9 can be driven to rotate. Then the gear 10 will follow the rotating rod 9 to rotate, thereby driving the fixing plate 13 to move through the toothed strip 11 and the connecting rod 12. When the fixing plate 13 moves into the inside of the fixing groove 14, the wire can be fixed. The fixing sponge 15 will also protect the wire and completely seal the wiring notch 4 to prevent dust from entering.
