[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0019] Please see Figures 1 to 4 The utility model provides a technical solution:

[0020] A power meter replacement device includes a meter body 1 and a mounting plate 2. Two L-shaped limiting plates 3 are movably mounted on the surface of the mounting plate 2, and the two L-shaped limiting plates 3 are arranged opposite to each other. The meter body 1 is located between the two L-shaped limiting plates 3. Several fixing plates 4 are arranged on the surface of the mounting plate 2 through a second torsion spring. Under the action of the second torsion spring, an upward force is always provided to the fixing plates. The fixing plates 4 are staggered at the wiring holes at the bottom of the meter body 1. A wire clamping device is also provided on the surface of the mounting plate 2, and a quick disassembly assembly is provided between the two L-shaped limiting plates 3.

[0021] Specifically, the meter body 1 is supported at the bottom by several fixing plates 4 and hugged by two L-shaped limiting plates 3 on both sides, so that the meter body 1 can always be in contact with the mounting plate 2. A first torsion spring 5 is provided between the bottom of the wall of the L-shaped limiting plate 3 and the surface of the mounting plate 2. A groove is provided on the surface of the mounting plate 2, and a return spring 6 is fixedly installed inside the groove. The other end of the return spring 6 is fixedly connected to the top of the wall of the L-shaped limiting plate 3. That is, by external force, the L-shaped limiting plate 3 can be flipped towards the bottom of the meter body 1. At the same time, the front end of the meter body 1 will tilt along with the surface of the L-shaped limiting plate 3. At the same time, the second torsion spring will also be driven to tilt together. At this time, the meter body 1 can be removed.

[0022] The wire clamping device includes a first wire clamping plate 7 and a second wire clamping plate 8, which are joined together by mortise and tenon joints. Several matching semi-circular grooves are provided on opposite sides of the first and second wire clamping plates 7 and 8. Two semi-circular grooves are joined to form a circular slot 9. A hemispherical body 10 is rotatably disposed within each of the two semi-circular grooves. A wire groove 11 is provided between the two hemispherical bodies 10, and the two wire grooves 11 are matched to clamp the wire. Before use, the wire is first passed through the wire groove 11, then inserted into the bottom interface of the meter body 1. The first and second wire clamping plates 7 and 8 are then joined together by mortise and tenon joints to fix the wire. When replacing the meter body 1, the wiring operation of the meter body 1 can be simplified.

[0023] The quick-release assembly includes a horizontal plate 15 positioned between two L-shaped limiting plates 3. The surface of the horizontal plate 15 has several disassembly holes 12, each containing a screwdriver bit 17 that can be rotatably mounted. A rotary motor 16 is also mounted on the surface of the horizontal plate 15. A drive rod 13 is mounted at the output end of the rotary motor 16 and rotatably passes through the interior of the horizontal plate 15. Gears are fixedly mounted on the surfaces of the drive rod 13 and the screwdriver bit 17 inside the horizontal plate 15. A toothed belt 14 is connected to both the gears on the drive rod 13 and the screwdriver bit 17. Several screwdriver bits 17 are connected by a toothed belt 14; and the other end of the screwdriver bits 17 is inserted into the cross-slot screw of the meter body 1. When the meter body 1 needs to be replaced, the same operation is performed. First, the meter body 1 is tilted; then the rotating motor 16 is started to drive the screwdriver bits 17 to rotate, thereby quickly separating the wire from the wiring port of the meter body 1. Similarly, during installation, the new meter body 1 is tilted and inserted, and then the rotating motor 16 is reversed to lock the wire to the wiring port of the meter body 1, thus completing the installation.

[0024] As a preferred option, a baffle can be provided on the surface of the mounting plate 2. The baffle is located on the top of the meter body 1, which can prevent the meter body 1 from being removed vertically after installation. At the same time, the baffle will not affect the tilt of the meter body 1.
