[0037] The use principle of the utility model is now described as follows:

[0038] The handle 24 is used to pull the fixing plate 2 so that the fixing plate 2 is gradually moved out of the second concave cavity 16 and protrudes out of the box body 1. The inclined surface 9 of the stop block 31 is moved on the inclined surface 9 of the stop groove 12 under the influence of the pulling force, thereby causing the stop block 31 to move in the direction of the first magnet 213 and causing the spring 33 to gradually accumulate energy. When the stop block 31 is completely separated from the stop groove 12, the stop block 31 and the first magnet 213 are still at a distance that cannot be attracted. Therefore, the stop block 31 will enter the next stop groove 12, and the spring 33 releases the reaction force to push the stop block 31 to tightly abut the stop groove 12, so that the fixing plate 2 is fixed in the current stop groove 12. When the retaining ring 133 abuts the first countersunk hole 23, it means that the fixing plate 2 has reached the maximum limit of being pulled out. The above design increases the operating space for installing the meter connector 5, the energy meter 7, the air switch 6, and the wiring, and increases the light brightness, so that the installer can better see the working area, reduce operating errors and bury safety hazards;

[0039] When the installation and wiring operations are completed and the fixing plate 2 needs to be retracted into the second concave cavity 16, the push block 313 is used to make the stop block 31 abut against the end face of the movable through hole 21, so that the first magnet 213 and the second magnet 32 ​​are attracted to each other to prevent the stop block 31 from extending out due to the reaction force of the spring 33. When all the stop blocks 31 of the fixing plate 2 are operated according to the above steps, the fixing plate 2 that has lost its fixation can be pushed, and the buffer member 4 reduces the movement speed of the fixing plate 2 to prevent the fixing plate 2 from hitting the box body 1 at too fast a movement speed, until the fixing plate 2 abuts against the support column 131, and the top block 163 causes the stop block 31 to be attracted and separated from the first magnet 213, and the spring 33 releases the reaction force to push the stop block 31 to abut against the stop groove 12, thereby completing the fixation of the fixing plate 2.

[0040] The above design scheme can enable the product to achieve the advantages of improved installation efficiency, easy wiring and simple operation.

[0041] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
