2. The power metering box of claim 1, further comprising a reset mechanism comprising a sliding clip, the sliding clip being slidably coupled to the housing; one end of the sliding clamping strip is connected with a second magnet; the sliding clamping strip is also connected with a fourth spring, and the fourth spring is connected with the shell; the shell is also rotationally connected with a first magnet, and a key hole is formed in the first magnet; the key is matched and inserted with the key hole; the follow-up rod outer wall is connected with a clamping block, the clamping block is provided with an inclined plane, and the clamping block is in fit connection with the sliding clamping strip.
3. The power metering box of claim 2, wherein the box door is provided with a through hole for a key to pass through.
4. A method for using the power metering box, which adopts the power metering box as claimed in claim 3, is characterized in that the specific method is as follows:
when the anti-theft switch is in normal use, the door is closed, and the anti-theft switch is normally electrified to work; when the box door is opened, the extruding column of the box door can not limit the sliding shaft any more, and at the moment, the sliding shaft slides under the action of the elastic force of the third spring; the sliding shaft drives the wedge block to move together in the sliding process, the wedge block drives the follow-up rod to move when moving, and the second spring is compressed; the follow-up rod can drive the first connecting rod to rotate around the pin shaft when moving, the first connecting rod can drive the rack to move when rotating, the rack moves to drive the gear to rotate so as to drive the turntable to rotate, the turntable can drive the third connecting rod to move in the rotating process, the third connecting rod moves to drive the second connecting rod to move so as to drive the insulating plate to move, and the insulating plate is inserted between the conducting strip and the external terminal, so that power failure is realized; meanwhile, the conducting strip can drive the guide block to move, and the first spring generates elasticity.
5. The method of claim 4, wherein after the door is opened, the follower rod drives the clamping block to move when moving, when the clamping block moves, the sliding clamping strip is extruded after touching the sliding clamping strip, the sliding clamping strip moves towards the direction approaching to the conducting strip, and the fourth spring is compressed to generate elastic force; when the clamping block moves to the position above the sliding clamping strip, the sliding clamping strip moves towards the direction close to the follow-up rod under the action of the elastic force of the fourth spring, so that the clamping block is clamped at the top of the sliding clamping strip; the insulating board is inserted between the conducting strip and the external terminal, so that power failure is realized, and the state is maintained;
if the door is opened when the worker overhauls, the door is closed after the overhauling is finished, and the extruding column on the door can extrude the sliding shaft at the moment, so that the sliding shaft is reset; because the staff is provided with a corresponding key, the key is penetrated into the key hole through the through hole, and the first magnet is rotated; the attractive force between the rotated first magnet and the second magnet is increased, so that the second magnet drives the sliding clamping strip to move in the direction away from the follow-up rod, and further the limit is released, and the follow-up rod drives the clamping block to move and reset under the action of the elastic force of the second spring; in the resetting process, the follow-up rod drives the first connecting rod to reversely rotate, so that the rack reversely moves and the turntable reversely rotates; the second connecting rod is driven to move reversely by the third connecting rod, so that the insulating plate is pulled away from the position between the conducting strip and the external terminal; the conducting strip resets under the action of the elastic force of the first spring and contacts with the external terminal, so that electrifying is completed.
