Wherein it should be said that, compression spring 16 that sets up coaxially on perforating needle 17, and annular contact 14 and metal disc 15 that set up at both ends, wherein annular contact 14 links to each other with negative pole ring 5 on the panel 4, and panel 4 and the coaxial fixed setting of first pivot 7, be convenient for drive at spacing wheel 1 like this and wear needle ring 2 and rotate, and be provided with annular magnet 11 between first pivot 7 and second pivot 8, it should be said that, the outer lane and the inner circle of annular magnet 11 are the magnetism that the magnetic pole is opposite, and it is provided with a plurality of balls 12 that are fixed by the support to be the circumference on annular magnet 11 inner circle, can act as the effect of antifriction bearing like this, provide the supporting effect for annular magnet 11 at first pivot 7 lateral wall.
Then, because the positive contact 6 on the battery plate 4 is always located between the flexible track 18 and the first rotating shaft 7, namely located on a vertical surface, when the needle penetrating ring 2 drives the compression spring 16 to rotate to the vertical surface, the metal disc 15 on the top of the compression spring 16 can touch the positive contact 6, at the moment, the positive contact 6 is communicated with the negative ring 5 through the metal disc 15, the compression spring 16 and the annular contact piece 14, and current flows through the compression spring 16.
It should be noted that originally, the metal disc 15 is attracted by the ring magnet 11, current flows through the compression spring 16, the compression spring 16 can be regarded as an energized solenoid to form a magnetic field, so that a magnetic pole is generated on the metal disc 15, the magnetic pole generated on the metal disc 15 is the same as the magnetic pole on the outer ring of the ring magnet 11, and thus a repulsive phenomenon is generated, the metal disc 15 can push the punching needle 17 to descend under the action of the repulsive force, the punching needle can prick the brittle panel in the descending process to complete one-time punching on the brittle panel, when the metal disc 15 finishes the punching by descending the punching needle 17 with the punching needle 15, the metal disc 15 lifts up with the punching needle 17 under the elastic action of the compression spring 16, and at this time, the punching ring 2 rotates with the compression spring 16 to deviate from the original position, and the metal disc 15 is not in contact with the positive contact 6 any more, so that no current is generated.
It should be noted that, at this time, since the flexible track 18 is in an irregular shape, the hole made on the brittle panel by the punching needle 17 will generate a separation hole in a round-to-round punching process, and at this time, only the required brittle panel needs to be removed.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
