Principle of embodiment:

in order to accelerate the debugging speed, a plurality of engineers often debug the laser cutting machine 200, specifically, each laser head 2111a is debugged by one engineer, the number of the laser heads 2111a is consistent with that of the key assemblies 12, and the key assemblies are in one-to-one correspondence with each other, in an initial state, the switch 14 is disconnected, the conductive post 1221 is disconnected from the conductive sheet 121, at this time, even if the switch 14 is closed, the laser heads 2111a cannot be electrified to work, and the laser heads 2111a can be effectively prevented from injuring the engineers. When debugging, an engineer debugs the corresponding laser head 2111a, after each laser head 2111a is debugged, the engineer respectively presses the corresponding conductive key 122 downwards to enable the conductive post 1221 to abut against the conductive sheet 121, at this time, the conductive wire 111 is communicated with the conductive sheet 121 through the conductive post 1221, at this time, another engineer closes the switch 14, so far, a first closed loop is formed between the conductive wire 111 and the key assembly 12, the metal block 1311a is adsorbed after the coil 1311b is electrified, the metal block 1311a moves towards the coil 1311b until the power transmission plate 1311d abuts against the electrode 1315, that is, the electrode 1315 is communicated through the power transmission plate 1311d, and at this time, the laser head 2111a is electrified to work, see fig. 6. This process is described in the orientation of the drawings, in which the protrusion 1311c rotates the rotation lever 1313, the top plate 132 moves downward first, the top plate 132 moves to the lowermost end when the rotation lever 1313 is perpendicular to the top plate 132, and the top plate 132 moves upward as the rotation lever 1313 continues to rotate. When the conductive plate 1311d and the electrode 1315 abut, the upper end of the rotating lever 1313 is inclined toward the coil 1311 b. At this time, the end of the pressing block 1311f is exposed to the outside of the case 131. At this time, the engineer may release the conductive button 122, and the conductive button 122 moves upward and is separated from the conductive sheet 121 by the first spring 123, the wires 111 are disconnected from each other, and the coil 1311b is disconnected, but the top plate 132 presses the rotating lever 1313 by the second spring 133, so that the conductive plate 1311d is always pressed against the electrodes 1315, and the electrodes 1315 are always connected to each other through the conductive plate 1311 d. When the laser head 2111a needs to be stopped, the pressing block 1311f is pushed, the metal block 1311a is away from the coil 1311b, the protrusion 1311c drives the rotating rod 1313 to rotate, the top plate 132 moves downwards and then upwards under the action of the rotating rod 1313, finally, the metal block 1311a is abutted to one side, away from the via hole 1312, of the shell 131, namely, the metal block 1311a returns to the initial state, in this case, the electrode 1315 and the current transmission plate 1311d are disconnected, the electrode 1315 is disconnected, and the laser head 2111a is powered off and stops working, as shown in fig. 5.

As an implementation manner, when the laser head 2111a works, a plate is fixed on the base 11, the motor 213 operates to drive the driving gear 212 to rotate, so as to drive the driven gear 2112 to rotate, the driven gear 2112 drives the turntable 211 to rotate, and the turntable 211 drives the laser head 2111a to make a circular motion, so as to perform annular cutting on the plate on the lower side of the laser head 2111 a.

As one implementation, one end of the laser head 2111a is connected to one of the electrodes 1315, the other end of the laser head 2111a is connected to the other electrode 1315, when the electrodes 1315 are connected through the current-conducting plate 1311d, a second closed loop is formed among the laser head 2111a, the electrodes 1315 and the current-conducting plate 1311d, and a driving power supply for driving the laser head 2111a is further provided in the second closed loop, and the driving power supply is connected to the motor 213 and is used for driving the motor 213 to operate.
