The motor 8 can drive the rotating rod 20 to rotate. During the rotation of the rotating rod 20, the drive gear 19 can rotate together.

[0044] Working principle: In use, the operator first places the circuit board 12 on the top of the platform 1 and presses one side against the mounting plate 5. Then, the operator turns the handle 4, which drives the threaded screw 27 to rotate. During the rotation of the threaded screw 27, the two sets of threaded sleeves 26 meshing on its outer wall move in opposite directions. During the movement of the threaded sleeves 26, the two clamping rods 13 can effectively clamp and fix the circuit board 12, ensuring the stability of the circuit board 12 during the subsequent drilling process. After the circuit board 12 is fixed, the motor 8 starts, which drives the rotating rod 2... The rotating rod 20 rotates, causing the drive gear 19 to rotate as well. The drive gear 19 rotates, which in turn drives four sets of driven gears 21 to rotate. The rotation of the driven gears 21 allows the four drill bits 9 to simultaneously drill holes in the circuit board 12, greatly improving the drilling efficiency of the circuit board 12. At the same time, the rotating rod 20 also drives the bushing 23 to rotate. The simultaneous rotation of the bushing 23 and the fan blade 22 creates a negative pressure suction inside the waste bin 10, which can suck the debris generated during drilling into the waste bin 10 for collection, ensuring the cleanliness of the top of the platform 1.
