[0036] Embodiment 2

[0037] See also Figure 1-7On the basis of the first embodiment, the pressing mechanism 3 further comprises a T-shaped rotating rod 33, which is fixedly connected to the top of the workbench 1, and a rotating plate 34 is rotatably connected to the surface of the T-shaped rotating rod 33, and a pressing plate 36 is fixedly connected to the inner side of the rotating plate 34, and the pressing plate 36 is arranged on the top of the circuit board 2. Long grooves 31 are opened on the inner sides of the left and right rotating plates 34, and long plates 32 are fixedly connected to the top of the workbench 1, and first bolts 35 are threadedly connected to the inside of the long plates 32 and the rotating plates 34, and the top, bottom and side of the long groove 31 close to the circuit board 2 are arranged as openings, and the surface of the long plate 32 and the inside of the long groove 31 are plugged in.

[0038] Furthermore, by moving the rotating plate 34 to rotate on the surface of the T-shaped rotating rod 33 until the rotating plate 34 drives the pressing plate 36 to be set on the top of the circuit board 2, the circuit board 2 can be restricted and fixed on the top of the workbench 1, avoiding the circuit board 2 from moving randomly when a handheld puncher is used to punch holes in the circuit board 2 later.

[0039] In actual operation, when the device is used, when it is necessary to punch holes in the circuit board 2, the circuit board 2 is first placed on the top of the workbench 1, and the rotating plate 34 is turned to rotate on the surface of the T-shaped rotating rod 33 until the rotating plate 34 drives the pressing plate 36 to be set on the top of the circuit board 2, and the long plate 32 can also be inserted into the long groove 31. When the long plate 32 and the rotating plate 34 are screwed and fixed by the first bolt 35, the circuit board 2 can be restricted and fixed on the top of the workbench 1, so as to avoid the circuit board 2 from moving randomly when the puncher is used to punch holes in the circuit board 2 later;

[0040] When punching holes in the circuit board 2, debris will be generated. The motor 511 can be started while the holes are being punched. The motor 511 drives the worm 513 to rotate. Since the worm 513 drives the pulley 514 to rotate, the pulley 514 drives the belt 515 to rotate. At this time, the rotation of the worm 513 on the left can also drive the worm 513 on the right to rotate in the same direction. When the worm 513 rotates, it can also drive the two worm wheels 517 to rotate in the same direction at the original position. When the worm wheel 517 rotates, it can also drive the rotating shaft 512 to rotate at the bottom of the inner wall of the collection box 4. At this time, the rotating shaft 512 can also drive the suction fan blades 516 to rotate to suck the debris into the collection box 4, which can prevent the debris from scattering to a certain extent.

[0041] Later, after the second bolt 529 is removed from the thread, the connecting plate 528 is pulled so that the connecting plate 528 drives the plug 5201 to be taken out of the slot 526, and the filter plate 522 is pulled again so that the T-plate 523 slides in the T-slot 525, and the block 521 is moved out of the square slot 524, so that the debris accumulated on the filter plate 522 and the precision filter plate 527 can be collected later.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
