[0027] Workflow: First, fix the base plate 1 to the workbench through the mounting plate 2. Insert the engaging block 7 into the inner side of the engaging groove 3 at the top of the base plate 1 and align the first through hole 4 and the second through hole 8. Then, insert the positioning bolt 5 into the inner sides of the first through hole 4 and the second through hole 8 and screw the positioning nut 6 onto the outer side of the positioning bolt 5. Next, place the workpiece inside the fixed pressing plate 14, align the round hole 15 on the fixed pressing plate 14 with the fixing bolt 12 at the top of the placing plate 11 and press it down, and tighten the fixing nut 13 onto the outer side of the fixing bolt 12 to complete the fixing of the workpiece and the alignment of the workpiece. When it is necessary to adjust the height of the workpiece, take out the pin 1005 from the inner sides of the first through groove 1003 and the second through groove 1004. Then, move the fixing plate 1002 inside the fixed cylinder 1001 to make the fixing plate 1002 slide inside the fixed cylinder 1001 at the top of the support plate 9, adjust the workpiece to the appropriate height, and insert the pin 1005 into the inner sides of the first through groove 1003 and the second through groove 1004 to complete the height adjustment of the workpiece. The adjustment component 10 enables the height of the workpiece to be freely adjusted according to requirements. When the rubber plate 1608 is damaged and needs to be replaced, pull the baffle 1604. At this time, the insertion rod 1602 slides inside the first insertion hole 1601 and the second insertion hole 1607 and disengages from the second insertion hole 1607, and the return spring 1603 is compressed under force. Remove the rubber plate 1608 to make the positioning block 1606 disengage from the positioning groove 1605. Then, insert the positioning block 1606 at the top of the new rubber plate 1608 into the inner side of the positioning groove 1605 and release the baffle 1604. At this time, the return spring 1603 resets to drive the insertion rod 1602 to slide inside the first insertion hole 1601 and the second insertion hole 1607 and insert into the second insertion hole 1607 to complete the replacement of the rubber plate 1608. The setting of the anti-slip component 16 makes the fixing of the device to the workpiece more firm and makes the replacement of the rubber plate 1608 more convenient.
