6462.Photoelectric counter 6462 is fixed on installing plate 640.Optical disc 6460 is fixedly connected with an installed part 644.Three screw mandrels 645
Line it is triangular in shape.
Please continue to refer to Fig. 5 to Fig. 7, flexible connecting structure 65 includes support bar 652, buckling piece 653, resistance to compression bolster
654th, fastener 655, the first installation sheet 656, bottom bolster 657, the second installation sheet 658 and installation set 659.Support bar 652
Provided with buckle face 6520.Buckling piece 653 is provided with mounting hole 6530 and block button hole 6532.Block button hole 6532 connects with mounting hole 6530
It is logical.The diameter of mounting hole 6530 is more than the diameter of block button hole 6532.First installation sheet 656 is sheathed on the end of support bar 652, bottom
Bolster 657 is sheathed on the end of support bar 652 and contradicted with the first installation sheet 656.Bottom bolster 657 is by elastomeric material system
Into.Support bar 652 is rotatablely installed on bottom plate 612 through the through hole on bottom plate 612.Now bottom bolster 657 is held in
Between the installation sheet 656 of bottom plate 612 and first.The installation sheet 658 of resistance to compression bolster 654 and second is sheathed on support bar 652, and resistance to compression is delayed
Stamping 654 is between the second installation sheet 658 and bottom plate 612.Buckling piece 653 is sheathed on support bar 652 by mounting hole 6530,
The movement of the relative support bar 652 of buckling piece 653 makes support bar 652 and the buckle of block button hole 6532, and buckling piece 653 passes through fastener 655
It is fixedly installed in bottom plate 612.Now due to block button hole 6532 and the buckle of buckle face 6520, support bar 652 be fixed on bottom plate 612 with
Prevent the opposed bottom 612 of support bar 652 from rotating.Installation set 659 is fixed on the end of support bar 652.Support bar 652 is provided with mating holes

Installing plate 640 rotates.Tumbler 642 drives installed part 644 to rotate by driving member 643.Installed part 644 drives the phase of screw mandrel 645
Installation set 659 is rotated, because installation set 659 is internally threaded, therefore set 659 is mounted opposite while the rotation of screw mandrel 645
Move up and drive whole lifting structure 64 to move up, therefore wax injection device moves up.Optical disc 6460 is with installed part
644 rotate, and photoelectric counter 6462 calculates the adjustable height of wax injector jacking system 60 by the rotation of optical disc 6460.Work as note
When wax machine jacking system 60 is made the generation skew of 3 screw mandrels 645 by horizontal force, because resistance to compression bolster 654 and bottom delay
Stamping 657 is made up of rubber, belongs to flexible articles, can bear the maximum 8 degree of inclinations of screw mandrel 645.And inside connecting base bearing 651
For ball bearing, there is the characteristic for allowing axis body to offset on a large scale.Screw mandrel 645 is stretched into inside the mating holes 6522 of support bar 652,
It is overall not in when part processes decentraction or installation because the diameter of mating holes 6522 is bigger 2mm than the diameter of screw mandrel 645
During heart position, wax injector jacking system 60 is appointed can normal work.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
Corresponding change and deformation, and all these changes and deformation should all belong to the protection domain of the claims in the present invention
Within.
