The principle of the present invention is: during installation, first by male fixture 11 and female fixture 12 difference of breastbone closing fixer 1
Navigate to, on male fixture draft arm 22 and female fixture draft arm 23 of installation tool 2, make the first location of public fixture 11
Hole 1116 matches with the positioning boss 221 of male fixture draft arm 22, the mother of female fixture 12 and female fixture draft arm 23
Fixture locating slot 231 matches, the locating dowel 233 of the second hole, location 1221 of female fixture 12 and female fixture draft arm 23
Match；Then the trip bolt 222 on male fixture draft arm 22 and two location on female fixture draft arm 23 are tightened
Screw 232, make trip bolt 222 match with the screw 1117 of male fixture 11, two location screws 232 fix with mother respectively
Two detents 1214 of part 12 match；Then public fixture is driven to lead by the first drive mechanism 25 of installation tool 2
Draw arm 22 to move on crossbeam 21, such that it is able to control between the male fixture 11 of breastbone closing fixer 1 and female fixture 12
Distance, regulation is opened the width of breastbone, is adjusted to suitable position, by the locking wheel of breastbone closing fixer 1, public affairs are solid
Locking member 11 and female fixture 12 are locked, and finally installation tool 2 are separated with breastbone closing fixer 1.
During dismounting, the first locking wheel of releasing breastbone closing fixer 1 extruding to public fixture 11.If public fixture 11
First helical teeth 1114 can be automatically disengaged from the second helical teeth 1212 of female fixture 12 by elastic, the most directly removes public fixture
11 and female fixture 12.If public fixture 11 creates plastic deformation, then by the guide pad of the main body guide post 31 of extracting tool 3
311 match with the gathering sill 1112 of public fixture 11, and the pushing block 321 of movable push bar 32 and public fixture 11 are pushed away groove
1121 match；Then drive movable push bar 32 to move on main body guide post 31 by the second drive mechanism 33, make public fixing
Distance between part 11 and female fixture 12 reduces further, and the first helical teeth 1114 of the most male fixture 11 can be fixed by mother
Second helical teeth 1212 of part 12 extrudes, and makes the engagement between the first helical teeth 1114 and the second helical teeth 1212 release, thus has
The male fixture of dismounting 11 of effect and female fixture 12.
Particular embodiments described above, has been carried out the purpose of the present invention, technical scheme and beneficial effect the most in detail
Describe in detail bright, be it should be understood that the specific embodiment that the foregoing is only the present invention, be not limited to the present invention, all
Within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. done, should be included in the guarantor of the present invention
Within the scope of protecting.
