In figure：1. shaft；2. supporting sleeve；3. swollen key；4. left support set；5. sliding sleeve；6. separation sleeve；7. resetting spring；
8. inner screw sheath；9. external thread sleeve；10. outer-hexagonal set；11. skewback；12. the first inclined-plane.
Specific implementation mode
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.
A kind of mechanical expanding shaft as illustrated in fig. 1 and 2, including shaft 1, fixing sleeve is equipped with supporting sleeve 2, supporting sleeve 2 in shaft 1
Several radial through-hole being evenly distributed are equipped with, are equipped with movable swollen key 3 in radial through-hole, 2 both ends of supporting sleeve are fixed respectively
There are left support set 4 and right support set, left support set 4 and right support set to be set in shaft 1, left support set 4 and shaft 1 are tight
Match and be keyed with shaft 1,
It is set with several sliding sleeves 5 in the shaft 1, sliding sleeve 5 passes through the feather key and shaft 1 that are arranged in shaft 1
Key connection, is equipped with separation sleeve 6 of the movable set in shaft 1 between sliding sleeve 5, the sliding sleeve 5 and left support set 4 of left end it
Between be equipped with the resetting spring 7 that offsets with the two, resetting spring 7 is sleeved in shaft 1, sliding sleeve 5 and the right support set of right end
Between be equipped with inner screw sheath 8 and external thread sleeve 9 of the movable set in shaft 1,9 left end of external thread sleeve respectively and stretch into internal thread
It covers in the screw hole of 8 right ends and is spirally connected with it, 9 right end of external thread sleeve is extended axially through after right support set endoporus extends outwardly and is fixedly connected
There is outer-hexagonal to cover 10,
The swollen key 3 has fixedly connected to the inner side skewback 11, and 11 inside of skewback is equipped with the first inclined-plane 12, and the sliding sleeve 5 is equipped with
Several guide grooves corresponding with 2 radial through-hole of the supporting sleeve are oriented to trench bottom and are equipped with and 11 first inclined-plane of skewback, 12 phase
The second inclined-plane matched, 11 inside of skewback are stretched into 5 guide groove of sliding sleeve through its first inclined-plane 12 and the second inclined-plane of guide groove phase
Fitting.
In use, by drum sheath on supporting sleeve 2, outer-hexagonal set 10 is pulled with spanner, outer-hexagonal set 10 drives outer spiral shell
Line set 9 rotation, to drive inner screw sheath 8, sliding sleeve 5 and separation sleeve 6 to move to left, at the same resetting spring 7 compress, according to inclined-plane by
