By adopting above-mentioned technical proposal, chain rivet is inserted in step axis body, chain rivet is rotated and card key is supported with limited block
Touch, now pull chain rivet, chain rivet to be limited by limited block and cannot be deviate from vitro to step axle, user is again by jack and through hole
It is aligned, the slip that chain rivet is restricted and is not susceptible on axial direction, is more prone to when latch is inserted, facilitates.
This utility model is further arranged to：Curved angle of the curved angle of the card key less than limited block, limited block
The draw-in groove with card key form fit is provided with away from the side of step axle body end mouth；When in card key insertion draw-in groove, jack aligned through holes.
By adopting above-mentioned technical proposal, after chain rivet is inserted in step axle body, rotate chain rivet and drawn to step axle in vitro,
It is fixed in card key insertion draw-in groove on chain rivet, now jack just aligned through holes, user insertion latch can just complete chain
The fixation of axle, easy to operate, high working efficiency.
This utility model is further arranged to：The draw-in groove is provided with targeting port.
By adopting above-mentioned technical proposal, along in targeting port insertion draw-in groove, targeting port makes the insertion of card key more to card key
Easily.
This utility model is further arranged to：The number of the card key is two, and card key is along the circumferential uniform of leading section；Limit
The number of position block is two.
It is distributed on leading section by adopting above-mentioned technical proposal, two card keys, when card key is contradicted with limited block, chain rivet exists
Fix more firm in step axle body.
This utility model is further arranged to：Fixture block is provided with the step axle body, when contradicting after card key turns and with fixture block,
Jack aligned through holes.
By adopting above-mentioned technical proposal, chain rivet after chain rivet is inserted in step axle body, is rotated, when card key is contradicted with fixture block,
Chain rivet cannot be rotated, while jack just aligned through holes, latch insertion can just be completed user the fixation of chain rivet, operation side
Just, high working efficiency.
This utility model is further arranged to：Including clamp, the outer surface of step axis body is provided with for placing clamp
Annular groove, the section of annular groove is in inverted trapezoidal, the external step assembling set also including step axle is socketed in.
The effect of fixed step assembling set is primarily served by adopting above-mentioned technical proposal, clamp, clamp is fixed on annular groove
When interior, inverted trapezoidal annular groove is bigger with the contact area of clamp, and the pressure that ring groove surface is subject to is relative to be reduced, and reduces annular groove and mill occurs
The probability of damage.
In sum, this utility model has the advantages that：When chain rivet carries out grafting with step axis body, chain rivet is inserted
Afterwards and rotate chain rivet, card key insertion draw-in groove or when abutting with the fixture block on wall in step axle body, jack is aligned through holes, at this moment
User can just insert latch and be fixed, easy to use, reduce the operating time.
