Changed on ground.Spline fitted connects, and connection is reliable.Anti-avulsion head and drop-proof hole are set, can prevent from moving axially.Need to prevent
During axial movement, rotation of drive rod causes the depth increase that drive rod enters in operation hole, and conical surface section pushes into anti-avulsion pin only
In de- hole.It is on the contrary then rotate backward drive rod.In order to lose anti-avulsion pin energy after the ejection effect to anti-avulsion pin in conical surface section
It is enough easily and reliably to be exited out of drop-proof hole, now it can be retracted to axle by design driven anti-avulsion pin between anti-avulsion pin and drop-proof hole
Anti-avulsion pin in head exits spring.
Preferably, the anti-avulsion pin is the same as being cone match between the conical surface section.Not easily leaded to when driving anti-avulsion pin
Conical surface segment table surface wear.
Preferably, being provided with axis hole in the rotor, the both ends of the axis hole are provided with big footpath section, and the spindle nose is connected to institute
State in big footpath section, the end face of the end face of the spindle nose and the big footpath section abut together with when, the drop-proof hole and anti-avulsion pins position
In in the plane of the same axis perpendicular to the rotor.Convenience when anti-avulsion pin and drop-proof hole alignment can be improved.
Preferably, the rotor is provided with the locating slot extended along rotor axial, the spindle nose is provided with axially to be prolonged along spindle nose
The positioning convex strip stretched, when the positioning convex strip is plugged in the locating slot, the drop-proof hole and anti-avulsion pin correspond status
In in the plane of the same axis by the rotor.Convenience when anti-avulsion pin and drop-proof hole alignment can be improved.
The utility model tool has the advantage that：Spindle nose can be changed independently, reduce maintenance cost；Rotating shaft is not allowed
It is also easy to produce axial movement.
