Further, the outer convex part in the upper end of convex dop divides to be spherical chamfer structure, and when the barre was wrench movement to violence, because convex dop upper end is spherical chamfer, can the lapse break away from the draw-in groove when the violence was wrench movement, at this moment the barre is rotatory alone, and outer handle subassembly can't be wrench movement, can not lead to the lock core to damage.

Furthermore, the lower end of the handle rod adopts a cylindrical structure, so that the handle cannot be pressed against the hand during twisting, and the handle is more comfortable.

Compared with the prior art, the utility model has the advantages of:

(1) through adopting outer handle and barre components of a whole that can function independently structure, when the barre violently pushes down, the barre autogyration can not drive outer handle and rotate together, can not destroy the lock core, can not lead to the lock to open, improves the security performance.

(2) The threaded sleeve adopts a hexagonal ring sleeve structure, an internal thread is arranged at the inner end of the threaded sleeve and matched with an external thread of the outer handle, and the handle rod can be extruded and positioned by installing the threaded sleeve.

(3) The inner handle is sleeved with a rubber pad, and the threaded sleeve is extruded on the rubber pad, so that the tightness degree during extrusion and fixation is improved, and the friction force is improved.

(4) The convex part is divided into spherical chamfer structure to the upper end of convex dop, when the barre is wrench by violence, because convex dop upper end is spherical chamfer, can slide downwards when wrench by violence break away from the draw-in groove, at this moment the barre is rotatory alone, can't wrench by twisting outer handle subassembly, can not lead to the lock core to damage.

(5) The lower end of the handle rod adopts a cylindrical structure, so that the handle cannot be pressed against the hand during twisting, and the handle is more comfortable.
