[0034] By adopting the above technical scheme, in the utility model, the handle seat 1 is specifically an outer door handle, the outer door handle is provided with the lock cylinder 75, the lock cylinder 75 is connected with the anti-lock assembly of an inner door handle through the rotating wheel 74 and the linkage rod 72, and thus the linkage during anti-lock is realized.

[0035] And the specific locking action is that the linkage rod 72 is operated to rotate, since the limiting sheet 73 is rotationally limited in the recessed groove 31, the two limiting sections 731 of the limiting sheet 73 enter the plug hole 65 through the through hole 5, thereby realizing the rotation limiting of the bottom sleeve part 61, that is, realizing the rotation limiting of the connecting sleeve assembly 6.

[0036] Wherein, the door lock base 8 is installed on the door, the handle base 1 and the door lock base 8 are relatively rotatable, since the door lock base 8 is fixedly connected with the plug sleeve assembly 62, namely in actual use, the handle base 1 can rotate, while the door lock base 8 and the connecting sleeve assembly 6 are not rotatable, and since the end of the torsion spring 64 abuts against the contact block 13, in use, the handle base 1 is rotated, the torsion spring 64 is compressed to provide a restoring force.

[0037] And when the linkage rod 72 is operated, specifically by inserting the key into the lock cylinder 75, the lock cylinder 75 drives the ratchet wheel 74 to rotate, the ratchet wheel 74 drives the linkage rod 72 to rotate, at this time the limiting section 731 is located in the insertion hole 65, the bottom sleeve assembly 61 is locked on the convex sleeve part 2, so that the handle base 1 cannot rotate relative to the connecting sleeve assembly 6, and the locking of the handle base 1 is completed.

[0038] And, compared with the prior art of locking the spherical surface of the ball, the cooperation of the limiting section 731 and the insertion hole 65 in the specific embodiment has better limiting strength and better anti-damage performance. The opening position of one through hole 5 is higher than that of the other through hole, which is to adapt to the height difference caused by the stacking of the two limiting sheets 73, so that the limiting sheet 73 has better locking and fitting accuracy when moving.

[0039] Furthermore, by setting the plug sleeve assembly 62 and the bottom sleeve assembly 61 which are inserted into each other, the contact stress intensity of the torsion spring 64 is increased, the convex sleeve part 2 is integrally formed on the handle base 1, so that the overall anti-damage strength is higher, and the convex sleeve part 2 is integrally formed on the handle base 1, which is more convenient for installing the linkage rod 71.

[0040] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
