The working process of the invention is as follows: in the state shown in fig. 3, the toggle head 072 is moved upwards, the limit head 071 of the reversing plate 07 is separated from the limit groove 051, at this time, according to the door mounting direction, the handle 03 is rotated to a required side slightly more than 90 degrees, the toggle head 072 is loosened, the reversing plate 07 is acted by the tension of the reset spring 08, the limit head 071 falls into the limit notch 057, the handle 03 is loosened again, the reset toggle piece 06 is acted by the tension of the reset spring 08, so that the lug 056 abuts against the limit head 071, namely, the handle is always in a horizontal state when only being under the spring force, the quick reversing action of the handle is completed, and in the reversing process, the spring hook of the reset spring 08 connected with the spring hanging arm 061 of the reset toggle piece 06 can move one end position of the spring hanging arm 061 from the middle position of the spring hanging arm 061 in an unobstructed manner, as shown in fig. 2 and 4; as shown in fig. 4, the protrusion 056 abuts against the protrusion 121, and the handle 03 is rotated counterclockwise and downward, that is, the first shift shaft 05 fixed with the handle is rotated counterclockwise, and the first shift shaft 05 pushes the second shift shaft 12 to rotate counterclockwise, so as to unlock each lock point of the lock body.

As shown in example fig. 4, when the inner safety knob 09 is rotated, the inner safety pulling piece 10 rotates clockwise, the driving hole 102 drives the pin 131 to move, that is, the unlocking plate 11 moves upwards, the protruding block 113 is abutted against the pin 132, and the inner safety knob 09 is driven by the torsion spring in the lock body to push the unlocking plate 11 to be abutted against and finally located at the upper safety end position; at this time, the handle 03 is rotated anticlockwise downwards, the pin 131 on the reset pulling piece 06 abuts against and pushes the unlocking plate 11 to move downwards, when the handle 03 rotates for a certain angle, the inner safety knob 09 is accelerated to rotate anticlockwise under the action of the torsion spring in the lock body, that is, the unlocking plate 11 is pulled to move downwards to the initial state of unlocking, the handle 03 is rotated anticlockwise continuously, that is, the pulling shaft one 05 continues to push the pulling shaft two 12 to rotate anticlockwise, and unlocking actions on all lock points of the lock body are completed.

If the outer handle is unlocked, the second shift shaft 12 rotates along with the outer handle, and also under the view angle of fig. 4, the second shift shaft 12 rotates anticlockwise, and the originally contacted bump 056 and bump 121 are separated, that is, the rotation of the second shift shaft 12 does not cause linkage of the inner handle, that is, the independent action performance of the inner handle and the outer handle is realized.

The foregoing description is merely illustrative of the present invention and is not intended to limit the invention in any way, and it will be apparent to those skilled in the art that various modifications, substitutions and alterations can be made without departing from the technical scope of the invention.
