It can be connected to the electronically controlled transmission 9 via an open signal, and can be driven to rotate clockwise (as shown in FIG. 3), and the pin 942 can be slid into the spring 96 from the first bent portion 961 of the spring 96. The spiral groove 963, because the rotation direction of the spring 96 is restricted, the clutch member 95 is brought close to the position of the first buckle 943 by the position adjacent to the second buckle 944, so that the protrusion 9511 is located at the position The groove 811 of the outer drive tube 81 slides and moves to a position at which the first groove 832 of the sleeve 83 is engaged, wherein when the pin 942 is located within the spiral groove 963, the rotation is located adjacent to the first member 951. When the through hole 9512 is rotated to the through hole 9521 of the second member 952, if the rod member 93 continues to rotate, the pin 942 will slide out from the second bent portion 962 of the spring 96, and the pin of the rod member 93 942 is formed idling, the clutch member 95 is no longer actuated, and at this time, the outer handle 5 is rotated to drive the outer drive a tube 81, the outer driving tube 81 can drive the protrusion 9511 and the sleeve 83 to rotate, thereby driving the transmission portion 831 of the sleeve 83 to drive the driving seat 13 to pull the internal driving component of the latch 6 (not shown) The latching head 61 is actuated to position the lock body in an unlocked state; when the outer handle 5 is released, the drive base 13 is returned to the original position by the restoring force of the two elastic members 16, and the lock is activated at this time. The internal drive member (not shown) of the latch 6 also returns to its original position due to the action of the internal resilient member, allowing the latch head 61 to be in the extended position.

As shown in FIG. 1 , when it is necessary to open the door inside, only the inner handle 4 needs to be rotated, and the two transmission portions 711 of the inner driving tube 71 can be driven to drive the driving seat 13 to pull the internal driving component of the latch 6 (not shown). Actuating the latch head 61 such that the latch head 61 is in the retracted position, and when the inner handle 4 is released, the drive seat 13 is returned to the original position by the restoring force of the elastic member 16, The internal drive member (not shown) of the latch 6 also returns to its original position due to the action of the internal resilient member, allowing the latch head 61 to be in the extended position.

As shown in FIG. 1, the lock body of the present invention has a lock set 51 which can directly drive the sleeve 83 by means of a key (not shown), thereby driving the transmission portion 831 of the sleeve 83. The driving seat 13 pulls an internal driving component (not shown) of the latch 6 to actuate the latching head 61 to position the latching head 61 in a retracted position; and in order to adapt the lock body to various different The place, therefore, the creation can also be applied to the lock body that does not match the lock set 51, which are not described herein.

However, the above-mentioned sections of the present invention are only preferred embodiments of the present invention, and are not intended to limit the implementation of the present invention, and are generally based on the structural features and spirit described in the following patent application scope.
