A projection 61 of the locating pin 6 is fitted inside the groove 51 of the reset block 5, and has a limiting role on the reset block 5 when rotating. The gear 31 of the reset block 3 engages with the gear 11 of the clutch 1, thus realizing the transmission function between the reset block 3 and the clutch 1.

Abstract: A left and right interchanging device for a lock clutch includes a clutch pin, an inner rotary clutch shaft, and an outer rotary clutch shaft. The clutch pin is movably placed in a hole of the inner rotary clutch shaft and connected with a built-in driving module of the inner rotary clutch shaft. The module controls the clutch pin so that the clutch pin can retract into or extend out of the inner rotary clutch shaft. The inner rotary clutch shaft is placed in a central hole of the outer rotary clutch shaft, and both can rotate about a same central axis. A first stop edge and a second stop edge are provided on the inner rotary clutch shaft and connected with a driving output shaft. A third stop edge and a fourth stop edge are provided on the outer rotary clutch shaft and connected with a driving output and input shaft. When a door is left-opened, the third stop edge correspondingly contacts the clutch pin and the fourth stop edge correspondingly contacts the second stop edge.

Abstract: A differential linkage attachment of handles includes a first handle ring and a second handle ring placed on right and left sides, respectively, and set in a rectangular dead bolt shifting block independently. An end of the second handle ring is encircled with a first slanted latch bolt shifting plate, and an end of the first handle ring is encircled with a second slanted latch bolt shifting plate. All of the five parts turn around on a center axis. When the second handle ring turns forward or clockwise, the rectangular dead bolt shifting block or the first slanted latch bolt shifting plate is linked to turn around on the center axis independently, and when the first handle ring turns clockwise, the rectangular dead bolt shifting block or the second slanted latch bolt shifting plate is linked to turn around on the center axis independently.

Abstract: The present invention discloses a clutch and reverse-locking device comprising a stop bolt (1), an internal clutch stem (2), a clutch control member (3), a clutch casing (4) and a stopper (5). The internal clutch stem (2) is inserted into the clutch casing (4) and they move independently of each other. The internal clutch stem (2) has a slot (21) to house and guide the stop bolt (1). The clutch control member (3) is installed in the internal clutch stem (2) and has an edge (42) set against the groove (11) of the stop bolt (1). The stopper (5) is fitted in the internal clutch stem (2) and protrudes partially outward therefrom. The protruding or non-protruding position of the stop bolt (1) in the internal clutch stem (2) correlates or disconnects the joint movement of the clutch casing (4) and the internal clutch stem (2), activating or deactivating the clutch operation of the clutch device.
