More than one screw hole is arranged on the base plate 1 among the figure, can pass through screw 20, be fixed on the door and window.Base plate 1 also inserts in the oblong aperture of upper shell 2 ends by the flange 23 of one end, fixedlys connected with the other end of upper shell 2 by the screw 22 that is through in 1 liang of side flanging hole of base plate.Shank 3 is positioned at base plate 1 and upper shell 2 formed cavitys, and can stretch out from an end of upper shell 2 and withdraw.The flexible of shank 3 is by shank connecting plate 4, handles claw-plate 7, control handwheel 5 and latch handle ring 13 and controls, and shank connecting plate 4 is connected with shank 3 by rivet 15.The upper overturning of shank connecting plate 4 both sides has long through groove, crosses the pin 14 of riveting in upper shell 2 both sides in the groove.Pin 14 can only move forward and backward shank connecting plate 4.And can in upper shell 2, not come off, off-centre has been riveted operated pawl 8 on the manipulation claw-plate 7, and operated pawl 8 is inserted in the horizontal elongated hole 24 of shank connecting plate 4 ends.Handling claw-plate 7 is connected with control handwheel 5 by screw 21.Control handwheel 5 usefulness circlips 6 are stuck in the groove of control handwheel itself and are connected with housing 2.And it is removable.Latch handle ring 13 is loaded in the swallow tail shaped slot 25 of control handwheel 5.The two ends of latch handle ring 13 also are turbination, so that latch handle ring 13 can not deviate from from control handwheel 5 under the effect of lateral force.During use, after rotating latch handle ring 13, control handwheel 5 rotates thereupon, and the operated pawl dish 7 that is fixed on the control handwheel 5 also rotates, and the manipulation melon 8 that off-centre is fixed in operated pawl dish 7 just moves by circular path.Because operated pawl 8 is inserted in the horizontal groove of shank connecting plate 4.So when operated pawl 8 circular motion, just force the shank plate to move forward and backward, thereby realize the flexible of shank.Locking mechanism is made up of susceptor pin 9, flexure strip 10, locking plate 11 and lock core 12.Susceptor pin 9 is through in the hole, garden of base plate 1, and removable.Flexure strip 10 is placed in the bottom of susceptor pin 9, and locking plate 11 and lock core 12 all are placed in the corresponding profile position of susceptor pin 9 with the non-circular hole on it.Oval locking plate 11 is arranged in the groove in the middle of the shank connecting plate 4, and the shape of groove is the mute tinkling of pieces of jade shape of two circle intermediate elongated.Because when locking plate 11 was positioned at groove intermediate elongated section, the major axis of oval locking plate 11 was parallel with the groove elongated segment, shank connecting plate 4 can move forward and backward.And horizontal among the circular portion of groove one end the time when the major axis of locking plate 11, be wider than the elongated segment part of groove because of the major axis of locking plate 11, so shank connecting plate 4 just can not move, latch is promptly locked, the rotation of locking plate 11 is controlled by the key that inserts lock core.Lock core is right and wrong garden profile also, and consistent with profile in the key.
