Specific embodiments: manufacture each component of the utility model according to each accompanying drawing, and assemble the utility model. As can be seen from FIGS. 1 and 2 , the safety tongue body 15 - 1 of the safety tongue assembly 15 is installed in the safety tongue hole 11 of the backing plate 2 . The rear end of the insurance tongue body 15-1 is connected to the insurance tongue plate 15-2, and the rear end of the insurance tongue plate 15-2 is connected to the return spring 15-4, and the rear end of the return spring 15-4 is connected to the insurance plate stopper 15- 5 on. The insurance tongue column head 15-3 is vertically assembled on the bottom of the insurance tongue plate 15-2, and the inner end surface of one side of the "7"-shaped safety plate 18 connected to the pin 7 on the bottom surface of the lock body is tightly attached to the insurance tongue plate column head 15. -3 on. When someone picks the lock with a mechanical plug-in, at first the safety tongue 15-1 will be pried, and at this moment the safety tongue 15-1 will advance into the lock body 1 along the safety tongue hole 10, and the safety tongue plate 15-2 will also move towards the lock body. Body 2 retracts. At this time, the safety plate 18 closely attached to the insurance tongue stigma 15-3 will fall into the reversing hole of the deadbolt body 9-1 along with the advancement of the insurance tongue stigma 15-3. 19 miles, so that the front end of the safety piece 18 bears against the rear end surface of the deadbolt body 9-1, effectively preventing the deadbolt body assembly 9 from moving in translation in the lock body 1, so that the lockset is in a locked state, and the door is not closed. Be opened, and insurance sheet 18 has just played the effect of insurance tamperproof. After the external force disappeared, the safety tongue 15-1 bounced off because the return spring 15-4 at its rear end was not compressed, and the safety tongue 15-1 was released to the outer end of the safety tongue hole 10 again. Because the reversing block 16 is vertically connected on the reversing spring 17 on the bottom side of the lock body 1 . The reversing piece 16 stretching out in the reversing hole 19 generally prevents the dead bolt 9-1 from turning to under normal conditions of use. When the reversing block 16 is pushed down until its upper end leaves the space of the reversing hole 19, at this moment, the deadbolt body 9-1 can be pushed into the reversing hole 19 completely with fingers, because the deadbolt body 9-1 It is movably connected with the deadbolt body connecting rod 9-2, and the deadbolt body 9-1 can rotate 360° at the front end of the deadbolt body connecting rod 9-2, so the deadbolt body 9-1 can be easily exchanged by 180 degrees. °, thereby changing the direction of opening the door, which is very convenient. After commutation is finished, promote reversing block 16 with finger, make its front end face get back in reversing hole 19 again, can stop dead bolt body 9-1 from changing direction. The functions and operations of other components are the same as those of general mortise locks, so there is no need to describe them. In general, the utility model is flexible and convenient, and has good safety performance.
