A square shaft 34 is provided at the center of the rotary shaft 28 of the interior handle 29, the rotary shaft 28 is fitted into the bearing hole 3 of the case 1, and the square shaft 34 is the cam 13. After passing through the square hole 33, the fixing pin 31 is inserted into the fixing pin recess 32 to prevent the indoor handle 29 from escaping.

In addition, a cover 6 having a connecting pillar 8 having a length equal to the thickness of the bathroom door and having a shaft hole 7 through which the square shaft 34 penetrates is provided with a screw fastening hole 4 and a screw ( 5) are combined.

The handle fixing plate 16 having the shaft hole 18 and the screw through hole 17 is coupled to the cover 22 through the connecting column 8 and the screw through hole 17, and the display panel 20. The square shaft coupling hole 19 is attached to the tool shaft 21 is coupled to the square shaft 34 through the shaft hole 18, and has a tool groove through hole 27 and a display window 30. The outdoor handle 26 having a handle formed at the bottom thereof is covered with the handle fixing plate 16, and then the screw 25 is coupled through the screw hole 24.

The present invention configured as described above rotates the indoor handle 29 to one side so that the cam 13 and the square shaft coupling hole 19 fitted to the square shaft 34 rotate.

As the cam 13 rotates, the cam protrusion 14 pushes the cam catching protrusion 12 to one side, and the slider 33 moves so that the locking pin 11 protrudes out of the locking pin entrance 2 so that the locking pin 11 is opposite. The locking pin 11 is caught in the locking hole 35 to lock the door.
