Claims (1)

[Scope of utility model registration request] In response to the rotational force of the knob 2, the dead bolt 4 moves in and out of the window hole 5 of the main body 1, and engages the engagement hole 21a of the arm 21 slidably pivoted to the receiver 23, the engagement hole, the receiver, and the frame 20.
A deadbolt operating mechanism of a safety lock which is configured to removably engage with the engagement holes 23a and 20a of the body, and which is slidable in the main body in a direction substantially perpendicular to the direction in which the deadbolt extends and retracts. Deadbolt cam 11 and valve plate 13
, the deadbolt cam fits between its guide walls 6 and 7 so as to be able to move with the putbolt, while the guide plate fits in the recess 10 of the main body.
The above-mentioned A safety lock which is brought into elastic contact with an eccentric shaft, and has at least two grooves 12, 12' provided at the lower edge of the deadbolt cam which can be releasably engaged with both of the eccentric shafts. deadbolt actuation mechanism.
