when the limit switch is in a closed state, the limit switch is matched with the limit bulge to limit the rotation of the limit ring to exceed a first angle,
when the limiting switch is in an on state, the limiting switch and the limiting protrusion are matched to limit the rotation of the limiting ring to exceed a second angle.
11. The escape structure for a push-button combination lock as claimed in claim 1, wherein:
the reset assembly comprises a torsion spring arranged between the mounting cavity and the knob, a push rod spring arranged between the end part of the sliding groove and the push rod, and a locking plate spring arranged between the lock seat and the locking plate.
12. The escape structure for a push-button combination lock as claimed in claim 1, wherein:
the notch comprises a key abdicating groove and a button abdicating groove which are arranged side by side, and the periphery of the bottom end of the button is provided with a limiting flange;
when the lock plate is at an initial position, the key abdicating groove allows the button to drive the password key to be pressed down, and the lock plate blocks the limiting flange to limit the button to be pressed down to a code changing height;
when the locking plate faces the knob and moves, the button abdicating groove allows the button to drive the password key to be pressed down to the code changing height.
