An autolock buckle operates without traditional belt holes, instead, the strap typically features a hidden track or a series of tiny teeth on its underside.

Locking Mechanism : The buckle itself contains a simple clamping device with small “teeth” that engage with this track. To secure the belt, you simply slide the strap through the buckle until you achieve your desired fit.

Unlocking Mechanism: You usually press a small lever or button on the buckle, which disengages the locking teeth, allowing the strap to slide freely.
