Belt buckle

Abstract

The present invention provides a belt buckle, which solves the problem that the existing self-locking belt buckle is easy to be inconvenient to unlock when it is locked over tightly. The belt buckle comprises a main-body; a plate-control body; and a pawl for restricting the position of the belt-body; wherein the rear end of the main-body is set with a belt-body clamping section, the front end of the main-body is rotatedly connected with a rotation-shaft, a vice placing hole is set in the front end of the plate-control body, a groove is set on the outer surface of the front end of the main-body, and a position-restoring spring is set between the rear end of the pawl and the rear end of the bottom of the groove. The present invention can adjust the tightness of the belt by just pressing, the adjustment is convenient and the flexibility is higher.
