[0019] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0020] Reference Figures 1-6 As shown, a belt buckle that is convenient for adjusting the tightness of the belt includes a belt buckle body 1, a connecting seat 2, a reset device 3, and a clamping block 4. The belt buckle body 1 is provided with a pair of connecting arms 11 arranged opposite to each other, and the pair of connecting arms 11 are vertically arranged on the inner side surface of the belt buckle body 1, the connecting seat 2 is rotatably connected to the connecting arms 11, the connecting seat 2 is located between the pair of connecting arms 11, the reset device 3 is arranged between the connecting seat 2 and the connecting arms 11, the reset device 3 is used to restore the belt buckle body 1 to a position parallel to the connecting seat 2, the clamping block 4 is arranged at the front end of the connecting seat 2, and the top of the clamping block 4 cooperates with the inner side surface of the belt buckle body 1 to clamp and fix the belt on the inner side surface of the belt buckle body 1, so that the belt can be fixedly connected to the belt buckle body 1 without punching. Therefore, the user can fine-tune the tightness of the belt to achieve the most comfortable tightness.

[0021] A rotating device 5 is provided between the connecting base 2 and the connecting arm 11, and the belt buckle body 1 is rotatably connected to the connecting base 2 via the rotating device 5. The rotating device 5 includes a first rotating hole 51, a second rotating hole 52, and a rotating shaft 53. The first rotating hole 51 is provided at the front end of the connecting base 2, the second rotating hole 52 is provided on the connecting arm 11, and the rotating shaft 53 passes through the first rotating hole 51 and the second rotating hole 52. Specifically, the rotating shaft 53 is fixedly connected to the first rotating hole 51, and the belt buckle body 1 can rotate around the rotating shaft 53.

[0022] A mounting groove 21 is provided at the front end of the connecting base 2 . The mounting groove 21 is U-shaped. The pressing block 4 is located in the mounting groove 21 , and the pressing block 4 is fixedly disposed on the rotating shaft 53 .

[0023] The pressing block 4 is made of rubber material and includes a main body 41 and a pressing portion 42. The main body 41 is disposed on the rotating shaft 53, and the pressing portion 42 is disposed on the main body 41. The pressing portion 42 is arranged toward the inner side surface of the belt buckle body 1 and is used to cooperate with the inner side surface of the belt buckle body 1 to fix the belt on the inner side surface of the belt buckle body 1. Specifically, the distance between the top of the pressing part 42 and the inner side surface of the belt buckle body 1 is the shortest, and the shortest distance is less than the thickness of the belt. From the top of the pressing part 42 to the bottom of the pressing part 42, the distance between the outer surface of the pressing part 42 and the inner side surface of the belt buckle body 1 gradually increases. Therefore, when the belt buckle body 1 is parallel to the connecting seat 2, the belt buckle body 1 and the belt can be fixed. When the belt buckle body 1 is rotated toward its inner side, the distance between the outer surface of the pressing part 42 and the inner side surface of the belt buckle body 1 increases, so that the belt can be detached from the belt buckle body 1.

[0024] The pressing portion 42 is provided with a plurality of anti-slip grooves 421 , so that the fixation between the belt and the belt buckle body 1 is more secure.

[0025] The reset device 3 includes a reset groove 31 and a reset torsion spring 32. The reset groove 31 is provided on the connecting base 2. The reset torsion spring 32 is sleeved on the rotating shaft 53. The reset torsion spring 32 is located in the reset groove 31. One end of the reset torsion spring 32 is connected to the connecting base 2, and the other end of the reset torsion spring 32 is connected to the connecting arm 11. Specifically, when the user rotates the belt buckle body 1 toward its inner side, the reset torsion spring 32 is compressed. When the user releases the belt buckle body 1, the belt buckle body 1 automatically returns to a position parallel to the connecting base 2 under the action of the reset torsion spring 32.

[0026] The above are only some specific implementation methods of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
