A convex portion is arranged on the lower end surface of the locking body block, the lower end surface of the convex portion is an arc chamfer surface, an anti-inclined angle is formed between the convex portion and the lower end surface of the locking body block, the convex surface is located on the front side surface of the locking body block, and the locking body block, the limiting blocks, the mounting opening, the spring connecting rods, and the rotating shaft are integrally formed. A limiting boss for cooperating with the limiting block is arranged on the lower end surface of the mounting plate and above the limiting block. Two reset springs are respectively arranged within the mounting openings on the two spring connecting rods, and the two reset spring sleeves are respectively sleeved on the two spring connecting rods. One end of the reset spring abuts against the lower end surface of the mounting plate, and the other end of the reset spring abuts against the rear end surface of the locking body block. A limiting disk is arranged at the front end of the rotating shaft, the diameter of the limiting disk is larger than the diameter of the rotating shaft, and a lever is arranged at the rear end of the rotating shaft, and the lever is a waist-shaped lever.

[0010] The further improvement is as follows: The convex portion is an arc-shaped convex portion.

[0011] The further improvement is as follows: A placement slot is opened on the rear end surface of the locking body block, and the other end of the reset spring is in snap-fit with the placement slot.

[0012] The further improvement is as follows: The left end of the mounting plate is rotatably arranged between the two mounting seats through a rotating rod, a connecting jack is arranged at the right end of the mounting plate, corresponding jacks corresponding to the connecting jack are respectively arranged on the two mounting seats, a connecting plug rod is slidably arranged within the connecting jack and the corresponding jack at the left end of the mounting plate, the front and rear ends of the connecting plug rod pass through the corresponding jacks and are located outside the mounting seats, fixing disks are arranged at the front and rear ends of the connecting plug rod, the fixing disks are located outside the mounting seats, and the diameter of the fixing disks is larger than the diameter of the corresponding jacks.

[0013] The further improvement is as follows: Longitudinal sliding holes are opened on the two mounting seats, the rotating shaft is arranged between the two mounting seats and located within the longitudinal sliding holes, and the rotating shaft is in clearance fit with the longitudinal sliding holes.

The locking card is clamped with the card slot of the belt through the convex part at the lower end of the lock body block, and the lower end face of the convex part is an arc chamfer surface, which can reduce damage to the belt.

[0015] Further effect: Through the setting of the placement card slot, the other end of the return spring can be prevented from moving left and right on the rear end face of the lock body block, playing a limiting role for the other end of the return spring.

[0016] Further effect: When the lock body block is located at the card slot position of the belt, the lower convex part of the arc-shaped convex part cooperates with the inside of the card slot. And through the shape and position of the arc-shaped convex part on the lock body block, when part of the belt has an inlaid card slot, the arc-shaped convex part is pressed against the belt by the driving force of the return spring, causing the belt to deform by depression so that the bottom of the arc-shaped convex part cooperates with the card slot. When the card slot of the belt is a groove formed by multiple right-angle blocks, the arc-shaped convex part abuts against the right-angle side of the right-angle block and is thus stuck in the groove. And with the extrusion of the lock body block on the belt, the contact surface between the arc-shaped surface of the convex part and the right-angle side is larger, thereby improving the fixing effect of the lock body block on the card slot of the belt. Through the setting of the arc-shaped convex part, various shapes of belt card slots can be adapted. Description of the Drawings
