[0020] See also Figures 1 to 4 In an embodiment of the utility model, a plastic buckle for preventing falling off includes a fixed buckle 1, a fixed belt 2 is fixedly connected to the bottom of the fixed buckle 1, a movable buckle 4 is arranged on the top of the fixed buckle 1, a movable belt 5 is fixedly connected to the top of the movable buckle 4, a clamping groove 9 is opened at the bottom of the fixed buckle 1, the bottom of the fixing belt 2 is plugged and connected to the clamping groove 9, and movable arms 6 are arranged on the top of both sides of the clamping groove 9 of the fixed buckle 1, and the two movable arms 6 are respectively fixedly connected to the first clamping block 7 at one end close to the movable buckle 4, and the movable buckle 4 is respectively fixedly connected to the second clamping block 8 at the side walls of the two ends of the movable arm 6.

[0021] Preferably, in the present embodiment, the first clamping block 7 and the second clamping block 8 are both arranged in a fan-shaped structure, and the arcs of the plurality of first clamping blocks 7 are arranged toward the top, and the arcs of the plurality of second clamping blocks 8 are arranged toward the bottom, so that through the arc-shaped cooperation setting of the first clamping block 7 and the second clamping block 8, when the movable buckle 4 is plugged into the fixed buckle 1, the movable arm 6 can be stretched out through the coordinated use of the arc surfaces of the first clamping block 7 and the second clamping block 8 to ensure that the movable buckle 4 can be normally plugged into the fixed buckle 1, and the limit spring 12 cooperates with the rotating shaft 11 to drive the movable arm 6 to reset, and the movable buckle 4 and the fixed buckle 1 are limited by the plane limitation of the first clamping block 7 and the second clamping block 8 to prevent the movable buckle 4 from falling off and improve the connection stability.

[0022] The tops of the fixing buckle 1 on both sides of the clamping groove 9 are provided with connecting grooves 10 . The tops of the two connecting grooves 10 are both through-opened, and the bottoms of the two movable arms 6 are both inserted and connected to the connecting grooves 10 .

[0023] Preferably, the connection and activity space of the movable arm 6 is provided through the connecting groove 10, thereby ensuring the movement of the movable arm 6. At the same time, in this embodiment, the outer diameter of the movable arm 6 is smaller than the width inside the connecting groove 10, ensuring that the movable arm 6 can swing to a certain extent in the connecting groove 10.

[0024] The side walls of the two movable arms 6 located inside the connection groove 10 are fixedly connected with the rotation shaft 11 , and one end of the plurality of rotation shafts 11 away from the movable arms 6 is rotatably connected to the inner wall of the connection groove 10 .

The ends of the two limit springs 12 away from the movable arms 6 are fixedly connected to the inner wall of the connecting groove 10.

[0026] Preferably, in this embodiment, the movable arm 6 can be automatically reset by the limit spring 12, so that the movable buckle 4 is locked by the cooperation of the first clamping block 7 and the second clamping block 8. When the movable arm 6 swings, its swinging effect is ensured by the rotating shaft 11, and the movable arm 6 is connected and limited at the same time.

[0027] Release buttons 3 are provided on both side walls of the fixing buckle 1. The two release buttons 3 are movably connected to the fixing buckle 1. One end of the two release buttons 3 facing the connecting groove 10 is fixedly connected to the side wall of the movable arm 6 with matching position.

[0028] The two release buttons 3 are both arranged between the rotating shaft 11 and the limiting spring 12 .

[0029] Preferably, when the movable buckle 4 needs to be released, it is only necessary to press the release buttons 3 on both sides at the same time, driving the movable arm 6 to squeeze the limit spring 12, thereby driving the top of the movable arm 6 to swing, driving the first block 7 away from the second block 8, thereby releasing the limit of the first block 7 and the second block 8.

[0030] The working principle of the utility model is: when using the device, it is only necessary to insert the movable buckle 4 into the clamping groove 9. When inserted, the arc surfaces of the two second clamping blocks 8 and the first clamping block 7 contact each other, and the movable arm 6 is stretched open to ensure that the movable buckle 4 can be smoothly inserted into the clamping groove 9.

[0031] When the movable buckle 4 is inserted into the clamping groove 9, the planes of the first clamping block 7 and the second clamping block 8 are interlaced with each other, so as to limit the movable buckle 4 and the fixed buckle 1 and improve the connection strength.

[0032] When the movable buckle 4 needs to be released, it is necessary to press the release buttons 3 on both sides at the same time, driving the movable arm 6 to squeeze the limit spring 12, and cooperate with the rotating shaft 11 to drive the top of the movable arm 6 to swing, thereby releasing the limit of the first clamping block 7 and the second clamping block 8. At this time, the movable buckle 4 can directly disengage from the clamping slot 9, completing the release of the movable buckle 4 and the fixed buckle 1.

[0033] When releasing, the two release buttons 3 need to be pressed simultaneously, and the first card block 7 and the second card block 8 can be released only after being pressed to a certain extent, thereby improving the anti-falling effect.
