[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model. Embodiment

[0019] Please refer to Figures 1-3 For this utility model, a technical solution is provided: a plastic spring buckle, which includes a pressing body 1, an inserting column body 2, a trapezoid body 3, a clamping body 4 and a spring body 5. The bottom of the pressing body 1 is fixedly connected to the inserting column body 2. The bottom of the inserting column body 2 is fixedly connected to the trapezoid body 3. On both sides of the top of the trapezoid body 3, clamping bodies 4 are fixedly arranged. The clamping bodies 4 are connected to the bottom of the inserting column body 2. Groove holes 6 are symmetrically formed on the surface of the trapezoid body 3. A spring body 5 is arranged between the trapezoid body 3 and the pressing body 1.

[0020] Furthermore, since the clamping body 4 is arranged between the inserting column body 2 and the trapezoid body 3, a stable connection effect is formed for the clamping body 4. By adopting the connection method where the head of the clamping body 4 is located outside the bottom of the round hole 9, effective stability is formed during assembly and use, and it is not easy to fall off. At the same time, when the clamping body 4 is extruded through the groove hole 6, it is not easy to break, thereby increasing the service life of the plastic spring buckle. In this embodiment, both the front and back surfaces of the trapezoid body 3 are flat.

[0021] It should be noted that the inserting column body 2 is installed and connected in the round hole 9 where the first mounting plate 7 and the second mounting plate 8 overlap. The diameter of the round hole 9 is larger than the diameter of the inserting column body 2. This facilitates the insertion of the plastic spring buckle to fix two objects. Except for the first mounting plate 7, the second mounting plate 8 and the spring body 5, other parts of the plastic spring buckle are made of PA66 nylon material. Using PA66 nylon material has the advantages of high insulation performance, light weight, not easy to rust and not corroding.

[0022] Secondly, the diameter length of the round hole 9 is smaller than the length of the clamping bodies 4 on both sides of the trapezoid body 3. The clamping bodies 4 are located outside the bottom of the round hole 9. The lower part of the clamping bodies 4 is restricted outside the bottom of the round hole 9. At the same time, through the upper part of the spring body 5 being restricted outside the top of the round hole 9, the plastic spring buckle will not shake and is not easy to loosen.

[0023] Secondly, the top of the clamping body 4 and the bottom of the first mounting plate 7 are on the same horizontal plane, ensuring that after installation, the two materials can be fixed by the clamping body 4 abutting against the bottom of the first mounting plate 7.

[0024] In addition, the spring body 5 is sleeved on the surface of the inserting column body 2. The diameter of the spring body 5 is larger than the diameter of the round hole 9 and smaller than the diameter of the pressing body 1, ensuring that the spring body 5 is located on the top of the second mounting plate 8, so that the materials can be fixed by the way of upper and lower abutment.

[0025] When the present utility model is specifically implemented: when using the plastic spring buckle, first place the first mounting plate 7 and the second mounting plate 8 together, and align the corresponding round holes 9. Secondly, insert the bottom of the plastic spring buckle through and into the inside of the round hole 9 until the trapezoid body 3 and the clamping body 4 are exposed. At this time, a sound similar to a click will occur. At the same time, the plug column body 2 will enter the inside of the round hole 9, and the clamping body 4 will abut against the bottom of the first mounting plate 7. The round hole 9 squeezes the spring body 5, and the bottom of the spring body 5 abuts against the top of the second mounting plate 8, so that the two mounting plates can be quickly fixed in this way. When disassembly is required, the staff only needs to hold the top of the trapezoid body 3 with their hand. Under the action of the slot hole 6, the clamping bodies 4 on the left and right sides will contract inward. When the total length of the clamping bodies 4 on the left and right sides that are fixedly clamped is less than the diameter of the round hole 9, then hold the pressing body 1 and lift it upward, and the plastic spring buckle can be quickly disassembled.

[0026] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
