An upward convex trapezoidal matching belt is arranged at the upper end of the convex part, and a matching groove with the same shape as the trapezoidal matching belt is opened on the channel;

[0005] A circular ring groove is opened below the spring body, a shaft that can rotate along the circular ring groove is arranged on the circular ring groove, a connecting rod extending outwards is arranged on one side of the shaft, a buckle is arranged on the connecting rod, and a clamping groove matched with the buckle is arranged above the spring body.

[0006] In the above-mentioned special-shaped compression spring convenient for storage, the upper end of the matching convex inclines downward along the spiral line of the spring body from the port above the spring body, and the upper part of the buckle groove inclines upward along the spiral line of the spring body from the port below the spring body.

[0007] In the above-mentioned special-shaped compression spring convenient for storage, one side of the buckle is arc-shaped and forms a hook shape at the hinge at the port of the buckle, and the shape of the clamping groove is the same as that of the buckle.

[0008] In the above-mentioned special-shaped compression spring convenient for storage, a pull ring for pulling the connecting rod is arranged on the other side of the buckle.

[0009] Compared with the prior art, the special-shaped compression spring that is convenient for storage can fix the spring body in a compressed state through the cooperation of the convex part and the groove after compression, and then realize locking through the cooperation of the buckle and the card slot, reducing the space occupation and facilitating transportation.

[0013] The following are specific embodiments of the present invention and in combination with the drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0014] As Figure 1 , Figure 2 shown, the special-shaped compression spring that is convenient for storage includes a spring body 1. A channel 2 is opened at the port below the spring body 1. Open slots 3 are opened on both sides of the channel 2. A convex part 4 that cooperates with the channel 2 is provided at the port above the spring body 1. Matching convexes 5 that cooperate with the matching groove 7 are provided on both sides of the convex part 4. An upward convex trapezoidal matching band 6 is provided at the upper end of the convex part 4. A matching groove 7 having the same shape as the trapezoidal matching band 6 is opened on the channel 2;

[0015] A ring groove 8 is opened below the spring body 1. A shaft 9 that can rotate along the ring groove 8 is provided on the ring groove 8. A connecting rod 10 extending outward is provided on one side of the shaft 9. A buckle 12 is provided on the connecting rod 10. A card slot 11 that cooperates with the buckle 12 is provided above the spring body 1.

[0016] The upper end of the matching convex 5 inclines downward along the spiral line of the spring body 1 from the port above the spring body 1. The upper part of the card slot 11 inclines upward along the spiral line of the spring body 1 from the port below the spring body 1.

[0017] One side of the buckle 12 is arc-shaped and forms a hook shape at the hinge at the port of the buckle 12. The shape of the card slot 11 is the same as that of the buckle 12.

[0018] During use, first compress the spring body 1, and move the port above the spring body 1 below the port below the spring. Insert the convex portion 4 into the channel 2, and at the same time slide the mating convex 5 into the mating groove 7. The trapezoidal mating band 6 is used to facilitate the entry of the convex portion 4 into the channel 2. Then rotate the connecting rod 10 to align the buckle 12 with the buckle 12 and insert it to complete the locking.

[0019] To elaborate further, a pull ring 13 for pulling the connecting rod 10 is provided on the other side of the buckle 12.

[0020] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0021] Although terms such as spring body 1, channel 2, opening groove 3, convex portion 4, mating convex 5, trapezoidal mating band 6, mating groove 7, circular ring groove 8, shaft 9, connecting rod 10, buckle 12, card slot 11, pull ring 13, etc. are used more frequently in this article, the possibility of using other terms is not excluded. Using these terms is only for more conveniently describing and explaining the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
