[0039] There are two upper triangular plates 3, which are respectively fixedly connected to the angles on both sides of the transverse part and the longitudinal part of the upper half pipe 1;

[0040] There are two lower triangular plates 4, which are respectively fixedly connected to the angles on both sides of the transverse part and the longitudinal part of the lower half pipe 2;

[0041] The lower triangular plate 4 and the upper triangular plate 3 on the same side fit each other and are clamped together by the elastic clamping structure 5. The clamping and fixing here is stronger than the clamping and fixing at the edge of the connection.

[0045] The gap width between the two parts of the elastic clamping structure 5 is proportional to the depth of the clamping reinforcement 7 screwed into the internal thread 6; as the screwing depth of the clamping reinforcement 7 increases, the gap width between the two parts of the elastic clamping structure 5 increases, making the strength of the clamping and fixing of the lower triangular plate 4 and the upper triangular plate 3 on the same side of the elastic clamping structure 5 higher.

[0046] In some embodiments, in order to allow the arc-shaped elastic metal sheet 52 to be squeezed and deformed into the reserved through hole on the upper surface of the upper triangular plate 3, the elastic clamping structure 5 is stably clamped at the upper edge of the reserved through hole on the upper surface of the upper triangular plate 3 by the stretched conical semi-tubes 51 of the elastic metal on both sides and the arc-shaped elastic metal sheet 52. The elastic clamping structure 5 includes:

[0047] The elastic metal conical half cylinder 51 is symmetrically distributed on the left and right, and the lower ends of the two elastic metal conical half cylinders 51 are fixedly connected to the middle of the upper surface of the lower triangular plate 4.

The lower edge of the outer wall of the arc-shaped elastic metal sheet 52 abuts against the upper edge of the reserved through hole on the upper surface of the upper triangular plate 3 for clamping.

[0053] In some embodiments, in order to increase the elastic coefficient of the arc-shaped elastic metal sheet 52, so that the arc-shaped elastic metal sheet 52 can be more firmly clamped on the upper edge of the reserved through hole on the upper surface of the upper triangular plate 3, the arc-shaped elastic metal sheet 52 is laterally fixedly connected to one end of an elastic rod on one side of the conical semi-cylinder 51 close to the elastic metal, and the other end of the elastic rod is against the outer wall of the conical semi-cylinder 51 on the same side. The elastic rod is made of the same material as the arc-shaped elastic metal sheet 52 and can be deformed together with the raised middle part of the arc-shaped elastic metal sheet 52.

[0054] In some embodiments, in order to open the two parts of the elastic snap-fit ​​structure 5 so that the elastic snap-fit ​​structure 5 is better snap-fitted to the upper edge of the reserved through hole on the upper surface of the upper triangular plate 3, the snap-fit ​​reinforcement member 7 includes:

[0056] An elastic clamping structure 5 extends from the upper end of the cylinder 71. Grasping and rotating the cylinder 71 can drive the external thread block 72 to be screwed on the internal thread 6. As the thread block 72 is screwed in, the conical half cylinder 51 and the arc-shaped elastic metal sheet 52 with elastic metal on both sides can be stretched open.

[0057] In some embodiments, in order to prevent slipping and facilitate the rotation of the cylinder 71 , anti-slip grooves 73 are evenly formed on the upper end of the outer wall of the cylinder 71 .

[0058] In some embodiments, in order to limit the downward screwing depth of the cylinder 71 , a limiting ring 74 is integrally formed at the middle of the outer wall of the cylinder 71 , and the limiting ring 74 is located above the elastic clamping structure 5 .

[0059] In some embodiments, in order to further ensure the firmness of the lower end of the outer wall of the arc-shaped elastic metal sheet 52 being clamped at the upper edge of the reserved through hole on the upper surface of the upper triangular plate 3, a clamping block 8 is welded to the lower end of the outer wall of the arc-shaped elastic metal sheet 52, and the lower end of the clamping block 8 is against the upper edge of the reserved through hole on the upper surface of the upper triangular plate 3.

[0063] Working principle:

[0064] The lower triangular plate 4 and the upper triangular plate 3 on the same side fit together and are clamped together by an elastic clamping structure 5. The clamping and fixing here has higher strength than the clamping and fixing at the edge of the connection. The gap between the two parts of the elastic clamping structure 5 forms a conical cavity, and an internal thread 6 is provided in the middle of the inner wall of the conical cavity. A clamping reinforcement piece 7 is screwed on the internal thread 6 at its lower end. As the screwing depth of the clamping reinforcement piece 7 increases, the gap width between the two parts of the elastic clamping structure 5 increases, so that the strength of the clamping and fixing of the lower triangular plate 4 and the upper triangular plate 3 on the same side by the elastic clamping structure 5 is higher.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
