[0026] Specifically;

[0027] In this embodiment, as shown in the attached Figure 1 , 2 As shown, the anti-deflection connection structure includes two groups of anti-deflection plates 5, one group of anti-deflection plates 5 is installed on the upper surface of the support plate 4, and the other group of anti-deflection plates 5 is installed on the lower surface of the bolster 2, and the number of each group of anti-deflection plates 5 is set to be several, and the spring assembly 3 is composed of several springs, and the top and bottom ends of each spring are respectively located at the bottom of the bolster 2 and the surface of the support plate 4, and are located between multiple anti-deflection plates 5.

[0028] Specifically, the top and bottom ends of the spring are respectively located between a plurality of anti-deflection plates 5, and the plurality of anti-deflection plates 5 can block the spring and ensure that the spring will not be laterally deflected during operation.

[0029] In this embodiment, as shown in the attached Figure 2 , 5 As shown, the cross-sectional shape of the anti-deflection plate 5 is set to be L-shaped, and threaded holes are provided at the connection between the anti-deflection plate 5 and the support plate 4 and at the connection between the anti-deflection plate 5 and the bolster 2, and bolts 8 are provided on the internal threads of the threaded holes.

[0030] Specifically, the anti-deflection plate 5 can be disassembled and installed by means of the bolts 8, which will not hinder the operation and inspection of the spring assembly 3. The maintenance operation is convenient for disassembly and installation, and the operation is safe and reliable.

[0031] In this embodiment, as shown in the attached Figure 2 , 3 As shown, a folding and unfolding assembly 6 is arranged between two anti-deflection plates 5 distributed up and down, and the folding and unfolding assembly 6 includes a plurality of cross-arranged first folding and unfolding plates 60 and a plurality of cross-arranged second folding and unfolding plates 61.

The plurality of second folding and unfolding plates 61 are rotatably connected at the end and the middle.

[0032] Specifically, the retractable and deployable component 6 is installed between the two anti-deflection plates 5. When the spring is in operation, the retractable and deployable component 6 can follow the operation of the spring and retract and deploy, thereby reducing the impact on the operation of the spring.

[0037] Furthermore, a retractable assembly 6 is provided between the two anti-deflection plates 5. The retractable assembly 6 is composed of a plurality of cross-arranged first retractable plates 60 and a plurality of cross-arranged second retractable plates 61, which can realize cross-rotation. Thus, the retractable assembly 6 can freely retract and retract along with the operation of the spring while connecting the two objects. Thus, once the spring breaks or the spring bolt 8 fails, mechanical injury accidents caused by the flying out of the spring-related components can be reduced.
