The two connecting blocks 2 are both located in the accommodating cavity, and the two fixing sleeves 31 are fixed by a first bolt 34; The fixing sleeve 31 is threadedly connected with a tightening screw 35, the tightening screw 35 is parallel to the structural member 1, the screwed-in end of the tightening screw 35 abuts against a side of the connecting block 2 close to the structural member 1, and a plurality of the tightening screws 35 are provided, and the plurality of tightening screws 35 are circumferentially distributed around the axis of the structural member 1; The fixing sleeve 31 includes two symmetrically arranged sleeve bodies 311, and the two sleeve bodies 311 are locked by a second bolt 312; A spring 36 is provided between the two connection blocks 2, and both ends of the spring 36 are respectively connected to the two connection blocks 2. A plurality of springs 36 are provided, and the plurality of springs 36 are evenly distributed circumferentially with the structural member 1 as the center; The cross-sectional shape of the connecting block 2 perpendicular to the length direction of the structural member 1 matches the cross-sectional shape of the opening 32 perpendicular to the length direction of the structural member 1; By means of the cooperation between the through hole and the structural member 1 and the fittings between the connecting block 2 and the fixing sleeve 31, the positioning of the two structural members 1 perpendicular to the length direction of the structural member 1 is achieved. At the same time, by rotating the jacking screw 35, the connecting block 2 and the fixing sleeve 31 are pushed to move relative to each other, so that the distance gap between the two connecting blocks 2 can be made and the spring 36 can be deformed. When the structural member 1 is subjected to a force along its length direction, the spring 36 continues to be compressed, and buffering is achieved through the elastic force of the spring 36. By controlling the screwing depth of the jacking screw 35, the deformation degree of the spring 36 can be controlled, that is, the force movement distance of the structural member 1 can be controlled, so as to be applicable to occasions with different requirements. Of course, when it is applicable to occasions where the structural member 1 is not required to achieve buffering, the spring 36 can be removed, and the two connecting blocks 2 can be pushed to fit together by screwing in the jacking screw 35. The connection mechanism 3 further includes a plurality of connection components 37, and the plurality of connection components 37 are circumferentially distributed in the accommodating cavity with the structural member 1 as the center; The connecting assembly 37 includes a connecting strip 371 and two strip grooves 372.

In addition, through the elastic action of the spring 36, the structural member 1 can also achieve buffering when subjected to force. Secondly, by adjusting the degree of deformation of the spring 36, the distance the structural member 1 moves under force can also be controlled, which is convenient for application in occasions with different requirements. Moreover, when a layer plate is set between the two connecting blocks 2, the total length of the two structural members 1 after connection can be controlled by controlling the number of layers.
