By adopting the technical scheme, the supporting blocks are fixed on the reinforcing pipes along the axial direction of the reinforcing pipes, and when the paper pipes are bent by external force, the resistance of the outer pipes, the supporting blocks, the reinforcing pipes and the inner pipes needs to be overcome, so that the supporting blocks of the structure further improve the bending resistance of the paper pipes.

Alternatively, the support blocks may be tapered from both sides near the reinforcing tube and the outer tube to the middle in a section perpendicular to the axis of the reinforcing tube.

By adopting the technical scheme, when the outer pipe is deformed under stress, the supporting block is easily deformed by the wide structure at the two sides of the supporting block and the narrow structure in the middle, so that the external force can apply work to the supporting block and the outer pipe in a deformation mode, the work to the reinforcing pipe and the inner pipe is reduced, and the integrity of the reinforcing pipe and the inner pipe is kept.

Optionally, the two ends of the inner pipe are provided with support sleeves, and the outer walls of the support sleeves abut against and support the inner wall of the end part of the inner pipe.

Through adopting above-mentioned technical scheme, the both ends of paper pipe are impaired the most place usually, and the support sleeve makes the both ends inner wall of annual inner tube supported, makes the inner tube both ends difficult emergence deformation under support sleeve's support from this, reduces the impaired possibility of inner tube.

Optionally, the support sleeve has a diameter that becomes progressively larger from one end to the other.

Through adopting above-mentioned technical scheme, support sleeve one end is thin, and the thick structure of one end makes support sleeve can insert the inner tube with thin one end fast to along with progressively inserting and butt and support the inner wall of inner tube.

Optionally, the outer wall of the end with the large diameter of the support sleeve is provided with a baffle, and the side wall of the baffle abuts against the end of the outer pipe.

Through adopting above-mentioned technical scheme, when the inner tube inner wall was supported to the support sleeve, the baffle butt was at the tip of outer tube simultaneously for the baffle seals the empty space between outer tube and the reinforcement pipe, and the external world can not get into easily between outer tube and the reinforcement pipe from this, can not wet the damage easily, prolongs the life of paper pipe.

Optionally, a plurality of limiting blocks are arranged on one side of the baffle facing the supporting blocks, and each limiting block is inserted between two adjacent supporting blocks.

Through adopting above-mentioned technical scheme, the space between outer tube and the reinforced pipe is further shutoff to the stopper, unless all supporting shoes all break away from outer tube and reinforced pipe in addition, the stopper can make supporting sleeve and supporting shoe can not rotate relatively to make the space between outer tube and the reinforced pipe can not lack the support of supporting shoe.

In summary, the present application includes at least one of the following beneficial technical effects:

1. the supporting piece is fixedly connected between the reinforcing pipe and the outer pipe, so that a gap is formed between the reinforcing pipe and the outer pipe, when the outer pipe is deformed to a certain extent by external force, a space capable of accommodating the deformation of the outer pipe is formed between the outer pipe and the reinforcing pipe, and the pressure of the outer pipe on the reinforcing pipe is reduced, so that the reinforcing pipe and the inner pipe cannot bear excessive pressure easily, the possibility of integral bending of the paper pipe is reduced, and the bending resistance of the paper pipe is improved;
