[0023] A slave bevel gear 302 is fixedly provided at one end of the screw rod 301, a main bevel gear 303 is movably provided at one side of the slave bevel gear 302, the main bevel gear 303 and the slave bevel gear 302 are connected in a meshing connection, a rotating rod 304 is fixedly provided at one side of the main bevel gear 303, a knob 305 is fixedly provided at one end of the rotating rod 304, a guide block 4 is fixedly provided at the other side of the lifting seat 101, and a cover plate 5 is movably provided at the top of the protective shell 1.

[0024] Specifically, a threaded plug tube 202 is fixedly provided at one end of the cover body 201, and the connection relationship between the threaded plug tube 202 and the paper tube body 2 is a threaded connection. The inner wall of the paper tube body 2 is provided with an internal thread, and the outer wall of the threaded plug tube 202 is provided with an external thread.

[0025] In this embodiment, a threaded plug tube 202 and a cover body 201 are provided, and the threaded plug tube 202 is rotated and displaced inside the paper tube body 2 by twisting the cover body 201. When the threaded plug tube 202 is completely screwed into the inside of the paper tube body 2, the installation of the cover body 201 is completed.

[0026] Specifically, a guide rod 401 is movably provided on the inner wall of the guide block 4 , and the connection relationship between the guide rod 401 and the guide block 4 is a sliding connection.

[0027] In this embodiment, the guide rod 401 and the guide block 4 are provided to guide the lifting platform 101 so that the lifting platform 101 can move vertically stably.

[0028] Specifically, the cover plate 5 and the protective shell 1 are movably connected via butterfly bolts 501 , and threaded holes matching the butterfly bolts 501 are provided on both sides of the top of the protective shell 1 .

[0029] In this embodiment, a butterfly bolt 501 is provided and the butterfly bolt 501 is rotated and displaced by screwing it. When one end of the butterfly bolt 501 is completely screwed into the threaded hole on the protective shell 1, the cover plate 5 can be restricted, thereby achieving the installation of the cover plate 5.

[0030] Specifically, a placement groove 6 is provided inside the paper tube body 2, and a reinforcing rod 601 is provided inside the placement groove 6. The reinforcing rod 601 is made of kraft paper.

[0031] In this embodiment, by setting a reinforcing rod 601, the overall anti-bending ability is greatly enhanced, and it is not easy to bend after being squeezed and collided by the outside. The reinforcing rod 601 directly enhances the pressure resistance of the paper tube body 2, and the protective shell 1 provides external protection for the paper tube body 2. The combination of the two can achieve high-strength pressure resistance.

[0032] Specifically, limit blocks 7 are fixedly provided on both sides of the inner wall of the protective shell 1 .

[0033] In this embodiment, by providing the limit block 7, it is possible to prevent the nut seat 3 from contacting the main bevel gear 303.

[0034] When in use, one end of the paper tube body 2 is placed in the groove on the lifting seat 101, and then the main bevel gear 303, the slave bevel gear 302 and the screw rod 301 are driven to rotate by turning the knob 305. The rotating screw rod 301 drives the paper tube body 2 on the lifting seat 101 to move vertically through the nut seat 3. When the lifting seat 101 moves downward, the paper tube body 2 can be brought into the interior of the protective shell 1.

[0035] Then, the cover plate 5 is covered, and then the butterfly bolt 501 is rotated and displaced by screwing the butterfly bolt 501. When one end of the butterfly bolt 501 is completely screwed into the threaded hole on the protective shell 1, the cover plate 5 can be restricted, and then the cover plate 5 is installed, so that the paper tube body 2 is in a closed space;

[0036] When taking out the paper tube body 2, the butterfly bolt 501 is rotated and displaced by twisting the butterfly bolt 501. When one end of the butterfly bolt 501 is removed from the threaded hole on the protective shell 1, the restriction on the cover plate 5 can be released, and then the cover plate 5 can be removed;

[0037] Then, by turning the knob 305, the main bevel gear 303, the slave bevel gear 302 and the screw rod 301 are driven to rotate. The rotating screw rod 301 drives the paper tube body 2 on the lifting seat 101 to move vertically through the nut seat 3. When the lifting seat 101 moves upward, the paper tube body 2 can be moved out.

[0038] To sum up, the high-strength pressure-resistant paper tube, by providing a protective shell 1 and a cover plate 5, places the paper tube body 2 inside the protective shell 1, and then covers the cover plate 5, so that the paper tube body 2 is in a closed space, effectively isolating external pollutants, greatly reducing the risk of pollutants invading the paper tube body 2, and the protective shell 1 can also resist external physical impact, extrusion and collision. This protection significantly reduces the risk of deformation or damage of the paper tube body 2 due to external forces. By providing a nut seat 3, a screw rod 301, a slave bevel gear 302, a main bevel gear 303 and a knob 305, the main bevel gear 303, the slave bevel gear 302 and the screw rod 301 are driven to rotate by turning the knob 305, and the rotating screw rod 301 drives the paper tube body 2 on the lifting seat 101 to move vertically through the nut seat 3, thereby facilitating the removal of the paper tube body 2 in the protective shell 1.
