[0023] The supporting mechanism also includes a plurality of arc plates 12, which are fixedly connected to the outer periphery of the circular plate 13 in a ring array manner. A plurality of support columns 11 are slidably connected to the fixed frame 17 in a ring array manner. The number of the support columns 11 is the same as the number of the arc plates 12. The support columns 11 abut against the corresponding arc plates 12. The end surface of the support column 11 located inside the fixed frame 17 is an inclined surface. The end of the support column 11 located outside the fixed frame 17 is hemispherical. A connecting plate 15 is fixedly connected to the side of the support column 11. A spring 14 is fixedly connected to the side of the connecting plate 15 close to the circular plate 13. The spring 14 is fixedly connected to the fixed frame 17.

[0024] A first fixed cylinder 2 is installed between the two slide plates 3 , the supporting mechanism is located at both sides of the interior of the first fixed cylinder 2 , and a wrapping film is wrapped around the first fixed cylinder 2 .

[0025] When the first fixed cylinder 2 needs to be installed, the first fixed cylinder 2 is placed between the two slides 3, and the first cylinder 4 is started. The output end of the first cylinder 4 drives the corresponding slides 3 to move away from or towards each other, so that the distance between the two slides 3 matches the size of the first fixed cylinder 2. Then, the operation of the first cylinder 4 is stopped, and the motor 10 is started. The output shaft of the motor 10 drives the circular plate 13 and multiple arc plates 12 to rotate. When the arc plate 12 rotates clockwise, the corresponding support column 11 is squeezed away from the circular plate 13, and the support column 11 gradually approaches the inner wall of the first fixed cylinder 2. The multiple support columns 11 cooperate to clamp the first fixed cylinder 2. When the arc plate 12 rotates counterclockwise, the support column 11 returns to its original position under the action of the rebound force of the connecting plate 15.

[0026] A second fixed cylinder 7 is installed inside the box body 1 and at a position on the back side of the first fixed cylinder 2. The interior of the second fixed cylinder 7 is hollow and both ends are open. The second fixed cylinder 7 is located above the first fixed cylinder 2.

[0027] When the second fixed cylinder 7 needs to be installed, the second fixed cylinder 7 is placed between the other two supporting mechanisms, and the second cylinder 6 is started. The output end of the second cylinder 6 drives the corresponding supporting mechanism to approach or move away from the second fixed cylinder 7, so that the distance between the other two supporting mechanisms matches the size of the second fixed cylinder 7. Then the operation of the supporting mechanism is started, and the second fixed cylinder 7 is fixed in the same way.

[0028] A receiving tube 16 is fixedly connected to the middle of the box body 1 .

[0029] Working principle:

[0030] When the first fixed cylinder 2 needs to be installed, the first fixed cylinder 2 is placed between the two slide plates 3, and the first cylinder 4 is started. The output end of the first cylinder 4 drives the corresponding slide plates 3 to move away from or towards each other, so that the distance between the two slide plates 3 matches the size of the first fixed cylinder 2. Then, the operation of the first cylinder 4 is stopped, and the motor 10 is started. The output shaft of the motor 10 drives the circular plate 13 and the plurality of arc-shaped plates 12 to rotate. When the arc-shaped plate 12 rotates clockwise, the corresponding support column 11 is squeezed away from the circular plate 13, and the support column 11 gradually approaches the inner wall of the first fixed cylinder 2, so that the plurality of support columns 11 cooperate to clamp the first fixed cylinder 2.

[0031] When the second fixing cylinder 7 needs to be installed, the second fixing cylinder 7 is placed between the other two supporting mechanisms, and the second cylinder 6 is started. The output end of the second cylinder 6 drives the corresponding supporting mechanism to approach or move away from the second fixing cylinder 7, so that the distance between the other two supporting mechanisms matches the size of the second fixing cylinder 7. Then the operation of the supporting mechanism is started, and the second fixing cylinder 7 is fixed in the same way.
