When the drainage hole 3 is blocked, the second electromagnet 14 is turned off and the first electromagnet 13 is started. The first electromagnet 13 will adsorb the piston block 12 located in the middle, and the piston cylinder 10 will transport the internal gas to the telescopic airbag 9 through the hose 11. The telescopic airbag 9 will extend under the action of the gas, thereby driving the slide rod 7 to slide away from the telescopic airbag 9, and the slide rod 7 will drive the pressing ring 8 to press the other elastic sheet 4, thereby pushing the insertion rod 5 on the side wall of the other elastic sheet 4 into the other drainage hole 3, thereby pushing out the impurities blocked in the drainage hole 3, and starting drainage through the first drainage hole 3, so that the drainage hole 3 of the support tube 2 remains unobstructed.

[0043] Furthermore, a first iron ring 19 is fixedly connected to the middle of the outer wall of the piston cylinder 10, and a second iron ring 20 and a third iron ring 21 are fixedly connected to the outer walls at both ends of the piston cylinder 10 respectively. The first iron ring 19, the second iron ring 20 and the third iron ring 21 can position the permanent magnet 16 and prevent the permanent magnet 16 from automatically shifting.

[0044] Working principle: In the present invention, when the drainage tube 1 is used, the support tube 2 is placed in the pancreas. When the support tube 2 is placed, the pressure ring 8 is located between the two elastic sheets 4, and the two insertion rods 5 will not extend out of the drainage hole 3, so that when the support tube 2 is placed, the support tube 2 will not be restricted by the insertion rods 5. After the support tube 2 and the drainage tube 1 are placed, the second electromagnet 14 adsorbs the piston block 12, so that the piston block 12 located in the middle position of the piston cylinder 10 slides toward the second electromagnet 14, and the piston cylinder 10 extracts the gas in the telescopic airbag 9 through the hose 11, and the telescopic airbag 9 will shrink, thereby driving the sliding rod 7 to slide in the direction of the telescopic airbag 9, and the sliding rod 7 will drive the pressure ring 8 to press one of the elastic sheets 4, and the elastic sheet 4 will tilt, and one of the insertion rods 5 in the support tube 2 will pass through the drainage hole 3, and the end of the insertion rod 5 will push up the local position in the pancreas, so that the drainage hole 3 at the adjacent position is not easy to be blocked. When the drainage hole 3 is blocked When the second electromagnet 14 is turned off and the first electromagnet 13 is turned on, the first electromagnet 13 will absorb the piston block 12 in the middle, and the piston cylinder 10 will transport the internal gas to the telescopic airbag 9 through the hose 11. The telescopic airbag 9 will extend under the action of the gas, thereby driving the slide bar 7 to slide away from the telescopic airbag 9. The slide bar 7 will drive the pressing ring 8 to press the other elastic sheet 4, thereby pushing the insertion rod 5 on the side wall of the other elastic sheet 4 into the other drainage hole 3. Thereby, impurities blocked in the drainage hole 3 are pushed out, and drainage begins through the first drainage hole 3, so that the drainage hole 3 of the support tube 2 remains unobstructed, and the adjustment is also extremely convenient and safe. When the elastic sheet 4 is pressed, the elastic airbag 27 on the side wall of the elastic sheet 4 will be squeezed, thereby pressing the internal air into the sliding cavity 24, and the extension rod 25 in the sliding cavity 24 will be pushed out by the air pressure, thereby extending the extension of the insertion rod 5, thereby improving the drainage space and drainage efficiency of the drainage hole 3.
