[0036] A sliding sleeve 7 is slidably arranged at one end of the outer cylinder 1 close to the sealing cover 3, and a plurality of limit rods 8 are arranged on the outer surface of the sliding sleeve 7;

[0037] A plurality of storage grooves 9 are formed on the outer surfaces of the plurality of limit rods 8, and a plurality of connecting rods 903 are arranged at one end of the plurality of storage grooves 9 away from the sliding sleeve 7;

[0039] In this embodiment, during use, the user moves the sliding sleeve 7 towards the sealing cover 3. The sealing cover 3 is threadedly connected to one end of the outer cylinder 1. When the limiting rod 8 enters the anti-slip groove 6, the grip rod 901 is pulled out from the storage groove 9. The grip rod 901 and the connecting rod 903 rotate 90° around a dot. Subsequently, the user holds the grip rod 901 and drives the sliding sleeve 7 to rotate on the surface of the outer cylinder 1. When the sliding sleeve 7 rotates, it drives the limiting rod 8 to rotate. When the limiting rod 8 rotates, it drives the anti-slip groove 6 and the anti-slip block 5 to rotate. When the anti-slip block 5 rotates, it drives the sealing cover 3 fixed thereto to rotate at one end of the outer cylinder 1, facilitating the separation of the sealing cover 3 from the outer cylinder 1. When the sliding sleeve 7 rotates back, it drives the sealing cover 3 to be tightened at one end of the outer cylinder 1, saving the time to find external tools and being beneficial to improving the work efficiency of disassembly and assembly. The rectangular block 902 fixedly embedded in one end of the grip rod 901 is made of iron. After the rectangular block 902 contacts the rectangular magnet 10, it is adsorbed, facilitating enhancing the stability of the rectangular block 902 and the grip rod 901 in the storage groove 9.

[0040] Embodiment 2 is as Figure 1 - Figure 4 shown. Rectangular magnets 10 are provided at one ends of multiple storage grooves 9 away from the connecting rod 903. The multiple rectangular magnets 10 are respectively used in cooperation with the multiple rectangular blocks 902. One ends of the multiple limiting rods 8 away from the sliding sleeve 7 are respectively used in cooperation with the inner walls of the multiple anti-slip grooves 6. A water inlet pipe 2 is provided at one end of the outer cylinder 1 away from the sealing cover 3. A sewage pipe 301 is provided at one end of the sealing cover 3 away from the outer cylinder 1. A water outlet pipe 4 is provided at one end of the outer cylinder 1 near the water inlet pipe 2. A housing 101 is provided inside the outer cylinder 1. A plurality of water outlet holes 102 are formed on the outer surface of the housing 101. Ultrafiltration membrane filaments 103 are provided on the inner wall of the housing 101. Anti-falling nets 104 are provided at both ends of the housing 101. Limiting rings 105 are provided at both ends of the outer cylinder 1. Sealing rings 106 are provided on the opposite sides of the two limiting rings 105. The outer ring of one of the limiting rings 105 is arranged on the inner wall of the outer cylinder 1 near the water inlet pipe 2, and the outer ring of the other limiting ring 105 is arranged on the inner wall of the sealing cover 3 near the outer cylinder 1.

[0041] In this embodiment, during use, the water inlet pipe 2 fixed to one end of the outer cylinder 1 is connected to an external water supply pipe. The sewage discharge pipe 301 fixed to one end of the sealing cover 3 discharges the filtered impurity liquid outwards. The water outlet pipe 4 fixed to one end of the outer cylinder 1 is connected to an external drinking water pipe, facilitating the supply of ultrafiltered water outwards. The ultrafiltration membrane filaments 103 inside the housing 101 perform the filtration and purification work on the water liquid. The water liquid filtered and purified by the ultrafiltration membrane filaments 103 leaves the inside of the housing 101 through the water outlet holes 102. The gaps of the anti-drop nets 104 at both ends of the housing 101 are smaller than the cross-sectional diameter of the ultrafiltration membrane filaments 103, facilitating the prevention of the ultrafiltration membrane filaments 103 from being washed out of the housing 101 by water and improving the stability of the ultrafiltration membrane filaments 103 located inside the housing 101. Both ends of the housing 101 are respectively in contact with two sealing rings 106. When the sealing cover 3 is tightened at one end of the outer cylinder 1, the limit ring 105 and the sealing ring 106 fixed to the sealing cover 3 drive to squeeze one end of the housing 101, so that the other end of the housing 101 squeezes the limit ring 105 and the sealing ring 106 fixed to the inner wall of the outer cylinder 1, causing the two sealing rings 106 to be deformed by extrusion. This is beneficial to improving the sealing performance between the sealing rings 106 and both ends of the housing 101, preventing leakage at both ends of the housing 101, and is beneficial to improving the stability of the filtration and purification work.

[0042] Working principle: When in use, the user moves the sliding sleeve 7 towards the sealing cover 3. The sealing cover 3 is threadedly connected to one end of the outer cylinder 1. When the limiting rod 8 enters the anti-slip groove 6, the grip rod 901 is pulled out from the storage groove 9. The grip rod 901 rotates 90° around a circular point with the connecting rod 903. Then the user holds the grip rod 901 and drives the sliding sleeve 7 to rotate on the surface of the outer cylinder 1. When the sliding sleeve 7 rotates, it drives the limiting rod 8 to rotate. When the limiting rod 8 rotates, it drives the anti-slip groove 6 and the anti-sliding block 5 to rotate. When the anti-sliding block 5 rotates, it drives the sealing cover 3 fixed thereto to rotate at one end of the outer cylinder 1, facilitating the separation of the sealing cover 3 from the outer cylinder 1. When the sliding sleeve 7 rotates back, it drives the sealing cover 3 to be tightened at one end of the outer cylinder 1, saving the time to find external tools and being conducive to improving the working efficiency of disassembly and assembly work. The rectangular block 902 fixedly embedded inside one end of the grip rod 901 is made of iron. After the rectangular block 902 contacts the rectangular magnet 10, it is adsorbed, facilitating enhancing the stability of the rectangular block 902 and the grip rod 901 in the storage groove 9. When in use, the water inlet pipe 2 fixed at one end of the outer cylinder 1 is connected to an external water supply pipe, and the sewage pipe 301 fixed at one end of the sealing cover 3 discharges the filtered impurity liquid outwards. The water outlet pipe 4 fixed at one end of the outer cylinder 1 is connected to an external drinking water pipe, facilitating the supply of ultrafiltered water outwards. The ultrafiltration membrane filaments 103 inside the housing 101 perform the filtration and purification work on the water liquid. The water liquid filtered and purified by the ultrafiltration membrane filaments 103 leaves the inside of the housing 101 through the water outlet holes 102. The gaps of the anti-drop nets 104 at both ends of the housing 101 are smaller than the cross-sectional diameter of the ultrafiltration membrane filaments 103, facilitating preventing the ultrafiltration membrane filaments 103 from being washed out of the housing 101 by water and improving the stability of the ultrafiltration membrane filaments 103 inside the housing 101. Both ends of the housing 101 are respectively in contact with two sealing rings 106. When the sealing cover 3 is tightened at one end of the outer cylinder 1, it drives the limiting ring 105 and the sealing ring 106 fixed to the sealing cover 3 to squeeze one end of the housing 101, so that the other end of the housing 101 squeezes the limiting ring 105 and the sealing ring 106 fixed to the inner wall of the outer cylinder 1, causing the two sealing rings 106 to be squeezed and deformed, which is conducive to improving the sealing performance between the sealing rings 106 and both ends of the housing 101 and preventing leakage at both ends of the housing 101, and is conducive to improving the stability of the filtration and purification work.
