[0024] By adopting the above technical solution, rotating the turntable 2 drives the cam 52 to rotate.

[0025] The top ends of the two filter cartridge bodies 3 are provided with positioning grooves 31 , and the connecting rod 521 is rotatably inserted into the positioning grooves 31 . The top ends of the two filter cartridge bodies 3 are rotatably installed with two symmetrically distributed locking plates 51 , and the cams 52 are in contact with the corresponding locking plates 51 .

[0026] By adopting the above technical solution, the cam 52 drives the locking plate 51 to rotate and shrink.

[0027] Two symmetrically distributed positioning rods 32 are fixedly installed at the top of the two filter element bodies 3, and the positioning rods 32 are located in the rotating shaft of the corresponding locking plate 51. A return spring 53 is sleeved on the two positioning rods 32, and the upper and lower ends of the return spring 53 are fixedly connected to the top of the filter element body 3 and the upper surface of the locking plate 51 respectively.

[0028] By adopting the above technical solution, the cam 52 drives the locking plate 51 to rotate and contract, and tightens the reset spring 53.

[0037] Working principle: When the utility model is in use, first insert the filter element body 3 into the guide cylinder 12, then rotate the turntable 2 to drive the cam 52 to rotate, and the cam 52 drives the locking plate 51 to rotate and contract, and tighten the reset spring 53, then press the filter element body 3 to the bottom, and release the turntable 2. At this time, the locking plate 51 is reset by the rebound force of the reset spring 53, so that the locking plate 51 is inserted into the locking groove 121, and the filter element body 3 is locked and fixed. When the two filter element bodies 3 need to be taken out, only one of the turntables 2 needs to be rotated. The turntable 2 drives the driving gear 45 to rotate through the teeth 21, and the driving gear 45 drives the other turntable 2 to rotate synchronously through the bevel gear 46 and the drive shaft 44, thereby achieving the purpose of unlocking the two filter element bodies 3 at the same time by using the drive assembly 4.
