[0025] Through the above structure, the adjusting rod 4 is inserted into the sleeve 3, and the extension length of the adjusting rod 4 can be adjusted conveniently, and the usage is flexible.

[0026] Combined with Figure 3 The locking structure includes at least one limiting hole 5 arranged on the adjusting rod 4, and a locking bolt 6 is inserted at the top of the sleeve 3. The locking bolt 6 passes through the limiting hole 5 and is threadedly connected to the sleeve 3.

[0027] Through the above structure, the adjusting rod 4 is extended to a suitable position, and the sleeve 3 and the adjusting rod 4 are locked and fixed by the locking bolt 6, which is convenient for adjustment and suitable for filter bags of different lengths with high flexibility.

[0028] Combined with Figure 1 and attached Figure 2 The bottom end of the sleeve 3 and the top end of the adjusting rod 4 are both provided with a reinforcement ring 7.

[0029] Through the above structure, the sleeve 3 and the adjusting rod 4 can be reinforced respectively by using the reinforcement ring 7 to ensure the stability of the overall framework.

[0030] Embodiment 2

[0031] Combined with Figure 2 and attached Figure 4 The fixed seat 2 is provided with a dust-beating structure for cleaning the external filter bag, and the dust-beating structure includes a support ring 8 arranged on the sleeve 3, and the support ring 8 is provided with at least one and evenly distributed fixed blocks 9, and the fixed blocks 9 are hingedly provided with a connecting rod 10 with a certain angle, and the bottom end of the connecting rod 10 is provided with a patter 11, and the fixed seat 2 is provided with a fixed plate 12 for easy disassembly and assembly, and a movable column 13 is inserted on the fixed plate 12, and a circular push plate 14 is provided at the bottom end of the movable column 13.

[0032] Through the above structure, the movable column 13 drives the circular push plate 14 to move up and down continuously, so as to squeeze the connecting rod 10. Since the connecting rod 10 is hinged on the fixed block 9, as the circular push plate 14 moves up and down continuously, it drives the clapping plate 11 to continuously clap the external filter bag, which is convenient for cleaning without the aid of external equipment and is easy to use.
