A threaded rod 8 and a connecting rod 7 are inserted into both the positioning column 4 and the support block 3. A driving ball 6 is arranged at the inner end of the connecting rod 7. At the same time, a knob block 9 is arranged at the outer end of the threaded rod 8.

[0024] Please refer to Figure 2 and Figure 3 In this embodiment, clamping grooves 21 are respectively formed on both sides of the filter plate 2, and there are two clamping grooves 21 on each side. Arc-shaped grooves 201 are formed on both the upper and lower walls inside the clamping grooves 21.

[0025] Furthermore, the positioning column 4 is inserted and fixedly connected into the clamping groove 21, and the outer end face of the positioning column 4 is flush with the side surface of the filter plate 2.

[0026] Furthermore, the outer end of the positioning column 4 is fixedly connected to the upper and lower sides of the side surface of the support block 3, and the side surface of the support block 3 is closely attached to the side surface of the filter plate 2.

[0027] After the clamping groove 21 is provided on the side surface of the filter plate 2, the positioning column 4 is inserted into the clamping groove 21, and the positioning column 4 and the support block 3 are fixedly connected into one body, so that the filter plate 2 is supported by the support block 3.

[0028] Please refer to Figure 3 and Figure 4 and Figure 5 Through the through-hole part 31 is formed inside the support block 3, and a thread part 301 is arranged on the inner wall at one end of the through-hole part 31.

[0029] Furthermore, a part-receiving portion 41 is formed inside the positioning post 4. The part-receiving portion 41 communicates with the through-hole portion 31 and has the same diameter.

[0030] After the support block 3 is connected to the positioning post 4, the through-hole portion 31 and the part-receiving portion 41 formed inside them respectively are of the same size, and parts can be inserted into the through-hole portion 31 and the part-receiving portion 41 together for operation.

[0031] Furthermore, a threaded rod 8 is inserted into the through-hole portion 31, and the threaded rod 8 engages with the threaded portion 301. One end of the connecting rod 7 is fixedly connected to the inner end of the threaded rod 8, and the other end of the connecting rod 7 is fixedly connected to the driving ball 6.

[0033] A clamping ball 5 is provided inside the part-receiving portion 41. By rotating and pushing the threaded rod 8 provided inside the through-hole portion 31, when the connecting rod 7 and the driving ball 6 are rotating, they also move towards the inner end of the part-receiving portion 41. In this way, after the driving ball 6 pushes the clamping ball 5 out of the side wall of the positioning post 4, the pushed-out part of the clamping ball 5 will be fixed inside the filter plate 2.

[0034] Working principle:

[0035] The positioning posts 4 are inserted into the clamping grooves 21 on both sides of the filter plate 2, and the outer ends of the positioning posts 4 are connected to the support blocks 3, so that the support blocks 3 indirectly support the filter plate 2. A through-hole portion 31 and a part-receiving portion 41 are respectively formed inside the support block 3 and the positioning post 4. After the threaded rod 8 is inserted into the through-hole portion 31 and engages with the internal threaded portion 301, the threaded rod 8 can be pushed in or withdrawn inside the support block 3 by rotating the external knob block 9. A connecting rod 7 is provided at the inner end of the threaded rod 8, and a driving ball 6 is provided at the other end of the connecting rod 7. In this way, when the connecting rod 7 and the driving ball 6 are rotating, they can also be pushed in or withdrawn inside the through-hole portion 31 and the part-receiving portion 41. A clamping ball 5 is provided inside the part-receiving portion 41. When the driving ball 6 is pushed in, a part of the side surface of the clamping ball 5 will be pushed out of the side wall of the positioning post 4, and this pushed-out part will be stuck in the arc-shaped groove 201 inside the clamping groove 21 for fixation, so that the positioning post 4, the support block 3 and the filter plate 2 are fixed. When disassembly is required, rotate the knob block 9 in the reverse direction to separate the driving ball 6 from the clamping ball 5, so that the pushed-out part of the clamping ball 5 disengages from the arc-shaped groove 201, and after moving the support block 3 and the positioning post 4, the filter plate 2 can be removed.
