It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0019] An adjustable filter bag support frame, such as Figure 1-Figure 3 As shown, it includes a first rotating plate 1, a first guide frame 2, a sliding frame 3, a sleeve 4, an adjusting rod 5, a screw 6, a connecting rod 7, a telescopic rod 71, a second rotating plate 8 and a second guide frame 9. The middle of the first guide frame 2 is rotatably connected to the connecting rod 7, the lower part of the connecting rod 7 is slidably connected to the telescopic rod 71, the lower part of the telescopic rod 71 is rotatably connected to the second guide frame 9, the upper side of the connecting rod 7 is connected to the first rotating plate 1, the lower side of the telescopic rod 71 is connected to the second rotating plate 8, the first guide frame 2 is slidably connected to five sliding frames 3, and the second guide frame 9 There are five sliding frames 3 slidably connected to the upper part, the upper sliding frames 3 are in contact with the first rotating plate 1, and the lower sliding frames 3 are in contact with the second rotating plate 8. Three sleeves 4 are connected to the lower side of the upper sliding frames 3, and the lower part of the sleeves 4 is slidably connected to the adjusting rod 5. Seven adjusting holes are provided on the sleeves 4 for adjusting the length of the adjusting rod 5. The lower side of the adjusting rod 5 is connected to the adjacent lower sliding frame 3. Screws 6 are clamped on the sleeves 4, and the screws 6 are threadedly connected to the adjacent adjusting rods 5. A knob is provided on the screw 6 for easy rotation.

[0020] like Figure 1 and Figure 4 As shown, it also includes a gear 10, a support frame 11, a support rod 12, a limiting block 13 and a telescopic spring 14. The gear 10 is connected to the outer side of the first rotating plate 1, and the upper side of the sliding frame 3 at the upper right end is connected to the support frame 11. The support frame 11 is slidably connected to the support rod 12, and a telescopic spring 14 is connected between the support rod 12 and the support frame 11. The left part of the support frame 11 is slidably connected to the limiting block 13, the limiting block 13 is in contact with the gear 10, and the limiting block 13 is squeezed with the support rod 12. The limiting block 13 is a conical structure, which is convenient for limiting the position of the gear 10.

[0021] When using the utility model, first rotate the screw 6 to disengage the screw 6 from the adjusting rod 5, then slide the adjusting rod 5 to the length of the cloth bag, and then make the screw 6 engage with the adjusting rod 5 again to fix the sleeve 4 and the adjusting rod 5. After the adjusting rod 5 is fixed, the cloth bag is sleeved on the outside of the sleeve 4 and the adjusting rod 5, and then rotate the first rotating plate 1. Through the contact and cooperation between the first rotating plate 1 and the first guide frame 2, the upper sliding frame 3 slides open on the first guide frame 2. While the first rotating plate 1 rotates, the connecting rod 7 rotates, so that the telescopic rod 71 rotates, so that the second rotating plate 8 rotates, and through the contact and cooperation between the second rotating plate 8 and the second guide frame 9, the lower sliding frame 3 is opened. The sliding frame 3 slides open on the second guide frame 9. When the sliding frame 3 is opened, the sleeve 4 and the adjusting rod 5 are driven to open to support the cloth bag, thereby playing a role in being able to adjust the distance and relative position between the sliding frames 3 to adapt to the support requirements of cloth bags of different sizes. When the first rotating plate 1 rotates, the gear 10 is driven to rotate. Through the contact and cooperation between the gear 10 and the limiting block 13, the limiting block 13 slides to the right on the supporting frame 11, squeezing the support rod 12 to slide to the right, and the spring is squeezed and contracted. When the first rotating plate 1 completes the rotation, the spring rebounds, causing the limiting block 13 to reset, and the gear 10 is locked to prevent the first rotating plate 1 from rotating during use.
