[0055] Two symmetrically arranged first chambers 8 are opened inside the bracket 4, the left side of the slide 9 is slidably connected to the left wall of the first chamber 8, the first spring 10 is fixedly installed on the inner side of the slide 9, and the other end of the first spring 10 is fixedly connected to the inner wall of the first chamber 8, the card rod 11 is fixedly installed on the outer side of the slide 9, and the card rod 11 slides through to the outside of the bracket 4, and two symmetrically arranged card grooves 12 are respectively opened on the front and rear inner wall surfaces of the housing 1, and the card groove 12 coincides with the card rod 11, and the outer end surface of the card groove 12 is set as a left-facing inclined surface;

[0056] The fixing frame 13 is fixedly mounted on the left inner wall of the housing 1, and the inner bottom surface of the fixing frame 13 is coplanar with the top surface of the guide rod 7. The second spring 14 is evenly mounted on the left inner wall of the fixing frame 13. The left side of the abutment plate 15 is fixedly connected to the right end of the second spring 14, and the second spring 14 is slidably connected to the interior of the fixing frame 13. Two symmetrically arranged slide grooves 16 are respectively opened on the left and right inner walls of the housing 1, and the slide grooves 16 are slidably connected to the abutment plate 15. The inner height of the fixing frame 13 coincides with the height of the bracket 4.

[0057] The second chamber 17 is opened inside the mounting plate 3, the movable plate 18 is slidably connected to the wall of the second chamber 17, the push block 19 is highly mounted on the right side of the movable plate 18, and the push block 19 slides through to the right side of the mounting plate 3, the two symmetrically arranged push rods 20 are fixedly mounted on the left side of the movable plate 18, and the push rods 20 slide through to be set in the first chamber 8, and the left end face of the push rod 20 and the right end face of the slide plate 9 are arranged as matching inclined surfaces, and the left end face of the push rod 20 abuts against the right end face of the slide plate 9, the third spring 21 is evenly mounted on the left wall of the second chamber 17, and the right end of the third spring 21 is fixedly connected to the left side of the movable plate 18.

[0058] Working principle: When in use, place the filter 6 into the installation slot 5, then move the bracket 4 to the left through the through slot 2 into the housing 1, and use the guide rod 7 to ensure that the bracket 4 moves horizontally and stably to the left;

[0059] During this process, when the card rod 11 contacts the housing 1, it pushes the card rod 11 inward, causing the slide plate 9 to move inward synchronously and compress the first spring 10.
