[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4The filter body 5 is provided with a filter body 5 in the inner cavity of the filter body 5, and a terminal post 4 is provided on the outer wall of the filter body 5. The surface of the filter body 5 is provided with a plurality of limit grooves 6. The inner cavity of each limit groove 6 is provided with an elastic snap-fit assembly. The elastic snap-fit assembly includes a rotating shaft 7 rotatably connected to the inner wall of the limit groove 6. The lower surface of each rotating shaft 7 is fixedly connected to a push block 8. The upper surface of each rotating shaft 7 is fixedly connected to an L-shaped plate 9. The outer side of each L-shaped plate 9 is fixedly connected to the upper surface of the connecting seat 2 by a return spring 10. The modular assembly splicing design is adopted and matched with the elastic snap-fit assembly to achieve the purpose of quick disassembly, which is convenient for subsequent maintenance. When disassembling, the push block 8 is deflected outward, and the push block 8 drives the rotating shaft 7 to rotate in the limit groove 6. The rotating shaft 7 drives the L-shaped plate 9 to deflect and stretch the return spring 10, so that the shell 1 and the connecting seat 2 are separated to achieve the purpose of quick disassembly, which is convenient for subsequent maintenance.

[0024] like Figures 1-4 As shown, the end of the lower surface of the connecting seat 2 is slidably connected to the sliding seat 3, and the end of the push block 8 is flush with the height of the center of the lower surface of the connecting seat 2. The inner cavity of the sliding seat 3 is provided with a T-slot, and the inside of the T-slot is slidably connected to the rack 13. A limiting component is provided on the lower surface of the rack 13. The outer side of the sliding seat 3 is fixedly connected to the center of the T-slot. The middle part of the support frame 11 is threadedly connected to a bolt 12, and one end of the bolt 12 is fixedly connected to the end of the rack 13. Due to the self-locking function of the thread, the rack 13 can be effectively prevented from loosening, and the spur gear 18 can be prevented from loosening, thereby further improving the stability of the power connection.

[0025] like Figures 1-4 As shown, the limit assembly includes a two-way screw rod 14, and there are several two-way screw rods 14. The center of each two-way screw rod 14 is transmission-connected with a spur gear 18, and the spur gear 18 is meshed with the rack 13. Both ends of each two-way screw rod 14 are fixedly connected with a stopper 15, and the surface of each two-way screw rod 14 is symmetrically threaded with a hollow block 16, and the outside of each hollow block 16 is fixedly connected with a stop plate 17. The position of the main body is adjusted with a reasonable wire length to avoid the influence of the wire being too long on the operation of the equipment. When moving, the bolt 12 is rotated in the opposite direction, and the bolt 12 drives the rack 13 to move, and the rack 13 drives several spur gears 18 to rotate. The spur gear 18 drives the two-way screw rod 14 and the stopper 15 to move inward through the two-way screw rod 14. At this time, the main body is slid on the surface of the sliding seat 3. When sliding to the appropriate distance, the bolt 12 is rotated forward so that the hollow block 16 is against the lower end of the main body, thereby improving the stability of the power connection.

[0026] Working principle: When in use, first connect the terminal 4 to the power inlet. When adjusting the position of the filter, reverse-rotate the bolt 12 during movement. The bolt 12 drives the rack 13 to move, and the rack 13 drives several spur gears 18 to rotate. The spur gears 18 drive the double-threaded lead screw 14 and the double-threaded lead screw 14 and the stopper 15 to move inward. At this time, slide the main body on the surface of the sliding seat 3. When sliding to an appropriate distance, rotate the bolt 12 forward to make the hollow block 16 abut against the lower end of the main body, improving the stability of the electrical connection and effectively avoiding the influence of too long wires on the equipment. And due to the self-locking limit function of the thread, the rack 13 is prevented from shifting, resulting in the spur gear 18 shaking, improving the stability of the equipment. The modular assembly and splicing design and the cooperation with the elastic buckle assembly are used to achieve the purpose of quick disassembly, which is convenient for subsequent maintenance. When disassembling, deflect and push the push block 8 outward. The push block 8 drives the rotating shaft 7 to rotate in the limit groove 6. The rotating shaft 7 drives the L-shaped plate 9 to deflect and stretch the return spring 10 to separate the housing 1 from the connecting seat 2 to achieve the purpose of quick disassembly, which is convenient for subsequent repair and maintenance. The overall structure of the device is simple and the operation is convenient, which is suitable for large-scale promotion.

[0027] The above are only the preferred embodiments of the present invention, and do not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as the technical content of the technical solution of the present invention is not departed from, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
