This invention proposes a high-frequency ultrasonic cutting tool for processing non-metallic materials. A second housing is located at the other end of a first housing. An ultrasonic transducer assembly is housed within the cavity formed by the first and second housings. A cutting head is connected to the end of the ultrasonic transducer assembly away from the slip ring. An auxiliary positioning mechanism is detachably connected to the outer wall of the first housing. This mechanism assists in adjusting the cutting edge of the cutting head and also helps the positioning mechanism connect to the mounting port of an external cutting machine. At least one adjustment groove is provided on the side wall of the first housing away from the second housing. Each adjustment groove contains an auxiliary positioning mechanism. The ultrasonic transducer assembly and the cutting head work together to replace conventional point-punching cutting. Edge sealing can be performed based on the cooperation of the ultrasonic transducer assembly and the cutting head, improving cutting efficiency. The auxiliary positioning mechanism facilitates adjustment of the cutting head position, and a parallel edge prevents horizontal rotation of the ultrasonic transducer body. A pre-pressure component further assists in improving cutting efficiency.

This utility model discloses a fine filter for gas treatment, including a cylindrical body and a filter element. The filter element is slidably disposed within the cylindrical body. It also includes a rotating ring, a transverse fixing component, and a longitudinal fixing component. The rotating ring is fitted onto the outer side wall of the top of the filter element and is rotatably connected to it. The transverse fixing component is disposed at the bottom of the filter element for transverse fixing. The longitudinal fixing component is disposed on the rotating ring for longitudinal fixing of the filter element. The slider is dovetail-shaped and mates with a dovetail groove. A snap-fit ​​hole communicates with the groove. One end of the snap-fit ​​hole has a recess that mates with a snap-fit ​​ball. The dovetail groove has an abutment portion that mates with the snap-fit ​​ball. This fine filter for gas treatment solves the problem mentioned in the background art of using a screwdriver to loosen the screws fixing the filter element before removing it, which is too complicated.
