The tooth grooves (265) are matched with the arc-shaped internal tooth (251). The limiting half ring A (26) is fixedly connected with the support block (25). The bottom of the limiting plate (22) is provided with two groups of limiting sliding blocks (24). The limiting sliding blocks (24) are provided with limiting sliding grooves (23). The guide rails (11) are arranged in the limiting sliding grooves (23), so that the limiting sliding blocks (24) are slidingly arranged on the guide rails (11). The limiting sliding blocks (24) are provided with limiting bolts (21) which are screw-connected. The limiting bolts (21) penetrate the limiting sliding blocks (24) and are in contact with the guide rails (11).

7. The fully automatic filter welding tool according to claim 6, characterized in that: The limiting half ring A (26) is provided with a limiting fixing plate (28). The limiting fixing plate (28) is provided with a limiting support frame (282). The limiting support frame (282) is hingedly provided with a limiting connecting plate (281). The limiting half ring B (27) is provided with a limiting extension rod (29). The limiting extension rod (29) is hingedly connected between the limiting connecting plate (281). The bottom of the limiting support frame (282) is provided with a limiting air cylinder (284). The limiting air cylinder (284) is provided with a limiting movable frame (283). The limiting movable frame (283) is hingedly connected with the limiting extension rod (29).

8. The fully automatic filter welding tool according to claim 7, characterized in that: The limiting half ring A (26) is provided with a pushing groove (264).
