[0021] The anti-friction mechanism includes a guide roller 10 . A plurality of grooves 11 are formed on the inner wall of the positioning ring 9 . The plurality of grooves 11 are distributed in a ring array. The guide rollers 10 are rotatably installed inside the plurality of grooves 11 .

[0022] The guide roller 10 is provided to guide the outer surface of the stainless steel barrel, and the sliding friction between the outer surface of the stainless steel barrel and the positioning ring 9 is converted into rolling friction between the stainless steel barrel and the guide roller 10, thereby avoiding wear on the outer wall of the stainless steel barrel when the stainless steel barrel is moved.

[0023] Among them, the fixing mechanism is composed of a fixed block 12, a movable plate 14, an adjusting screw 16, an adjusting piece 17 and a clamping plate 19. One end of the fixed block 12 is fixedly connected to the inner side wall of the connecting plate 5, and the other end of the fixed block 12 is provided with a movable groove 13. The movable plate 14 is slidably installed inside the movable groove 13. The upper end of the movable plate 14 is fixedly connected to a connecting block 18, and the end of the connecting block 18 is fixedly connected to a clamping plate 19. An adjusting screw 16 is rotatably installed at the bottom of the inner cavity of the movable groove 13. The other end of the adjusting screw 16 passes through the movable plate 14 and is inserted into the inside of the connecting block 18. The adjusting screw 16 is connected to the movable plate 14 and the connecting block 18 through threaded cooperation. An adjusting piece 17 is rotatably installed on the outer side wall of the connecting plate 5, and the adjusting piece 17 is fixedly connected to the adjusting screw 16.
