[0022] The fixing assembly includes a slide groove 13, a slider 14, a through groove 16, a second spring 17, a fixed groove 18 and a fixed rod 19. There are multiple groups of fixed grooves 18, and the multiple groups of fixed grooves 18 are evenly opened on the inner side of the annular guide rail 7. The through groove 16 is opened at the top and bottom of the annular slider 15. The interiors of the two groups of annular sliders 15 are penetrated by a fixing rod 19, and the fixing rod 19 extends to the interior of the fixed groove 18 and cooperates with each other. A slide groove 13 is opened on one side of the fixing rod 19, and a slider 14 connected to the through groove 16 is slidably provided at the inner top of the slide groove 13, and a second spring 17 connected to the slider 14 is provided at the inner bottom of the slide groove 13.

[0023] The limiting clamping assembly includes a spring 18, a limiting rod 9, a receiving groove 10, an L-shaped connecting plate 11 and an arc-shaped push block 12. The L-shaped connecting plate 11 is located at the top and bottom of the outer side of the annular slider 15. The two groups of L-shaped connecting plates 11 are provided with an arc-shaped push block 12 on one side close to the extension sleeve 6, and the arc-shaped push block 12 cooperates with the arc-shaped resistance block 4. The two groups of L-shaped connecting plates 11 are provided with a receiving groove 10 that is interconnected with the inside of the through groove 16 on one side away from the arc-shaped push block 12. The two groups of receiving grooves 10 are both sleeved with a limiting rod 9 extending to the outside thereof, and the limiting rod 9 cooperates with the fixing rod 19. The two groups of limiting rods 9 are both sleeved with a spring 18 that is interconnected with the L-shaped connecting plate 11 on one side away from the L-shaped connecting plate 11.

[0024] One front end of one set of arc-shaped resisting blocks 4 and one back end of another set of arc-shaped resisting blocks 4 and one back end of one set of arc-shaped pushing blocks 12 and one front end of another set of arc-shaped pushing blocks 12 are all provided with a guiding inclined surface 1, and the two sets of guiding inclined surfaces 1 cooperate with each other.

[0027] Working principle: When in use, the operator can first take a set of stainless steel sleeves 1 and drive the extension sleeve 6 to insert into the side of another set of stainless steel sleeves 1 close to the sealing ring 3, and then after the insertion is completed, the sealing ring 3 can be snapped into the inside of the annular groove 5 to improve the sealing performance of the later assembly of multiple sets of stainless steel sleeves 1;

[0028] Then, the limiting rod 9 is pulled to move inside the receiving groove 10 to realize the stretching operation of the spring 1 8. At this time, the movement of the limiting rod 9 can release the resistance to the fixing rod 19, and then the elastic restoring force of the spring 2 17 can drive the fixing rod 19 to move up inside the through groove 16 to disengage from the fixing groove 18 to release the fixation of the annular slider 15. At the same time, the upper part of the fixing rod 19 can also drive the slide groove 13 to move up outside the slider 14. Finally, the annular slider 15 and the above components are driven to rotate inside the annular guide rail 7 by rotating the L-shaped connecting plate 11 and the arc-shaped push block 12.

[0029] Then, through the structural design of the guiding inclined surface 1 at one end of the arc-shaped push block 12 and the arc-shaped resisting block 4, the arc-shaped push block 12 can push the two groups of stainless steel sleeves 1 closer to each other when rotating on the outer side of the arc-shaped resisting block 4, so as to achieve a tight assembly.

[0030] Finally, the limit rod 9 is released, and the elastic restoring force of the spring 18 can drive the limit rod 9 to move inside the storage groove 10. By designing the guide slope 2 on the side where the limit rod 9 and the fixing rod 19 are close to each other, the limit rod 9 can push the fixing rod 19 to move inside the through groove 16 and be inserted into the fixing groove 18 during the movement, thereby fixing the position of the arc-shaped push block 12. At the same time, the fixing rod 19 can also drive the slide groove 13 to move outside the slider 14 to realize the compression operation of the spring 2 17.
