[0025] The clamping assembly includes a driven ring 7, a plurality of outer bevel blocks 8 and a plurality of elastic clamping members. The driven ring 7 is sleeved on the mounting ring 2, and the driven ring 7 is rotatably connected to the threaded ring 3. The plurality of outer bevel blocks 8 are fixedly mounted on the side wall of the driven ring 7. The plurality of elastic clamping members are respectively movably inserted into the plurality of through holes opened on the side wall of the mounting ring 2, and the plurality of elastic clamping members are respectively movably inserted into the plurality of sliding holes 12 opened on the side wall of the elbow 1. The plurality of outer bevel blocks 8 are correspondingly arranged with the plurality of elastic clamping members. The elastic clamping members include an inner bevel block 9, a side plate 10 and a first spring 11. The inner bevel block 9 is movably inserted into the through hole and the sliding hole 12 of the mounting ring 2. The inclined surface of the inner bevel block 9 is fitted with the inclined surface of the outer bevel block 8. A rubber pad is fixedly mounted on one end of the inner bevel block 9 facing the inner side of the elbow 1. The side plate 10 is fixedly mounted on the inner bevel block 9. Both ends of the first spring 11 are respectively fixedly connected Connected to the side plate 10 and the inner wall of the mounting ring 2, a guide block 17 is fixedly installed on the inner wall of the driven ring 7, and one end of the guide block 17 is movably arranged in a groove provided on the outer surface of the mounting ring 2. The pipe to be connected is inserted into one end of the elbow 1. Then, the threaded ring 3 is rotated, and the threaded ring 3 drives the driven ring 7 to move, so that the outer bevel block 8 moves toward the inner bevel block 9. Under the extrusion of the outer bevel block 8, one end of the inner bevel block 9 moves toward the inner side of the elbow 1, and the first spring 11 is stretched. Then, the clamping work of the connected pipe is completed by the inner bevel block 9.

Since the traction ring 4 is rotatably connected with the mounting ring 2, and the traction ring 4 is threadedly connected with the elbow 1, when the traction ring 4 is rotated, the inner oblique block 9 slides in the sliding hole 12. Under the effect of limiting the movement, the mounting ring 2 moves, thereby driving the connected pipe to move toward the sealing ring 6. Through the continuous rotation of the traction ring 4, the connected pipe is tightly combined with the sealing ring 6. Then, the hook of the movable column 14 and the hook of the shell 15 are respectively put on the hanging rings 13 of the two traction rings 4. At this time, the second spring 16 is in a stretched state, and the force in the opposite direction of the second spring 16 can be decomposed into a force in the direction of the elbow 1. Since the compressed sealing ring 6 applies a force to the traction ring 4 toward the end of the elbow 1, and the force applied by the second spring 16 is opposite to the force applied by the sealing ring 6, it is convenient to balance the force on the traction ring 4.
