If the locking sleeve 10 rotates counterclockwise at this time, the wedge 18 is driven to rotate counterclockwise, because the outer end of the wedge 18 is tightly pressed by the arc wedge surface 261 to form self-locking, the locking sleeve 10 cannot be unlocked without external force, the wedge 18 cannot rotate, and the first column 131 and the connection base 16 are in a locked state. In particular, the first block 181 is bent clockwise relative to the second block 182, and when the wedge 18 rotates counterclockwise, the pressing force between the wedge 18 and the circular wedge surface 261 is increased, and the friction force is increased accordingly, so as to further ensure that the lock sleeve 10 cannot be unlocked without external force, the wedge 18 cannot rotate, and the first column 131 and the connection base 16 are in a locked state. After the connecting base 16 and the first cylinder 131 are locked, the third locking nut 12 is screwed upwards, so that the locking stability of the hanger is improved.

When unlocking, the third locking nut 12 is slightly loosened, the pushing block 25 is abutted against the wedge block 18 by utilizing the unlocking sleeve 11, the counterclockwise rotation of the wedge block 18 is prevented, the locking sleeve 10 is rotated counterclockwise, the extrusion force between the wedge block 18 and the locking platform cannot be increased, when the locking friction force between the wedge block 18 and the arc wedge surface 261 is overcome, and the locking sleeve 10 rotates counterclockwise to be in contact with the wedge block 18 and the toggle tip 27, the unlocking sleeve 11 stops acting on the unlocking sleeve 11 and continues to rotate the locking sleeve 10 counterclockwise, the toggle tip 27 pushes the wedge block 18 to rotate counterclockwise until the inner end of the wedge block 18 rotates to be completely positioned in the mounting groove 163, and then unlocking can be realized. After the unlocking, the first cylinder 131 and the connecting base 16 are in a relaxed state, and the pipeline can be disassembled by pulling the first cylinder 131 downwards, so that the pipeline is convenient and quick.

In another embodiment of the present invention, a gap is formed between the lower bottom surface of the pushing block 25 and the upper bottom surface of the avoiding ring groove 111, so that after the unlocking sleeve 11 is installed in the connecting base 16, the lower bottom surface of the pushing block 25 is higher than the groove bottom surface of the installation groove 163, so as to prevent the pushing block 25 from falling into the avoiding groove 24 and further from being stuck during the rotation of the unlocking sleeve 11.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
