The base 3 is hooked with a hook 25 at the bottom of the middle seat 2 through two hanging feet 24. One side of the middle seat 2 is provided with a square mounting port 5, and the inner cavity is provided with a central annular groove 6 communicated with the square mounting port 5. A second inclined plane 26 with smooth transition is arranged at the intersection of the square mounting opening 5 and the central annular groove 6. And the distance of the opening part 27 of the central annular groove 6 is slightly smaller than the outer diameter of the annular lock catch 4. The annular lock catch 4 is deformed by forced compression so as to fit into the central annular groove 6 from the square mounting opening 5 of the intermediate seat 2. The annular lock catch 4 is provided with a pulling part 7 extending out of the square mounting opening 5, one side of the pulling part 7 is attached to the side wall of the square mounting opening 5, the other side of the side wall of the square mounting opening 5 and a gap 8 is reserved between the side wall of the square mounting opening 5, the pulling part 7 is pulled, and the annular lock catch 4 can rotate towards the gap 8. And an elastic piece 9 for resetting the annular lock catch 4 after rotation is arranged in the gap 8. The lock is characterized in that 4 locking teeth 11 which are circumferentially arranged are distributed in a central hole 10 of the annular lock catch 4, a first inclined plane 12 is arranged on one side of each locking tooth 11, guide protrusions 14 corresponding to the locking teeth 11 are distributed in a circular mounting hole 13 in the upper end of the middle seat 2, guide grooves 15 corresponding to the guide protrusions 14 are formed in the side wall of the bottom of the button 1, and locking grooves 16 matched with the locking teeth 11 are formed in the upper ends of the corresponding guide grooves 15.
