When the end face of the cross keel 32 is abutted against the bottom wall of the corresponding fixing groove 7, the inclined teeth 81 are reset under the action of the self elastic force and form locking fit with the corresponding tooth grooves 82, so that the fixing of one end part of the cross keel 32 is realized.

Subsequently, the fixing grooves 7 of the other main keel 31 are aligned with the corresponding auxiliary keels 32. The main runner 31 is pushed to move and the other end of the cross runner 32 is inserted into the fixing groove 7. In the same way, when the other end face of the cross keel 32 is abutted against the bottom wall of the corresponding fixing groove 7, the helical teeth 81 are reset under the action of self elasticity and form locking cooperation with the corresponding tooth grooves 82, so that the fixing of the other end part of the cross keel 32 is realized. The keel component 3 can be assembled by reciprocating in this way;

At this time, the upper end portion of the control rod 161 is inserted into the control groove 17, and the mounting block 18 is made to abut against the control block 162. Subsequently, the mounting block 18 drives the rotating disc 121 to rotate the driving block 122 under the pushing of the control block 162, so that the locking rod 41 horizontally slides against the driving block 122. When the locking lever 41 is inserted into the locking groove 42, the stopper 22 is caught in the corresponding stopper groove 23. Then the buckle 1 is released, and when the upper end side wall of the locking rod 41 abuts against the upper end inner wall of the locking groove 42, the position limitation of the buckle 1 in the vertical downward direction is realized. At this time, the detent ball 15 is fitted into the detent groove 14, thereby achieving position limitation of the rotating disc 121 in the circumferential direction.

At this time, the driving block 122 is gradually disengaged from the locking lever 41, and the detent ball 15 is gradually disengaged from the detent groove 14, and at the same time, the relief groove 19 is gradually aligned with the locking lever 41. Subsequently, the mounting ring 20 drives the locking lever 41 to move reversely by the elastic force of the spring 21. When one end of the locking lever 41 is inserted into the receding groove 19, the other end is completely disengaged from the locking groove 42, thereby unlocking the buckle 1. Subsequently, the pinch plate 1 moves vertically downwards under the action of the gravity of the pinch plate 1, and when the control rod 161 is completely separated from the control groove 17 and the installation pipe 9 is completely separated from the installation groove 11, the pinch plate 1 can be detached. When the buckle 1 is installed, the locking rod 41 is pulled to move, and the locking rod 41 is separated from the abdicating groove 19. Then, the rotary dial 121 is rotated reversely, and the lock lever 41 is positioned between the driving block 122 and the escape groove 19.
