Since the locking bone 214 is clamped up and locked in the locking groove 14 on the boss portion 12, it is ensured that the first fixing member 1 cannot rotate in the counterclockwise direction; at the same time, the other end of the insertion slot 13 is closed. When the fixing clip 211 is rotated clockwise to a certain position, it can no longer advance, so that the first fixing member 1 and the second fixing member 2 are completely locked in any rotation direction. At the same time, since the fixing clip 211 is completely caught in the insertion slot 13, the first fixing member 1 and the second fixing member 2 are fixed in the vertical direction.

6. When the first fixing member 1 is locked to the second fixing member 2, and the user rotates the object fixed to the first fixing member in a clockwise or counterclockwise direction, one side of the bottom convex bone 218 of the locking portion 213 The slope surface 219 needs to pass over the groove 233 above the casing 231. At this time, the wave spring is triggered to be compressed to allow the upper and lower spaces to realize the above-mentioned over-moving action, thereby completing the rotation function of the first fixing member 1. When the overrunning action is completed, the wave spring rebound reset can again position the convex bone 218 at the bottom of the buckle portion 213 in the groove 233 above the housing 231.

7. If the unlocking is required, the fixed object is removed from the second fixing member 2, and the quick release button 217 of the locking portion 213 of the second fixing member 2 needs to be pressed downward to make the locking bone position 214 downward. The straight edge of the lock groove 14 is avoided, and the object to which the first fixing member 1 is attached is rotated counterclockwise, and then the first fixing member 1 is vertically pulled out until the two objects are completely separated.

This example describes the specific operating principle of fixing in a clockwise direction. Of course, the present principle is also applicable to counterclockwise operation, and it is only necessary to set the components on the first fixing member and the second fixing member to operate in a counterclockwise direction.

The embodiments described above are preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. The scope of the present invention is not limited to the specific embodiments. Within the scope of protection of the present invention.
