The said magnetic ring 29 is placed in the receiving groove of magnetic ring 28, and its position is limited by the cover plate 27 at the top of the receiving groove of magnetic ring 28. The circular groove 23 can prevent the joint between the clamping head 1 and the buckle base 2 from being impacted by an external force and make the connection firm and stable.

[0032] The opposite walls of the front housing 11 and the rear housing 12 are set with matching positioning columns 17 and positioning holes, and the front housing 11 and the rear housing 12 are matched and connected with screws and nuts.

Step 2: An acting force is applied to the left fastener 13 and the right fastener 14 via the fastener unfolding device to make the upper ends of the left fastener 13 and the right fastener 14 swing toward each other. The distance between the two clamping blocks 131 is increased, and the buckle head 21 can be removed from the clamping head 1 to separate the clamping head 1 and the buckle base 2.

[0035] In Step 2, the rope 19 is pulled up to make the upper ends of the left fastener 13 and the right fastener 14 swing toward each other. The distance between the two clamping blocks 131 is increased. When the distance between the two clamping blocks 131 is greater than the diameter of the clamping body 212, the buckle head 21 can be pull out from the clamping head 1.
