[0030] Example 1:

[0031] Please refer to the attached Figure 1The rectangular movable connecting buckle includes an outer shell 10, an inner core 20 and a connector 30. The outer shell 10 and the inner core 20 are adapted rectangular bodies. There is a rectangular hollow through-hole 11 in the outer shell 10, and the inner core 20 is sized to be inserted into the hollow through-hole 11 and slide. The inner core is equivalent to being accommodated in the outer shell 10 and movable. It cannot fall out of the outer shell 10 due to the limited position of the accessories. Moreover, since the outer shell 10 and the inner core 20 are adapted rectangular bodies, they have a self-positioning effect of docking after positioning. Only after the orientation of the rectangular bodies is aligned can the outer shell 10 and the inner core 20 be inserted into it.

[0032] A card slot 21 is provided at one end of the inner core 20, and a card end 31 suitable for being snapped into the card slot 21 is provided at one end of the corresponding connecting piece 30; an elastic limiting piece 21 is provided on the inner core 20, and a limiting slide groove 12 is provided in the hollow through hole 11 in the outer shell 10, and the inner core 20 is assembled into the outer shell 10 in a way that its elastic limiting piece 22 is snapped into the limiting slide groove 12.

[0033] The limiting chute 12 includes two sections, namely a closed limiting section 121 and an open limiting section 122. The two sections are connected and conducted by a guide sliding arc 123. The closed limiting section has a guide sliding arc 123 on one side and a cut-off line 124 on the other side; the open limiting section has a guide sliding arc 123 on one side and a cut-off line 124 on the other side. From the overall view of this section of the limiting chute, it can be seen that its role is to guide and limit the elastic limiting member, allowing the elastic limiting member to move back and forth between the two sections, while limiting its maximum displacement through the cut-off lines 124 in the two outermost sections, thereby preventing the elastic limiting member 22 and the inner core 20 from falling out of the outer shell 10.

[0034] The elastic limiting member 22 includes a spring 221 , a push pin 222 and a spring hole 223 . The push pin 222 compresses the spring 221 and fits into the spring hole 223 .

[0036] When the ejector pin 222 is stuck at the cut-off line of the closing limit section 121, the end of the inner core 20 with the slot 21 is completely retracted into the hollow through hole 11 of the outer shell 10. When the ejector pin 222 is pushed / pulled and stuck at the cut-off line 124 of the opening limit section 122, the slot 21 on the inner core 20 is completely extended out of the outer shell.

[0037] The closed limit section 121 allows the inner core 20 to be retracted into the outer shell 10 with the card slot, and is a section of the inner core 20 that hides the card slot. The open limit section 122 allows the inner core 20 to slide out, showing a section of its card slot 21. The card slot 21 is shown to allow the connector 30 to be inserted into it, or the connector 30 to be taken out from it.

[0038] Please refer to the attached Figure 2 and attached Figure 4 The connector includes an integrated two-hole type or an independent two-piece kit type.

[0039] In this embodiment, an integrated two-hole connector structure is shown, wherein the external portion of the integrated two-hole connector 30 is an adaptable rectangular body, on which two parallel fixing holes 32 for fixing rope chains are provided for connecting two different rope chains.

[0040] On the inner core 20 , one end is a slot 21 and the other end is a rope chain fixing end, and the rope chain fixing end is provided with two rope chain fixing holes 23 .
