DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

The following embodiments are merely exemplary embodiments of the present invention, which should not be construed as limiting the scope of the invention, and therefore all equivalent variations of the claims are intended to be covered by the present invention.

The embodiment of the utility model provides an embodiment describes a buckle connecting device, it includes plug 2 and cassette 3; the plug 2 comprises a connecting column and a circular inserting disc 2-3 fixed at the end part of the connecting column; the clamping seat 3 is hollow, the side wall of the clamping seat is provided with an inverted T-shaped inlet, and the inverted T-shaped inlet comprises a plug-in tray inlet 3-1-1 for leading a plug-in tray 2-3 to pass in and out and a connecting column inlet 3-1-2 for leading a connecting column to pass in and out; the top of the clamping seat 3 is provided with a connecting column moving port 3-1-3 communicated with the connecting column inlet 3-1-2; the clamping seat 3 is provided with a limiting spring structure 5 in the inner cavity, and the limiting spring structure 5 comprises a sleeve 5-2 fixed at the bottom of the inner cavity of the clamping seat 3, a movable head 5-1 clamped in the sleeve 5-2, and a spring 5-3 with one end abutting against the bottom of the inner cavity of the clamping seat and one end abutting against the movable head 5-1 in the sleeve 5-2; when the spring 5-3 is unfolded, the movable head 5-1 shields the plug-in tray inlet 3-1-1; when the spring 5-3 is compressed, the movable head 5-1 is integrally arranged in the sleeve 5-2, and the top of the sleeve 5-2 is flush with the lower surface of the inserting disc inlet 3-1-1.

In the embodiment of the utility model, the other end of spliced pole sets up connecting rope draw-in groove one 2-1, the bottom of cassette sets up connecting rope draw-in groove two 3-2.

In the embodiment of the utility model, the connecting column is cylindrical, and the axis of the connecting column coincides with the axis of the inserting disc 2-3.

In the embodiment of the utility model, the end part of the movable head 5-1 is hemispherical.
