Referring to fig. 1, a curtain rod connector includes a first rotating shaft 1 and two insertion rods 2 rotatably sleeved on a side wall of the first rotating shaft 1 and located on the same horizontal plane. The user inserts the two inserting rods 2 into the two curtain rods to be connected respectively, and the two curtain rods are connected.
The coaxial fixing rod 3 is fixedly connected to one end, far away from the first rotating shaft 1, of the inserting rod 2, the coaxial fixing ring 4 is fixedly sleeved on the side wall, close to the end of the inserting rod 2, of the fixing rod 3, the coaxial moving ring 5 is further slidably sleeved on the side wall of the fixing rod 3, and the sliding direction of the moving ring 5 is the same as the length direction of the fixing rod 3. The outer side wall of the fixing ring 4 is hinged with three first connecting rods 6, the three first connecting rods 6 are distributed on the outer side wall of the fixing ring 4 at equal angular intervals, and the rotating axes of the first connecting rods 6 and the central axis of the fixing rod 3 are perpendicular to each other but do not intersect. The outer side wall of the moving ring 5 is hinged with three second connecting rods 7, the three second connecting rods 7 are distributed on the outer side wall of the moving ring 5 at equal angular intervals, the rotating axis of the second connecting rods 7 and the central axis of the fixing rod 3 are perpendicular to each other but not intersected, and the positions of the three second connecting rods 7 correspond to the positions of the three first connecting rods 6 one by one. One end of the first connecting rod 6, which is far away from the fixed ring 4, and one end, which is far away from the movable ring 5, of the corresponding second connecting rod 7 are hinged together through a second rotating shaft 8, and the second rotating shaft 8 is perpendicular to the fixed rod 3 but not intersected with the fixed rod. When the user moves the shift ring 5 towards the solid fixed ring 4 translation, the contained angle of head rod 6 and corresponding second connecting rod 7 will diminish, head rod 6 will move towards the direction of keeping away from dead lever 3 with the nodical of corresponding second connecting rod 7, so a plurality of diameters that enclose into a circle by the nodical of head rod 6 and second connecting rod 7 will grow, the user alright insert head rod 6 and second connecting rod 7 on the curtain pole that the internal diameter enlarges, thereby let inserted bar 2 insert tightly smoothly on the curtain pole that the internal diameter enlarges. When the user is towards keeping away from solid fixed ring 4's direction translation shift ring 5, the contained angle of head rod 6 and corresponding second connecting rod 7 will grow, head rod 6 will move towards the direction of dead lever 3 with the nodical of corresponding second connecting rod 7, so a plurality ofly will diminish by the diameter that the nodical encloses into the circle of head rod 6 and second connecting rod 7, the user alright insert head rod 6 and second connecting rod 7 on the curtain pole that the internal diameter diminishes, thereby let inserted bar 2 insert tightly smoothly on the curtain pole that the internal diameter diminishes.
The side wall of the fixed rod 3 is sleeved with a coaxial rotating sleeve 9, the rotating sleeve 9 is positioned on one side of the moving ring 5 far away from the fixed ring 4, and one end of the rotating sleeve 9 is rotatably embedded in the moving ring 5. The side wall of the fixed rod 3 is provided with a thread groove 10 which is in thread fit with the inner side wall of the rotary sleeve 9. Two force application pieces 11 which are convenient for fingers to apply force are fixedly connected to the rotating sleeve 9, and the two force application pieces 11 are symmetrically arranged on the rotating sleeve 9. The user rotates the rotating sleeve 9 through the force applying sheet 11, and under the action of the thread, the rotating sleeve 9 can drive the moving ring 5 to slide on the fixed rod 3, so that the included angle between the first connecting rod 6 and the corresponding second connecting rod 7 is changed.
