Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.
[0025] In the field of floor lamps, the multi-angle rotating connection device generally refers to the floor rod. In the existing floor lamp design, there are two ways to rotate the lamp head relative to the floor rod. The first is that the lamp head and the floor rod are pivotally hinged, but the lamp head can only rotate up and down in the vertical direction relative to the floor rod, and the rotation direction is limited, and it cannot rotate at multiple angles;
[0026] The second type is that the lamp head of the floor lamp is hinged to the floor rod with a ball joint. Specifically, a ball head is provided at the top of the floor rod, and a ball groove is provided at the bottom of the lamp head. After the ball head is inserted into the ball groove, the damping between the ball head and the ball groove is relied on to achieve the limiting of the ball joint after the rotation. Although the above-mentioned ball joint structure can be rotated at multiple angles, the above-mentioned ball joint structure cannot be disassembled, so it needs to be shipped as a whole during the product transportation process, which increases the packaging volume and increases the transportation cost, which is not conducive to the promotion of floor lamps.
[0027] In the present utility model, if Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the utility model provides a multi-angle rotating connection device, which includes: a first connecting rod assembly 10 and a second connecting rod assembly 20, wherein the bottom of the first connecting rod assembly 10 is provided with a ball groove 11, and the top of the second connecting rod assembly 20 is provided with a ball head 21, and the ball head 21 extends into the ball groove 11 and is articulated with the ball groove 11 by a ball joint;

[0029] In the present utility model, the above-mentioned scheme is adopted, firstly, to overcome the disadvantage that the traditional pivot hinge structure has a limited rotation angle and can only rotate up and down at a numerical angle; secondly, to overcome the disadvantage that the traditional ball joint structure cannot be disassembled once installed, and needs to be shipped as a whole during product transportation, which increases the volume of the packaging and increases the transportation cost. This makes the present product not only able to adjust the rotation angle at multiple angles, but also makes the ball joint structure of the present product easy to disassemble, thereby reducing the packaging volume of the present product, reducing the transportation cost, and facilitating the promotion of the present product.
