In the embodiment shown in FIG. 1, the ball receiving means is composed of two balls 20 and 30, and the ball 60 is rotated in a state where the two balls 20 and 30 are engaged. And a spherical groove that can be inserted into the groove is formed. The ball holders 20 and 30 are provided with connecting rods 23, 24, 25 and 26 and nuts 33 and 34, which are inserted into the through holes formed in the transverse direction, 35, and 36 to form a hexahedron as a whole, but grooves having bottom surfaces 29 and 39 are formed at the upper center so that the power supply circuit unit 40 can be installed in a coupled state have. An insertion portion 28 is provided on the upper surface of the ball catching tool 20 for inserting the side plate 13. An insertion portion 27 for inserting the side plate 12 is installed on the upper surface of the ball catching mouth 30 A bottom surface 29 is formed so as to be lowered from the upper surface of the ball catching tool 20 and a bottom surface 39 is formed so as to be lowered from the upper surface of the ball catching tool 30. [

The hemispherical grooves 21 and 22 which are inwardly hemispherical grooves are formed in the receiving surfaces 18 and 19 of the ball holders 20 and 30 so as to receive the ball 60, Respectively.

The ball 60 is installed at the upper end of the pipe 51 so that the electric wire 41 passes through the lower portion of the pipe 60. The pipe 51 is connected to the bushing 60 provided at the upper surface 53 of the housing 58 of the LED 50, 52 so that the ball 60 is coupled to the housing 58 of the LED 50 or the like. In addition, the ball 60 is formed with a cut portion that is incised downward with respect to the upper vertex of the center of the ball 60. It is preferable that the incision portion is formed so as to be gradually narrowed downward, and the incision portion can extend to the upper end portion of the pipe 51 when the incision portion is maximally extended. The ball 60 is divided into hemispherical pieces 61 and 62 by a cutting portion and the hemispherical pieces 61 and 62 are brought close to each other when a force is exerted from the outside so that the width of the cut portion is reduced, It is preferable to form a voluminous material and structure so as to be restored to its original position when removed. The radius of curvature of the hemispherical grooves 21 and 22 is larger than the radius of curvature of the hemispherical pieces 61 and 62 so that the hemispherical pieces 61 and 62 can be pressed when an external force is applied to the ball 60. [ It is preferable to form it smaller.
