Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-10: the utility model provides a connect ball, includes casing 1, casing 2 and the main casing body down, the main casing body constitute by two basic casings 3, constitute the inside vacuole formation 4 of the main casing body after, last casing 1 be equipped with first adapting unit 5, casing 2 is equipped with second adapting unit 6 down, go up casing 1 and casing 2 and set up respectively in the upper and lower both sides of the main casing body down, pass cavity 4 and pass through screw 7 fixed connection by first adapting unit 5 and second adapting unit 6 to go up casing 1, casing 2 and two basic casings 3 combinations form a polyhedral spheroid down. Go up the upper end of casing 1 and the lower extreme of casing 2 down and be equipped with vertical blind hole 8 respectively, and the axis of vertical blind hole 8 coincides each other, the lower extreme of going up casing 1 and the upper end of casing 2 down are equipped with first breach 11, and one side of basic casing 3 all is equipped with second breach 12, and it forms slant blind hole 10 with the first breach 11 combination of last casing 1 and casing 2 down respectively, and the opposite side of basic casing 3 is equipped with third breach 13, forms horizontal blind hole 9 after the third breach 13 combination of two basic casings 3, and the axis of horizontal blind hole 9 is located same horizontal plane, and the connecting rod can insert vertical blind hole 8 respectively, horizontal blind hole 9 and slant blind hole 10 to carry out the work of putting up of model. All be equipped with arch 14 on the inner wall of vertical blind hole 8, this arch 14 can reduce the area of contact between connecting rod and the vertical blind hole 8 to make things convenient for the plug of connecting rod (horizontal blind hole 9 and slant blind hole 10 also can set up arch 14 at relevant position as required, this belongs to prior art, and the description is not done here).
