Brief description of the drawings
Fig. 1 is the structural representation of one embodiment of ball pin of the present utility model.
In figure：100 spheroids；200 pin rods；Positioning center hole 1；Round platform 2；Tapered rod 3；Ladder platform 4：First halfpace 41,
Two halfpaces 42, the 3rd halfpace 43；Straight-bar 5：Plum blossom hole 51；Groove 6.
Embodiment
To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
On the one hand, as shown in figure 1, the utility model embodiment provides a kind of ball pin, including spheroid 100 and pin rod 200,
Spheroid 100 and pin rod 200 are structure as a whole, wherein：Ball end face of the spheroid 100 away from pin rod 200 is provided with positioning center hole 1, pin
Bar 200 includes round platform 2, tapered rod 3, ladder platform 4 and the straight-bar 5 being sequentially connected, and pin rod 200 is solid by round platform 2 and spheroid 100
Fixed connection, its right end face connection round platform 2 of tapered rod 3, left end face connection ladder platform 4, left end face diameter are more than right-hand end
Face diameter, and the cone angle of tapered rod 3 be 11 degree, ladder platform 4 including be sequentially connected the first halfpace 41, the second halfpace 42 and
