Specific implementation mode
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, this ball-joint includes shell 1, oscillating bearing 2 and panel seat 3, oscillating bearing 2 is located in shell 1 and joint
Support construction is equipped between 1 inner wall of bearing 2 and shell, panel seat 3, which has to be coaxially disposed with oscillating bearing 2 and be tightly inserted into, to close
Interconnecting piece 31 in bearings 2, the bottom of interconnecting piece 31 are equipped with locating shim 4, the inner wall of oscillating bearing 2 offer annular groove and
