Pneumatic control test probe

The invention discloses a pneumatic control test probe, which comprises a needle tube; the first sealing seat is arranged at one end of the needle tube, and an air inlet is formed in the first sealing seat; the needle shaft is arranged in the needle tube, and one end of the needle shaft extends out of the other end of the needle tube; a limiting circular truncated cone is arranged on the outer wall of the needle shaft, and a first sealing ring is arranged at the other end of the needle shaft; the elastic piece is arranged on the needle shaft in a sleeving mode, and the elastic piece is arranged between the limiting step and the other end of the needle tube. The pneumatic control test probe solves the problem that an existing test probe cannot adapt to automatic operation of automatic test equipment due to the fact that the existing test probe is manually aligned with a test point. 本发明公开了一种气控测试探针，包括：针管；第一密封座，所述第一密封座设置在针管的一端，所述第一密封座内设置有进气口；针轴，所述针轴设置在针管内，针轴的一端从所述针管的另一端伸出；针轴的外壁上设置有限位圆台，针轴的另一端设置有第一密封圈；弹性件，所述弹性件套设在
