Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
The probe arm with the angle convenient to adjust as shown in the figures 1-3 comprises at least two damping rotating shafts and at least two connecting shafts which are hinged with each other; at least two damping rotating shafts and at least two connecting shafts are arranged alternately. The number of the damping rotating shafts and the connecting shafts can be determined according to the use environment of the probe arm. The damping rotating shafts and the connecting shafts are respectively two in the embodiment, the two damping rotating shafts keep an axial distance, one connecting shaft is located between the two damping rotating shafts, and the other connecting shaft is arranged at the other end of any one of the two damping rotating shafts. In fact, there may be three damping rotating shafts, there may be two connecting shafts, and one connecting shaft is arranged between every two damping rotating shafts.
The damping pivot and the connecting axle of this embodiment have two respectively, specifically do:
the damping rotating shaft comprises a first damping rotating shaft 1 and a second damping rotating shaft 2 which are coaxially arranged; a first connecting shaft 3 is arranged between the first damping rotating shaft 1 and the second damping rotating shaft 2; two ends of the first connecting shaft 3 are respectively hinged with the first damping rotating shaft 1 and the second damping rotating shaft 2; one end of the first damping rotating shaft 1 or the second damping rotating shaft 2 back to the first connecting shaft 3 is also hinged with a second connecting shaft 4. Two ends of the first connecting shaft 3 are respectively provided with a first hinge bolt 5; the first damping rotating shaft 1 and the second damping rotating shaft 2 are respectively hinged with the first connecting shaft 3 through a first hinge bolt 5. The central axes of the two first hinge bolts 5 are parallel and perpendicular to the central axis of the first damping rotating shaft 1 or the central axis of the second damping rotating shaft 2.
