Cantilever supporting injection oil supply device

The invention discloses a cantilever support jet oil supply device, which adopts a flexible first oil supply pipe to supply oil, can adapt to different experiment requirements by adjusting the torsion posture of the first oil supply pipe and adjusting the jet angle of a nozzle, does not need to repeatedly design an oil supply pipeline, reduces the repeated design, and reduces the structural complexity. In addition, the height of the support is adjustable so as to adapt to the adjustment of the height of the first oil supply pipe, so that the cantilever supporting injection oil supply device is suitable for injection lubrication of bearings with different sizes. The nozzle is flexibly adjusted through the flexible first oil supply pipe and the height-adjustable support, so that directional oil supply to a to-be-lubricated part is achieved, the length of an oil supply runner is shortened, the oil supply pressure is reduced, and the oil leakage phenomenon is avoided. In addition, the cantilever supporting inject
