Oblique beam type longitudinal-torsional compound vibration switching device

The invention discloses an oblique beam type longitudinal-torsional compound vibration switching device. The oblique beam type longitudinal-torsional compound vibration switching device comprises an upper tool head, oblique beams, a double-end stud, a middle connecting section and a lower tool head. The upper tool head, the middle connecting section and the oblique beams are matched in an inserted-connection abutting mode. An axial connection mechanism is arranged between the upper tool head and the lower tool head to realize tight combination of the whole device. The oblique beam type longitudinal-torsional compound vibration switching device is reasonable in design, simple in structure, capable of realizing connection of workpieces easily and high in practicability; by means of the device, output of longitudinal-torsional compound vibration of a one-way longitudinal vibration transducer can be realized.
