Abstract
A transmission mechanism includes an adaptor configured to be connected to a power device, an output member engaged with the adaptor through a relative movement along an axial direction of the output member and configured to output a power of the power device transmitted by the adaptor to the output member, and a locking member rotatably provided on the output member and passing through the output member along the axial direction of the output member. The locking member includes an operating portion configured to connect the locking member with the adaptor to limit the relative movement along the axial direction or disconnect the locking member from the adaptor. The adaptor is configured to drive the output member to rotate coaxially with the adaptor to output the power. A relative rotation between the adaptor and the output member is limited by an engagement between the adaptor and the output member.
