Abstract:
A locking mechanism, a propeller (100) and an aircraft both having same are provided. The propeller (100) comprises a blade (20) and the locking mechanism, and the locking mechanism is used for locking the blade (20) and a driving shaft (10) relatively. The driving shaft (10) comprises a clamping arm (13) and a clamping groove (14) formed in the free end of the clamping arm (13). The locking mechanism comprises a locking part (40). The locking part (40) comprises a pressing part (41) and a clamping part (42) matched with the clamping groove (14), and the clamping part (42) is engaged with the clamping groove (14). The driving shaft (10) is locked on the blade (20). The pressing part (41) is slidably connected with the blade (20). When the pressing part (41) slides to the preset position relative to the blade (20), the clamping part (42) is separated from the clamping groove (14) to allow the separation of the driving shaft (10) from the blade (20). When the driving shaft (10) is locked on the blade (20), the driving shaft (10) will also not loose, and the propeller (100) using the locking mechanism is easy to detach.
