The invention provides a novel helicopter power-off self-locking electric harpoon landing assisting mechanism. The top of the harpoon landing assisting mechanism comprises a mounting pull rod, a rod end bearing, a rubber pad, a gearbox, a brushless motor and a power-off electromagnetic brake. The fish fork landing assisting mechanism middle part comprises a sleeve, a telescopic rod, a ball screw and a potentiometer; the lower end part of the fish fork landing assisting mechanism comprises an anchoring fork assembly; the threaded part of the rod end bearing is connected with the mounting pull rod, and a bolt penetrates through the gearbox and the rod end bearing to connect the gearbox and the rod end bearing; the rubber pad is mounted on the gear box, the gear box is driven by the brushless motor, and the brushless motor is connected with the power-off electromagnetic brake; the output end of the gearbox drives the ball screw to rotate, a ball screw nut is connected with an inner nut, and the inner nut is installed in the telescopic rod. The ball screw nut end cover is connected with a sliding block bolt of the potentiometer in an embedded mode, a sliding block of the potentiometer moves to feed back the position of the ball screw nut, and the device is simple in structure and easy to maintain.
