ABSTRACT:
The connecting device includes rotor and blade mounting segments each secured on a rotor and a fan blade at a respective connecting end thereof. A socket end of the rotor mounting segment extends in a radial direction relative to the rotor, and has an insert wall with an insert opening, an insert slot confined by upper and lower inner walls and extending in the radial direction from the insert opening, and an upper outer wall opposite to the upper inner wall. The upper outer wall has a recess communicated with the insert slot to form a retaining wall. A plug end of the blade mounting segment has a bottom wall to be fitted into the insert slot from the insert opening. A resilient retainer has a proximate end secured on the bottom wall, and a distal end with an engaging spring protrusion to provide a biasing force away from the bottom wall. The distal end can be brought to insert into the insert slot and to be kept in sliding contact with the upper inner wall against the biasing force until the engaging spring protrusion abuts against and is retained at the retaining wall of the socket end.
