A fan blade assembly includes multiple blades sandwiched between a base and a cap. The base has a hollow shaft and has multiple mounting slots, positioning tubes and fixing holes. Each of the blades has a mounting seat having two lugs. The lugs of any two adjacent blades are inserted into the respective mounting slot. The mounting seat has at least one first through hole to allow insertion of the respective positioning tube, and has at least one second through hole. The cap has a mounting sleeve mounted on the shaft, multiple positioning posts each inserted into the respective first through hole and multiple threaded tubes each inserted into the respective second through hole. The fan blade assembly also includes multiple fastening screws each extended through the respective fixing hole and each screwed into the respective threaded tube.

A motor overcurrent protection device connectable to a motor. The motor has a rotary shaft and a controlling port. The motor overcurrent protection device includes a sensing unit, a driving unit and a controlling unit. The sensing unit includes a magnetic block arranged on a circumference of the rotary shaft and a Hall device positioned beside the rotary shaft. The magnetic block is rotatable along with the rotary shaft to be instantaneously aligned with the Hall device. The driving unit is electrically connected with the controlling port of the motor. The controlling unit is electrically connected with the sensing unit and the driving unit. When the motor operates, each time the magnetic block is aligned with the Hall device, the Hall device outputs a pulse signal which is stored in the controller of the controlling unit. All the pulse signals are summed up in a preset sensing time of the controller. In the case that the sum does not exceed a standard rotational speed value, the controlling unit via the driving unit will stop the motor from operating so as to protect the motor from malfunctioning due to rising of current.

A stroller includes a wheeled stroller frame with a handle unit for pushing the stroller frame, and a seat member mounted on the stroller frame. The stroller frame has a pair of horizontal linking plates on two sides of the seat member. A shock absorbing device includes a frame unit disposed between the linking plates and mounted swingably on the linking plates, and a spring unit. The frame unit is movable relative to the linking plates in a first direction, wherein the frame unit swings forwardly and downwardly, and in a second direction, wherein the frame unit swings rearwardly and upwardly. The spring unit interconnects the frame unit and the linking plates and biases the frame unit in the second direction. The seat member has a seat portion with a bottom side that is provided with a mounting unit for mounting the seat member on the frame unit of the shock absorbing device.
