Abstract: A motor assembly structure including a first bracket and a second bracket which together form a coil unit. The first bracket has a hub integrally extending from the first bracket into the second bracket. The motor assembly structure further includes a silicon steel plate unit fitted around the hub and sandwiched between the first bracket and the second bracket. The first bracket and the hub are integrally formed as a module so that the assembling procedure of the motor assembly structure is facilitated.

Abstract: A heat dissipating fan has a round disk. The bottom of the round disk has a receiving portion concave upwards for receiving a motor 14. A periphery of the round disk has a plurality of cambered extending blades which are arranged regularly. The plurality of blades extends along a cambered path. Each blade has a convex surface and a concave surface. Each convex surface has a protruding flow guide opposite to the concave surface of the blade; and at a connection of the flow guide and the blade has at least one cambered surface.

Abstract: A winder of fishing rod, including a housing, a reel unit and a linking mechanism. A sleeve of the linking mechanism is fitted with a mandrel of the reel unit which is drivingly connected with the reel. An engaging member of the sleeve is reciprocally movable within the travel grooves of the mandrel. The entire sleeve can share the force exerted onto the mandrel so as to ensure the engagement between the engaging member of the sleeve and the travel grooves. Therefore, the engaging member is guided by the sleeve to smoothly move and make the fishing line evenly wound on the reel unit.
