Abstract: A guiding grid is disclosed and includes plural circumferential elements and plural radial elements. The circumferential elements are disposed concentrically relative to a central axis, spaced apart from each other in a radial direction, and form different heights relative to a bottom surface. One of the circumferential elements forms a top height relative to the bottom surface, so that the circumferential elements are divided into an outer-ring region and a central region in the radial direction. The circumferential elements located in the central region are increased in height relative to the bottom surface along the radial direction. The circumferential element located in the outer ring region are reduced in height relative to the bottom surface along the radial direction. The radial elements are connected between each of two adjacent circumferential elements. At least one of the radial elements is misaligned and discontinuous in the radial direction.

Abstract: The present disclosure provides a motor including a stator, a rotor and a first circuit board. The stator includes a winding assembly including a plurality of coils. A conductive element is extended out from the winding assembly and is electrically connected to a first electrical connector. The first electrical connector penetrates through a pillow of the stator and is electrically connected to the first circuit board. The motor further includes a second circuit board, and the second circuit board is electrically connected to the first circuit board. The first electrical connector serves as a connector for electrically connecting the winding assembly to the first circuit board. The present disclosure has the advantage of easy installation by replacing the conventional wire binding plate with the first circuit board.

Abstract: The present disclosure provides a motor including a base, a stator and a rotor. The stator is disposed on the base. The base includes a cylinder. There is a flange disposed on a side of the cylinder neighboring to the rotor. Fins are axially disposed on the flange, and the periphery of the flange has a breach. The breach is partially extended to the cylinder, and there is also a plurality of fins disposed in the breach. A plurality of air-guiding members are annularly disposed on the periphery of the rotor. The air-guiding members are connected to each other through a connecting rim. The fins on the flange and the air-guiding members of the rotor are both extended axially, thus the interference therebetween is avoided. When the motor rotates, the air-guiding members are able to drive the flow passing through the breach for achieving heat-dissipating effect.

Abstract: A quick-operating adjustable wrench has a fixed jaw, a moveable jaw, and a handle. The fixed jaw has an abutting face, two mounting plates, and a mounting recess. The two mounting plates are formed on and protrude from the abutting face and are separate from each other, and the mounting recess is formed between the two mounting plates. The moveable jaw is pivotally connected to and abuts the fixed jaw, and has a pushing portion mounted in the mounting recess and abutting the fixed jaw. The handle is pivotally connected to the fixed jaw, abuts the movable jaw, and has a driving portion. The driving portion is pivotally connected to the fixed jaw and abuts the moveable jaw, and thereby the quick-operating adjustable wrench is applicable to nuts of different sizes. The structure of the quick-operating adjustable wrench is simplified, and may fasten fastening elements quickly.
