摘要： A clutch structure that includes a motor to directly drive a rotary disc of an actuation unit, and the actuation unit further directly act on a push unit, so as to achieve reduction of size. Further, the push unit has a spring holder that drives a push bracket to press against a clutching unit, and the push bracket and the clutching unit are rotatably in synchronization with each other and a group of balls is arranged between the push bracket and the spring holder, such that smooth rotation can be maintained even during the process of pressing to thereby effectively reduce pause and setback incurring in coupling and connection and also to efficiently establish a transmission clutching force to have the operability not affected by the delay.

摘要： A coupling structure includes a shaft, a tube, and a connection assembly. An end of the shaft is formed with a plurality of axial insertion troughs extended in an axial direction and arranged in an alternate manner. The tube includes a penetration-axle hole formed in a center thereof and corresponding to the penetration-axle section of the shaft. A plurality of radial insertion troughs, in the form of a recessed surface, are formed in an inner circumferential surface of the penetration-axle hole of the tube. The connection assembly includes a coupling block that has an outer circumference formed with a plurality of radial insertion blocks corresponding to the radial insertion troughs of the tube and a plurality of axial insertion blocks corresponding to the axial insertion troughs of the shaft, so that a fastening member may be used to selectively fasten the coupling block between the shaft and the tube.

摘要： An electric device for a bicycle has a casing, a pedal shaft, a motor shaft, a rotor assembly, a stator assembly, a gear assembly, a chain wheel and a control unit. Because a normal of the circuit board of the control unit is parallel to the motor shaft, the circuit board can be axially adjacent to a side surface of the rotor assembly to detect the rotor assembly. Thus, one single circuit board can detect the rotor assembly as well as maintain electric connection with other components, thereby saving space and reducing the volume of the casing. As the casing has a reduced volume, interference with the rear wheel can be avoided.

摘要： A straw-loosening-prevention lid has a body and a straw part. The straw part has a through hole, multiple abutting fins, a straw hole, a closing flake and multiple connecting contacts. Since the straw hole is surrounded by the abutting fins, a diameter of the straw hole can be smaller than a diameter of a straw. When the straw is inserted downward into the straw hole, the abutting fins are pushed by the straw, are bent downward and then clamp the straw. Afterward, when the straw is going to move upward, the friction force between the straw and the abutting fins makes the abutting fins bend upward to the original angle and clamp the straw more tightly. As a result, the straw clamped by the abutting fins is hard to move upward, which prevents the straw from slipping out easily.
摘要翻译： 秸秆防松盖具有主体和秸秆部分。 秸秆部分具有通孔，多个邻接翅片，吸管孔，闭合片和多个连接接点。 由于吸管孔被邻接的翅片包围，吸管孔的直径可以小于吸管的直径。 当秸秆向下插入吸管孔时，相邻的翅片被秸秆推动，向下弯曲，然后夹紧吸管。 之后，当吸管向上移动时，吸管与邻接翅片之间的摩擦力使得邻接的翅片向上弯曲到原来的角度，并且更紧密地夹紧吸管。 结果，被邻接的翅片夹紧的秸秆难以向上移动，从而防止吸管容易滑落。

摘要： A wiring frame, a motor stator, and a motor applying them are disclosed. The wiring frame is formed of an annular tray structure. A top surface of the wiring frame is formed, from inside to outside, with at least three guide channels that correspond, in number, to phases and are separated from each other. Further, the wiring frame includes a plurality of through holes, which communicate inside and outside, respectively formed in bottoms of the guide channels. As such, at least three conductive wires are allowed to extend through the through holes in the bottom of the wiring frame directly into the corresponding ones of the guide channels for winding, so as to ensure that the conductive wires of different phases are separated from each other to eliminate erroneous contact therebetween and thus enhance operation safety. The outside diameter and height of the wiring frame are reduced.

摘要： A three-stage speed-change mechanism includes a casing in an interior of which a drive assembly, an input assembly, and an output assembly are arranged. The input assembly includes a transmission shaft driven by the drive wheel. An initial transmission wheel is mounted no a middle section of the transmission shaft. A first speed-change assembly and a second speed-change assembly are respectively arranged on two sides of the initial transmission wheel. The output assembly includes an output shaft, which is provided with an initial driven wheel and first and second speed-change wheels respectively mating the initial transmission wheel and the first and second speed-change assemblies. The initial driven wheel and the first speed-change wheel are respectively mounted by a first one-way bearing and a second one-way bearing on the output shaft. As such, a three-stage speed-change function is realized.
