摘要： A quick-release structure includes a fork, a clamping unit, and a quick-release unit. The fork has a receiving space. The clamping unit includes a base, a plurality of arc-shaped clamping members, an elastic ring, and a shaft cover. The base is fixed in the receiving space. The base has a circular cavity. The circular cavity is provided with a plurality of elongated grooves. The arc-shaped clamping members each have a first axle to slide in a corresponding one of the elongated grooves and a second axle. A center of the arc-shaped clamping members is formed with an adjustable clamping opening. The shaft cover is formed with a plurality of axle grooves arranged annularly. The second axles of the arc-shaped clamping members are pivotally connected to the respective axle grooves. The quick-release unit has a shaft. After the shaft passes through the adjustable clamping opening, the adjustable clamping opening subjected to the elastic force of the elastic ring is retracted to clamp the shaft.

摘要： A fastening structure includes a circular sleeve and a coupling member. One end of the circular sleeve has a receiving trough. A bottom of the receiving trough is provided with a first magnetic member. A wall of the receiving trough is provided with a protruding post. At least one guide groove is formed on an outer wall of one end of the coupling member. One end of the guide groove is an open axial groove having an opening. Another end of the guide groove is a closed axial groove having a stop end. The guide groove has a transverse groove between the open axial groove and the closed axial groove. Another end of the coupling member is a pivot end that has a central passage extending inwardly. A second magnetic member is disposed in the central passage. The first and second magnetic members have repulsive magnetic poles.

摘要： A quick-release structure includes a shaft and a driving assembly. Two ends of the shaft have a receiving hole and a connecting hole, respectively. The driving assembly includes a rotating handle and a connecting rod. One end of the rotating handle is provided with an end cap. The connecting rod includes a pivoting end and a driving section. The rotating handle is pivotally connected to the pivoting end of the connecting rod so that the rotating handle can be pivoted relative to one side of the connecting rod. When in use, the driving section is engaged in the connecting hole, and the rotating handle can be turned to drive the shaft to rotate; when not in use, the driving assembly is inserted into the receiving hole, and the end cap is pressed against an outer end of the receiving hole to be positioned.

摘要： A quick-release device for a bicycle includes a shaft having a locking assembly at one end and an inner sleeve in another end. The inner sleeve is kept a distance apart from an end edge of a through hole of the shaft to form an inner annular trough portion at an outer end of the through hole. A threaded cylinder is insertedly connected to the inner annular trough portion. A perforation is defined in the threaded cylinder. One axial end of the threaded cylinder has a cylindrical flange. The cylindrical flange is insertedly connected to the inner annular trough portion of the shaft. A bolt is insertedly disposed in the perforation of the threaded cylinder. The bolt passes through the perforation and is inserted into the shaft to be screwed to the inner sleeve, so that the bolt presses and locks the threaded cylinder and the shaft.
