This utility model discloses an adjuster for adjusting wheel spacing, including a first fixing plate with a first fixing hole on its surface. An inner connecting cylinder is fixedly connected to one side surface of the first fixing plate. An annular washer is slidably sleeved on one end of the outer surface of the inner connecting cylinder. An outer connecting cylinder is slidably sleeved on the outer surface of the inner connecting cylinder. A second fixing plate is fixedly connected to one end of the outer connecting cylinder. The second fixing plate has a second fixing hole on its surface. A central cylinder is fixedly connected to the middle position inside the inner connecting cylinder. The central cylinder has a threaded hole inside. A countersunk hole is provided on one side of the second fixing plate. A through hole is provided inside the countersunk hole. A combination screw is rotatably installed inside the through hole. The combination screw is threaded into the threaded hole, allowing for alignment and locking to ensure safety and stability, facilitating adjustment and use, and providing high adaptability.

This utility model relates to the field of bicycle quick-release technology and discloses a bicycle quick-release lever, comprising: a shaft mounted on the locking ring end side; a washer sleeved on the outer ring of the shaft; a dust cover snapped onto the locking ring end side; an installation ring installed inside the locking ring; a handle rotatably mounted on the outer ring of the installation ring; the mounting ring end side having an arc-shaped surface; an adjustment component provided on the outer ring of the installation ring; the adjustment component includes a rotating rod fixed to the side walls of both sides of the installation ring; a square block rotatably sleeved on the outer ring of the rotating rod; the square block being fixedly connected to the handle; and multiple arc-shaped grooves formed inside the handle. This quick-release lever allows for adjustment of the handle angle to find the most suitable operating posture when facing different bicycle component installation positions and operating spaces. It can easily handle both conventional and complex disassembly positions with obstructions, improving the applicability and practicality of the quick-release lever in various usage scenarios.

A device for lifting a wheel and rolling the wheel on a surface includes an elongated rigid plate having a top side, a bottom side, a peripheral edge, a pedal portion at a rear end of the rigid plate, and a wheel portion at a forward end of the rigid plate. A ground roller is fixed with the bottom side of the rigid plate and at least two wheel rollers are fixed with a top side of the wheel portion. In use, with the wheel resting on the wheel rollers, the pedal portion may be pressed downwardly to pivot the rigid plate about the roller to lift the wheel. The lifting device is then rolled on the surface to place the wheel at a desired position, and rotated until obtaining a desired rotational orientation.

The application discloses a cam device for wheel assembly conveying, which comprises a base, a driving structure and a conveying lifting structure, one end of the top surface of the base is fixed with a bearing seat, and the other end of the top surface is fixed with a driving support seat; the driving structure comprises a driving motor, a cam, a driving cylinder and a driving support rod; the driving motor is fixed on the side of the driving support seat, the cam is in the driving support seat and is fixed on the main shaft of the driving motor; the conveying lifting structure comprises a conveying frame, a connecting rod mechanism, a front crank arm structure and a rear crank arm structure; the connecting rod mechanism is connected between the conveying frame and the driving cam; the bottom ends of the front crank arm structure and the rear crank arm structure are connected with the driving support rod through a first shaft body. The cam and the connecting rod mechanism can realize the accurate intermittent motion of the conveying frame in a specific interval, the response speed and the motion precision are improved, and the driving cylinder cooperates with the front crank arm structure and the rear crank arm structure to realize the lifting of the conveying frame, and the use stability and reliability are improved.
