A device for locking a rod member is provided. The device includes a body section having a vertical hole therein, and a ring-type locking unit and a piston serially arranged along the hole, wherein the rod member is disposed in the hole to be axially movable through the locking unit and the piston. The locking unit may be a lock block including an outer ring having an inclined surface on one side thereof, thereby defining a wedge-type space, an inner ring coaxially disposed in one side of the outer ring and accommodating a pressurizing member interacting with the inclined surface, and a spring disposed in the other side of the outer ring so as to elastically connect the outer ring and the inner ring.

The present disclosure provides a knob device for vehicle which includes a knob unit and a locking unit. The knob unit includes a rotating cover, a rotary shaft and a motor configured to drive the rotating cover to vibrate. The locking unit includes a rotary wheel which includes a main body fixed to the rotary shaft and locking teeth formed at a periphery of the main body. The locking tooth includes a first end, a second end and a surface connecting the first end and the second end. A distance between the first end and the central axis of the rotary wheel is greater than a distance between the second end and the central axis. The locking unit further includes a locking pole configured to abut the first end to limit rotation of the rotary wheel clockwise, and an actuator configured to drive the locking pole to move.

An adjustable clamping mechanism for a throttle control device on a handlebar of a vehicle includes a throttle lever and a clamp assembly that retains the throttle control device at a desired angular position upon said handlebar. The clamp assembly includes a body having a main section and a secondary section, the secondary section being disposed in a slot of the main section. A clamping member provides a clamping force upon the main section and secondary section. In an engaged position of the clamping member, the clamping member provides a clamping force to retain the throttle lever in a predetermined angular orientation upon said handlebar during operation of said vehicle. In a disengaged position of the clamping member, the clamping member does not provide the clamping force in order to permit the throttle lever to rotate about a longitudinal axis of said handlebar.
