Patent attributes
The present disclosure discloses a fixed quick-release apparatus. It includes: a gear turntable, configured to connect a cycling bracket, where a limiting gear ring is disposed on a top circle of the gear turntable; a housing, configured to mount the gear turntable; and a gear stand, mounted inside the housing, where a positioning gear ring that is opposite to the limiting gear ring is disposed on a bottom circle of the gear stand, an anti-rotation plate is disposed at a top of the gear stand, and a limiting spring, disposed at a bottom of the gear stand. Because the gear stand is driven to move by pressing the button, the positioning gear ring is engaged with the limiting gear ring, to limit rotation of the locking turntable and the unlocking of the anti-rotation plate on the terminal device. Because the spring steel beads abut against the arc-shaped groove, the terminal device can be adjusted and positioned by rotating 360°.
