Abstract
A ball-clamping control handle structure for a vehicle carrier includes a fixed base, a control handle, and a control unit. The fixed base houses a ball-clamping assembly for holding a trailer ball and has a shaft connection at its upper end. The control handle is shaft-connected to the shaft connection of the fixed base, controlling the clamping or releasing of the ball-clamping assembly. The control unit is located at the front end of the main member and has a hollow structure and an inclined surface. A window on the inclined surface displays the locking status of the hook. The hook is driven by a locking cylinder, and its engaging end can be fixed or detached from the positioning part of the fixed base. When the hook is locked, the display surface is visible in the window, confirming the fixed status. When the locking cylinder is rotated to unlock, the engaging end of the hook disengages from the positioning part, the display surface is no longer visible in the window, and a torsion spring causes the hook to rebound, facilitating subsequent operations. Through the window design and spring rebound mechanism, the safety and convenience of the fixing mechanism are improved, making it suitable for the quick installation and removal of trailer balls.
