Abstract:
A controller assembly includes a housing, first and second tube units, and first and second runners. Each of the first and second runners slides on a respective one of the first and second tube units when the respective one of the first and second tube units is driven to rotate. In response to sliding of the first runner to bring the first runner into abutment with the second runner, the first runner is prevented from sliding over the second runner, whilst impeding rotation of the first tube unit. In response to sliding of the second runner to bring the second runner into abutment with the first runner, the second runner is prevented from sliding over the first runner, whilst impeding rotation of the second tube unit.
