  • Adjustable connector for a lawn rake
    Patent number: 7134264
    Abstract: An adjustable connector for a lawn rake has a sleeve, a rake head and a lever. The rake head is connected in front of the sleeve. The lever is attached pivotally to the sleeve and has a cam head operationally pressing against a shaft of the lawn rake when the lever is pivoted to lock the handle in the sleeve. By directly pressing the cam head of the lever against the handle, other accessories such as separate compression clamps in the prior art are obviated so that the structure of the adjustable connector is simplified.
