Abstract
Abstract A quick-release device is used for a music support stand composed of a vertical rod and a boom rod. The quick-release device consists of a body, a locking block and a lever. The body has a head, a rod socket and a locking cavity. The head is adapted to attach to the boom rod of a music support stand. The rod socket is formed under the head to receive the vertical rod. The locking cavity is formed on the rod socket and has an inner space to communicate with an inner hole in the rod socket. The locking block is movably mounted inside the locking cavity, and the lever is pivotally attached to the body to press the locking block against the vertical rod or to release the locking block. The music support stand can be quickly attached or detached in an easy way.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
263 words
A quick-release device adapted to connect a vertical rod ( 50 ) to a boom rod ( 40 ) of a music support stand, the quick-release device comprising: a body ( 10 ) having a head ( 11 ) adapted to connect to the boom rod ( 40 ); a rod socket ( 13 ) with an outer periphery formed under the head ( 11 ) to adapt to receive the vertical rod ( 50 ); and a locking cavity ( 12 ) formed on the outer periphery of the rod socket ( 13 ) and having two sidewalls ( 122 ) and an inner space ( 123 ) defined ,by the sidewalls ( 122 ), wherein the inner space ( 123 ) further has a channel ( 14 ) with a transverse length communicating with a rod hole ( 131 ) in the rod socket ( 13 ); a locking block ( 30 ) movably mounted inside the channel ( 14 ) and having a transverse length slightly longer than the transverse length of the channel ( 14 ); and a lever ( 20 ) pivotally mounted inside the inner space ( 123 ) of the locking cavity ( 12 ) and having a pivot end ( 21 ) and a free end, wherein the pivot end; ( 21 ) is an eccentric head having a widened portion ( 202 ) to press against the locking block ( 30 ) to firmly attach to the vertical rod ( 50 ) when the lever ( 20 ) is pushed to a locked position.
Claim 2
Dependent Claim
263 words
A quick-release device adapted to connect a vertical rod ( 50 ) to a boom rod ( 40 ) of a music support stand, the quick-release device comprising: a body ( 10 ) having a head ( 11 ) adapted to connect to the boom rod ( 40 ); a rod socket ( 13 ) with an outer periphery formed under the head ( 11 ) to adapt to receive the vertical rod ( 50 ); and a locking cavity ( 12 ) formed on the outer periphery of the rod socket ( 13 ) and having two sidewalls ( 122 ) and an inner space ( 123 ) defined ,by the sidewalls ( 122 ), wherein the inner space ( 123 ) further has a channel ( 14 ) with a transverse length communicating with a rod hole ( 131 ) in the rod socket ( 13 ); a locking block ( 30 ) movably mounted inside the channel ( 14 ) and having a transverse length slightly longer than the transverse length of the channel ( 14 ); and a lever ( 20 ) pivotally mounted inside the inner space ( 123 ) of the locking cavity ( 12 ) and having a pivot end ( 21 ) and a free end, wherein the pivot end; ( 21 ) is an eccentric head having a widened portion ( 202 ) to press against the locking block ( 30 ) to firmly attach to the vertical rod ( 50 ) when the lever ( 20 ) is pushed to a locked position.
