A quick release attachment for a bicycle includes an attachment device, a bracket and a quick release assembly. The attachment device has a main connecting body. The main connecting body has a retaining groove. The bracket has a sub connecting body. The bracket has a connecting portion defined at one lateral side thereof. The connecting portion has an opening defined therethrough. The quick release assembly has a quick release member and an abutting block. The quick release member is assembled with the connecting portion and defines a tightening position and a releasing position. The abutting block is received in the opening of the bracket. When the pivot portion is on the tightening position, the abutting block is engaged with the retaining groove of the main connecting body so that the attachment device is secured to the bracket.

1. A quick release attachment for a bicycle comprising: an attachment device having a main connecting body defined at a lower portion thereof, the main connecting body having a retaining groove defined at one lateral sided thereof;a bracket assembled on a bicycle, the bracket having a sub connecting body corresponding to the main connecting body, the bracket having a connecting portion defined at one lateral side thereof, the connecting portion of the bracket having an opening defined therethrough and communicating with the retaining groove of the main connecting body; anda quick release assembly having a quick release member and an abutting block, the quick release member having a pivot portion and a grip portion, the pivot portion assembled with the connecting portion of the bracket pivotally, the pivot portion defining a tightening position and a releasing position, the pivot portion pivoted between the tightening position and the releasing position via the grip portion, the abutting block received in the opening of the bracket, the abutting block having a first abutting end and a second abutting end defined at two ends thereof respectively, the first abutting end abutting against the pivot portion, the second abutting end inserted into the opening of the bracket, the pivot portion defining an axis at a center thereof;wherein, when the pivot portion is on the tightening position, a distance between the axis and the first abutting end of the abutting block is larger than another distance between the axis and the first abutting end of the abutting block as the pivot portion is on the releasing position. 2. The quick release attachment for a bicycle as claimed in claim 1, wherein the connecting portion of the bracket further has two convex ears, the two convex ears having two through holes defined therethrough respectively; the opening is disposed between the two convex ears of the connecting portion; the pivot portion of the quick release member is assembled between the two convex ears; the pivot portion of the quick release member has a pivot hole defined therethrough. 3. The quick release attachment for a bicycle as claimed in claim 2, wherein the quick release assembly has an adjusting assembly, the adjusting assembly having a first adjusting member and a second adjusting member, the first adjusting member having a first head and a first shank, the second adjusting member having a second head and a second shank; the first shank and the second shank both have an enlarging section and a narrow section; the enlarging section of the first shank is adjacent to the first head, and the narrow section of the first shank is adjacent to the enlarging section; the enlarging section of the second shank is adjacent to the second head, and the narrow section of the second shank is adjacent to the enlarging section. 4. The quick release attachment for a bicycle as claimed in claim 3, wherein the first adjusting member and the second adjusting member both have an inclined surface defined between the enlarging section and the narrow section; the inclined surfaces of the first adjusting member and the second adjusting member are respectively abutted against two sides of the pivot hole. 5. The quick release attachment for a bicycle as claimed in claim 4, wherein the first shank of the first adjusting member and the second shank of the second adjusting member respectively pass through the two through holes of the two convex ears and are inserted into the pivot hole of the quick release member; the first adjusting member and the second adjusting member are coupled with each other, wherein the narrow sections are disposed in the pivot hole of the quick release member and the enlarging sections are disposed out of the pivot hole; when the first adjusting member and the second adjusting member are adjusted toward each other, the enlarging sections of the first adjusting member and the second adjusting member compress an inner wall of the pivot hole of the quick release member so as to press the pivot portion to abut against the first abutting end of the abutting block. 6. The quick release attachment for a bicycle as claimed in claim 3, wherein the first shank of the first adjusting member has an external thread section defined at one end thereof; the second shank of the second adjusting member has an internal thread section defined in an inner periphery thereof; the external thread section of the first adjusting member corresponds to the internal thread section of the second adjusting member; the external thread section of the first adjusting member is screwed into the internal thread section of the second adjusting member. 7. The quick release attachment for a bicycle as claimed in claim 1, the opening of the bracket has a first opening and a second opening, the second opening defined in a bottom of the first opening and communicating with the first opening; the first opening is larger than the second opening to form a shoulder between the openings; the second abutting end of the abutting block passes through the second opening; the first abutting end of the abutting block is received in the first opening and abuts against the shoulder. 8. The quick release attachment for a bicycle as claimed in claim 1, wherein the sub connecting body has a positioning groove defined therein; the main connecting body is slid into the positioning groove of the sub connecting body and positioned in the positioning groove. 9. The quick release attachment for a bicycle as claimed in claim 1, wherein the attachment device has a cover member and an assembling base; the main connecting body is disposed under the assembling base and the cover member is assembled on a top side of the assembling base; the assembling base has two clamping grooves defined at the top side thereof; the cover member has another two clamping grooves defined at one side thereof and corresponding to the two clamping grooves of the assembling base. 10. The quick release attachment for a bicycle as claimed in claim 1, wherein the attachment device has a threaded hole defined therethrough; a screw member passes through the threaded hole of the attachment device from the connecting body to the cover member and secured; a bicycle attachment is assembled on a terminal end of the crew member.
