A quick-release fixing structure for a fender of a bicycle is provided with a mounting member fixed to the front fork, an engaging member fixed on the fender, and a U-shaped control member. The mounting member is formed with an elastic piece, a receiving cavity, and two penetrating holes which have two cutting grooves in communication with the receiving cavity and the penetrating holes. The engaging member is received in the receiving cavity of the mounting member and formed with two arc-shaped cutting grooves for mating with the arc-shaped cutting grooves of the mounting member. The control member is inserted in the penetrating holes and formed with two arc-shaped grooves. The quick-release fixing structure is capable of assembling the fender onto the front fork of bicycle or disassembling it therefrom by a simple pressing operation.

1. A quick-release fixing structure of a bicycle; comprising: a fender;a front fork;a mounting member having a top surface pressed against an abutting edge at an end of the front fork, in a bottom of the mounting member being formed a receiving cavity whose axial direction is defined as a longitudinal direction, and the mounting member being formed around its periphery with two penetrating holes which penetrate through the periphery of the mounting member to leave two cutting grooves on an inner surface of the receiving cavity, and the cutting grooves being in communication with the receiving cavity and the penetrating holes, an axial direction of the penetrating holes being defined as a transverse direction, an elastic piece extending from the mounting member, and a bolt which extends in the longitudinal direction being inserted through the receiving cavity and screwed with a tightening device, in a bottom of the receiving cavity being formed a tapered hole tapering toward the front fork, the mounting member being formed around its periphery with two opposite arc-shaped surfaces, the penetrating holes penetrating through the arc-shaped surfaces, the elastic piece extending from an end of one of the arc-shaped surfaces of the mounting member, and the bolt being inserted through the receiving cavity and screwed with the tightening device;an engaging member received in the receiving cavity of the mounting member and formed around its periphery with two arc-shaped cutting grooves for mating with the arc-shaped cutting grooves of the mounting member; andan U-shaped control member provided with a pressing section and two engaging sections at both ends of the pressing section, the engaging sections of the control member being inserted in the penetrating holes, each of the engaging sections being formed on an inner surface thereof facing the engaging member with an arc-shaped groove for mating with the cutting groove of the mounting member, the elastic piece of the mounting member being capable of pressing against the pressing section of the control member to make the arc-shaped grooves of the control member misaligned with the cutting grooves of the mounting member, so that the engaging member is engaged with the mounting member, or make the arc-shaped grooves of the control member aligned with the cutting grooves of the mounting member, so that the engaging member is disengaged from the mounting member, the pressing section being formed in the middle of the control member, each of the engaging sections being formed at an end thereof with a positioning protrusion, so that when the engaging sections are inserted in the penetrating holes, the positioning protrusions are pressed against an outer edge of the penetrating holes; andthe fender being fixed to the end of the front fork, and the engaging member being disposed on the fender;wherein the tightening device is fixed by pressing against an inner surface of the front fork and comprises a clamping sleeve and a tightening member:the clamping sleeve which extends in the longitudinal direction is mounted on the top surface of the mounting member and includes an open end and a connecting end, the clamping sleeve is formed with a plurality of longitudinal slots extending from the open end, and a plurality of elastic pieces arranged between the longitudinal slots;the tightening member is inserted in the open end of the clamping sleeve and includes a big-diameter end, a small-diameter end and a conical surface between the big-diameter end and the small-diameter end, the tightening member is further provided with a locking hole penetrating from the big-diameter end to the small-diameter end, the tightening member has its small-diameter end inserted in the open end of the clamping sleeve, the bolt is inserted through the tapered hole of the mounting member, the clamping sleeve, the locking hole of the tightening member and then screwed with a nut, and the elastic pieces are pushed to press against the inner surface of the front fork by the conical surface of the tightening member. 2. The quick-release fixing structure of a bicycle as claimed in claim 1, wherein each of the elastic pieces is formed on its inner surface with a plurality of transverse ribs for engaging with a plurality of transverse grooves formed in the tightening member. 3. The quick-release fixing structure of a bicycle as claimed in claim 1, wherein a polygonal protrusion is formed in a center of the top surface of the mounting member, and at the connecting end of the clamping sleeve is formed a polygonal hole for engaging with the polygonal protrusion of the mounting member. 4. The quick-release fixing structure of a bicycle as claimed in claim 1, wherein each of the engaging sections is formed at an end thereof with a clamping slot. 5. The quick-release fixing structure of a bicycle as claimed in claim 1, wherein the fender is provided with a circular connecting portion, the engaging member is fixed to the fender by an engaging disc, the engaging member is provided around its lower edge with a plurality of protrusions, the engaging disc is formed at its bottom with an assembling space, and further formed in its top surface with a plurality of holes in communication with the assembling space, the protrusions of the engaging member are engaged in the holes of the engaging disc. 6. The quick-release fixing structure of a bicycle as claimed in claim 5, wherein each of the holes of the engaging disc is formed an L-shaped engaging block, the connecting portion is formed with a plurality of arc-shaped cavities, and at both ends of each of the arc-shaped cavities are formed with an inner wall and an opening, the engaging blocks of the engaging disc are received in the arc-shaped cavities and engaged in the openings of the arc-shaped cavities. 7. The quick-release fixing structure of a bicycle as claimed in claim 1, wherein the mounting member is further formed on its periphery with a flat surface located corresponding to the elastic piece, and at a conjunction between the elastic piece and the mounting member is formed a deformable portion, the elastic piece is pressed against the flat surface. 8. The quick-release fixing structure of a bicycle as claimed in claim 1, wherein the receiving cavity is formed around its inner surface with two opposite arc-shaped surfaces and two opposite restricting surfaces, the engaging member is formed around its periphery with two opposite arc-shaped surfaces and two opposite positioning surfaces and received in the receiving cavity of the mounting member in such a manner that the two arc-shaped surfaces and the two positioning surfaces of the engaging member are aligned with the two arc-shaped surfaces and the restricting surfaces of the mounting member, respectively.
