A modularized assembly structure of a wheelchair includes two upper transverse tubes and two lower transverse tubes mounted between a pair of sided front module connecting members and a pair of sided rear module connecting members, thereby forming the main frame of the wheelchair. The front wheel and the rear wheel may be respectively mounted on the upper and lower transverse tubes which may be set at different horizontal positions and different vertical heights, so that the distance between the front wheel and the rear wheel may be adjusted arbitrarily.

1. A modularized assembly structure of a wheelchair, comprising:a pair of sided front module connecting members each including a first insertion connector for insertion of an upper transverse tube, a second insertion connector for insertion of a lower transverse tube, and at least one front wheel locating screw bore for locating a front wheel; and,a pair of sided rear module connecting members each including a fourth insertion connector corresponding to the first insertion connector for insertion of the upper transverse tube, a fifth insertion connector corresponding to the second insertion connector for insertion of a lower transverse tube, and at least one rear wheel axle insertion hole for insertion of a rear wheel axle;wherein each of the sided front module connecting members has multiple front wheel locating screw bores which are arranged at different horizontal positions and different vertical heights, and the front wheel is selectively located by one of the multiple front wheel locating screw bores. 2. A modularized assembly structure of a wheelchair, comprising:a pair of sided front module connecting members each including a first insertion connector for insertion of an upper transverse tube, a second insertion connector for insertion of a lower transverse tube, and at least one front wheel locating screw bore for locating a front wheel; and,a pair of sided rear module connecting members each including a fourth insertion connector corresponding to the first insertion connector for insertion of the upper transverse tube, a fifth insertion connector corresponding to the second insertion connector for insertion of a lower transverse tube, and at least one rear wheel axle insertion hole for insertion of a rear wheel axle;wherein each of the sided rear module connecting members is formed with at least one pin hole, so that a handle structure may be selectively and pivotally mounted on the pin hole by a pin. 3. The modularized assembly structure of a wheelchair in accordance with claim 2, wherein the handle structure includes a pivotable connecting seat having a bottom mounted on one of the sided rear module connecting members, and a push bar extension bracket mounted on the connecting seat, the connecting seat is formed with a plurality of pin holes, the push bar extension bracket has a first end provided with a push bar and a second end provided with a block, the block of the push bar extension bracket has a top pivotally mounted on a top of the connecting seat by a spindle, and a bottom for insertion of a fixing pin which is selectively inserted into one of the pin holes of the connecting seat. 4. The modularized assembly structure of a wheelchair in accordance with claim 3, wherein the connecting seat has a front end provided with a fixing lug for locking a first end of a foot plate extension bracket whose second end is provided with a foot plate, and a pad is secured on the upper transverse tube for supporting the foot plate extension bracket. 5. A modularized assembly structure of a wheelchair, comprising:a pair of sided front module connecting members each including a first insertion connector for insertion of an upper transverse tube, a second insertion connector for insertion of a lower transverse tube, at least one front wheel locating screw bore for locating a front wheel, a pad mounted on the upper transverse tube; and,a pair of sided rear module connecting members each including a fourth insertion connector corresponding to the first insertion connector for insertion of the upper transverse tube, a fifth insertion connector corresponding to the second insertion connector for insertion of a lower transverse tube, and at least one rear wheel axle insertion hole for insertion of a rear wheel axle;wherein the pad includes two connecting pieces connected with each other by bolts and nuts, thereby forming a substantially Y-shaped structure, and each of the two connecting pieces is formed with multiple locking holes f or locking the upper transverse tube. 6. A modularized assembly structure of a wheelchair, comprising:a pair of sided front module connecting members each including a first insertion connector for insertion of an upper transverse tube, a second insertion connector for insertion of a lower transverse tube, at least one front wheel locating screw bore for locating a front wheel, a pad mounted on the upper transverse tube; and,a pair of sided rear module connecting members each including a fourth insertion connector corresponding to the first insertion connector for insertion of the upper transverse tube, a fifth insertion connector corresponding to the second insertion connector for insertion of a lower transverse tube, and at least one rear wheel axle insertion hole for insertion of a rear wheel axle;wherein the pad has a top provided with a loop-shaped cover member.
