A collapsible golf push cart includes a main frame having an upper frame, a lower frame, a rear wheel frame and two rear wheels rotatably mounted to the rear wheel frame respectively, at least a joint mechanism having at least a first joint member and at least a second joint member, the first and second joint members being connected with the lower and upper frames respectively, and a clasp member having a male clasp and a female clasp engaging with the first and second joint members respectively. The male clasp defines a block and a control mechanism for controlling the block, and the female clasp defines a notch to accommodate the block. The control mechanism causes the block to extend or retract to fix or release the clasp member for making the golf push cart in an extended or a collapsed position.

What is claimed is: 1. A golf push cart, comprising: a main frame comprising an upper frame, a lower frame, a rear wheel frame, and two rear wheels rotatably mounted to the rear wheel frame respectively; at least a joint mechanism comprising at least a first joint member and at least second joint member, the first and second joint members connecting with the lower and the upper frames respectively; and a clasp member comprising a male clasp and a female clasp engaging with the first and the second joint members respectively, the male clasp including a block and a control mechanism for controlling the block, and the female clasp including a notch to accommodate the block, wherein the control mechanism causes the block to extend to fix or retract to release the clasp member for making the golf push cart in an extended position or a collapsed position, wherein the male clasp further comprises a spring, the spring abuts the block to extend out of the first joint member, the control mechanism comprises a bolt, and a pivot mechanism engaged with the bolt and the block, the bolt rotates to cause the pivot mechanism to drive the male clasp induce the block to retract back into the joint member via pressing on the spring, the bolt being set free causes the spring be released to abut the block to extend out of the first joint member again, and, wherein the control mechanism includes a handle mechanism for making the golf push cart in the extended position or the collapsed position, which includes a handle, and a stopper nested in an end portion of the handle, the stopper includes an elastic element and an abutting element, both the handle and the stopper respectively include a through hole, and the bolt is inserted into the through holes of the handle and the stopper and abutting by the elastic element and the abutting element, which is steadily relative to the handle. 2. The golf push cart as claimed in claim 1, wherein the bolt includes a connecting bar, the pivot mechanism includes a through hole, and the connecting bar is inserted into the through hole to make the bolt engage with the pivot mechanism. 3. The golf push cart as claimed in claim 1, wherein the pivot mechanism includes a pivot portion, and the block includes a notch to accommodate the pivot portion. 4. The golf push cart as claimed in claim 1, wherein the bolt includes a notch thereof, and the abutting element includes a tenon pressed on the notch. 5. The golf push cart as claimed in claim 1, wherein the rear wheel frame is engaged with the joint mechanism via a connecting member, which includes a first pivot piece, a second pivot piece disposed opposite to the first pivot piece, and a blocking member disposed between the first and the second pivot pieces, the blocking member is disposed between the first and the second joint members while the connecting member engages with the joint mechanism. 6. The golf push cart as claimed in claim 1, wherein each of the first and the second joint members includes a joint portion for respectively engaging with the lower and the upper frames. 7. The golf push cart as claimed in claim 1, further comprising a front wheel, rotatably mounted to an end portion of the lower frame.
