BACKGROUND OF INVENTION [0001] 1. FIELD OF INVENTION [0002] The present invention relates to a pump. [0003] 2. RELATED PRIOR ART [0004] Referring to FIG. 12, there is shown a conventional pump. The conventional pump includes a cylinder 1' for containing a piston, a rod 6 connected to the piston, a handle 3 connected to the rod 6, a pipe 2' connected to the cylinder 1' and a nozzle 4 connected to the pipe 2'The nozzle 4 is for engagement with a valve installed on a tire 5 so that air can be pumped into a tire of a bicycle for example. For the convenience of the storage of the pump, the cylinder 1' and the pipe 2' are both short. In use, the pump must however be positioned very close to the tire of the bicycle, and this is inconvenient. [0005] Therefore, the present invention is intended to obviate or at least alleviate the problems encountered in prior art. SUMMARY OF INVENTION [0006] According to the present invention, a pump includes a piping and a pumping device. The pumping device includes a cylinder connected to the piping, a piston positioned in the cylinder, a rod connected to the piston, a ring connected to an end of the cylinder in order to retain the piston in the cylinder, a first holder connected to the rod in order to hold the piping, a handle pivotally connected to the first holder between an idle position and an active position and a second holder connected to an opposite end of the cylinder in order to hold the piping. [0007] The primary advantage of the pump according to the present invention is that the piping can be positioned neatly beside the pumping device in an idle position. [0008] Other advantages and features of the present invention will become apparent from the following description referring to the drawings. BRIEF DESCRIPTION OF DRAWINGS [0009] The present invention will be described through detailed illustration of the preferred embodiment referring to the drawings. [0010] FIG. 1 is a perspective view of a pump according to the preferred embodiment of the present invention. [0011] FIG. 2 is an exploded view of the pump shown in FIG. 1.
