CROSS REFERENCE [0001] The present application is a continuation-in-part application of U.S. patent application Ser. No. 11/306,012, filed on Dec. 14 2005, of which the entire disclosure is incorporated herein. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a pumping device. [0004] 2. Description of the Related Art [0005] Taiwan Application No. 86214553 discloses a pumping device comprising a head 32, a barrel 40, and a handle 50. To operate the pumping device, the handle 50 is pivoted to a position such that the handle 50 and the barrel 40 are in a perpendicular relationship. To store the pumping device, the handle 50 is pivoted to a position such that the handle 50 and the barrel 40 are in a parallel relationship. One problem that the pumping device suffers is that the pumping device has no means for securely retaining a rod 32 within the barrel 40 when not in use. Another problem is that the head 32, the barrel 40, and the handle 50 have different external diameters. Thus, the pumping device is not aesthetically pleasing. Yet another problem is that the handle 50 is generally made of plastic material and has a resilient open end 52. However, the resilient open end 52 can be deformed by the user during pumping operation, and leading to an insufficient pumping action. [0006] Taiwan Application No. 86221565 discloses another pumping device comprising a body 10, and a handle 17, in which the handle 17 securely fixed to the body 10 when not in use. The pumping device further includes a pressing portion 161 by which the handle 17 can be disengaged from the body 10 when being pressed. One problem that the pumping device suffers is that it is likely that the pressing portion 161 is accidentally pressed. Another problem is that the handle of the pumping devices can be deformed during pumping operation, as the handle 17 is made of plastic material. [0007] Taiwan Application No. 91219135 discloses another pumping device comprising a barrel 1 and a rod 13. One problem that the pumping device suffers is that the rod 13 can not be securely retained within the barrel 1 when not in use. Another problem is that the pumping device has a handle 2 configured too long to make the pumping operation sufficiently. [0008] The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art. SUMMARY OF THE INVENTION [0009] Accordingly, the present invention overcomes the disadvantages of the prior arts by providing a pumping device having a consistent external diameter and good securement of parts when not in use. [0010] It is also an objective of the present invention to provide a pumping device that is not easily deteriorated by sun and rain. [0011] It is another objective of the present invention to provide a pumping device that is light-weighted. [0012] It is yet another objective of the present invention to provide a pumping device that has a first tube and a second tube for accommodating the first tube, and with the second tube being made from alloy or carbon composite. [0013] It is still another objective of the present invention to provide a pumping device that has a first handle portion and a second handle portion for accommodating the first handle portion, and with the second handle portion being made from alloy or carbon composite. [0014] A pumping device comprises barrel including a first tube having a first end and a second end and a second tube which surrounds the first tube. A head for connecting to a valve attached to the first end of the first tube. A pumping means includes a rod having an end attached to a disc, and an opposite end attached to a connecting member. The disc is moveable in the first tube. The connecting member is adapted to be latched to the first tube. A handle pivotally connected to the connecting member includes a first handle portion and a second handle portion which surrounds the first handle portion, whereby the handle can be pivoted to a position for receiving the connecting member, with the second handle portion including a portion wrapping the second end of the first tube, and whereby the handle can be pivoted to another position for ease and efficacy of pumping operation. [0015] Other objectives, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0016] FIG. 1 is a perspective view of a pumping device in accordance with the present invention.
