CLAIM OF PRIORITY [0001] This application is a continuation application of U.S. patent application Ser. No. 10/760,128 filed Jan. 16, 2004 and claims priority under 35 U.S.C. .sctn.119 to Chinese Patent Application No. 03219560.5 filed Jan. 24, 2003, which are hereby incorporated herein by reference in there entirety. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a handheld power tool such as a buffer or a polisher. [0004] 2. DESCRIPTION OF THE RELATED ART [0005] Conventional handheld power tools for buffing or polishing comprise a main housing, a rear handle mounted on the main housing and a handle connected to the main housing. The handle adopts a substantially circular configuration. A base portion of the main housing has a buffing member in the basal plane. The handle and the basal plane of the buffing member are parallel. During the buffing of a workpiece, the operator's wrists bend to a large degree to accommodate the parallel disposition of the buffing member and the handle. This rapidly causes the operator's wrists to tire and the buffing effect to be inefficient. FIGS. 4 and 6 are intended to illustrate the bend which must be deployed in the operators wrists to operate the buffing member at the base of the main housing 2. SUMMARY OF THE INVENTION [0006] It is an object of the present invention to provide an easily operated handheld power tool such as a buffer or a polisher. [0007] Thus viewed from one aspect the present invention provides a handheld power tool including: [0008] a main housing having a base portion, wherein the base portion has a buffing member in the basal plane, [0009] a rear handle mounted on the main housing, [0010] a handle connected to the main housing, wherein the handle comprises: [0011] two oppositely disposed side handle members each having a front end portion and a rear end portion and [0012] a front handle member connected between the front end portions of the two oppositely disposed side handle members, wherein the front handle member has side end portions, [0013] wherein the two oppositely disposed side handle members are tilted with respect to the basal plane. [0014] The present invention relates to a handheld power tool including: a main housing, a rear handle mounted on the main housing and a handle connected to the main housing. A base portion of the main housing has a buffing member in the basal plane. The handle comprises two oppositely disposed side handle members and a front handle joined between the front end portions of the two oppositely disposed side handle members. The two oppositely disposed side handle members tilt (ie are non-parallel) with respect to the basal plane. [0015] The present invention has the advantage that during buffing of a workpiece, the operator's wrists need bend to only a small degree to accommodate the non-parallel disposition of the buffing member and the handle. The pressure applied to the operator's arm is substantially in the same direction as that applied by the main housing to the workpiece leading to labour efficiency and reduced wrist tiredness. [0016] Preferably the two oppositely disposed side handle members each have at least one upwardly arched arcuate portion. [0017] Preferably the front handle member has an upwardly arched arcuate portion. [0018] In a preferred embodiment the handle further comprises: [0019] a rear connecting member joining the rear end portions of the two oppositely disposed side handle members and having side end portions, wherein the rear connecting member is cooperatively connected to the rear handle. [0020] Preferably the front end portions of the two oppositely disposed side handle members are smoothly interconnected respectively with the side end portions of the front handle member and the rear end portion of the two oppositely disposed side handles are smoothly interconnected respectively with the side end portions of the rear connecting member. [0021] In a preferred embodiment, the handle further comprises: Continue reading about Handheld power tool...
