Embodiment Construction

[0068] Figure 1-8 The structure of a band saw 10 implementing some aspects of the present invention is shown. The band saw 10 generally includes a housing or frame 14 that supports a motor 18. The motor 18 is connected to the drive assembly 22 in a drivable manner, and the motor 18 and the drive assembly 22 can operate to drive a continuous band saw blade 26 to cut the workpiece W. As described above, the band saw 10 includes a front part 27 and a rear part 28. The front part 27 is defined as the side close to the part of the band saw blade 26 that cuts the workpiece W, and the rear part 28 is defined as the side close to the part of the band saw blade that does not cut the workpiece W. Or the rear part 28 is described as facing the front part 27.

[0069] The housing 14 includes a main handle 30 that supports the on / off switch assembly 34. The switch assembly 34 is operable to control the operation of the motor 18. The band saw 10 also includes an auxiliary handle 38 for the op...

Abstract

A power tool, such as a band saw, is provided and may include a housing having a first handle and a second handle, a motor, a first wheel, a second wheel and a battery supported by the housing and electrically connectable to the motor for powering the motor, the battery is at least partially positioned at least one of between the first handle and the second handle and between a first wheel axis of the first wheel and a second wheel axis of the second wheel. In some aspects, a power tool may include a battery support for supporting a battery, the battery support being formed separately from a housing of the band saw and being supportable by the housing. In other aspects, a band saw may be operable with at least a 26 Volt battery.

Description

[0001] Instructions for Divisional Application [0002] This application is a divisional application of a Chinese invention patent application whose application number is 200510052570.6, the name of the invention is "band saw", and the application date is February 21, 2005. [0003] Related application [0004] The present invention claims to protect the rights and interests of the previously filed jointly pending US provisional patent application No. 60 / 546,489 filed on February 20, 2004 and No. 60 / 623,422 filed on October 28, 2004, the entire contents of which are combined Take it here as a reference. Technical field [0005] The present invention relates to electric tools, in particular to band saws. Background technique [0006] The existing portable band saws have various technical problems and shortcomings. One of the problems includes unbalanced band saws, which have most of their weight near the front, rear, left, or right side of the band saw, so that most of the weight i...
