Embodiment Construction

[0038] refer to Figures 1 to 7 , shows a wire saw machine (or jigsaw) according to a preferred embodiment.

[0039] The jigsaw machine includes a housing 100 for housing or mounting the functional components of the saw.

[0040] The housing 100 has a motor receiving portion 100a (which is preferably figure 1 The handle portion of the saw is formed as shown), wherein the motor 1 for providing driving force to the saw blade 20 is fixedly installed therein. Alternatively, the motor receiving portion 100 a is only used to accommodate the motor 1 , and a separate handle (not shown) is attached to or integrally formed with the housing 100 .

[0041] The electric motor 1 can be fixed in the housing 100 by means of screws, retaining ribs or form locks. The motor 1 is powered by a rechargeable battery or an external power source.

[0042] The housing 100 may be formed by standard means, such as is commonly used in DC appliances, for example by plastic moulding.

Abstract

A jigsaw comprises a housing (100), a motor (1) fixed in the housing (100) and a driven shaft (6) rotatably mounted in the housing (100). A transmission mechanism is used to transmit the output rotation of the motor (1) to the driven shaft (1). Two eccentric type outputs are obtained from the driven shaft (6) for driving the saw blade to reciprocate and oscillate simultaneously. The jigsaw is compact and light weighted and is easy to manufacture and use.

Description

technical field [0001] The present invention relates to a wire saw or jigsaw. Background technique [0002] A jigsaw (or jigsaw) or any other hand saw with an eccentrically driven saw blade is known. Such a wire saw machine has a saw blade that is driven in two directions simultaneously, namely in the reciprocating direction and in an oscillating direction lateral to the reciprocating direction. In the reciprocating direction, the saw blade is driven to reciprocate to cut the workpiece. In the oscillating direction, the saw blade is driven to oscillate forward, thereby urging the saw blade forward in the workpiece. [0003] In order to realize the drive action in both directions, two drive mechanisms are usually arranged in the housing of the wire saw machine. Thus, known wire saw machines are generally bulky and heavy, and thus difficult to manufacture and use. Contents of the invention [0004] In view of the problems existing in the prior art, the object of the pres...
