Embodiment Construction

[0031] Such as figure 1 and figure 2 As shown, the jigsaw 1 of the present invention includes a front body 7, a main body 2, a motor 6 located in the main body 2, a first switch 103, a saw blade 3 for cutting, and a saw blade 3 located in the front body. A mechanical transmission device 71 (not shown) for converting the rotary motion of the motor 6 into the reciprocating motion of the saw blade 3, a detachable handle 10, laser marking device 4, lighting device 5, saw blade clamping device 30, and base plate 20.

[0032] First, the attachment and detachment of the handle will be described. As shown in Figure 4, the front end of the handle 10 has an insert 14 for positioning the position of the handle. There is a hole 140 on the front body 7 to match the insert 14. Insert the insert 14 into the hole 140, and the two can be closely matched. Thereby the position of one end of the handle 10 on the front body 7 is determined. A pair of connecting devices 18 are arranged at the ...

Abstract

The invention discloses a cock saw which comprises a main body, an electric motor inside main body, a switch triggering bar on the main body and a handle, wherein the handle is an independent device which can be detached by operator and contains a handle switch triggering bar; when the said handle is fixed on the main body, the switch triggering bar of main body is on the scram position so that it must use handle switch triggering bar to open or close the cock saw.

Description

technical field [0001] The present invention relates to an improved power tool, especially a jigsaw. It has multiple functional features, is easy to operate, and can better realize the cutting function. Background technique [0002] The jigsaws that can be seen on the market have two kinds of holding modes at present, and one is that the operator directly grasps the fuselage to operate, and the other is that there is another handle on the jigsaw fuselage for the operator to hold. A jigsaw usually includes a cutting part (mainly including a saw blade and a reciprocating rod) perpendicular to the cutting surface, and a motor part parallel to the cutting surface. The operator can hold the shell of the motor part to achieve stable and precise operation. However, the motor part is relatively thick. Once the operation time is too long, coupled with factors such as motor heating and machine vibration, the operator will feel very tired, which will reduce work efficiency and even A...
