Embodiment Construction

[0049] see Figure 1 to Figure 3, the first embodiment of the present invention is disclosed. A jigsaw 100, comprising: a vertically downward saw blade 1 for cutting workpieces; a motor 2 with a rotation axis X for driving the saw blade 1, and the motor 2 is connected to a power supply through a cable 16; a transmission device 3, used to transmit energy from the motor 2 to the saw blade 1; the first housing 4, used to accommodate the motor 2; the second housing 5, used to accommodate the transmission device 3; the handle 6; the connecting device 7; the bottom plate 11, For supporting the jig saw on the workpiece and the brackets 12 , 18 . It should be noted that the motor 2 here is not limited to an electric motor, and an air motor can also be used.

[0050] The handle 6 is rotatably connected to the first housing 4 through the connecting device 7, and the handle 6 rotates around the rotation axis X or the axis Y substantially parallel to the axis X. The bottom plate 11 sup...

Abstract

The invention discloses a sweep saw with a rotary handle. The sweep saw with the rotary handle comprises a saw blade for machining workpieces, a motor for driving a saw blade, a transmitting mechanism and a handle, wherein the motor is contained in a first shell; the conveying mechanism is used for transmitting energy to the saw blade from the motor, and is contained in second shell; the handle is used for moving the sweep saw, and enables the sweep saw to move relative to the workpieces; and the handle is supported on the first shell or the second shell, and rotates relative to one of the first shell or the second shell. The sweep saw is small in volume, and can guarantee certain machining precision in obliquely sawing.

Description

[0001] This application is a divisional application of the Chinese invention patent application filed by the applicant on June 18, 2007. The title of the invention is "curve saw" and the application number is 200710126769.8. technical field [0002] The present invention relates to a jigsaw, in particular to a jigsaw with a rotary handle. Background technique [0003] In the existing jigsaw, the handle is usually fixed on the fuselage. When in use (such as a miter saw), the handle will slant to one side along with the body, and the operator will hold the slanted handle to operate. In this way, the operator must exert force on the handle, so that the handle continues to deflect downward, so as to avoid the change of the angle of the saw blade and affect the operation accuracy. [0004] In order to solve this problem, Japanese published patent application JP7-171802 discloses a jigsaw, which includes a body and a base. The jigsaw can obliquely cut workpieces. When obliquely ...
