Embodiment 1

[0043] This embodiment provides a reciprocating saw, which can drive the saw blade to reciprocate, so that the saw blade completes the cutting of the workpiece. Such as figure 1 and figure 2 As shown, the reciprocating saw includes a housing, a driving mechanism 1, a sliding rod 2 and a guide. Wherein, the housing is the installation structure and protective structure of the entire reciprocating saw. The front end of the housing forms an accommodation space, and the driving mechanism 1 , the slide bar 2 and the guide are all located in the accommodation space. The rear end of the housing forms a grip handle so that the user can hold the reciprocating saw for operation. A battery is installed at the rear end of the housing for powering the driving mechanism 1 .

[0044] The front end of the slide bar 2 is provided with a saw blade for reciprocating cutting, and the rear end is provided with a lifting surface. The driving mechanism 1 is arranged on the upper part of the acco...

Embodiment 2

[0059] This embodiment provides a reciprocating saw, the structure of which is basically the same as that of the reciprocating saw in Embodiment 1, the only difference is that, as Figure 6 As shown, in this embodiment, the guide member is the chute member 7, and the chute member 7 is provided with a chute, and the chute bottom surface of the chute is plane and parallel to the direction of the first plane. One end of the sliding bar 2 that is provided with the lifting surface is placed in the chute of the chute part 7, and there is a certain distance between the bottom end of the sliding bar 2 and the bottom surface of the chute. When the sliding bar 2 reciprocates, and its end abuts on the bottom of the chute. In this embodiment, the knife-lifting surface is a second slope, and along the direction of the first plane, the height of the second slope gradually decreases.

[0060] When the slide bar 2 drives the saw blade to retract along the negative direction of the x-axis, th...

Abstract

The invention discloses a reciprocating saw, and belongs to the technical field of electric tools. The reciprocating saw comprises a driving mechanism, a sliding rod and a guide part, wherein the driving mechanism comprises a transmission part; the transmission part comprises a first transmission wheel capable of rotating around a rotating axis; the sliding rod is driven by the driving mechanism to reciprocate; a cutter lifting face is arranged at the tail end of the sliding rod; the front end of the sliding rod is connected with a saw blade; and the cutter lifting face is matched with the guide part, so that the saw blade is lifted or lowered in the reciprocating motion of the sliding rod. According to the reciprocating saw, chippings in a cutting groove can be cleaned by lifting the saw blade, and the mechanism for lifting the saw blade is simple in structure, small in occupied space and particularly suitable for small-power reciprocating saws.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a reciprocating saw. Background technique [0002] A reciprocating saw is an electric cutting tool that can drive a saw blade to reciprocate to cut a workpiece. The saw blade of the reciprocating saw needs to lift the knife upward during the return stroke to clean up the debris in the cutting groove on the workpiece. The mechanism for lifting the saw blade in the existing reciprocating saw is not only complicated in structure, but also takes up a lot of space. The knife-like structure seriously affects the cutting efficiency. [0003] Therefore, how to propose a knife-lifting mechanism with simple structure, less space occupation, and better knife-lifting effect, and the knife-lifting mechanism can be applied to reciprocating saws with high power and low power at the same time is a technical problem that needs to be solved urgently . Contents of the invention [0004...
