Abstract

The invention discloses a following cutter device of a jig saw. The following cutter device comprises a bottom plate fixed to the bottom of the jig saw, and is characterized in that a working cavity is upwardly formed at the bottom of the bottom plate, a following cutter can be arranged in the working cavity in a concealed manner by means of rotating inwardly, and a part of the following cutter is exposed out of the bottom of the bottom plate when the following cutter in an outward rotation state. The following cutter device has the advantages that the following cutter device is simple and practical in structure and convenient to use; the jig saw can be used as the traditional jig saw when the following cutter is folded, and can be used for sawing straight lines when the following cutter is unfolded, and the straight lines are quite straight; the following cutter device is convenient to operate, a following cutter board can be quickly folded when the jig saw is used for sawing curves, and the like.

Description

technical field [0001] The invention relates to a follower device of a curve saw, which belongs to the field of electric tools. Background technique [0002] Because it is mainly for sawing curves, existing curve saws basically do not have a follower knife device, so it is difficult to straighten when required to saw a straight line. [0003] Although there is a follower device on some sawing devices such as table saws, a Chinese patent with a patent application number of 200910165598.9 reports a table saw, and the table saw includes a workbench, a base, a circular saw blade, and a follower The knife plate is operable to rise or fall together with the circular saw blade; the guard is movably connected to the heel knife plate, and the guard is located above the circular saw blade, wherein the heel knife plate A stopper mechanism is provided, and a mating device is provided on the shield, and the mating device can be selectively mated with the stopper mechanism, thereby restr...
