Abstract
A jigsaw with the functions of blade scrolling and blade pendulum movement comprises a housing, a motor, a reciprocating rod and a motor transmission system. The motor transmission system transfers the rotation of the motor to an up-and-down movement of the reciprocating rod to drive the blade to make an up-and-down cutting operation. The jigsaw still comprises a control device used to control the blade scrolling and the blade pendulum movement and control device comprises a blade button, a set of link rods and a pendulum axis. The rotation of the blade button drives the reciprocating rod to rotate so as to rotate the blade. The pendulum axis is a cam mechanism used to control the rang of the pendulum movement of the blade. The rotation of the pendulum axis will drive the set of link rods so as to control the blade button.
