Palm jig saw

摘要

A palm jig saw includes a motor, a transmission mechanism connected to an output shaft of the motor, and an implementing element which is driven by the transmission mechanism and which movement trajectory is in the same plane called a swing plane. The palm jig saw further includes a switch locking structure including a push button assembly and a press button assembly, wherein a movement direction of the push button assembly is generally parallel to the swing plane, and a movement direction of the press button assembly is generally perpendicular to the swing plane.

1. A palm jig saw, comprising:
a housing adapted for palm gripping comprising a first side wall and a second side wall opposite to the first side wall, the first and second side walls respectively define a first recess and a second recess for gripping; a base connected to the housing for contacting with a workpiece and supporting the palm jig saw; a motor having an output shaft arranged within the housing, the output shaft being generally parallel to the base; a transmission mechanism connected to the output shaft of the motor which comprises a slide bar, the slide bar being capable of moving in a direction generally perpendicular to the output of the motor; an implementing element connected to the slide bar, which is driven by the transmission mechanism to move in a swing plane; a battery pack for powering the motor inserted into the housing, an inserting direction of the battery pack being generally parallel to the output shaft of the motor, the battery pack being positioned between the motor and the base and partially overlapped with the motor in a direction generally perpendicular to the base; and a switch locking structure comprising a push button assembly and a press button assembly, the push button assembly and the press button assembly being positioned adjacent to the first and second recess respectively, the push button assembly being capable of moving in a first direction which is generally parallel to the swing plane, the press button assembly being capable of moving in a second direction which is generally perpendicular to the swing plane, and wherein the switch locking structure further comprises a first resilient element mounted on the push button assembly and a second resilient element mounted on the press button assembly, the first resilient element being positioned generally perpendicular to the second resilient element, the push button assembly and the press button assembly being capable of moving reciprocatingly under the action of the first resilient element and the second resilient element respectively, the push button assembly being formed with a locking protrusion, and the press button assembly being formed with a drive arm for triggering a switch of the palm power tool and a locking slot for embedding the locking protrusion.
