Abstract
The invention discloses a jig saw which comprises a body, a motor, a reciprocating rod, a transmission mechanism and a support member, wherein the motor is contained in the body; the reciprocating rod reciprocates relative to the body; the transmission mechanism is used for converting the rotation movement of the motor into reciprocating movement of the reciprocating rod; and the support member supports the body to move along the workpiece surface. The jig saw also comprises multiple rolling devices which are connected to the support member and used for moving the jig saw along the workpiece surface. By changing the sliding of the jig saw support member relative to the workpiece surface into rolling, friction between the support member and the workpiece surface is reduced, the working efficiency is improved, and the use by the operator is more labor-saving.
Description
Technical field
