Abstract
A miter saw has a base and a rotatable table mounted on the base. A support is mounted on the rear of the table. A pivot arm is pivotally connected to the support through a connecting shaft. A cutting assembly is connected to the pivot arm. A locking member is connected between the support and the pivot arm. An electromagnetic member is connected to the locking member through a linking device. The electromagnetic member is electrically connected to a switch which is used to control a supply of actuating power to the electromagnetic member.

A miter saw, comprising:
- a base;
- a table rotatably mounted on the base and having a supporting surface;
- a support mounted on a rear of the table;
- a pivot arm pivotably connected to the support through a connecting shaft;
- a cutting assembly connected to the pivot arm having a blade wherein a central axis of the connecting shaft lies approximately on a supporting surface of the table and is approximately perpendicular to a rotation axis of the blade;
- a locking member connected between the support and the pivot arm for locking the pivot arm in a position relative to the support;
- an electric member for causing operation of the locking member through a linkage;
- and
- a switch electrically connected to the electric member for controlling an actuating supply of power to the electric member.
