Abstract

The router of the present invention includes a motor housing for enclosing a motor, a support foot for receiving the motor housing, and an adjustment rod mounted to the support foot. The adjustment rod includes a first engagement part and the motor housing includes a second engagement part matched with the first engagement part. The adjustment rod can move between a first position where the first engagement part engages the second engagement part, and a second position where the first engagement part disengages from the second engagement part. As a result, both a fine and a coarse cutting depth adjustment are performed conveniently and easily.

Claims

1. A router, comprising:

a motor housing for enclosing a motor;

a support foot for receiving said motor housing;

an adjustment rod pivotally mounted to said support foot at one end thereof;

wherein an adjustment button is mounted to said adjustment rod, and part of said adjustment button extends out of said support foot;

said adjustment rod including a first engagement part;

said motor housing including a second engagement part matched with said first engagement part; and

,

a switching button that includes a cam surface is mounted to at least one of the adjustment rod and the support foot.

2. A router as claimed in claim 1, wherein said adjustment rod is able to move between a first position where said first engagement part engages with said second engagement part, and a second position where said first engagement part disengages from said second engagement part.

3. A router as claimed in claim 1, wherein a part of the switching button extends out of the support foot.

4. A router as claimed in claim 1, wherein the switching button is a screw.

5. A router as claimed in claim 1, wherein a sphere is formed in one end of the adjustment rod, and a hole receiving the sphere is formed in the support foot.
