Pocket hole jig

1. A pocket hole jig comprising:

a body, a holder, and a fitting sleeve, wherein:

the body includes at least one accommodation orifice defined on one end thereof and configured to house a driller, each accommodation orifice tilting downwardly and extending toward a bottom of the body, the body also including a first marking portion arranged on a first side surface thereof;

the holder includes an operation room in which the body is fitted and moves relative to the holder, at least one through groove formed on a bottom of the holder so as to correspond to the at least one accommodation orifice, and a first scale section arranged on a first side surface thereof and aligning with the first marking portion, such that a user can distinguish a position of the body relative to the holder and can also determine a size of a screw; and

the fitting sleeve is configured to fit onto the driller, the holder further including a depth scale section for measuring depths of holes to be drilled on wooden workpieces by the driller;

the holder further includes a stop plate and a dovetail block, the dovetail block arranged on a first end of the holder, the stop plate having a dovetail trench for engaging with the dovetail block and has a contacting extension fixed over a top or the bottom of the holder;

the body further includes a second marking portion arranged on a second side surface thereof, and the holder further includes a second scale section arranged on a second side surface thereof and aligning with the second marking portion, such that the user can distinguish the position of the body relative to the holder and can also determine the size of the screw; and

when the contacting extension is fixed over the top of the holder, a position of the body relative to the holder is adjustable by way of the first marking portion and the first scale section, and when the contacting extension is fixed over the bottom of the holder, the body and the holder are usable to measure drilling positions of the wooden workpieces by way of the second marking portion and the second scale section.

2. The pocket hole jig as claimed in claim 1 , wherein the contacting extension has a receiving trough defined thereon so as to house the driller.

3. The pocket hole jig as claimed in claim 1 , wherein the holder further includes at least one rib formed in the operation room, and the body further includes a toothed section arranged on the bottom thereof so as to selectively engage with the at least one rib.

4. The pocket hole jig as claimed in claim 1 , wherein the body includes a first magnetic attraction element mounted on the bottom thereof, and the holder includes a metal projection for magnetically attracting with the first magnetic attraction element.

5. The pocket hole jig as claimed in claim 1 , wherein the body further includes at least one chip elimination opening defined on the top thereof and communicating with the two accommodation orifices.

6. The pocket hole jig as claimed in claim 1 , wherein the body further includes a pressing face formed on the top thereof, and the pressing face has anti-slip patterns arranged thereon.

7. The pocket hole jig as claimed in claim 6 , wherein the body further includes a second magnetic attraction element secured on the pressing face thereof.

8. The pocket hole jig as claimed in claim 6 , wherein the holder further includes a thickness scale section arranged on the bottom thereof so as to measure thicknesses of the wooden workpieces.
