Abstract

A blade holding device for securely holding a saw blade includes a holding unit, a sleeve member, a retaining unit, and a shell. The holding unit includes a clamp member and an insert. The clamp member has two half portions defining a gap for receiving the saw blade, a slot extending through one of the half portions, and an abutment surface. The insert is inserted into the slot, abuts against the abutment surface, and has a threaded hole. The sleeve member surrounds the half portions of the clamp member without blocking the threaded hole. The retaining unit includes a fastening member extending threadedly through the threaded hole for pressing against the saw blade. The shell surrounds the sleeve member and the clamp member.

First claim

What is claimed is:

1. A blade holding device for securely holding a saw blade, said blade holding device comprising:
a holding unit including
a clamp member that has two spaced-apart half portions defining a gap therebetween, a slot extending through one of said half portions and communicating spatially with said gap, and an abutment surface being adjacent to said slot, said gap being adapted for receiving the saw blade, and
an insert that is inserted into said slot, that abuts against said abutment surface, and that is formed with a threaded hole;

a sleeve member surrounding said half portions of said clamp member without blocking said threaded hole;
a retaining unit including a fastening member that extends threadedly through said threaded hole and that is adapted to press against the saw blade for securing the saw blade; and
a shell having a shell body that surrounds said sleeve member and said clamp member, and that is formed with a window to expose said threaded hole.

2. The blade holding device as claimed in claim 1 , wherein said retaining unit further includes a lock pin that secures said sleeve member to said clamp member.

3. The blade holding device as claimed in claim 2 , wherein:
said half portions of said clamp member extend in a longitudinal direction, and are spaced apart from each other in a transverse direction transverse to the longitudinal direction;
said gap extends in the longitudinal direction; and
said sleeve member has a surrounding wall that extends in the longitudinal direction, that surrounds said half portions of said clamp member, and that is formed with an opening registered with said window of said shell, said fastening member extending through said window and said opening, and extending threadedly through said threaded hole of said insert.

4. The blade holding device as claimed in claim 3 , wherein:
said clamp member further has a body portion connected to said half portions, and an aperture extending through said body portion;
said sleeve member further has a through hole that extends through said surrounding wall; and
said lock pin extends through said through hole and said aperture.

5. The blade holding device as claimed in claim 4 , wherein:
said sleeve member has two of said through holes that are registered with said aperture;
said lock pin extends through one of said through holes, said aperture, and the other one of said through holes, and has opposite end portions corresponding respectively in position to said through holes; and
said shell body is formed by injection molding, surrounds said sleeve member and said body portion of said clamp member, and is connected to said end portions of said lock pin.

6. The blade holding device as claimed in claim 3 , wherein said opening of said sleeve member is smaller than said insert so that said sleeve member and said clamp member cooperatively confine said insert therebetween.

7. The blade holding device as claimed in claim 1 , wherein said insert is formed with two of said threaded holes, and said retaining unit includes two of said fastening members extending threadedly and respectively through said threaded holes.

8. The blade holding device as claimed in claim 1 , wherein:
said slot of said clamp member is elliptical; and
said insert is elliptical.

9. The blade holding device as claimed in claim 1 , wherein said insert is made of metal.
