Saw blade clamping device

A saw blade clamping device for a linearly reciprocating type sawing machine being configured to clamp at least two types of saw blades, comprising:

• a clamping seat having a connecting portion configured to be driven by the linearly reciprocating type sawing machine and a loading portion formed by extending from the connecting portion, the loading portion having an outwardly facing surface and a loading slot;
• an operating member comprising an operating portion with an assembling end and a loading end formed on opposite ends of the operating portion respectively, the operating portion being assembled around the loading portion of the clamping seat with assistance from the assembling end, the loading end being configured with a loading port;
• and
• an abutting element disposed between the operating member and the clamping seat, the abutting element configured to contact the outwardly facing surface of the loading portion, the abutting element having an abutting end,
• wherein the operating member is configured to be rotated with respect to the loading portion, an inner wall of the operating member is configured with a driving surface formed in the form of a curved surface, the abutting element is configured with a driving end that abuts against the driving surface, and the abutting end of the abutting element is configured to be driven by the driving surface during the rotation of the operating member to move in a direction toward an inserted saw blade to abut against and fix the inserted saw blade,
• wherein the abutting element comprises a U-shaped member having a protrusion configured on a U-shaped portion and two branched arms extending from the U-shaped portion, the protrusion acting as the driving end of the abutting element, and tip ends of the branched arms acting as the abutting end of the abutting element
• wherein the loading portion is in the form of a cylinder and comprises a first clamping piece and a second clamping piece, the loading slot extending in the longitudinal direction of the loading portion between the first clamping piece and the second clamping piece,
• wherein a notch is configured on each of opposite sides of the first clamping piece, and the notches communicate with the loading slot, and
• wherein the two branched arms of the U-shaped member are received in the two notches of the first clamping piece respectively.
