• 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 being configured with 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 having an abutting end configured to extend into the loading slot,
• 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 of extending into the loading slot to abut against and fix an inserted saw blade.
