The dust suction head 4 has a connection structure connected with the head of the dust collector for use by being mounted on the head of the dust collector. The dust suction head 4 is substantially a square, and a circular through hole 41 is formed at the center of the dust suction head, and the through hole 41 is used for communicating with a dust suction pipeline of the dust suction machine, so that negative pressure generated by the dust suction machine can be used for sucking the dust through the through hole 41. The four corners of the dust suction head 4 are respectively provided with a through hole 43, and the through holes 43 are used for screws to pass through, so that the dust suction head 4 can be fixedly connected with the head of the dust collector through screw holes passing through the through holes 43. A groove 42 is formed in one end face of the scrap suction head 4, an opening at one end of the through hole 41 is formed in the center of the bottom of the groove 42, a notch is formed in one side face of the scrap suction head 4 of the groove 42, and a cutter head of a blade of the scissors 2 extends into the groove 42 from the notch. The groove 42 has a sufficient groove width so that the scissors 2 are not affected by the groove wall of the groove 42 during the left-hand cutting action. The recess 42 has a sufficient depth so that the cutting head of the blade of the scissors 2 projecting therein can be completely received therein. The through hole 43 is partly located at the groove bottom of the groove 42 and partly located at the groove wall of the groove 42, so that the blade head of the blade of the scissors 2 is provided with a clearance groove 21 for avoiding the through hole 43 at the blade back in order to avoid the through hole 43.

The pin shafts of the scissors 2 are positioned in the gap and are connected to the two mounting plates 3 in a positioning way.
