A female screw portion 24 is formed over the entire length of a through hole 23 passing through an axis of an ultrasonic horn 13, first and second male screw portions 25, 26 formed on the ultrasonic horn 13 side of axes of first and second boosters 14, 15 are screwed into the female screw portion 24, the ultrasonic horn 13 and the first and second boosters 14, 15 are fastened coaxially, leading ends 27, 28 of the first and second male screw portions 25, 26 are not in contact with each other inside the through hole 23, and a cutting blade 12 is attached to an outer periphery of a base portion 20 of the ultrasonic horn 13 having a space portion 29 surrounded by an inner wall of the through hole 23 and the leading ends 27, 28 of the first and second male screw portions 25, 26.

The present disclosure provides a reversible cutting tool to cut a material such as sheet metal on a press brake. The reversible cutting tool is further comprised of a handle portion to grip and move the cutting tool, wheels to allow the cutting tool to slide along the press brake, a blade portion to cut the material, and an adjustable cutting mechanism. The adjustable cutting mechanism allows the reversible cutting tool to pivot and cut the material in two different directions, and also allows the cutting tool to be set in a third storage position. In a preferred embodiment, the adjustable cutting mechanism is comprised of a channel on an underside of the cutting portion, the channel configured to receive a plunger, the plunger to slide between two opposed cutting positions and a storage position.

A movable dust collection device includes a processing table, a processing machine, and a collection unit. By the movable suction box, the dust, small parts and debris under the processing gun can be directly sucked and collected. The control unit controls the motor to drive the driving wheels to move the suction box beyond the processing table, which facilitates the cleaning of the small parts and debris, and improves the shortcoming of lifting the entire collection board for cleaning in the prior art.
