To reduce efficiently joints of a continuous bamboo material by fixing a stopper on one end of a horizontal direction guide rail of specified length and providing a movable blade with a blade rotating shaft structure movable along the guide rail on the opposite side of the stopper of the guide rail.

An end press plate 2 for fixing a material to be processed is provided on a guide rail 1 of at least 9 m length, and an elastic body 3 is stuck on an inner face of a holding frame 4, and when a handle 5 is rotated in the hand direction of a clock, the holding frame 4 is closed, while when the handle is rotated in the counterclockwise hand direction, the holding frame is closed. A fixing plate 6 of the rotating shaft of a plate for cutting and removing bamboo joints is fixed on the guide rail 1, and movable plates 7 and 9 sliding on the guide rail 1 while supporting the rotating shaft are provided. An easily recognizable red mask is formed on the position of the plate on the end of the rotating shaft 8 on a chain belt driving the movable plate 9 so that the location of the blade moved onto the bamboo material during the work of removing the joints can be recognized.
