PROBLEM TO BE SOLVED: To provide a tabletop extrusion device that is effective and has high convenience according to the appearance of a packaging bag 10.SOLUTION: A predetermined ratchet mechanism is constituted by: a roller 3 provided as a turnable fixed weir fixed in the predetermined position of right and left upright plate parts A for extruding a flexible material 10' stored in a packaging bag 10 on the surface of a flat plate 6 smoothly moving to the left direction in a guide rail unit constituted between the upright plate parts A; right and left claw teeth parts 8 constituted having a shape for smoothly moving the flat plate to the right direction where the flexible material 10' on the flat plate 6 is extruded in the length direction at the right and left end parts of the lower part of the flat plate 6 and to the opposite left direction, for facilitating the flat plate 6 to perform the predetermined smooth movement, while preventing the extrusion operation through the roller 3 from impairing extrusion functions in the guide rail unit; and a claw gear 9 engaged with the right and left claw teeth parts 8. A handle 2 for rotating the claw gear 9 is provided at the upright plate part of one side. |
