PURPOSE:To correctly further stably drive a nail, by both longitudinally driving a nail driving head and providing a clamping cylinder which advances to the front from the nail driving head retaining a material for a nail to be driven. CONSTITUTION:A device, extending a main longitudinal cylinder 15 and the second longitudinal cylinder 18, advances a longitudinally moving bed 13 and a clamping cylinder mounting frame 16. If they advance reaching their advancing end, the device, lowering a clamping cylinder 17 to press an edge material 3 and a panel frame 2 to a work bed 1 and actuating a nail driving head 14, drives a nail in a bottom row of the edge material 3. The device, if it completes its driving, lifts the clamping cylinder 17 and retreats the main longitudinal cylinder 15 and the second longitudinal cylinder 18. The device, lifting a lift cylinder 12 in the retractive end, again in the lifting end advances the main longitudinal cylinder 15 and the second longitudinal cylinder 18. In the advancing end, the device, lowering the clamping cylinder 17 to again press the panel frame 2 and the edge material 3, drives a nail in an upper row of the edge material 3 by the nail driving head 14. |
