[0021] The horizontal pushing device is in contact with the side surface of the nail magazine 4 and is not connected with the nail magazine 4, and the horizontal pushing device is used to push the nail magazine 4 to move horizontally, and the horizontal moving direction is perpendicular to the moving direction of the nail pushing device.

[0022] After the horizontal pushing device is pushed to the position, the pushing force is immediately released, and the positioning mode is kept until the nails are finished, and the cycle is repeated,

[0023] The depth of the nail groove of the nail magazine 4 is 1 / 2-2 / 3 of the length of each nail, and the exposed part of the nail row is close to the plane of the guide wall 31 of the side edge of the mounting seat 3 as the positioning surface of the nail row fed into the nail inlet 12.

[0024] The nail magazine 4 is movably arranged in the mounting seat 3 in a manner that the nail magazine 4 can be freely taken out and put in (for example, directly placed), so that the nail magazine 4 can be freely taken out to fill the nail row 10. A guide wall 31 is arranged on the side edge of the mounting seat 3, and the guide wall 31 is parallel to the direction of the nail row 10 and adjacent to the outermost nail row of the nail magazine 4, and the outermost nail row is aligned with the nail inlet 12.

[0025] The nail pushing device comprises a pushing strip 6 and a pushing component, the pushing strip 6 is movably arranged on the guide wall 31 and opposite to the nail inlet 12, and the pushing component is connected with the pushing strip 6.

[0026] The inner side wall of the guide wall 31 is provided with a sliding rail 32, and the outer wall of the pushing strip 6 is provided with a guide rail 62 matched with the sliding rail 32, and the guide rail 62 is arranged in the sliding rail 32 to form a sliding matching structure between the pushing strip 6 and the guide wall 31.

[0027] The pushing component adopts a pushing nail cylinder 8 (an electric cylinder, an oil cylinder, a motor or a spring can also be used as a power mechanism), the pushing strip 6 is provided with a pushed arm 61 connected with the pushing nail cylinder 8; the pushing nail cylinder 8 is installed on a fixed seat 7, and the fixed seat 7 is installed at the tail of the mounting seat 3; the lower side of the pushed arm 61 is adjacent to the upper side of the nail row, and the front end of the pushed arm 61 is provided with a guide inclined surface, which can smoothly press the rear 4 rows of nails when the pushing strip 6 is pushed forward, and arrange the rear nail rows in the pushing state, so that the rear nails can smoothly and accurately reach the chute.
