Field of the Invention This invention relates to a nailing assembly, and more particularly to a magazine for adjusting the width of a staple groove for receiving a staple row. [Prior Art] In view of the fact that the nails used for nailing are fixed widths, when the outer diameters of the nail rows are different, or the sizes of the plastic materials connected between the nails are different, a gap is formed between the nail rows and the nailing grooves, so that the nails are The row is easy to sway or overlap, and the nailing operation is less smooth. Therefore, the applicant applied for the new type M249777 "adjustable track width of the nail slot", as shown in the figure, the patent The case has a shackle U, a baffle 12, a bolt 13 and an elastic 70 丨4. The sley 11 has a nail groove ηι for accommodating a nail row 2, a first hole 112 and a second hole 形成 formed on one side, and the first and second holes are connected. 12. A necking hole 1M of n3 and two positioning holes 115. The baffle 12 is disposed in the nailing groove ln, and has a pushing surface 121 formed on one side and pressing against the nail row 2, and two protruding side faces and respectively abutting the sley 11 The lock block 122 and the second block 123 ^ the bolt 13 passes through the sill u and is fixed with the baffle 12, and has a plug 13 formed at one end, and adjacent to the other end and can enter the The first hole 112 or a convex ring 132 of the second hole. The resilient member 14 is abutted against the peg 131 of the bolt 13 and the cymbal cymbal. When the width of the nailing groove 111 is adjusted, the bolt 131 of the bolt 13 is first pressed, and the convex ring 132 is disengaged from the first hole 112 or the second hole 3 to push the baffle 12 to be generated. Moving, when the baffle 12 is forced against the seat u by the 1345517 lock block 122, the brace member is forced to compress the elastic member 14 by the sling u, so that the pushing surface i2i is closer to the The pinning plate 111' is further adapted to mount a smaller size of the nail row 2, and when the baffle u is inserted into the positioning holes 115 by the locking blocks 122, the playing board 12 is subjected to the bombing! The elastic force of the το member 14 is pulled to the squeegee π with the stoppers (2), so that the pushing surface 121 is farther away from the nailing groove (1) and is adapted to install a larger size of the rotation 2, thereby achieving By adjusting the width of the nailing groove ιη, it is possible to push the nail row 2' of different sizes by the pushing surface i2i to generate a function for improving the smoothness of the nail. ...however, although the patent case has the above-mentioned functions, the practical existence of =12 is the metal strip body, resulting in a heavier overall weight, more laborious use, higher manufacturing cost, and the baffle needs to be driven during adjustment. Η The area where the operating force is to be improved. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an adjustable staple groove that can be nailed at a low manufacturing cost and that is less labor intensive.
