The using method of the invention is as follows:
before the double-row straight nail gun is needed, firstly, two rows of nails 49 are respectively arranged in the left nail guiding cavity 13 and the right nail guiding cavity 14, when the nails are arranged, a worker can hold the bottom plate 20 to enable the bottom plate 20 to swing by taking the shaft pin 21 as the center, when the bottom plate 20 swings, the positioning head 34 at the rear end of the bottom plate 20 swings upwards by taking the shaft pin 21 and is separated from the positioning groove 33 of the positioning block 32, simultaneously hold the positioning handle 30 to swing by taking the self hinge point as the center, enable the positioning block 32 to swing towards the front side and enable the positioning hook 31 to swing towards the rear side, when the positioning hook 31 swings backwards, the positioning hook 31 is separated from the positioning gap 35 on the partition plate 12, the positioning hook 31 of the positioning handle 30 does not limit the movement of the cartridge case 9 any more, at the moment, the cartridge case 9 can be held and pulled downwards, the cartridge case 9 can move downwards along the track of the chute 41 of the partition plate seat 11, when the partition plate seat 11 is fixed with the nail head 6 through the fastening screw 46, as the cartridge case 9 moves down, the slot at the upper end of the cartridge case 9 is exposed.
When the notch at the upper end of the cartridge clip shell 9 is exposed outside, a worker can select one of the appropriate nail guiding grooves 37 according to the length of the straight nails of the strip nails to clamp the head of the strip nails into the cartridge clip shell, the straight nail at the lowest part of the strip nails is pressed on the upper surface of the top head piece 27 at the moment, then the two rows of the strip nails are respectively pressed into the left nail guiding cavity 13 and the right nail guiding cavity 14, the top head piece continuously moves down under the pressure action of the strip nails along with the loading of the strip nails, at the moment, the top head piece 27 presses the top head push rod 24 downwards through the clamping plate 29, the top head push rod 24 continuously compresses the top head spring 23 downwards along with the top head spring 23, the top head spring 23 generates upward elastic force, after the two rows of the strip nails are completely installed, the cartridge clip shell 9 can move upwards along the track of the sliding groove 41 through the matching between the sliding strip 42 and the sliding groove 41, finally, the positioning hook 31 at the upper end of the positioning handle 30 moves to the, with the partition plate 12 fixed, once the positioning hooks 31 are hooked in the positioning notches, the cartridge case 9 can be fixed by the partition plate 12.
When the cartridge clip shell 9 is loaded with two rows of nails and fixed again, the straight nail at the top of the nail is pushed into the nail outlet groove 7 of the nail head 6 under the elastic force of the top spring 23, because the nail head cover plate 8 covers the nail head 6, under the limitation of the nail head cover plate 8, the straight nail at the top of the nail can be stably positioned in the nail outlet groove 7, at the moment, two straight nails are simultaneously arranged at the left side and the right side of the nail outlet groove 7, the two straight nails are respectively the straight nail at the top of the nail in the left nail guide cavity 13 and the straight nail at the top of the nail in the right nail guide cavity 14, then the straight nail gun can be opened, after the straight nail gun is started, under the action of the piston 3, the firing pin 4 impacts forwards along the trajectory of the gun path 5, at the moment, the left needle head 18 at the front end of the firing pin 4 impacts the straight nail at the left side of the nail outlet groove 7, the right needle head 19 at the front end of the firing pin 4 impacts the straight nail at the right needle at the right side of the nail, finally, two straight nails are all driven out of the nail head 6, and the double-nail driving work is finished.
After one nailing operation is completed, the row nails in the left nail guide cavity 13 automatically move upwards under the action of the top spring 23, the uppermost straight nails of the row nails in the left nail guide cavity 13 sequentially pass through the upper end cavity opening of the left nail guide cavity 13 and the left upper nail hole 16 to enter the left side of the nail outlet groove 7, the row nails in the right nail guide cavity 14 automatically move upwards under the action of the top spring 23, the uppermost straight nails of the row nails in the right nail guide cavity 14 sequentially pass through the upper end cavity opening of the right nail guide cavity 14 and the right upper nail hole 17 to enter the right side of the nail outlet groove 7, the two rows of row nails sequentially move along the trajectories of the nail guide groove 37 and the limiting groove 36 corresponding to the nail guide groove 37 in the upwards moving process, and the stability of the two rows of row nails during automatic nailing is ensured to the maximum extent, when the nail outlet groove 7 is provided with two straight nails again, the nail can be nailed again, and the circulation is repeated, so that two straight nails can be simultaneously driven out by each nailing.
In conclusion, the cartridge case 9 of the present invention can be loaded with two rows of nails simultaneously, so that the nail outlet slot 7 of the nail head has two straight nails simultaneously, when the striker 4 strikes the nail forward, the left striker 18 and the right striker 19 at the front end of the striker 4 can eject two straight nails simultaneously, thereby achieving the effect of double-nail driving.
Divide the nail structure including locating the back branch nail pole 38 at through-hole 15 rear hole wall center, locate the preceding branch nail pole 39 at through-hole 15 front hole wall center, preceding branch nail pole 39 rear end and preceding branch nail pole 39 front end between have the regulation clearance 40, the existence of regulation clearance 40 makes preceding branch nail pole 39 and back branch nail pole 38 structure non-integratively, both can have certain elasticity, thereby adapt to arrange on the nail to divide nail pole 39, the extrusion of back branch nail pole 38 to preceding branch nail pole 39, avoid extrudeing each other and lead to the circumstances that the nail in-process appears blocking and pausing, the top piece 27 that is the U type simultaneously can be through adjusting clearance 40 smoothly with arranging the last straight nail of nail into to going out the nail inslot, guarantee that the removal of top piece 27 can not receive the restriction of branch nail structure, guarantee the smooth and easy removal of top piece 27.
The front side of the gun handle 2 is provided with a connecting block 43, the connecting block 43 is connected with the lower part of the partition plate seat 11 through a connecting plate 44, the partition plate seat 11 can be further stabilized by the connecting plate 44, the front end of the connecting plate 44 is fixed with the connecting block 43, the rear end of the connecting plate 44 is fixed with the partition plate seat 11 through a fixing screw 45, and the gun handle is convenient to disassemble and assemble by the fixing mode.
The upper end of the clapboard seat 11 is fixed with the nail head 6 through a fastening screw 46, and the fixing mode is convenient for disassembly and assembly.
The nail head 6 and the nail head cover plate 8 are fixed with the front end of the gun body 1 through a locking screw 47, a backing plate 48 is arranged between the nail head cover plate 8 and the head of the locking screw 47, and the backing plate 48 can effectively play a role in preventing abrasion.
