Description of the embodiments

The utility model is further described in detail below with reference to the drawings and examples.

Embodiment, combining the drawing, a press from both sides flat nail rifle, including rifle body 1, cylinder 6, clamp mouth connecting rod 7, the rifle body includes clamp cutter 2 again, presss from both sides mouth anvil up seat 3, presss from both sides mouth anvil down seat 4, side board 5 and press from both sides flat nail 8, presss from both sides mouth anvil down seat 4 to be equipped with clamp cutter complex book nail mouth 9. The code clamping nails 8 are arranged in rows in the gun groove and are sent to the nail arranging opening 10 by one, when the pressing knife 2 walks downwards, one code clamping nail is pressed down and sent to the nail rolling opening 9, and the iron wires 11 are clamped by the code clamping nails and then are curled to wrap the iron wires.

The side plate 5 is positioned outside the cylinder 6, the clamping connection rod 7 and the clamping anvil lower seat 4, the side plate 5 is provided with a limiting groove 12, and the end 14 of the limiting groove 12, which is far away from the piston rod 13, is upwards bent in an arc shape.

The outer end of the clamping anvil lower seat 4 is pivoted with the clamping anvil upper seat 3 through a side plate pin 15, and two ends of the side plate pin 15 are fixed on the side plate 5.

The inner end of the clamping anvil lower seat 4 is pivoted with the outer end of the clamping connecting rod 7 through a clamping connecting rod front pin 16, wherein the inner end of the clamping anvil lower seat pivoted with the clamping connecting rod front pin is of an opening 17 structure, and when the clamping anvil lower seat is impacted by a pressing knife, the clamping anvil lower seat can not drive the clamping connecting rod to rotate even if slightly rotated in sequence. The jaw connecting rod is not pushed by the reverse acting force to release, and the self-locking function is lost.

The inner end of the clamping connecting rod 7 is connected with the piston rod 13 through the cylinder connector 18, the inner end of the clamping connecting rod is limited in the limiting groove 12 through the clamping connecting rod rear pin 21, the clamping connecting rod rear pin 21 can only slide in the limiting groove, the piston rod pushes the inner end of the clamping connecting rod 7 to move along the limiting groove 12, the outer end of the clamping connecting rod 7 simultaneously rotates and can drive the inner end of the clamping anvil to rotate, and the conversion of the rolling nail mouth 9 between the rolling nail position A and the nail withdrawing position B is realized when the clamping anvil rotates.

When the nail rolling opening 9 is positioned at the nail rolling position, the lower seat of the clamping opening anvil is contacted with the upper seat of the clamping opening anvil at two planes C at the inner side of the nail rolling opening. Even if the piston rod pushes the jaw connecting rod to move forwards, the jaw anvil lower seat can not rotate relative to the jaw anvil upper seat any more.

The clamping jaw anvil upper seat 3 above the upward tilting end 14 of the limiting groove is provided with an inner concave arc groove 19, a first arc surface 20 is arranged in the middle of the clamping jaw anvil lower seat 4, a second arc surface 22 is arranged in the middle of the clamping jaw connecting rod, and when the nail rolling opening 9 is positioned at the nail rolling position, the inner end of the clamping jaw connecting rod can slide into the concave arc groove from between the inner concave arc groove 19 and the first arc surface 20 of the clamping jaw anvil upper seat, and at the moment, the first arc surface 20 and the second arc surface 22 are attached.

When the nail rolling opening is positioned at the nail rolling position, the inner end part of the clamping opening connecting rod can slide into the concave arc-shaped groove 19 from the position between the concave arc-shaped groove 19 of the upper seat of the clamping opening anvil and the first arc-shaped surface 20. The cylinder can be designed to be quite large, the cylinder can only push the clamping connection rod to move, the impact force of the clamping anvil lower seat, which is subjected to the pressing knife, can be transmitted to the clamping connection rod through the first arc-shaped surface 20 and the second arc-shaped surface 22, and the clamping connection rod transmits the force to the wall of the inner concave arc-shaped groove 19 to form a self-locking force function, so that the resistance force is from the clamping anvil upper seat instead of the cylinder when the clamping anvil lower seat is impacted by the pressing knife.

The lower nail rolling opening is positioned at the nail rolling position, the cylinder is started, the piston rod pushes the inner end of the clamping opening connecting rod to move forwards along the limiting groove, the outer end of the clamping opening connecting rod rotates to drive the clamping opening anvil to rotate, the nail rolling opening is tilted, and the nail rolling opening can work with the pressing knife after being tilted. When the nail rolling opening withdraws the nail, the cylinder moves back to drive the inner end of the clamping opening connecting rod to move back, the outer end of the clamping opening connecting rod rotates reversely to drive the inner end of the lower seat of the clamping opening anvil to lift up, so that the nail rolling opening reaches the nail withdrawing position, and the iron wire can be conveniently removed.
