Projection 41 of the fastening end face of the locking nut provided with the embedded groove.
The external diameter of the attaching nut is provided with annular knurl 42.
The regulation bearing pin is provided with inner hexagonal hole 31 in the one end being connected with work feed connecting rod.
Embodiment one：
As shown in Figure 1, Figure 2, Fig. 3, Fig. 4, a kind of stitch adjustable gun type closer, including work feed rocking bar 10, work feed connecting rod 20.Send
One end of cloth connecting rod drives rotation by cam 01, and the other end connection work feed rocking bar of work feed connecting rod drives work feed rocking bar to swing, driven
Dynamic cloth feeding mechanism realizes that work feed is operated.The oscillating quantity of work feed rocking bar controls the size of cloth feed amount, by adjust work feed connecting rod with
The link position of work feed rocking bar, can be achieved the adjustment of cloth feed amount, so as to adjust the distance of portable sack closer stitch.
Work feed rocking bar is provided with rocking arm 11, and rocking arm connects slotted eye 12 provided with strip, connects width K=6mm of slotted eye.Connection
The back side 14 of rocking arm is provided with groove 15, and wide K=6mm of groove is identical with the width for connecting slotted eye；
