Abstract (en)
A hammer position adjustment mechanism for a buttonhole cutting device of a buttonholing machine is adapted to change the length of a buttonhole to be cut on a fabric, and includes a hammer, a locating block connected to and driven by a driving unit to move vertically, a slidable hammer holder connected to the hammer and slidably assembled to the locating block to move vertically along with the locating block, a driving source for driving the slidable hammer holder to move laterally in ³-axis direction through meshing of a rack provided on the slidable hammer holder with a gear toothed shaft connected to the driving source. With these arrangements, the hammer can be adjusted in position with a simplified mechanism that includes fewer parts to reduce the manufacturing cost of the buttonholing machine and occupies less operational space on the buttonholing machine to facilitate convenient buttonhole stitching.
