(1) The whole machine consists of a pulley, a spring seat, a tongue block and a main shaft to form a power transmission mechanism.
(2) A punching mechanism consisting of a crank, a connecting rod, a straight shaft, and a top and bottom mold.
(3) The start control mechanism consists of a bumper, a shutter and a tie rod.
The pulley set is idly rotated on the upper shaft, the tongue block is fixed on the upper shaft, and the tongue block is installed in the tongue block seat, and is controlled by the shutter and the top spring. When the gate is pulled down by the pedal, the gate is released. When the tongue block and the tongue block collide with the pulley, the spindle is rotated by the pulley, and the straight shaft is operated up and down by the crank slider mechanism. The upper mold mounted on the lower end of the straight shaft is punched up and down with the straight shaft, and cooperates with the lower mold mounted on the base to punch the metal buckle and fix it on the fabric.
