What's wrong with the live fish guy?

The reason why the live fish can't be pulled is that the fit clearance between the transmission gear and the slider is too large. There are abrasive particles in the transmission gear. The spindle is bent and stuck, and the rocker arm shakes the groove of the slider hard. Solution: Add a gasket at the bottom of the transmission gear shaft to reduce the gap between the transmission gear and the slider. Replace the slider and toothed disc with missing teeth. Correct the spindle. Clean the device and apply vaseline oil for lubrication. Live fish buckle is to wear gills. Adjust the wheel of the live fish buckle to the loosest position, then open the first fish buckle and hang it on the wheel through the hole in the wheel, so that the wheel will not go out.
