First of all, I put down the punching knife and saw that there were two black hexagonal top threads on the cylinder where the knife was loaded. I unscrewed them with three hexagon wrenches (found in the toolbox) and the knife came down. If the top thread can't be unscrewed, hold the blade with big pliers and find something hard to knock the pliers off. Maybe the handle and sleeve are too tight.
Before positioning and drilling, check whether there are other hard impurities such as staples and glue hardening impurities in the bound materials, because it is easy to damage the drilling tool and affect its service life, so it must be removed; Check whether the financial documents and other information are neat. If it is not neat, it is easy to cause uneven stress on the drilling tool and easy to break.
Check whether there are plastic plates, cardboard and other non-paper materials in financial documents and other materials; In the experiment, just use a punching knife to punch holes in a piece of paper. For example, if you can't punch or overshoot, you need to adjust the adjusting nut on the rack shaft until a piece of paper is just punched. Observe whether the paper scraps in the glove box are full, and if so, empty the glove box.

Matters needing attention in the use of voucher binding machine:
1. When drilling, first check whether the required drilling data are placed in the position where the drill can hit, so as to ensure that there is a certain margin around the drilling position, otherwise it may be bound badly;
2. If it is a financial binding machine with a handle, special attention should be paid to uniform force and moderate speed when punching; For a binding machine with a handle, it is not laborious to punch holes continuously under normal circumstances. If it becomes difficult to punch holes suddenly, stop the operation immediately. This may be the phenomenon that the drill bit is blocked by paper scraps, and the paper scraps inside should be cleaned up with special tools for drilling the drill bit. However, after the bit is used to a certain extent, the blade will become dull, so contact the maintenance personnel to sharpen the bit before using it.
3. For the maintenance of drilling tools, the following conditions need to be maintained: when drilling is difficult or it is impossible to drill through holes during use, the drilling tools should be maintained; If there is perforation, such as perforation failure, burning smell, black bit color, stuck alarm, or one or more of the above phenomena, the bit should also be kept sharpening. If you can't maintain it yourself, contact the maintenance personnel for handling, or replace it with a new drilling tool.
