The key component is in the handle of the saw.
The saw has two grooves. Two gears connect to a connecting rod. A buckle is welded onto the connecting rod. The buckle fits perfectly into the groove.
In this way, as long as the upper gear rotates, it will drive the saw outward, and the lower gear will rotate in the opposite direction, which will drive the saw back.
Overall, it contains a motherboard, which specifies the location of each component.
As instructed, install the gears first. Next, install the small parts. After that, wind up the mainspring.
A clip is installed on one of the springs on the motherboard.
Following Lin Ying's instructions, Guo Minsheng assembled one of the mainsprings, installed the outer casing, wound the mainspring using the external handle, and then installed it into the position with the latch, ensuring that the latch and the mainspring's latch were in the same position.
Everyone knows what this means. When you press this latch in, the internal latches will loosen. This will release the winding mechanism inside, causing the bearing inside to rotate.
The other one doesn't need to be tightened either; just install it according to the drawings.
Then comes the important part. This saw is used back and forth continuously, and to make it usable back and forth, you have to alternate between loosening and tightening it on both sides.
Guo Minsheng took the handle he had just wound up and placed one on each side, then added two small rollers. He then attached a geared iron chain. Everyone immediately understood.
When this side is tightened or loosened, the gears turn, which winds the spring on the other side. Of course, there's also an automatic switch here.
Before you relax your grip on this side, the other side won't release the pressure. Only after you relax your grip on this side will you trigger a switch, and the other side will then release the pressure.
This way, you can achieve the effect of going back and forth, instead of running out of energy on both sides halfway through.
After assembling the other half, the next step is to assemble the entire outer shell.
Once everything is done, it will be quite a challenge for everyone.
Guo Minsheng looked at the product with great satisfaction and asked, "Factory manager, should we find something to try?"
Before Jiang He could speak, Commander Lu chimed in, "Try it! Of course we should try it! Quickly find a piece of wood and see if this thing works!"
Upon hearing this, everyone rushed out and returned with a wooden stick as thick as an arm.
After watching everyone put the wooden sticks away, Guo Minsheng walked over and pressed the button.
Just as everyone heard the sound of the clockwork, the saw had already moved forward and backward several times.
In other words, the spring inside has been wound up and down several times.
Guo Minsheng didn't put the saw on the wood first; instead, he released the button. The saw stopped the instant the button snapped back.
He then realized that the teeth on the top and bottom of the spring inside were used to shut it off.
Only then did he begin to use the saw.
When the button was pressed again, the saw started moving back and forth rapidly once more.
Everyone held their breath, watching as the saw walked up to the stick. A few seconds later, the stick snapped.
"good!"
Commander Lu couldn't help but say something.
Jiang He, standing nearby, couldn't help but marvel at the device: "Next, we need to conduct actual tests to check its wear and tear, as well as its safety. If it really works perfectly, this thing is low-cost, and most importantly, it doesn't require oil or electricity! It will definitely save a lot of money!"
Are chainsaws expensive? They're certainly not cheap. But it's not like the military can't afford them.
The real expense isn't the chainsaw, it's the oil! If this thing could actually be made, it would not only be cheaper than a chainsaw, but more importantly, it wouldn't use any oil or electricity!
Commander Lu laughed and said, "Whether it's suitable or not depends on whether it can be used for logging! I've taken the equipment. I'll give you an answer the day after tomorrow! You can pay for these young men's food expenses first, and I'll pay you back later!"
Jiang He laughed and scolded, "Do you think I need two crooked and ugly people like you? Just promise me that you'll come to me when mass production starts!"
Commander Lu smiled and said, "You'll have to ask the person who gave me the blueprints. But I can guarantee that if they agree, I'll definitely come to you."
Commander Lu left with the things, and Guo Minsheng, who was standing to the side, said with some regret: "Factory Director, they just let them take them like that?"
Seeing him acting like his own child had been taken away, Jiang He couldn't help but scold, "Don't worry, if there's nothing wrong with this, you'll have plenty to get your hands on later! Here, these are food coupons and money. You take everyone out to eat."
