After two days of entanglement, the special processing equipment that Li Mo handed over to the two machinery factories was finally completed, and he found someone to move it to a specially vacated office in the Red Star Stationery Factory.

Counting the cost of customization, material processing, etc., the modification price of such a mechanical pencil machine is about 7,000 yuan, accounting for about one-tenth of the price of an automatic pencil making machine.

If compared to the millions of machines in the Plane Marketplace, it is cheaper.

But cheapness is not the goal, the important thing is whether you can make what you want.

Under the gaze of Chu Shanhu and several confused deputy factory directors, Li Mo sat in front of the machine that looked a bit like a loom, and also looked at the manual in his mind with a little nervousness.

Having a machine is only the first step, and the more important step is how to use this strange-shaped guy to manufacture and process the key parts of the mechanical pencil, especially the mechanical refill, and then assemble them together.

"Buzz"

As Li Mo pressed the open button, the whole machine began to hum.

Compared with the traditional 5,000-watt mechanical pencil machine, this specially processed modified pencil machine with some cutting parts has a power of about 10 kilowatts, which is twice that of an ordinary machine.

Although the power consumption is much higher than before, once successful, it can create tens or even hundreds of times more value than before.

At this time, Li Mo's mood was no less than the excitement when Watt invented the steam engine.

"Zila-"

"Squeak-squeak"

"Click-Click-"

After trying hard to suppress his feelings, Li Mo patiently began to work, using this new tool to polish and assemble mechanical refills, match the barrel, and inlay parts such as paddles that he couldn't even tell the function...

The factory directors next to them couldn't help but be in a daze when they watched Li Mo's every move, which was completely different from the mechanical pencil assembly method they were familiar with before, not only to assemble ready-made accessories, but even to cut and polish parts on site.

"No... It's the other way around... It doesn't seem like that..."

Staring at the mechanical pencil assembly drawings in his mind, Li Mo repeatedly tried how to use this machine to assemble parts in place, just like when he was a child assembling toy racing cars.

It lasted for more than half an hour, and Li Mo, who had never touched a mechanical pencil machine, gradually mastered the functions of each area of the entire machine, and the sample pen with a black shell with half the radius of an ordinary mechanical pencil in his hand gradually revealed the true face of Lushan.

"Whew~ Fortunately, I haven't forgotten all the things I did in the metalworking internship..."

After another half an hour, Li Mo finally assembled his first semi-automatic mechanical pencil according to the instructions in his mind.

Probably because of the hand, and he doesn't have much experience in mechanical work, the first product in Li Mo's hand is still a little rough, and the fit in some places is not in place.

But the basic functions should be able to be played.

Although it took a lot of time for this pen to be born from Li Mo's hand, if it was practiced, a skilled worker could completely get a batch of about ten pens in five minutes.

"Click, click..."

In addition to the pencil button at the top, there are three gears on the side of the cap of this mechanical pencil, similar to the DPI speed change button on the gaming mouse, which can be switched between "straight line drawing", "curve drawing" and "free drawing".

After pressing the function switch button several times, Li Mo raised his head and said to Deputy Director Chang Hanming, who was still in a daze, "Please ask Deputy Director Chang to help find a piece of paper, and find some compass rulers or something." ”

In his heart, he continued to say another sentence, and next, it was time to witness the miracle.

"Huh? Oh okay..."

Hearing this, Chang Hanming, who still couldn't figure out what gimmick the young boss was going to do, hurriedly walked out of the office and returned to his room, looking for what Li Mo needed.

After all, it was a stationery factory, and soon, a pile of professional drawing blank paper, brand-new ruler compasses and other items were placed in front of Li Mo.

"First Drawing Test with Semi-Automatic Mechanical Pencil, Straight Line Drawing"

Silently muttering in his heart, Li Mo switched the mechanical pencil function to straight line mode.

Immediately, two needles protrude from two thin holes near the nib, forming a three-point layout together with the refill, and a side sliding pick is stuck between Li Mo's middle finger and ring finger, holding the pencil to his right hand in a special way.

If you're drawing other shapes, the paddle, which also slides up and down, needs to be fixed between the other two fingers – the index finger, the middle finger, or the ring finger of the little thumb.

In addition, there are nearly 10 needle-like holes of different thicknesses at the port of this mechanical pencil case, like a miniature hornet's nest, and different auxiliary pins will poke out of it as the function is switched.

Although he personally created this pencil, he couldn't explain it at all when he asked Li Mo to explain where and where these needles were placed, as if they naturally appeared after making this pen.

According to the gesture requirements on the manual, Li Mo held the pen and moved his little thumb outward slightly, and then held a mechanical pencil in his hand and drew a line on the white paper.

As if relying on the guidance of two sleek needles at the top, Li Mo felt that in addition to himself, there were two other external forces controlling the direction of the pen tip, as if he was gliding along a track.

At the end of this line, Li Mo deliberately wanted to draw a curve, but due to the influence of the paddle stuck between the middle finger and ring finger, he finally drew a folded line very unnaturally.

In a different place from the original straight path, the lead core did not touch the paper due to the two auxiliary pins, so there were no other traces, and the painting needed to be replenished again.

Then Li Mo took a transparent plastic ruler and made a comparison along the straight line.

Except for the beginning and corner, the line drawn by Li Mo casually was accurate and perfectly fit the ruler.

In Li Mo's opinion, the only drawing flaw is also because the initial product he made is too rough.

In the face of such a scene, although Li Mo did not explain anything, the directors and deputy directors of the technical workers next to him also understood, and at this time, they all stood there, their mouths slightly open, and they were so shocked that they couldn't speak.

This... Aren't you dazzled?

With a pencil that doesn't look very good, you can draw a standard straight line?!

Ignoring the horrors of these conservatives, Li Mo continued to test another important function of the mechanical pencil, arc drawing at different angles.

Due to cost and equipment limitations, the current most primitive mechanical pencil can only draw arcs in units of ten degrees, but this has basically included the commonly used arc angles, which is more than enough for non-accurate drawing, and because it is assisted by the straight line function, the arc radius is not a limit.

What's more, those who need to accurately draw all kinds of strange angles are not within Li Mo's target customer range.

"God... God..."

Seeing that Li Mo could draw standard straight lines and arcs at will without the help of any equipment, Chang Hanming and several other deputy factory directors were amazed - this technology, even if it won the National Technological Progress Award, is more than enough!
